So, you finally made the decision to start your workout routine and get into shape. But how will you know when, or even if, it is working? According to certified fitness trainer, Jason Kozma, aka Mr. America and Mr. Muscle Beach, is a champion bodybuilder who trains clients at Santa Monica-based High Performance Personal Training, there are a few signs that your routine is actually burning fat.


Clothes Fit Better

The first sign you are burning fat is if your clothes are fitting better. “You will notice changes in how your clothes fit, such as feeling looser around the waist and hips,” he says.

Increased Energy Levels

You might think that exercising makes you tired, but it actually has the opposite effect. Kozma says you should have “more energy throughout the day and reduced feelings of fatigue” when you are in the fat-burning process.

Improved Sleep Quality

Have you noticed your sleep quality is improving? “Falling asleep faster and experiencing deeper, more restful sleep” is a definite sign you are burning fat.

Visible Muscle Definition

Visible muscle definition is another sign. Expect “more defined muscles as fat decreases and muscle mass becomes more apparent,” says Kozma.

Steady Weight Loss

Are the numbers on the scale going down? Steady weight loss means you are burning fat, says Kozma. Look out for “a consistent decrease in weight over time, even if it's gradual.”

Reduced Body Measurements

Another way to know if your fat is dissolving? Reduced body measurements, says Kozma. “Smaller measurements around key areas such as the waist, hips, thighs, and arms,” are sure signs.

Increased Strength

Are you feeling stronger? “Gaining strength and being able to lift heavier weights or perform more reps” is another sign.

Better Endurance

Can you go harder for longer? “Better endurance” and “improved stamina during workouts and daily activities,” is a fat-burning hint.

Reduced Appetite

If you are burning fat it is likely your appetite is reduced. “A more regulated appetite and fewer cravings, especially for unhealthy foods,” is normal, says Kozma.

Lower Body Fat Percentage

Lower body fat percentage is another obvious sign. “A decrease in body fat percentage, as measured by calipers or body composition scales,” will be a good indicator, he says.

Improved Mood

Are you feeling happier? “A more positive mood and reduced symptoms of stress, anxiety, and depression” are symptoms of fat burning, according to Kozma.

Healthier Skin

You may even notice an improvement in your complexion. Healthier skin that is “clearer and more vibrant” is often a result of better hydration and a healthier diet.

Enhanced Mobility

As you burn fat you are more likely to experience enhanced mobility. This can include “better flexibility and range of motion in joints and muscles,” Kozma maintains.

Increased Motivation

Increased motivation is another benefit of fat burning. This could be a “greater enthusiasm and commitment to going to the gym,” Kozma says.

Better Digestions

Your gut health will likely improve, and you may experience better digestion. Improved digestive health may include “less bloating and regularity,” Kozma says.

Stable Blood Sugar Levels

Stable blood sugar levels are another positive side effect. This could be in the form of more consistent blood sugar levels, reducing spikes and crashes, Kozma explains.

Improved Cholesterol Levels

Another health marker to look out for? Improved cholesterol levels. “Lower LDL (bad) cholesterol and higher HDL (good) cholesterol,” he says.

Lower Resting Heart Rate

You might also notice a lower resting heart rate. “A decrease in your resting heart rate indicates improved cardiovascular health,” Kozma says.

Visible Fat Loss in Stubborn Areas

You may also notice visible fat loss in stubborn areas. This might be a reduction of fat in areas where it's typically harder to lose, like the belly or thighs, he says.

Positive Feedback

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.

Trying to figure out if your diet is actually working? You're not alone. While the scale might show lower numbers, that doesn't always mean you're losing fat. Dr. Jenny Le, a Family Medicine Physician and fitness enthusiast with over 110,000 YouTube subscribers, has helped countless patients identify true fat loss. Through her medical practice and personal experience as a doctor mom, she reveals the real signs your body is burning fat, not just losing water weight or precious muscle.

Your Body Composition Is Changing Despite the Scale

The first sign of real fat loss isn't just about numbers on the scale. "You are going to lose weight, but you don't want to look skinny fat," Dr. Le explains to her patients. When you're losing fat while maintaining muscle, your body becomes more toned and firm, even if the scale doesn't show dramatic changes. This is what we want - a transformation in body composition, not just weight loss.

You're Maintaining Strength in Your Workouts

One clear sign of successful fat loss is maintaining your strength during workouts. "Just because your calories decrease does not mean that your intensity at the gym should also decrease," Dr. Le emphasizes. When you can maintain your training intensity while eating less, it's a strong indicator that your body is preserving muscle and primarily burning fat for fuel.

