20 Signs Your Body Is in Fat-Burning Mode

An expert outlines all the things to look out for.

You are eating less and exercising more. But how do you know that your body is actually burning fat? According to Risa Sheppard, Master Pilates trainer and creator of The Sheppard Method, there are lots of signs your body is in fat-burning mode. Some of them are obvious, while others might surprise you. Here are 20 signs your body is in fat-burning mode.


Your Pants Are Looser

If your pants are feeling looser is a key sign your workout is working. “You may be thinking, ‘Duh. My 6-year-old nephew could have told me that,’ but it’s a good sign for a reason! It can be easy to lose track of the progress we’ve made when we look in the mirror, but inches don’t lie. Keep the size in mind you want to be and keep picturing yourself fitting into it,” Sheppard says.

The Sleeves on Your Blouse Are Fitting Looser

Another sign is that the sleeves on your blouse fit looser. “Sometimes people think only about getting a flatter tummy, but exercise helps every part of your body, and progress can show up differently on different muscle groups. Do T-shirts fit a little differently? Noticing when you’re crushing it in the business world that you need to push the sleeves up on your blouse a little more often? You’re on your way to Linda Hamilton in her Terminator days (or at least towards Sigourney Weaver in Alien),” she says.

Cognitive Improvements

Cognitive improvements are also a sign. “Feeling sharper and more able to multi-task? The more you take care of your body, the more your body can take care of your brain. Goodbye, morning fog!” Sheppard says.

Improved Memory

Is your memory getting better? “Your memory for simple tasks becomes easier, and information comes forth more readily. Juggle your workout schedule, your office stresses, and your sister’s needlessly complicated Starbucks order (including the half-calf and extra caramel drizzle),” she says.

Your Brain and Nervous System Are Better and More Positive

Another sign? “Your brain and nervous system are taking in better and more positive information,” says Sheppard. “You find yourself in a better mood because you are accomplishing something positive. You are looking and feeling better, and you only want to swear a LITTLE when someone cuts you off in traffic.”

You Feel Better About Yourself

You will also start feeling better about yourself, she says. “Adding on to the previous item, when your outlook on the outside world improves, so does your outlook on yourself. You feel better not just because you look better, but because you’re taking care of yourself and making healthier choices to allow you to live life to the fullest,” Risa says.

Increased Vitality

Increased vitality is another bonus. “Carrying less weight helps you feel more energetic. You can do things you have not done before (although you may end up slightly regretting that you’ve become your family’s go-to for moving heavy objects),” she says.

Reduced Cravings

“As your health journey continues, you’ll find you crave junk less,” says Sheppard. “Your body gets used to feeling good, and you’ll notice the difference that bucket of popcorn does on how you feel both mentally and physically (although sometimes you just need a treat, and that’s okay!)”

You Have More Restful Sleep

If you have more restful sleep, it could be a sign you are burning fat. “Tiring yourself out at the gym makes it easier for you to catch those Zs that you’ve been sorely missing,” she says.

You’re Not Hungry All the Time

Another sign your diet is working? You’re not hungry all the time. “Although this seems counterintuitive when you exercise, your body produces hormones like GLP-1, which can help you have a better sense of how hungry you actually are,” says Sheppard.

You’re Noticing Some Muscle Definition

You will also start noticing some muscle definition. “Another one you may want to say “duh” to – but if the number on the scale isn’t going down, it can be easy to get into your head. Remember that your lbs alone don’t dictate your health – look to your muscles to remind yourself you’re making progress,” she says.

Chronic Pain Improves

Also, you might notice chronic pain improving. “Exercise can help reduce soreness, swelling, and inflammation. Pilates in particular, can help you to work through injuries,” she says.

Blood Pressure Decreases

Your blood pressure decreasing is another sign. “Isn’t it a relief when you can just measure progress with a number? If only all the other answers were so simple to see,” Sheppard says.

