Struggling with low energy, mood swings, or constant hunger? Your fat intake might be the missing piece. Understanding the right types and amounts of dietary fat can transform your health journey from frustrating to fulfilling. In this guide, certified nutrition health coach and metabolism specialistLillie Kane, who has helped thousands optimize their nutrition through her popular YouTube channel, shares essential insights about dietary fats and how to optimize them for better health.


Why Your Body Needs Good Fats

"Our bodies are made up of cells, and our cells are made up of fat," Lillie explains in her post. "If we consume poor quality fats, our cells reflect this and it impacts our health negatively." She emphasizes avoiding man-made, refined fats and laboratory-processed oils, which have been linked to cell damage and heart disease.

Best Sources of Healthy Fats

Lillie recommends focusing on real, whole-food sources of fat: "Eggs, steak, milk, yogurt, butter, ghee, tallow, coconuts, olives, and avocados are excellent sources." For those who tolerate nuts, she suggests macadamia, walnuts, and pistachios. Fatty fish like salmon, sardines, and mackerel provide valuable omega-3s and heart-healthy fats. Next, she explains the significant symptoms of your body's needing more fat.

Low Energy

"Having low energy" is a primary indicator of insufficient fat intake, Lillie warns. Since fats fuel our bodies, inadequate amounts can leave you feeling drained.

Hormonal Imbalances

"For women, having irregular menstrual cycles or even really painful period cramps" are common signs, says Lillie. "For men, this can include low testosterone and libido."

Mental Fog

"If someone's having a hard time focusing or even memory issues, this could be a sign they're low in fat," Lillie explains. The brain requires adequate fat for optimal function.

Dry Eyes

"Fat can help with lubrication," Lillie notes, making dry eyes a clear indicator of potential fat deficiency.

Constipation

According to Lillie, "dietary fat can help move our bowels through our digestive tract," making constipation a common sign of insufficient fat intake.

Persistent Hunger

Lillie identifies "persistent hunger" as a key sign of low fat intake, as fats play a crucial role in satiety.

Temperature Regulation Issue

"If someone's feeling cold all the time and they just can't seem to get warm, this could be a sign someone's low in fat," Lillie shares.

Emotional Imbalances

"Having emotional imbalances or irritability" indicates potential fat deficiency, as Lillie explains that "fats can help us balance our overall hormones and mood."

Understanding Macronutrient Basics

"Think of protein as the structure of a car, while fats and carbs are the gasoline," Lillie explains. Protein builds the body's components, while fats and carbohydrates provide energy. Fat plays a crucial role in brain function and hormone regulation.

The Fat Formula: Finding Your Perfect Balance

Lillie's approach starts with protein: "Begin with one gram of protein per pound of ideal body weight." From there, she recommends balancing fats and carbs to equal or exceed your protein intake in grams.RELATED:20 Superfoods for People Over 50

How Much Fat Do You Really Need?

"Most people should aim for at least 100 grams of fat daily," Lillie advises. The exact amount varies based on individual needs and symptoms. Those experiencing mood issues, menstrual irregularities, or concentration problems might benefit from increasing fat intake.

Practical Tips for Fat Implementation

For optimal fat incorporation, Lillie suggests tracking food intake for one week to understand patterns. High-protein, low-fat foods like chicken breast or shrimp need additional fat sources. She recommends using vegetables as fat vehicles, cooking them in healthy fats like bacon fat or ghee.

Personalizing Your Fat Intake

As an example, Lillie shares her personal metrics: "At 5'2" and 115 pounds, I consume 130-140 grams of protein, 130-140 grams of fat, and 80-100 grams of carbs daily." She emphasizes that these numbers should be adjusted based on individual goals and responses.Remember, optimizing your fat intake isn't about following rigid rules but finding what works best for your body. Pay attention to how you feel and adjust accordingly. Your perfect balance of fats might be different from someone else's, and that's perfectly normal.

Are you experiencing unexplained fatigue, brittle nails, or slow-healing wounds? Your body might be waving red flags about protein deficiency. Dr. Jin W. Sung, a prominent health expert with nearly 500,000 YouTube subscribers, reveals seven critical signs that could indicate you're not getting enough protein. Understanding these signals could be the key to unlocking better health, stronger immunity, and improved overall wellness. Read on to discover if your body is trying to tell you something important.

The Hidden Language of Protein Deficiency: 7 Warning Signs

"Most people don't realize how many different ways their body signals protein deficiency," says Dr. Sung. These seven key signs can help you identify if you're getting enough protein in your diet. Pay attention if you experience any of these symptoms, especially in combination.

