Have you been struggling with constant hunger, low energy, and disappointing results despite religiously counting calories? You're not alone. A recent survey revealed that 28% of people trying to lose body fat consume dangerously low calories – between 1,500-1,700 daily – potentially sabotaging their long-term success.


Mario Tomic, a fitness coach with over a decade of experience helping thousands transform their bodies, shares critical warning signs that your calorie intake might be too low. With more than 400,000 YouTube subscribers benefiting from his science-based approach, Mario reveals how to spot and fix the common pitfalls of excessive calorie restriction. Read on to discover if you're unknowingly undermining your progress and learn how to adjust your diet for sustainable results.

Your Strength Is Declining

"If you're consistently getting worse training performance and you're not even that lean, you have a problem," Mario warns in his post. He explains that strength loss typically starts subtly – fewer reps than usual, then eventually reducing weights on main lifts.

"Poor training performance is how people end up losing lean muscle, becoming more skinny fat, and slowing down their metabolism," Mario cautions. According to him, beginners and intermediate lifters should maintain or even gain strength until reaching 10-15% body fat.

You're Losing Weight Too Fast

Mario emphasizes that rapid weight loss often backfires: "If you're above 20% body fat, aim to lose 1% of your body weight per week." For someone at 200 pounds, that's a maximum of two pounds weekly.

For those at or below 20% body fat, the target changes: "My recommendation is to lose between half a percent to about three-quarters of a percent of your body weight per week." This measured approach helps preserve muscle mass while ensuring sustainable fat loss.

You Can't Stop Binge Eating

"Most people tend to blame a lack of discipline, but the reality is the plan itself is set up for you to fail," Mario points out. He describes the typical cycle: 4-5 days of severe restriction followed by weekend binges, resulting in minimal progress despite constant struggle.

You're Below Your Minimum Calorie Threshold

"It's often mentioned that the lowest calorie intake you should have is 10 calories per pound of your target body weight," Mario explains. A target weight of 180 pounds means never dropping below 1,800 calories daily.

He says that this isn't a starting point: "This might be an endpoint for the last few weeks of a cut if you're getting super shredded, but generally, the rule stands as a soft limit where if you get under these levels, you're probably doing something that's unsustainable."

Your Hunger Is Uncontrollable

While some hunger during fat loss is normal, Mario explains the difference: "If you eat whole, healthy, unprocessed foods, get your protein, get your vegetables, drink enough water, sleep well, you'll be able to manage it well."

However, he warns, "The problem is when your calories are so low that you're hungry all the time and consistently obsessing about food." When meals never satisfy you, it's time to reassess your intake.

You Can't Focus at Work

"Getting lean is very important, but it should not come at the expense of your career, your family, and your life in general," Mario emphasizes. Constant fatigue, difficulty concentrating, and irritability are clear signs your calories are too low.

You're Not Tracking Accurately

"Most people cannot accurately estimate their calorie intake," Mario notes. He highlights common pitfalls: "We got labels that are a little bit off, and we also got eating out, which can be off as well." This inaccuracy often leads to unintentional severe restriction.

You're Experiencing Physical Symptoms

Mario points out that dizziness, headaches, and sleep problems are serious red flags. When these symptoms appear, he advises: "I would highly recommend that you increase your calories by 10% and then recalibrate from there."

You're Stuck in the Quick-Fix Mindset

"Instead of trying to fix a decade of bad eating habits in two, three months of crash dieting, take a more long-term patient approach," Mario advises. The goal isn't just reaching a target weight – it's creating sustainable habits.

You're Not Moving Enough

Mario shares a crucial strategy for maintaining higher calories while losing fat: "I highly recommend that you start walking 7,000 to 10,000 steps per day, which will help you create that calorie deficit without having to starve yourself."

For those experiencing multiple warning signs, Mario suggests "doing a diet break to maintain calories for two to four weeks to let some of that diet fatigue dissipate." Remember, sustainable fat loss isn't about reaching your goal weight as quickly as possible – it's about building healthy habits that last a lifetime. Instead of cutting calories to the absolute minimum, focus on maintaining the highest possible intake that allows for steady, consistent progress.

If you feel like your metabolism isn’t working efficiently, you aren’t alone. Kelsey Kunik, RD, is a nutritionist who tries to help people “overcome overeating without dieting.” In a recent Instagram video, she discusses metabolism and how yours could be damaged because of dieting. “Do you ever feel like other people are ‘blessed’ and you’re ‘cursed’ when it comes to your metabolism??” she writes in the beginning of the post, going on to explain why and what you can do about it. Body Network also consulted with our Resident RDN, The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, co-author of the Flat Belly Cookbook for Dummies, to offer her input on the topic.