Your Stomach Is Flatter

Another surefire sign you are losing weight? “Your stomach is flatter,” Sheppard says.

You Are Slightly Out of Breath But Can Maintain a Conversation

Are you able to talk when you are exerting energy? “If you’re slightly out of breath but you can maintain a conversation, you’re probably in a fat–burning mode,” says Sheppard.

Your Face Things Out

“Your face and neck will appear thinner when you are losing weight,” says Sheppard. “#Facegains – they’re trending for a reason!”

You Can Run and Jump

Another fun way you can tell if you are burning fat? “You can triumph over your children in a game of Double-Dutch,” she says. “Running or jumping rope are the best weight loss exercises for burning fat. Join the neighborhood competition. So what if you competed against a bunch of 6-year-olds? Six months ago, you couldn’t even chase after them at the grocery store without getting out of breath.”

You’re Breathing Deeper

Are you breathing deeper? “Weight training has a prolonged calorie-burning effect. You need a workout such as weight training that makes your body require more oxygen afterward to recover and repair muscles. As you burn fat and get healthier, you’ll find you’re inhaling more deeply not just during and right after workouts, but in your day-to-day,” Sheppard says.

You Are Consuming More Protein

“While the number of calories burned is important, other factors are in place. For instance, cutting calories in your diet and maintaining a healthy organic diet with lots of protein help maintain a weight loss regime – but that also gets easier when you have a clearer mind,” says Risa.

You Are Enjoying Your Workout

A beautiful girl and her well-built boyfriend are greeting each other with a high-five. They are happy to see each othr in the gym. Young people are ready to start their workout.Shutterstock

“Last but most important- you’re enjoying your workout!” says Sheppard.

With more strength and conditioning comes the ability to work out without feeling like you might have a heart attack. Help yourself reach that point and maintain it by finding out what form of physical activity makes you feel your best and what you enjoy the most.

Standing in front of the mirror, scrutinizing every inch for signs of progress after weeks of dieting? You're not alone. While the scale might be your go-to measure of success, it doesn't tell the whole story of fat loss. As a Sports Scientist and former international athlete, Ivana Chapman has helped thousands transform their bodies through science-based approaches. Drawing from her expertise in Sports Science, NSCA certification, and experience as both an international karate athlete and Canadian National Natural Bikini Competitor, she reveals the hidden signs that prove your body is actually burning fat. Read on to discover the six definitive indicators that show your weight loss plan is working.

1. Scale Patterns Matter More Than Daily Numbers

The first sign requires looking beyond daily fluctuations. "When we're talking about being in a calorie deficit, we want this to be a fairly long duration to see the right changes," says Ivana in her video post. She emphasizes tracking weight trends over at least three months, noting that normal variations occur due to fluid balance and undigested food. To accurately track progress, she recommends calculating weekly averages rather than focusing on daily numbers.

2. Your Measurements Tell the Truth

"The waist to hip ratio can give you an idea of certain risk factors," Ivana explains, highlighting the importance of regular body measurements. While the scale might not budge, changes in your waist, hips, and other key areas can reveal fat loss. She recommends measuring specific areas based on your goals, whether it's your mid-thigh, biceps, or waist circumference.

3. Your Clothes Fit Differently

One of the most reliable indicators of fat loss is how your clothes fit. "You might not see any change in the scale, but you are getting leaner," Ivana points out. Pay particular attention to your waistband and how shirts fit around your midsection. A looser belt notch or more comfortable fit can signal successful fat loss, even when other metrics haven't changed.

4. Progress Photos Show Visible Changes

"Take some pictures of yourself so you can see where you're at at the beginning," Ivana advises. She recommends capturing front, side, and back views weekly. These visual records often reveal changes that might be hard to notice day-to-day, with notable differences becoming apparent after six weeks of consistent effort.