Sign #1: Struggling to Build or Maintain Muscle

"Muscle loss or inability to gain muscle despite working out is a major red flag," warns Dr. Sung. If you're hitting the gym regularly but not seeing results, or noticing muscle weakness despite regular activity, your protein intake might be insufficient. For optimal muscle health, Dr. Sung recommends 1.2 to 1.4 grams of protein per kilogram of body weight daily, with athletes needing up to 2 grams per kilogram.

Sign #2: Brittle Hair and Weak Nails

Notice your hair breaking easily or nails becoming increasingly brittle? Dr. Sung explains that these changes often signal protein deficiency, as hair and nails are primarily made of protein. Regular monitoring of your protein intake is crucial for maintaining strong, healthy hair and nails.

Sign #3: Slow-Healing Wounds

"When you get a cut and it doesn't heal well or in the expected time frame, that's a clear sign," Dr. Sung notes. Protein plays a crucial role in tissue repair and wound healing. If small cuts or bruises take longer than usual to heal, your body might need more protein to support its repair processes.

Sign #4: Weakened Immune System

"These people will be more prone to infection or become currently sick," Dr. Sung explains about protein-deficient individuals. If you're catching every cold that comes around or infections seem to linger, your immune system might be struggling due to inadequate protein intake.

Sign #5: Sleep Issues and Mood Changes

Experiencing anxiety, depression, or insomnia? According to Dr. Sung, these could be unexpected signs of protein deficiency. Studies show that protein is essential for producing neurotransmitters that regulate mood and sleep patterns.

Sign #6: Bone Health Concerns

"People don't realize it's not just calcium and minerals in the bone. There's protein amino acids too," Dr. Sung emphasizes. If you're concerned about bone density or have been diagnosed with osteoporosis, increasing your protein intake might be crucial for maintaining bone health.

Sign #7: Constant Hunger and Cravings

While not directly quoted by Dr. Sung, research shows that inadequate protein intake can lead to increased hunger and cravings. Dr. Sung's recommended protein intake of 1.2 to 1.4 grams per kilogram of body weight can help maintain satiety and reduce unnecessary snacking.

Understanding Your Protein Needs

Dr. Sung breaks down the numbers clearly: "A 150-pound person needs at least 81.6 to 95.2 grams of protein per day for optimal health." For those with health challenges, he recommends increasing intake to 1.6 grams per kilogram of body weight, while athletes might need up to 2 grams per kilogram.

How to Check for Protein Deficiency

"Simple tests like CBC with CHE can show you if you have protein deficiencies," explains Dr. Sung. Key markers include BUN (should be 10-16), globulin (2.4-2.8), and hemoglobin levels. If you're experiencing any of the seven signs, consider asking your healthcare provider about these tests.

Solutions for Better Protein Absorption

Dr. Sung emphasizes that it's not just about eating more protein – it's about proper absorption too. "If you have hypochlorhydria or low stomach acid issues, you definitely want to increase hydrochloric acid along with some digestive enzymes to break down your protein appropriately," he advises. Consider protein-rich diets like ketogenic, paleo, or carefully planned vegetarian diets, depending on your specific needs and restrictions.

Protein is the building block of muscle and a major player in the game of losing fat – but are you eating enough of it? In a new social media post, online fitness trainer and coach Alexandra (@alexx.fitt), who lost a whopping 50 pounds via diet and exercise, dives into the topic, revealing “4 signs you’re not eating enough protein.” Are you suffering from any of them?


Fatigue and Weakness

Fatigue and weakness is the first sign, says Alexandra, like if “you don’t feel as strong in the gym or during any physical activity,” she says. “Protein is crucial for muscle growth and repair.”

Brittle Hair, Skin, and Nails

Brittle hair, skin, and nails is another sign, she says. “Insufficient protein intake can lead to weaker nails, thinning hair, and dry skin.”

Constant Sugar and Carb Cravings

Constant sugar/carb cravings is the third sign. “This one hits me like a truck,” she maintains. “If I don’t eat enough protein I will overeat on so much sugar but you won’t be satisfied until you get your protein in,” she claims.

Constant Hunger

Are you constantly hungry? It could be because you aren’t fueling your body with enough protein. “Eating enough protein will keep you fuller for longer and leave you more satisfied,” she claims.

According to clinical trials, 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.

Aim for 20 to 30 Grams Per Meal

How much protein should you aim for? Body Network’s 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, explains that protein needs depend on body size, gender, and of course activity level. “Most people will benefit from at least 20 grams of protein per meal (women) and 30 grams per meal (men). If that isn’t enough for the day, then make up more at snack time,” she says.