Your Hunger Isn't Out of Control

Sustainable fat loss comes with manageable hunger levels. "When people have a larger higher protein breakfast, they tend to feel more full and choose to eat less throughout the day," Dr. Le shares from her clinical experience. If you're not experiencing extreme hunger or binge eating episodes, it's a good sign your body is adapting to fat burning.

Your Energy Levels Are Stable

Proper fat loss shouldn't leave you exhausted. In fact, when you're burning fat effectively, your energy levels remain relatively stable. "If you're really tired, if you can't sleep, if you're really anxious, if you are angry all the time, there's lots of different signs that your body is telling you, 'Hey, I'm over this,'" Dr. Le warns. Stable energy is a positive sign of healthy fat loss.

You're Hitting Your Protein Goals

A key indicator of effective fat loss is consistently meeting your protein targets. "Anywhere from 0.8 to one grams per pound of lean body mass is a good starting point," Dr. Le recommends. When you're hitting these numbers while in a calorie deficit, you're supporting muscle preservation and healthy fat loss.

Your Clothes Fit Differently

While a scale measures overall weight, changes in how your clothes fit can reveal fat loss. "You can gain weight very, very, very slowly," Dr. Le explains when discussing body recomposition. Your clothes might feel looser in some areas while fitting better overall, indicating you're losing fat while maintaining or even gaining muscle.

Your Metabolism Is Adapting, Not Crashing

Perhaps the most important sign of healthy fat loss is a stable metabolism. "Don't worry, your body adapts. Just as your metabolism adapts going down, your metabolism will adapt going up as well," Dr. Le reassures her patients. When you can gradually increase your calories without immediate weight gain, it's a sign your body has maintained its metabolic health during fat loss.

The key to lasting fat loss isn't just about eating less – it's about eating right and maintaining your body's metabolic machinery. "If you're mainly eating whole foods high in protein, I guarantee you you're not going to gain back all the weight that you've lost," Dr. Le tells her patients. By watching for these seven signs, you can be confident you're losing fat while protecting your hard-earned muscle and metabolic health.

Remember, true fat loss is a gradual process that leaves you feeling stronger, not depleted. Continue resistance training, maintain your protein intake, and pay attention to these signs. Your body will tell you when you're on the right track. And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

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.

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 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.

We are committed to bringing you researched, expert-driven content to help you make more informed decisions around food, health, and wellness. We know how important making choices about your overall health is, and we strive to provide you with the best information possible.

We've all been there—trying diet after diet only to end up back where we started. Fitness coachSarah Mackay knows this struggle all too well. Once a gym-avoider battling an eating disorder, Sarah transformed her life through fitness and discovered what really works for long-term results. "After 60 long days of dieting, I'm finally shredded and it was so much easier than I thought it was going to be," Sarah shares. Keep reading to discover her three key principles that will help you not just lose weight, but keep it off for good.

Why Most Diets Fail

The world is full of fad diets promising quick results, but statistics show they rarely work long-term. "According to a 2007 review of weight loss studies, sustained weight loss after a period of dieting is actually the exception, not the rule," Sarah explains in her video. The problem isn't you—it's how these diets are designed. Quick fixes lead to quick losses, but without a maintenance strategy, you'll likely bounce back to old habits once the diet ends.

Understanding Calorie Deficit

Weight loss comes down to one simple principle: calorie deficit. "Weight loss isn't actually as hard as many people make it out to be and it all comes down to a calorie deficit, where you just eat fewer calories on a daily basis than your body burns," Sarah says. Your body burns calories through resting, exercise, non-exercise activities, and digestion. Creating a deficit means eating less than your body burns daily.

Finding Your Maintenance Calories

Before starting any weight loss journey, you need to know your starting point. "Calculating your maintenance calories is actually nowhere near as hard as it may sound," Sarah points out. Your maintenance calories are simply how much you need to eat to maintain your current weight. Once you have this number, you can create your deficit by eating less than this amount each day.

Choosing Your Weight Loss Rate

You need to decide how quickly you want to lose weight. "A slower, more sustainable rate of weight loss means losing around 0.5% of your body weight each week," Sarah recommends. For faster results, you can aim for 1% weekly loss, but this requires a larger calorie cut. For a 135-pound person eating 2,500 maintenance calories, a 0.5% loss means reducing to 2,150 calories, while 1% requires cutting to 1,825 calories daily.

Why Slower Is Often Better

The temptation to lose weight quickly is strong, but patience pays off. "A more sustainable rate of loss allows you to have a little bit more flexibility in your diet and enjoy free meals without completely derailing your progress," Sarah explains. This balance isn't just more enjoyable—it's actually the key to long-term success rather than yo-yo dieting.