Some People Try Dieting to Speed Up Their Metabolism, But It Has the Opposite Effect

Kelsey_Kunik_graciouslynourished2graciouslynourished/Instagram

In the video, Kunik explains that oftentimes when someone believes their metabolism is damaged, they might go to the wrong extremes. “That might lead you to dieting to lose weight or speed things up, but the truth is that dieting, especially dieting on and off over several years, can have a massive impact on how efficiently you burn calories,” she says.

Here Are the Signs and Symptoms Yours Needs Help

Kelsey_Kunik_graciouslynourished1graciouslynourished/Instagram

“While this is NOT medical advice and it’s not the ONLY possible cause of these symptoms, your metabolism could use a little help if you experience any of these,” she says.

Holding Onto Extra Weight

Are you feeling heavier than usual? The first sign is “holding on to extra weight,” says Kelsey.

Fatigue

The second sign your metabolism is damaged? “Feeling tired,” she says.

Constipation

Are you having trouble going to the bathroom? “Number three on the list is constipation,” she says.

Always Feeling Cold

Are you getting the chills more than usual? The fourth sign your metabolism is damaged is that you are “always feeling cold.”

Hormone Imbalances

Are you feeling all over the place or unusually hormonal, even when it’s not that time of the month. Number five, “hormone imbalances,” she says.

The Answer: Feed Your Body with Nutrients

What should you do about it? “And the answer to repairing your metabolism is NOT another diet,” she continues. “When your body is given nourishing food on a regular basis that’s balanced with high protein, fiber, quality carbohydrates, healthy fats, and plenty of fruits and veggies, it begins to trust that food is available and your metabolism can start to HEAL itself. Your metabolism will NOT improve when your body is in a constant flux of starvation and excess — as if you needed another reason to stop dieting!”

Why Your Metabolism Could Be “Tanking,” According to Collingwood

Collingwood agrees on all points. “All of these could be signs that your metabolism is tanking,” she says, offering reasons why it may be happening. “It could be from lack of physical activity, poor diet, eating too little, getting too little sleep, or a variety of other reasons,” she says. “When under stress, the body tries to hang on to what it has which means lowering metabolism to prevent weight loss and cause fatigue and other symptoms.”

3 Ways Walking Targets Belly Fat Better Than Running Says Nutritionist

Have you ever felt frustrated stepping on the scale, wondering if your weight loss efforts are actually working? You're not alone. While the number on the scale might not budge, your body could be going through important changes that signal progress.

Autumn Bates, a certified clinical nutritionist with a master's in nutrition and human performance, has helped thousands achieve their weight loss goals through science-backed strategies. Through her own postpartum weight loss journey and work with clients, she's identified three distinct phases of healthy fat loss that can help you recognize when you're on the right track.

Phase 1: The Reset and Rebuild Stage

"Many people who have tried to lose weight in the past are chronically eating low calories and overexercising," Bates explains in her post. This first phase focuses on healing your metabolism and rebuilding strength. You might be in this phase if you notice these signs:

1. Experiencing persistently low energy levels

2. Having difficulty losing weight despite strict dieting

3. Struggling with poor sleep quality

4. Gaining weight easily when eating starches or treats.

During this phase, Bates recommends focusing on protein, healthy fats, and fiber while incorporating gentle movement and resistance training. "This helps signal to your body that it's not in a state of starvation and can start letting go of body fat," she notes.

Phase 2: The Transformation Stage

After establishing a strong foundation, the second phase is where visible changes begin. According to Bates, "This is when the magic really happens." You'll notice these five signs:

5. Clothes fitting looser

6. Body measurements decreasing

7. Significantly increased energy levels

8. Growing physical strength

9. Steady scale progress.

"During my eight-week transformation phase, I lost about 16 pounds, with most of it being pure body fat," Bates shares. This success comes from improved metabolic flexibility and insulin sensitivity established in Phase 1.

Phase 3: The Maintenance Adjustment

The final phase requires careful attention to avoid reversing progress. "This phase tends to confuse many people because they've been eating until satisfied for so long, but suddenly feel hungrier with the same amount of food," Bates explains. Look for these signs:

10. Increased hunger despite maintaining your usual portions

11. Workouts becoming more challenging

12. Noticeably lower body fat percentage

13. Higher muscle mass relative to body weight.

Making Smart Adjustments

During Phase 3, Bates recommends increasing food intake strategically: "What people do better with during this phase is either high-quality sources of fat or some high-quality sources of medium to high glycemic load carbohydrates." Good options include:

Healthy Fats:

  • Avocados
  • Cheese
  • Olives
  • Nuts and seeds
  • Natural nut butters

Quality Carbohydrates:

  • Sweet potatoes
  • Quinoa
  • Buckwheat
  • Red lentil pasta
  • Properly fermented sourdough.

Avoiding Common Pitfalls

Before making adjustments, Bates advises checking if increased hunger is truly related to Phase 3 by asking:

  • Have workouts become more challenging?
  • Has stress increased?
  • Has sleep quality decreased?
  • Have you recently included more processed foods?