Protein Helps with Hunger and Fullness

“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,” Chris McMahon, a nutrition and fitness coach, added to Body Network. “It'll also help preserve your muscle mass. 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.”

Stick to Lean Fats

And, if you are trying to lean out, keep your protein lean, making sure the ratio of fat is lower. “Fat just tends to be a more expensive macronutrient. In one gram of protein, there are four calories. In one gram of fat, there are nine calories. So if you're someone who's used to eating fattier pieces of steak, if you're eating darker meat, then you're going to have higher fat content. So it just comes down to if I eat a leaner source of protein, if I switch to non-fat Greek yogurt, if I switch to 1% cottage cheese, if I'm aware of those things, you're going to be able to increase the amount of it that you're eating without driving up your calories,” explains McMahon.

💪🔥Body Booster: If you want to lose weight and build muscle, make sure to consume 20 to 30 grams of protein per meal, determined by factors such as your gender, activity level, and weight.

Think you're getting enough protein? Many of us don't, and the signs aren't always obvious. In this revealing countdown, we'll explore ten increasingly important signs of protein deficiency, starting with subtle hints and building up to serious warning signals that demand attention.

Dr. Ken Berry, a family physician with over 20 years of clinical experience, brings crucial insights about protein deficiency that could transform your health. As he explains, "There are sources of information out there that will tell you that eating too much protein is bad for you... In fact, nothing could be further from the truth." Join us as we count down these essential warning signs that could help you identify and correct this common deficiency.

Sleep Disruptions – The Surprising Sign

The countdown begins with an unexpected connection. Dr. Berry shares his own surprise at this finding: "When I was doing the research for this video, I did not know that a protein deficiency can lead to insomnia, but it's actually quite well known in the sleep literature," he says in his video post.

Mood Changes

Your protein intake might be affecting your emotional well-being more than you realize. As Dr. Berry notes, "If you're always down in the dumps, you always have a negative mood, this is actually a sign of protein deficiency."

Unusual Cravings and Hunger

Those persistent cravings aren't random. Dr. Berry explains, "Your body's looking for a very short list of nutrients in your diet. It's looking for amino acids that come from protein... If you're not getting enough protein in your diet, then your body is going to increase your hunger and it's going to make you have these weird cravings trying to get the particular amino acid or protein molecule that it's looking for."

Brittle Hair, Nails, and Skin Issues

Physical appearance often reflects internal nutrition. Dr. Berry warns, "If your skin is dry and flaky and very thin, if your nails break very easily or they flake up very easily, if your hair's brittle and breaks, if you're having hair loss for no apparent reason, these are all signs of protein deficiency."

Slow-Healing Wounds

Notice how long it takes for cuts and scrapes to heal? Dr. Berry points out, "If you've been eating low protein for years or decades, then you've gotten used to how long it takes for your wounds to heal, so you may not recognize your wound healing as slow, so maybe ask some friends and relatives how long it takes for a scrape or a cut or an abrasion to heal."

Frequent Infections

Your immune system needs protein to function properly. Dr. Berry explains, "If you have frequent upper respiratory infections or frequent bladder infections or frequent skin infections... Your immune system has to have a lot of protein in order to fight off infections, whether we're talking about bacterial infections or viral infections."

Stunted Growth in Children

For children, protein deficiency can have lasting consequences. "Stunning growth is almost always due, at least in part to a protein deficiency," Dr. Berry emphasizes. "The child just not getting enough protein... if you want your child to grow up to be tall and strong and beautiful and intelligent, they've got to get enough protein in their diet."

Muscle Loss

Muscle health is a crucial indicator. Dr. Berry states, "A very common sign of protein deficiency is muscle loss or the inability to gain muscle. This is very common in the elderly. As they don't eat enough protein, they lose their muscle mass. In some athletes, if they're not eating enough protein, they work out really hard and they don't gain muscle at all."

Decreased Bone Strength

This sign challenges common misconceptions. Dr. Berry explains, "Most people think bones are made of calcium. They're actually made of protein with a calcium atom stuck into the matrix of the protein. Your bones are all protein, and if you're not eating enough protein, your body will not be able to keep your bones strong."

Severe Edema

In advanced cases, protein deficiency can lead to visible swelling. Dr. Berry warns, "If you have a severe terrible protein deficiency, you can actually develop edema or swelling in your ankles and feet. This is kind of an end stage sign when you've been protein deficient for so long that your body's about to give up."