5. Your Appetite Patterns Shift

A subtle increase in hunger can actually indicate success. "Your body is trying to maintain what we call homeostasis," Ivana explains. When you're in a calorie deficit, your body naturally signals for more food. However, she emphasizes that extreme hunger isn't the goal: "A little bit of hunger here and there is okay, do not go to the extremes where you're ravenous all the time."

6. Your Body Temperature Changes

Some people experience feeling colder, particularly in their extremities, when successfully burning fat. While Ivana notes this isn't universal, it can be one of several indicators that your body is adapting to a calorie deficit.

Maintain a Sustainable Approach

While these signs are important indicators, Ivana emphasizes the importance of a sustainable approach. "Please be patient," she advises, recommending a minimum three-month perspective on progress. She warns against extreme calorie restrictions, noting that severe deficits can lead to health issues including loss of sex drive, hair loss, and hormonal disruptions.

The Right Way to Track Progress

Success comes from monitoring multiple indicators while maintaining a reasonable calorie deficit. "Aim for a sustainable approach that can keep you healthy while achieving your weight loss goals," Ivana recommends. This means ensuring proper nutrition with adequate protein, vegetables, and fruits while creating a modest calorie deficit you can maintain long-term.

So, you are working out and trying to shed fat. How do you know that it is actually working? Los Angeles personal trainerJason Kozma, aka Mr. America and Mr. Muscle Beach, is a champion bodybuilder who trains clients at Santa Monica-based High-Performance Personal Training; he explains that there are a few ways to know. “Signs that indicate you are burning fat during exercise can be subtle and may not show immediate results,” he explains. “However, several physiological indicators suggest that your body is using fat for fuel.”


1. Sustained Energy Levels

The first way to know is if your energy levels are sustained. “When your body shifts to burning fat, energy levels tend to stabilize. Fat is a slower-burning fuel, so if you can maintain energy during moderate-intensity workouts (like walking or steady-state cardio), it’s a sign your body is using fat as a primary energy source,” says Kozma.

2. Increased Endurance

The second way is that endurance has increased. “Fat is an efficient fuel source for long-duration, low-to-moderate-intensity activities. If you notice improved endurance over time, this is a sign your body is adapting to burning fat,” he says.

3. Improved Recovery Between Workouts

The next sign? Improved recovery between workouts. “Efficient fat burning leads to faster recovery as fat metabolism promotes better oxygen utilization. If you find yourself recovering more quickly after exercise, your body might be efficiently using fat stores,” he explains.

4. Fatigue During High-Intensity Workouts

Are you experiencing fatigue during high-intensity workouts? “At very high intensities, your body primarily uses glycogen (carbohydrate stores). If you experience fatigue as your glycogen stores deplete and transition into a lower, more sustained pace, your body may switch to burning fat. This applies to cardio workouts. Weight training workouts can be less affected by this transition,” Kozma states.

5. Stable Hunger Levels Post-Workout

If your hunger levels stabilize, it could be a fat-burning signal. “Fat oxidation can help stabilize blood sugar levels, preventing extreme hunger post-workout. If your appetite remains relatively stable after workouts, it could indicate that your body is efficiently burning fat,” says Kozma.

6. Gradual Weight Loss or Inch Loss

Gradual weight loss is another sign. “Over time, one of the clearest signs of fat loss is a gradual decrease in body weight or body measurements even if your weight does not decrease as much as expected. If you notice that you’re losing inches or your clothes fit better, it's a good indication of fat loss,” he says.

7. Heart Rate in the Fat-Burning Zone

Exercising in the "fat-burning zone" typically means keeping your heart rate between 60-70% of your maximum. “Using a heart rate monitor (muffin built into cardio machines these days, or easily tracked with a wearable like an Apple Watch or Fitbit) can help you gauge if you're in this zone,” says Kozma.

8. Changes in Body Composition

The last sign is changes in body composition. “If you're noticing a change in how your body looks and feels (less fat, more muscle definition), it's likely that you're burning fat during your workouts, even if the scale doesn't show it immediately,” Kozma says.