The answer to these questions will help determine if you need to adjust your nutrition or address other lifestyle factors first.

The Importance of Proper Nourishment

"Body recomposition, where you're losing fat while maintaining muscle mass, is much easier to sustain," Bates emphasizes. This approach nourishes the body, reduces hunger, and produces better results than simply eating less and moving more.

Remember that progress isn't always linear, and the scale doesn't tell the whole story. By understanding these three phases and their signs, you can make informed decisions about your nutrition and exercise routine, leading to sustainable, long-term results.

Ever feel like you're doing everything right with your diet, but your body isn't responding anymore? You're not alone. While counting calories seems straightforward, your body might be secretly fighting against your weight loss efforts. Thomas DeLauer, a nutrition coach for professional athletes with over 3.68 million YouTube subscribers, reveals the critical warning signs that your body has stopped burning fat effectively. Learn how to identify these signals and, more importantly, how to fix them.


Persistent Cold Sensitivity

If you're constantly reaching for extra layers, your diet might be the culprit. "If you restrict your calories right now, I don't think you'll start feeling cold tomorrow or the next day or even next week, but over a period of time, weeks, months, years, you might certainly start noticing a reduction in your body temperature," DeLauer warns in his post. Research from the Journal of Aging confirms significantly lower body temperatures in people following caloric restriction.

Thyroid Function Changes

DeLauer points to compelling research from the Journal of Endocrinology and Metabolism about thyroid impact. "I don't want to scare you and make you think that if you restrict calories, you're going to plummet your T3 levels. First of all, your T3 levels will come back. The thyroid is very resilient," he explains. However, long-term caloric restriction can lead to decreased T3 hormone levels, affecting your metabolism.

Strength Starts Declining

"I'm not talking about just general fatigue," DeLauer clarifies. "That can definitely happen with caloric restriction, but I'm talking more about actually feeling like you have less strength." He cites research showing a concerning 12.4% reduction in strength during weight loss. The good news? This can be mitigated by maintaining adequate protein intake during caloric restriction.

Sleep Quality Deteriorates

"If you start noticing that your sleep is going to garbage, this is a very good indicator that you're eating too little, and this can happen very fast," DeLauer warns. "This can be something that can happen as quickly as two or three days into extreme caloric restriction." Research involving 4,400 people revealed that consuming less than 16% of calories from protein led to worse sleep quality and difficulty falling asleep.

Energy Levels Plummet

"When you first restrict calories, you feel really good, you're reducing inflammation, you get more energy, you actually feel more alive and more energetic, and that lasts for a couple of months sometimes," DeLauer explains. "But then unfortunately, what ends up happening after that is that you end up in a situation where your body has to go into preservation mode."

Your Body Enters Power-Save Mode

DeLauer uses a brilliant analogy: "It's like when your iPhone gets below 20% and it goes to the yellow battery bar and it kind of downregulates the performance to preserve battery life. That's kind of what happens with your body." This power-saving mode affects everything from your workouts to your daily activities.

Mood Changes Become Noticeable

"It's almost like you have a more cynical outlook on life," DeLauer notes. "This isn't like short-term hanger. This is more long-term mood disorders that end up happening as a result of being in caloric restriction mode." The Journal of Health Psychology confirms this connection between dietary restriction and increased irritability.

Anxiety Levels Rise

"Our ability to withstand and our resilience to be able to deal with caloric restriction goes down as we age," DeLauer explains. He references a 2022 study showing how caloric restriction can increase anxiety, particularly in older individuals. This effect becomes more pronounced with age, making proper nutrition even more crucial.

Exercise Performance Suffers

"You are making this problem even worse because if you're not eating enough protein at baseline and then you're adding exercise on top of it, you're definitely not getting enough protein," DeLauer emphasizes. This creates a harmful cycle where inadequate nutrition compromises both performance and recovery.

Recovery Time Increases

DeLauer stresses that recovery becomes compromised when calories are too low. He explains that increased protein demands from exercise, combined with insufficient caloric intake, can significantly impair your body's ability to repair and rebuild after workouts.

Stress Hormones Spike

"You have increases in adrenaline, in cortisol, in epinephrine, and that will definitely impact your sleep," DeLauer notes. These hormonal changes don't just affect sleep – they can impact everything from mood to fat storage, especially in older adults who are more sensitive to hormonal fluctuations.

Metabolic Flexibility Diminishes

The solution isn't to abandon your weight loss goals, but to approach them strategically. DeLauer advises, "Don't go back to eating in a surplus and don't go back to eating how much you were eating at your heavier weight. Just slightly increase your calories and try to maintain your weight for two to three weeks, and then go back into caloric restriction, and you'll find that that really recharges you quite well."