Expert Recommendations: Getting Enough Protein

Dr. Berry recommends focusing on whole food sources: "The best sources for protein that I recommend are meat, fish, eggs, and cheese." He specifically notes, "Never ever do you need a protein shake or a protein bar or a protein powder. Those are usually wind up being carbohydrate shakes in bars and powders."

For optimal intake, he advises "two grams of protein per kilogram of body weight, or if you're in the United States, then one gram of protein per pound of body weight." He emphasizes that this isn't excessive: "Protein's good for your kidneys, protein's good for your bones. Protein is good for every other part of you."


Special attention should be paid to at-risk groups: elderly individuals who might default to simple carbohydrates, women (especially during pregnancy and breastfeeding), and growing children who might prefer snacks over protein-rich foods.

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 man who measures a waist with a tape measureShutterstock

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.

Erin Oprea is showing off her tiny waist – and schooling her followers about the importance of protein. In a new social media post, trainer to country stars Carrie Underwood and Maren Morris, discusses how protein is so crucial to weight loss. “LADIES, sooooo many of you are lacking PROTEIN!!! I hear it daily from you guys. A lot of women are getting 30 to 50 grams per day, that’s TERRIBLE!!! It’s time today to start focusing and you’ll see/feel a world of difference in your body!!!” she wrote in the caption, revealing 9 signs that you are protein deficient.


1. Hungry Quickly After Eating

The first sign you aren’t getting enough protein is that you get hungry shortly after eating. “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,” Chris McMahon, a nutrition and fitness coach, explains to The Body Network.

2. Losing Muscles

If you notice your muscles are dwindling away, it might be because you aren’t getting enough protein, according to Erin. McMahon explains that protein is a fundamental building block for muscles and helps you preserve them. “And if you are lifting weights and you are training, it'll help you build muscle,” he says.

3. Thinning Hair

According to Erin, thinning hair is another sign you aren’t getting enough protein.

4. Always Sore

Are you always sore? Maybe you aren’t getting enough protein, per Erin. McMahon confirms that protein helps you “recover” from your workouts.

5. Anemia

Are you anemic? It could be because of your diet. “Anemia is a condition that develops when your blood produces a lower-than-normal amount of healthy red blood cells,” explains the NIH. One of the ways you can become anemic is through an iron deficiency, and protein can help with that.

6. Brittle Nails

Do your nails keep breaking? Erin mentions that it may be due to lack of protein – and UCLA Health agrees. Along with brittle hair, brittle nails are “often the first sign of deficiency,” they say.

7. Fluid Retention

If you aren’t getting enough protein, your body might be retaining fluids, according to Erin.

8. Fatigue

If you feel tired, you might want to amp up protein, says Erin. UCLA Health also notes that trouble thinking “due to fluctuating blood sugar and protein’s effect on the brain’s neurotransmitters (which regulate mood)” and muscle weakness, “since amino acids are essential for building muscle mass,” are signs of protein deficiency.

9. Getting Sick Often

If you are getting sick a lot, take your protein situation under consideration, says Erin. UCLA Health adds that protein helps boost the immune system.

Are you over 40 and trying to lose weight? Getting in shape can be overwhelming. However, it doesn’t have to be. One personal trainer maintains that all you need to do is master five simple exercises. Caroline Idiens is a fitness influencer and personal trainer with over 25 years of professional experience helping clients achieve their fitness goals. In a new post, she reveals a few key moves to help you shape up. “5 exercises you need to do at 40+ to build strength💪🏻add weights as you progress,” she writes.

Squats

The first exercise? Squats. “Squats are a brilliant compound functional move building lower body strength and engaging the core,” she says. “You can do bodyweight squats or use weights/bands. This exercise works quadriceps, glutes, hamstrings, core.”

Lunges

Next up, another glute buster, lunges, a “functional move,” she explains. “You can do forward, reverse & lateral lunges. This exercise works glutes, hamstrings, quads. Again add weights as needed.”

Push-Ups

Another exercise that offers a lot of bang for its buck? Push-ups, “a brilliant bodyweight exercise that build upper body strength & engage the core. Modify as needed (e.g incline push-ups against the wall or a chair),” she says. “This exercise works your chest, shoulders, triceps, and core.”

Rows

Rows, either with body weight or actual weights, as you progress. “Rows strengthen your back, improve your posture. Great functional move. They work the back muscles as well as engaging the arms & shoulders & core for stability,” she says.

Planks

And last but not least, planks. They are “a great exercise for building upper body & core strength,” she says. “They work your deep core muscles.”