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.

You are counting calories and trying to stay in a deficit – but how do you really know if you are succeeding? According to one expert, there are more than a handful of signs your body will give you that you are, in fact, in a calorie deficit. Brittney Blanco is a Macros Nutrition Coach and digital creator who regularly shares her weight loss and stay-fit tricks and tips with her followers. In a new post, she reveals what to look for. “6 signs your body is in a calorie deficit…so keep everything the same,” she writes across the Instagram video.


What Is a Calorie Deficit

“Here’s what it means,” she writes in the post. “A calorie deficit means you’re burning more calories than you consume, which leads to fat loss. Make sure to maintain a balance, fueling your body with nutrient-dense foods to support performance and recovery. When you’re in a deficit, your body turns to stored fat for energy to make up for the difference, which leads to weight loss over time.”

Steady Weight Loss

The first sign is that you are losing weight. “Steady weight loss,” she explains. How much should you be losing? “If you’re consistently losing 0.5-1 pound per week, it’s a clear sign you’re in a calorie deficit,” she writes.

Increased Hunger

Another sign that your body will give you is that it will be feeling a little food deprived. “Increased hunger,” she writes. “Your body might signal for more food as it adapts to consuming fewer calories.”

Improved Muscle Definition

Improved muscle definition is another physical sign your body will give you that it is in calorie deficit. “As fat decreases, you’ll start seeing more muscle tone, especially if you’re strength training,” she writes.

Increased Energy

You would think that if you are in a calorie deficit you would lose energy, but this isn’t the case. “Increased energy,” is the fourth sign, according to Brittney. “As your body adapts to the calorie deficit, you might feel lighter, more energetic, and less sluggish throughout the day,” she says.

Consistent Exercise Performance

The next sign? Consistent exercise performance, she reveals. “If you’re still hitting your workouts with strength and endurance, it’s a good sign your body is handling the deficit well,” she claims.

Improved Sleep and Mood

When working out and dieting, the goal is to burn fat – not muscle. But how do you know if you are actually accomplishing it? In a new YouTube video, Autumn Bates, a Clinical Nutritionist who has a Master's in Nutrition Human Performance reveals the “five signs that you're burning fat and not muscle during your weight loss journey.”


1. You Can’t Rely on a Traditional Scale

“If you're purely relying just on a traditional scale, it's pretty much impossible to actually tell if you're losing body fat or if you're losing muscle mass. And this really matters if you're looking for long-term sustainable results,” Autumn explains.

2. Losing Fat – Not Muscle – Is Beneficial in the Long Run

“Most traditional calorie restricted protocols will result in a significant amount of muscle loss. This muscle loss can then cause a decrease in metabolism as well as a host of other issues for long-term health, like reduced bone density, increased risk of osteoporosis, as well as increased risk of insulin resistance and type two diabetes,” she says, adding “losing muscle mass just makes us more sensitive to carbohydrates, so it makes gaining weight back so much easier.” She explains that using a few tools can help address this issue, allowing you to keep your metabolism revving and so you can reap the “benefits of having muscle mass on our body for long-term health and make it so we can maintain our results for the long run.”

3. First Sign: Your Clothes Are Fitting Differently

The first sign that you're losing body fat and not muscle mass” is that “your clothes are fitting differently,” Autumn says. “Now, you've probably heard the saying that muscle weighs more than fat, and although that's like a little play on words, what it really means is that per volume muscle is going to be a lot more dense. So five pounds of muscle is going to look a lot smaller than five pounds of fat. That's why you'll often see these photos on Instagram or other platforms where you see these people who look really toned, really fit, but they weigh more than you would've expected. That's because they have lower body fat, but they have a lot higher muscle mass. So when you're losing body fat while maintaining or even slightly increasing muscle mass, it can result in your clothes feeling a lot looser. And this is because we're getting rid of body fat that takes up more physical space, but leaving behind the leaner muscle mass, especially for women. You might notice this more so in your pants.”