You might be excited that you are losing weight, but are you really losing the right kind? Autumn Bates (@autumbates) is a Clinical Nutritionist with a Master's in Nutrition Human Performance. She is also a social media influencer with hundreds of thousands of followers, known for revealing tips on healthy eating, weight loss, and intermittent fasting. In a recent social media post, Autumn revealed “the seven clear signs that you're probably burning muscle and not body fat.”


It’s Important to Lose Body Fat, Not Muscle Mass

“When looking to achieve a weight loss goal, we should always be focused on losing body fat while not losing any or very little muscle mass. When we lose muscle, it results in a slower metabolism and becoming more carb-sensitive, making it a lot easier to regain the weight that we just lost. Not to mention, it just makes us less metabolically healthy,” Autumn says in the video.

There Are 7 “Clear Signs”

“It's super important you know the signs of when you're actually losing muscle so that you can shift gears and make changes asap. So I'm going to share these seven clear signs that you're losing muscle and not fat,” Autumn continues.

Sign 1: You Are Gaining Body Fat

The first sign is that you're gaining body fat. “Now, it is actually possible to lose weight while still gaining body fat so that the scale could be going down, but you could actually be gaining body fat. That's why it's really important actually to measure the right thing,” Autumn says. “I never recommend just using the scale.”

Use the Right Measurements, Like InBody

“You want to use measurements that actually track body fat as well as muscle mass. My favorite option is the InBody. It actually breaks down body fat and muscle mass in pounds as well as percentages. So you can actually see where that weight loss or weight gain is coming from because if you're gaining weight, but if it's all from muscle, that's actually a good thing,” Autumn says.

If You Are Losing Muscle While Gaining Fat, Your Metabolism Is Slowing Down

“The body's going to be stronger. You're going to have a healthier metabolism, and overall, you're actually making progress toward body recomposition. But if you're losing muscle while gaining body fat is actually making it so the metabolism is slower, you're in a less healthy metabolic state, and you're much more likely to gain back the weight that you lost,” Autumn points out.

You Can Also Use a Tape Measure

“You could also use a tape measure, which is a better form of measurement than just a typical scale,” she says. “The InBody can often be found at a gym, or sometimes you can find at a local health food store.”

Sign 2: You Are Losing Muscle Mass

“The second is that you're losing muscle mass,” Autumn continues. “This is what happens when you simply just eat less without actually paying attention to the right types of foods to help hold onto muscle mass. So if you're using the typical eat less, move, more strategy of just calorie restriction and doing a lot of cardio or just a lot of movement in general, this is the common outcome.”

This Happens When You Drop Your Calories, and You Don’t Exercise

“Let's say you're focused on just counting calories, reducing calories, and you drop down to 1600 calories. You start to lose weight on the scale, and so you think you're making progress, but then suddenly, you hit a plateau. So you think, okay, I need just to eat a little bit less. So you drop your calories by another 200. You break through that plateau, and you start to lose weight again, just on the scale. Then you plateau again, and you can see how this process repeats itself. So, in order to continue seeing results, you have to keep eating less and less and less, but if you're actually keeping track of the right measurements, you would see that that weight loss was coming from muscle and not body fat, or at least largely from muscle, which is why you had to keep eating less and less and less in order to achieve or maintain those results,” Autumn says.

Muscle Mass Prevents This From Happening

When we have more muscle mass, it actually gives us a lot more flexibility with the types of foods we can be eating to help support our goals or even maintain our goals, and it helps to prevent this issue of having to eat less and less and less in order to achieve those goals.

Sign 3: You’re Feeling Exhausted After Working Out

The third sign is that you're feeling exhausted after a workout. “This is actually a big sign of overtraining, and one of the results of overtraining is actually losing muscle mass,” Autumn says.

This Happens From Overtraining

“Good high-quality training that's well structured should make you feel more energized for the day and not totally wiped out. When you're in a state of overtraining, it's really common to either go into the workout feeling burnout or to come out of the workout feeling burnout, whichever it is. You shouldn't be feeling excessively burnt out after the workout,” Autumn says.

A Lot of People Don’t Know They Are Overtraining

“What's tricky about this one is a lot of people don't think they fall into this category because maybe they're not working out every single day, and so they assume that there's no way they could be overtraining. But a lot of people actually fall into this trap of overtraining because they don't consider the other stressors in their life over training results because we don't have enough time to recover from stressors. Typically, we would just think of the stressor coming from exercise, but it can come from other stressors as well. Like for example, if you stand a lot at work, that is a big stressor on the body, or if you're eating a really poor diet, that is also a stressor on the body, or if you have just a lot of mental or emotional stress, again, another stressor on the body,” says Autumn.