Lift Weights

“Strength training is vital as you age. My passion has always been strength training, and never more so than today,” Caroline previously wrote for Sheer Luxe. “Once we hit 30, our bone density and muscle mass decrease. Strength training plays a significant role in preventing this loss and we can actually build new bone by using weights. This can help reduce the risk of osteoporosis, which women are so susceptible to, especially post-menopause.”

There Are Lots of Benefits

“Moreover, strength training gives you such a feeling of power in everyday life – it’ll help with sleep, anxiety, co-ordination and will also help you manage your weight,” she wrote, adding that it “won’t make you bulky,” despite popular misconception. “It’s a myth that using weights will make you bulky – unless you are using very heavy weights and dramatically changing your diet, this simply isn’t true. It’s also important to remember that you can’t spot reduce fat. Your body works as a whole and, whilst you can tone a particular area, working the full body consistently along with a sensible diet will make the difference.”

Science Supports Strength Training for Weight Loss

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.

She Also Recommends Cardio

“In an ideal world, combine weights with cardio,” Caroline adds. Why is it important to do both? “While you may burn more calories in a cardio workout, strength training builds muscle. The two aren’t mutually exclusive and, for a leaner, fitter body, you should combine the two. Cardio is essential for heart health and for building stamina and endurance. At the same time, when we lift weights, we build muscle, boost metabolism and reduce our risk of injury,” she says.

Diet Matters

And, you can’t out-exercise a bad diet. “People think they can exercise, eat rubbish and still see great results,” she recently told The Daily Mail. “Sadly it doesn’t work like that. It’s about balance and moderation.” As for one main meal tip? “And protein with every meal – you need it for strength training,” she says.

Here Is What She Eats in a Day

Caroline starts her day with tea, coffee, and a banana. Then, after her 9 am workout class, she has breakfast, usually scrambled egg and avocado on sourdough. For lunc,h she likes chicken salad. Dinner might be a teriyaki salmon noodle stir-fry. As for snacks, she might have fruit and a bit of chocolate in the afternoon. She also drinks a lot of water.

Are you trying to lose weight but aren’t sure what to do? It may be as simple as implementing a few healthy habits into your routine, says one expert. Andrea Michelle is an online coach and certified personal trainer who helps “women love their bodies and get strong AF,” she writes in her Instagram bio. In a new post, she reveals what she did to lose 95 pounds. “I went from 240 lbs to 145 lbs naturally, & if I was someone who wanted to do the same in 2025, here’s what I’d do,” she captioned the post. “Steps to kickstart your weight loss journey.”

Step One: Eat in a Calorie Deficit

The first thing to do, is eat in a calorie deficit. “Calculate your TDEE (there are lots of online calculators) and ensure you are consistently eating below your maintenance requirements. This can be as little as 100- 200 calories below maintenance, as long as you are consistent you will lose fat,” she writes.

Step Two: Don’t Eliminate Foood Groups You Like

Next, don’t eliminate any food groups or foods you enjoy. “Work these foods into your meal plan, prioritize variety and plan for treats. All foods fit! If you enjoy the foods you are eating it will be much easier to stick to your deficit,” she suggests.

Step Three: Prioritize Protein

The third step is prioritizing protein. “Protein is so important while losing weight for a number of reasons. Firstly it increases satiety, keeping you fuller for longer. Secondly it boosts metabolism, it takes more energy for your body to break down protein than it does carbs or fat. Thirdly it preserves and builds muscle mass. During weight loss eating adequate protein helps your body preserve lean muscle mass, this means more of the weight you lose is fat,” she writes.

What Science Says About Protein

According to clinical trials, 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.

Step Four: Have a Step Goal

Next, have a step goal. “I did no formal cardio while losing weight. Instead, I focused on increasing my NEAT (non-exercise activity thermogenesis) and had a goal of hitting at least 10 thousand steps per day. If this is a big jump for you start by increasing your steps slowly over time. Pick a step goal that is challenging but realistic,” she writes.

How Many Steps?

How many steps should you walk? According to a 2018 study in Obesity, walking 10,000 steps a day is linked to weight loss and weight management. Other studies published by the Journal of 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.

Step Five: Lift Weights

“Focus on strength training regularly with progressive overload,” is step five. “Strength training is so important while losing weight because we don’t want to burn our muscle, we want to burn fat! If you strength train while in a calorie deficit you will lose less muscle than someone who isn’t exercising or only doing cardio,” she writes.

Science Supports Strength Training for Weight Loss

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.

Step Six: Be Patient

And the last step? Be patient. “Remember progress takes time. Short term fixes = short term results. Be patient with yourself and celebrate all the small wins along the way!” she writes.