4. Second Sign: You Are Not As Hungry

“The second sign is that you're not as hungry,” says Autumn. “Burning fat as fuel tends to make us less hungry, especially when you're focused on the types of foods that help us to more efficiently burn fat as fuel, which are those that are rich in protein, fat, and fiber,” she adds, emphasizing that “protein is the most important macronutrient when it comes to actually maintaining muscle mass during a weight loss process. It's really just mandatory to be eating enough protein to actually maintain muscle mass. When you're losing weight and eating enough protein for the body's needs is so satiating, you're just not really hungry. So eating high quality proteins like eggs, Greek yogurt, beef, chicken, pork, tempeh, are great tools for not only helping to keep muscle mass while burning body fat, but also to just not feel hungry during the weight loss process.”

5. Third Sign: Your Measurements Are Decreasing

The third sign that you're burning fat and not muscle “is that the measurements are decreasing even if the scale is not,” says Autumn. “I prefer taking measurements rather than just looking at the scale because it actually gives you an idea of what your body composition is, depending on which form of measurement you're using. It can even tell you specifically how many pounds of body fat you lost or how many pounds of muscle mass you lost or gained. A regular scale can't do that.” You can also measure yourself using an old school tape measure.

6. Fourth Sign: You Are Getting Stronger

“The fourth sign is that you're getting stronger,” she continues. “Assuming that you're actually exercising and using some type of resistance training, which is a necessity to maintain muscle mass during the weight loss process, you should be feeling stronger during your weight loss journey. If you're progressively feeling weaker after every week of workouts, then you're very likely losing muscle mass. If that's the case, it's definitely time to reassess your protein intake, especially to make sure it's actually fitting your body's needs and to make sure that you're getting that protein from high quality complete sources. So if you need a little refresher on that, you can check out my video right up here for the 10 best high quality sources of protein.”

7. Fifth Sign: You See Muscle Definition

The fifth sign? “You start to notice muscle definition,” says Autumn. “Maybe you start to notice that your quad muscles are peaking out or that you're starting to see your abs a little bit. If that's the case, all of these are signs that your body's actually losing body fat, which helps you show muscle definition because muscle definition and toning is really only going to start to become obvious as we decrease body fat percentage, although you can definitely be losing body fat and not noticing muscle mass quite yet. But if you do start to notice muscle definition, then that is one way to determine that you're actually burning body fat.”

8. Take Periodic Progress Pictures

Autumn recommends “taking periodic progress pictures” which “can be helpful for actually seeing this progress,” she says. “I did this for myself as well, because it's hard to notice those changes day after day, but actually seeing pictures of your progress can really help to see those changes”

9. An Expert Agrees That the Scale Is Not a Good Measure of Health

Chris_McMahon2.Christopher Michael/Facebook

Chris McMahon, a nutrition and fitness coach, agrees that you can’t rely on the scale when you are trying to get into shape. “Even if you're working out, you'll see the scale go up and things of that nature because you're retaining water and glycogen, which is an energy form that we can keep in our muscles,” he says.

10. He Also Agrees That Fiber and Protein Intake Are Crucial

Chris_McMahonChristopher Michael/Facebook

He also agrees that your nutrition goals should be eating “plenty of fiber,” as it is “connected to hunger and fullness” and amping up your protein intake. “For most individuals who are trying to lean out, we want to make sure that your protein intake is high, because that will help with hunger and fullness,” says McMahon. “It'll also help with preserving the muscle mass you have. And if you are lifting weights and you are training, it'll help you build muscle and recover. So we want to make sure that's higher.”

💪🔥Body Booster: Try not to rely on the numbers on the scale when you are losing weight. Losing fat – not muscle – is an important goal when it comes to weight loss. Improving muscle mass will help you achieve long term weight loss goals.