Make Sure to Give Your Body Rest and Repair

“So if you're not getting adequate rest and repair from your workouts while also accounting for the other stressors in your body, whether it be physical or mental, this can also lead to a state of overtraining. And the horrible irony of it is that from the state of overtraining, you start to see the reverse of what you're actually trying to achieve. You start to see muscle being lost as well as body fat increasing. So a lot of people try to overcorrect the wrong direction and add in more workouts, which is actually just making the problem worse,” Autumn says.

Sign 4: You Are Feeling Weaker

The fourth sign is that you're feeling weaker. “This really goes along with the overtraining. If you find that with your workouts you can no longer do the same intensity or you're not progressing with your workouts, but instead maybe you're actually regressing, then you're probably losing muscle mass,” Autumn says.

“So if maybe in the past you're able to use 15-pound dumbbells, but now you can only use like 12 or 10-pound dumbbells, and that is a huge red flag, you should be getting progressively stronger when you're actually maintaining or even increasing muscle mass a bit and not getting weaker,” she explains.

Sign 5: You Aren’t Sleeping Well

“The fifth is you're getting poor sleep, and specifically, you're getting poor sleep all of a sudden. Like if you've always had poor sleep, there could be other issues going on, like you don't have a good bedtime routine or maybe some nutrient deficiencies,” Autumn says.

If You Aren’t Eating Enough, You Could Be Having Cortisol Spikes and That Can Disrupt Sleep Hormones

“But if suddenly, especially if you are on some type of body recomposition journey, you're noticing that you're not getting great sleep or you're waking up throughout the night, this is also another huge red flag because when you're not eating enough to help support body recomposition and therefore could be losing muscle mass, this can result in cortisol spikes throughout the day,” Autumn says. “That can disrupt our sleep hormone melatonin, which makes it much more likely that you're going to have either restless sleep or wake up often throughout the night. If, instead, you're getting deep, high-quality sleep every single night, then this is a good sign that you probably are on the right track.”

Sign 6: You Are Feeling Cold All the Time

The sixth sign is that you're feeling cold all the time, “especially again, if this is a sudden change,” Autumn says. “When we aren't eating enough to support our body's needs during body recomposition, this can lead to the body having difficulties with regulating internal temperatures, plus having muscle mass actually helps to keep us warm. It's a big portion of actually regulating our body temperature. So if you're losing muscle mass, it's getting harder for the body to actually maintain a consistent body temperature and therefore could result in you feeling colder more often, especially when other people aren't feeling very cold.”

Sign 7: You Are Losing Motivation

“The seventh clear sign is that you're just losing motivation in general or you have low energy levels. We need proper fuel and a well-functioning metabolism in order to have good energy levels and feel good throughout the day,” Autumn says.

A Slowing Metabolism Results in Lower Energy Levels

“On the flip side, a slowing metabolism as a result of losing muscle mass can result in lower energy levels or feeling sluggish or unmotivated again, especially if this is a sudden change. If usually you're somebody who's highly energized, highly motivated, and suddenly you're just feeling really sluggish and not feeling motivated for work or your workouts or things that usually you would be motivated for, then this is a very big red flag that you need to take note of,” Autumn concludes.

Are you on Ozempic or another GLP-1 and want to lose weight faster? “WARNING: Scrolling past the 7 W’s is a GLP-1 Mistake!” Aliza Olive, MD, a weight loss expert who co-founded GLP1Enhanced to help people on their weight loss journeys, writes in a new social media post. “You know that feeling when you’re doing all the things… but the scale’s moving slower than a sloth on NyQuil? Ever feel like you’re missing the secret sauce? Like, what’s the ONE thing keeping the scale from budging? So, you start searching for the one missing piece—maybe a secret supplement or that one viral hack… Except, real results don’t come from magic. The real results, that will last a lifetime, come from mastering The 7 W’s,” she claims. Here they are:

Weights

Weights, aka strength training, is a great way to lose weight faster on Ozempic. “Lift at least 2x per week. Muscle = faster metabolism = easier fat loss,” says Dr. Olive. According to the Mayo Clinic, strength and weight training help reduce body fat, preserve and increase lean muscle mass, and burn calories more efficiently. Strength training may also help you:

  • Develop strong bones
  • Manage your weight
  • Enhance your quality of life
  • Manage chronic conditions
  • Sharpen your thinking skills.

Whole Foods

Designing your diet around whole foods is also helpful. “Protein, fiber, and nutrients first (especially on GLP-1s)… but still room for the foods you love. Balance wins every time,” she writes.

Water

Water and hydration are also essential. “Helps keep things… moving and keeps fake hunger at bay,” Dr. Olive explains. According to the Mayo Clinic, hydration is essential for various reasons. Water helps eliminate waste through urination, perspiration, and bowel movements, keeps your temperature regular, lubricates and cushions joints, and helps protect sensitive tissues.