No need to drop to the floor for these pushups. Sit on a sturdy chair with armrests, place your hands on the armrests, and keep your shoulders relaxed. Engage your core, then push yourself up slightly off the seat using your arms. Lower yourself back down slowly and repeat. This move works your triceps and shoulders while giving you a break from sitting.

Try for: 8-12 repetitions, 2-3 sets.

2. Desk Pushups

Ready to level up? "Place your hands shoulder-width apart on the edge of your desk. Walk your feet back, shifting your weight onto your toes. Lower your chest toward the desk, then push back up to the starting position," recommends physical therapist and athletic trainer Dr. Eric Moogerfeld, DPT, through Cleveland Clinic. Just make sure your desk is stable enough to support your weight!

Try for: 8-10 repetitions, 2 sets.

3. Chair Squats

Let's get those legs working! "Sit toward the front of a sturdy chair with your knees bent and feet flat on the floor, shoulder-width apart. Rest your hands lightly on the seat or cross them over your chest. Slowly stand up, using your hands as little as possible. Pause, then slowly sit back down without collapsing into the chair," recommends the CDC's STEADI program.

Try for: 10-12 repetitions, 2 sets.

4. Toe Raises

Don't forget about your calves! Cleveland Clinic notes that "your calves help you run, walk, jump, and balance. Calf raises strengthen them." Start by doing these while sitting. As you build strength, try standing behind your chair for support.

Try for: 15-20 repetitions, 2-3 sets.

5. Sidekicks

Finally, strengthen those hips! Stand behind your chair for balance, then lift one leg out to the side while keeping your body upright. Keep the movement controlled (no swinging!), then lower it back down slowly. Repeat with the other leg. This exercise improves both strength and balance.

Try for: 8-10 repetitions per side, 2 sets.

Why These Quick Moves Matter

These five-minute exercise breaks add up to big benefits over time. "If you do that four or five times throughout the day, you've really gathered a great deal of resistance training and body weight exercises spread out throughout your day," explains Johnson. "So it makes it a little more doable if you're not able to get to the gym."

The Long-Term Payoff

Dr. Nathan LeBrasseur, Director of the Robert and Arlene Kogod Center on Aging at Mayo Clinic, stresses that consistency is key: "Just adding 30 minutes of activity daily can be beneficial. It may have benefits for muscle strength, bone health, or even cognitive health and function." Try setting calendar reminders every 90 minutes as your cue to stand up and move—even the most dedicated workers can spare two minutes for their health.

Small Habits, Big Results

"Many studies show that exercise can mitigate virtually every one of the effects of aging, including loss of lean muscle mass and increased fall risk. These little things really work if done regularly—you're going to reap magical benefits," says professor of physical medicine and rehabilitationDr. Edward Laskowski. Consider pairing these exercises with other daily habits—like doing chair pushups while waiting for your computer to boot up or toe raises during conference calls—to make them second nature.

So next time you feel that afternoon slump coming on, try a few desk exercises instead of reaching for another coffee. Your body will thank you today, and your future self will thank you even more.

Are you trying to lose weight? Many health experts maintain that starting the day with a fat-burning beverage is the key to revving your metabolism. However, not all weight loss drinks and products claiming to be an instant fix are actually effective. In fact, many of the best morning weight-loss drinks are much more natural and less processed than you would think. Here are 6 morning drinks that can help you burn belly fat.

Water

The most important drink for fat loss is water. Not only will staying hydrated keep your body functioning and metabolism working properly, but it can also ward off hunger. One eight-week study of 50 girls with excess weight found that those who drank about two cups of water half an hour before breakfast, lunch, and dinner without any additional dietary changes, successfully lost weight and decreased BMI. Another study in Journal of Clinical Endocrinology & Metabolism found a link between drinking about two cups of 71°F water and a 30% average increase in the metabolic rates of 14 healthy adults.