Walking

Dr. Olive also recommends walking 8- 10k steps daily. It helps with “digestion support + calorie burn without exhausting yourself,” she says. A 2018 study published in Obesity found a link between walking 10,000 steps a day and weight loss and weight management. Other studies published by the Journal of the American Medical Association (JAMA) in JAMA Neurology and in JAMA Internal Medicine also linked walking 10,000 steps a day to less dementia and less cardiovascular disease overall, with less heart disease, less heart failure, and fewer strokes.

Wake Up

She also recommends waking up at a reasonable time. “Stop snoozing. The longer you lay there, the more excuses creep in. Just get up,” she says.

Wins

She also recommends focusing on wins. “Start your day with one small win (like water before coffee) and ride that momentum,” she says.

Weekends

And, finally, don’t neglect yourself on weekends. “Not every weekend is special. If they all were, none of them would be. Find ways to enjoy yourself without feeling like Monday is a reset,” she says.

Bottom Line

Weight management medications like GLP-1 receptor agonists have transformed treatment options for many struggling with obesity, but they come with significant costs and potential pitfalls. Dr. Jennifer McCann, a board-certified OB/GYN and Obesity Medicine specialist, warns that simply taking these medications without proper guidance can lead to disappointing results. "As a provider, I'm frustrated because there are a lot of providers prescribing this medicine without any counseling about lifestyle changes with diet and exercise," says Dr. McCann. Understanding the right approach to these medications could save you thousands of dollars and prevent the frustrating weight regain cycle that many experience.

Muscle loss undermines your success

The weight you lose on GLP medications might come back with a vengeance if you're not careful about how you lose it. "If you're just starving yourself, you're gonna be losing your lean body mass and you're gonna gain the weight back and maybe even more," Dr. McCann cautions in her post. The reason is simple but often overlooked – muscle burns calories continuously throughout the day, and when you lose muscle instead of fat, your metabolism slows down. This metabolic downshift makes maintaining weight loss nearly impossible for many patients, according to Dr. McCann.

Protein intake becomes critical

When appetite suppression kicks in, many patients struggle with getting adequate nutrition. Dr. McCann emphasizes that protein should be your top priority. "If you don't feel like eating on these medications, then you need to make sure you at least take in two things during the day," she advises. Those two non-negotiables are protein and water. Your muscles need protein to maintain their mass during weight loss, and without adequate intake, your body will break down muscle tissue for energy – exactly what you don't want during weight management.

Quality matters for protein sources

Not all protein sources provide the same benefits during GLP-1 treatment. "I have always, for over a decade, recommended this Cornerstone meal replacement," says Dr. McCann. She explains that high-quality protein supplements with added vitamins and minerals can help ensure you're getting essential nutrients even when your appetite is significantly reduced. Two protein-rich meal replacements daily can provide the foundation your body needs while the medication works to control hunger and blood sugar levels.

Exercise preserves muscle function

The second pillar of successful weight management on GLP medications is regular physical activity. "Resistance training is great. It helps build your muscle," Dr. McCann notes. You don't need to become a gym enthusiast overnight – even modest amounts of exercise make a difference. Dr. McCann suggests starting with just 15-20 minutes of activity and gradually increasing duration and intensity. This approach helps preserve muscle mass while the medication helps control appetite.

Compound medications are disappearing

If you've been using compounded versions of GLP medications, significant changes are coming. "The compounded GLPs are gone," Dr. McCann states. She explains that tirzepatide (the active ingredient in Zepbound and Mounjaro) has been removed from the FDA shortage list, meaning compounding pharmacies can no longer legally produce it. Semaglutide (found in Ozempic and Wegovy) compounds will soon follow the same path, leaving many patients wondering about their options.

Manufacturer price drops offer relief

Despite the end of compounded options, there's encouraging news for patients. "Don't panic. The companies have actually lowered their cash price, and this is great news for patients," Dr. McCann reassures. Brand-name manufacturers have introduced more affordable options in response to market demands and increased production capacity. These price reductions make the FDA-approved versions more accessible to patients who were previously relying on compounded alternatives.

Tirzepatide becomes more affordable

For patients preferring tirzepatide (Zepbound/Mounjaro), Eli Lilly has created a more budget-friendly option. "Instead of having it in the auto-injectors, they are sending it in vials, just like the compounded pharmacies did," Dr. McCann explains in another post. This shift in delivery method allows for significant cost savings. According to Dr. McCann, patients can now get the 10mg dose for approximately $500 per month compared to $1,200-$1,500 for the auto-injector version when paying cash.

Getting the discounted version requires specific steps. "Any prescriber should be able to send this from their EHR. They just have to look for the Eli Lilly pharmacy in their e-prescribe," says Dr. McCann. She notes that the 5mg, 7.5mg, and 10mg doses are all available at the $500 cash price. There's also an option for patients with insurance that doesn't cover the medication, priced around $650. These vials require self-injection rather than using the auto-injector device.

Special handling requirements

These medications require proper storage to maintain effectiveness. "You do have a shipping cost in there. It does have to be shipped on ice because it needs to be refrigerated," Dr. McCann points out. This refrigeration requirement is standard for all GLP-1 medications, whether in vial or auto-injector form. The shipping costs add a small premium to the base price but still represent significant savings compared to previous options.

Success with GLP medications requires a comprehensive approach. "Protein, exercise, keep your muscle so you at least have a chance of keeping the weight off," summarizes Dr. McCann. While the medications provide powerful appetite control and metabolic benefits, they work best as part of a complete strategy. By focusing on preserving muscle mass through adequate protein intake and regular exercise, patients maximize their chances of maintaining weight loss long-term, even as medication options and pricing continue to evolve.

Finding truly carb-free foods can feel like searching for a needle in a haystack. Kait Malthaner, a certified health and nutrition coach specialising in blood sugar control and insulin resistance (aka Health Coach Kait), cuts through the confusion as a certified health and nutrition coach specializing in blood sugar control and insulin resistance. Kait is offering genuine guidance without the misleading information that plagues many nutrition resources. Discover her list of zero-carb and low-carb foods that will transform your keto or low-carb lifestyle today.

Beef

As Kait explains in her video, "All types of meat contain zero carbohydrates." Beef tops the list as an excellent protein source with absolutely no carbs. According to Mayo Clinic, beef provides essential nutrients like iron, zinc, and vitamin B12, crucial for energy production and immune function. Kait warns to "watch out for anything that has been pre-marinated or comes with any sauce. These are usually filled with sugar and will not be zero carb." Choose grass-fed options when possible for higher omega-3 content and better fatty acid profiles.

Chicken makes Kait's list of meats that "contain zero carbohydrates." This versatile protein source is not only carb-free but also lower in saturated fat than red meat. The Harvard T.H. Chan School of Public Health notes that chicken provides essential amino acids needed for muscle repair and growth. From roasting to grilling to air-frying, chicken adapts to countless preparation methods while keeping your carb count at zero, making it a staple for any low-carb meal plan.

Pork

Pork is another meat that Kait confirms "contain(s) zero carbohydrates." This versatile protein provides thiamine (vitamin B1) at levels higher than most other foods, according to the National Institutes of Health. Pork tenderloin is particularly lean, while fattier cuts like bacon can add flavor to low-carb meals. However, Kait cautions, "with bacon, more often than not, there is added sugar as a preservative. Now if there is less than one gram, that's not really worth fussing over, but some brands will have more added, so make sure to check your labels."

Turkey

Duck eggs appear on Kait's list of zero-carb animal products. Larger than chicken eggs, duck eggs provide more protein, fat, and nutrients per egg. According to USDA data, duck eggs contain more omega-3 fatty acids than chicken eggs. Their higher fat content and extra-large, rich yolks make them particularly valuable for baking on a keto diet, where they can provide stability and richness without the need for carb-heavy ingredients. The minimal carb content makes them suitable for even the strictest low-carb approaches.

Fish Eggs (Roe)

Kait lists "Butter, ghee, beef tallow, coconut oil, avocado oil, olive oil, MCT oil, flaxseed oil, cod liver oil, palm oil, duck fat, chicken fat, and bacon grease" as zero-carb fats and oils. Butter contains butyrate, a short-chain fatty acid that may support gut health, according to research published in the World Journal of Gastroenterology. The Cleveland Clinic notes that butter also provides fat-soluble vitamins A, D, E, and K2, particularly when sourced from grass-fed cows. With no carbohydrates, butter adds richness and flavor to vegetables and proteins on a ketogenic diet.

Ghee

Beef tallow appears on Kait's list of zero-carb fats and oils. This traditional cooking fat provides a stable option for high-heat cooking due to its high smoke point and predominance of saturated fats, which resist oxidation. Research from the USDA indicates that tallow from grass-fed cattle contains conjugated linoleic acid (CLA), which may have anti-inflammatory properties. With absolutely no carbohydrates and a neutral flavor that won't overpower your food, beef tallow makes an excellent choice for frying or roasting on a ketogenic diet.

Coconut Oil

Coconut oil is included in Kait's zero-carb fats and oils list. This tropical oil contains medium-chain triglycerides (MCTs) that are metabolized differently than longer-chain fats. According to the Harvard T.H. Chan School of Public Health, MCTs go directly to the liver where they can be converted to ketones, potentially supporting ketosis. The mild coconut flavor works well in both sweet and savory dishes, while the complete absence of carbohydrates makes it suitable for even the strictest ketogenic approach.