Coffee

There are lots of studies that found a link between drinking coffee and weight loss. One found that women who drink higher amounts of coffee had a lower body fat percentage compared to those who drink less coffee. Another found that those who consume caffeine 30 minutes to 4 hours before mealtime eat less. It’s important to note that most research involves black coffee – not coffee drowned in cream and sugar or other high-calorie sweetened coffee drinks.

Protein Shake

Starting your day with a protein shake is a great way to burn belly fat. Clinical trials have found that consuming more protein than the recommended dietary allowance not only reduces body weight (BW) but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets. Most experts recommend at least 30 grams of protein per meal.

Green Tea

Numerous studies have found that there are many benefits to drinking green tea, including boosting your immune system, fighting inflammation, and even warding off cancer and heart disease. The NCCIH adds that it can help stimulate weight loss,” in addition to having “possible protective effects” against heart disease and cancer. How does it do this? Per an animal study, the catechins (polyphenols) in green tea may help trigger thermogenesis and fat oxidation, which helps decrease appetite and speed calorie burning.

ACV

Lots of people swear by taking a shot of ACV in the morning, and one of the reasons is fat loss. Limited research suggests that ACV may help reduce high cholesterol and regulate blood glucose levels.

Chia Seed Water

Chia seed water regularly goes viral, with users claiming that the fiber-packed drink helps them lose weight. Just combine one tablespoon of chia seeds with a glass of water (optional: add lime) and drink 30 minutes before meals,” TikTok user @happyandhealthyolivia says in a viral video. Just one ounce (about two tablespoons) of the tiny black seeds boasts 4.7g protein, 10 g fiber (an excellent source), and 9 g fat (almost exclusively the good kind), per the U.S. Department of Agriculture.

As a holistic nutritionist and founder of Joy Villa Fitness, I see it all the time—women (and men) trying their best to eat healthy, only to be tricked by sneaky marketing labels and processed products pretending to be good for you. Just because it says “natural,” “low-fat,” or “plant-based” doesn’t mean it’s nourishing your body. Here are 7 popular “health” foods I never eat—and what I recommend instead:

1. Flavored Yogurt

Why I skip it: Packed with added sugars, artificial flavors, and preservatives. Some have as much sugar as a donut!

What I eat instead: Plain, full-fat Greek yogurt or coconut yogurt with a handful of berries and cinnamon.

2. Granola Bars

Why I skip it: Most are glorified candy bars, full of sugar, seed oils, and additives.

What I eat instead: Homemade energy bites with nuts, seeds, protein powder, and a touch of honey—or just a handful of almonds and a boiled egg for real fuel.

3. Store-Bought Veggie Chips

Why I skip it: Fried in inflammatory oils and stripped of nutrients.

What I eat instead: Baked kale chips with sea salt and avocado oil—or crunchy cucumber and bell pepper slices with hummus.

4. Diet Soda or “Zero-Calorie” Drinks

Why I skip it: Artificial sweeteners disrupt your gut, trigger cravings, and are linked to long-term health risks.

What I drink instead: Sparkling mineral water with lemon or stevia-sweetened herbal iced teas.

5. Processed Plant-Based Meats

Why I skip it: Highly processed, loaded with GMO soy, chemicals, and fake flavors.

What I eat instead: Grilled tempeh, wild-caught fish, or grass-fed beef—REAL food from nature.

6. Low-Fat or Fat-Free Anything

Why I skip it: Stripping out fat often means adding sugar or chemicals to make it taste good. Your body needs healthy fats for hormones, brain health, and metabolism.

What I eat instead: Full-fat, real foods like avocado, olive oil, grass-fed butter, and fatty fish.

7. Pre-Made Smoothies or Juices from Chains

Why I skip it: Most are sugar bombs in disguise—some with over 50 grams of sugar in one drink.

What I drink instead: Homemade smoothies with protein powder, greens, berries, and unsweetened almond milk. You control what goes in your body!