Avocado oil appears on Kait's list of zero-carb fats and oils. This heart-healthy oil is high in monounsaturated fats, particularly oleic acid, which research published in the American Journal of Clinical Nutrition suggests may help reduce inflammation. With one of the highest smoke points of any cooking oil (about 520°F), avocado oil is ideal for high-heat cooking methods. Mayo Clinic notes that it also provides vitamin E, an antioxidant that supports skin and immune health. With zero carbs, it's perfect for ketogenic cooking.

Mayonnaise

Kait explains that "sauces will vary greatly depending on the brand. Most generic brands have added sugar and other ingredients you want to stay away from, but if you can find the following sauces with no added sugar from brands such as Primal Kitchen and Undivided Food Co., they will probably be less than one gram total carbs per serve." She includes mayonnaise on this list. Made primarily from eggs and oil, traditional mayonnaise contains minimal carbohydrates. Look for versions made with healthy oils like avocado oil rather than inflammatory seed oils for optimal nutrition on a ketogenic diet.

Sour Cream

Sour cream appears on Kait's list of potentially zero-carb sauces. This fermented dairy product provides probiotics that support gut health, according to research published in the Journal of Dairy Science. While commercial varieties may contain stabilizers that add trace carbs, most sour cream contains less than 1g carbohydrate per serving, making it practically zero-carb. The Cleveland Clinic notes that fermented dairy products like sour cream may be easier to digest than fresh dairy for those with mild lactose sensitivity, making it a versatile condiment for your low-carb lifestyle.

Bok Choy

Kait explains, "It is impossible for any vegetable, or fruit for that matter, to truly be zero carb. However, the following vegetables have less than one gram total carbs per serve." She includes bok choy on this list. This Asian vegetable provides substantial vitamin K, which supports bone health and proper blood clotting, according to the National Institutes of Health. Bok choy also offers antioxidant compounds while keeping carbs minimal, making it an excellent addition to stir-fries or as a side dish on a ketogenic diet.

Arugula

While often dismissed as nutritionally empty, iceberg lettuce actually provides hydration, fiber, and small amounts of vitamins A and K, according to the USDA. Its high water content (96%) and crisp texture make it perfect for lettuce wraps as bread alternatives on a ketogenic diet. With virtually no carbohydrate impact, iceberg lettuce offers volume and crunch to meals without affecting blood sugar or ketosis.

When discussing vegetables with slightly higher but still low carb counts, Kait includes "Asparagus, broccoli, cabbage, cauliflower, celery, cucumber, eggplant, green bell pepper, mushrooms, and zucchini" as having under five grams of total carbohydrates. Asparagus provides inulin, a prebiotic fiber that supports gut health, according to research published in the British Journal of Nutrition. The Cleveland Clinic notes that asparagus also contains asparagine, a compound that acts as a natural diuretic, potentially helping reduce water retention. With low carb impact, asparagus makes an elegant side dish for keto meals.

In the fruit category, Kait lists "Olives and coconut flakes" as containing less than five grams of total carbohydrates. These savory fruits provide heart-healthy monounsaturated fats, primarily oleic acid. According to research published in the journal Nutrients, olives contain polyphenols that may have anti-inflammatory and antioxidant effects. Mayo Clinic highlights that the Mediterranean diet, which features olives prominently, is associated with heart health benefits. With minimal carbs and maximum flavor, olives make perfect keto-friendly snacks or recipe ingredients.

Kait lists "Macadamia nuts, almonds, Brazil nuts, hazelnuts, hemp seeds, walnuts, sesame seeds, pecans, peanuts, chia seeds" among nuts and seeds with less than five grams of total carbs. Macadamias have the highest fat content of any nut, with over 75% coming from monounsaturated fats. According to the Journal of Nutrition, their favorable omega-3 to omega-6 ratio may support cardiovascular health. With only about 4 grams of carbs per ounce and substantial manganese content, macadamias offer luxurious texture and flavor for keto snacking or recipes.

Almonds appear on Kait's list of nuts with less than five grams of total carbs. These versatile nuts provide vitamin E, magnesium, and fiber while keeping carbs relatively low. According to research published in the Journal of the American Heart Association, regular almond consumption may help improve cholesterol profiles. Harvard Health notes that almonds provide L-arginine, an amino acid that supports healthy blood vessel function. With approximately 3g net carbs per ounce, almonds offer nutrition and versatility while fitting into ketogenic macronutrient targets.

Cottage Cheese

When discussing dairy beyond zero-carb options, Kait mentions "Cottage cheese, ricotta, and heavy cream" as having slightly higher carbs but still suitable for low-carb diets. Cottage cheese provides casein protein, which digests slowly and may support muscle maintenance during overnight fasting, according to research in the British Journal of Nutrition. The Cleveland Clinic highlights cottage cheese as a good source of selenium, which supports thyroid function. With approximately 3-4g carbs per half-cup, cottage cheese can fit into even strict ketogenic diets when portioned appropriately.