Adjusting As You Go

As you lose weight, your body adapts by burning fewer calories. "After a few weeks of dieting, your initial deficit probably won't be much of a deficit at all," Sarah warns. This explains why many people hit plateaus despite doing everything "right." The solution is simple: periodically drop your calories down a bit more or increase your activity level to maintain your deficit.

The Exercise Factor

While diet alone can create a deficit, exercise gives you more flexibility. "Including exercise into your plan gives you a way to burn calories and means you don't have to aggressively cut your food in order to stay within your calorie deficit," Sarah shares. Plus, working out is what gives you that toned, shredded look once the weight comes off.

Finding Exercise That Works For You

Not all workouts are created equal when it comes to calorie burn. "Exercises that are higher intensities, such as running or HIIT, will burn much more calories within a small time frame in comparison to lower intensity exercises such as walking," Sarah points out. The best workout plan is one you can maintain long-term, whether that's daily walks or intense HIIT sessions.

Sarah's Personal Sweet Spot

Everyone's ideal exercise routine is different. "Personally, getting in around 8,000 to 15,000 steps each day and doing a light to moderate form of cardio two to five times a week seems to be the sweet spot for me that I can maintain in the long run," Sarah reveals. For a more shredded look, she recommends weight training about three times weekly plus eating around one gram of protein per pound of body weight.

The Consistency Factor

Weight loss isn't about perfection—it's about persistence. "A consistent calorie deficit, no matter how long it takes you, inevitably will lead to weight loss," Sarah emphasizes. Consistency turns healthy eating into a routine, helping you avoid weight gain rebounds after dieting. Don't worry about slip-ups; what matters is getting back on track quickly.

The Post-Diet Plan

Most diets fail because they don't address what happens after you reach your goal. "Without a plan to maintain our weight once it's off, it is inevitable that we go back to old eating habits and rebound on the weight that we've just lost," Sarah cautions. The key is having a concrete strategy for maintenance from day one.

Transitioning To Maintenance

Once you reach your goal, it's time to shift gears. "You're going to need to come out of your deficit straight away and shift immediately to your maintenance calories for your new weight," Sarah advises. This direct approach lets your body recover from the stress of dieting while preventing the urge to binge that often happens after restriction ends.

Finding Your New Maintenance Level

Your new maintenance calories won't be the same as before you lost weight. "Finding your sweet spot for your new maintenance calories will take a little bit of trial and error," Sarah says. Start by adding about 200-600 calories to your diet intake, then monitor your weight. If it remains stable for a week, you can gradually add more calories until you find your maximum maintenance level.

The Freedom Factor

The goal of maintenance is to eat as much as possible while keeping your weight stable. "The more food that you are able to eat, the less you will feel restricted and the more likely you are able to stick to a healthy eating plan that allows you to maintain your new body weight," Sarah explains. This freedom is what makes your results truly sustainable for life.

Conclusion

Following these three principles—smart dieting, appropriate exercise, and having a maintenance plan—is the key to not just getting shredded, but staying that way. Sarah's approach proves that weight loss doesn't have to be miserable or temporary. By focusing on these fundamentals and avoiding quick fixes, you can transform your body and keep it that way for good.

Are your blood sugar levels high? While there are drugs that stabilize blood sugar, maintaining a healthy diet is also an effective tool for lowering it. Sophie Lauver of Aeroflow Diabetes, a Registered Dietitian and Board Certified Health and Wellness Coach, spoke to Body Network about the best foods to reduce blood sugar levels. “Unfortunately, one food alone won’t reduce blood sugar levels. But, a well-planned diet including lots of nutrient-dense foods (and the inclusion of physical activity) can play a huge role in improved blood sugar levels,” she says. According to Lauver, below are some foods that, as part of a healthy diet and lifestyle, will help lower blood sugar.

Berries

The first food you should eat to reduce blood sugar? Berries. “Berries are high in fiber and low in carbohydrates and can slow glucose absorption into the bloodstream,” says Lauver. “They’re rich in antioxidants and can reduce and repair stress put on our bodies.” Blueberries, strawberries, and raspberries are all great options.

Lentils

Lentils are an excellent lean protein that contains carbohydrates. “This mighty pairing of lean protein + carbohydrate can keep you full and mitigate the impact of glucose spikes into your bloodstream, stabilizing your blood sugar,” she says. How should you eat lentils? Add them to soups, cook and eat as a side, or throw them in salads.

Quinoa

Quinoa is a whole grain, “meaning the grain has not been stripped of its natural vitamins, minerals, and nutrients,” she says. “Whole grains have more fiber than refined grains and have a lower glycemic index.” Eat quinoa instead of white rice, or even add into a soup for some texture.

Nuts and Seeds

Nuts and seeds are another great blood sugar-lowering food. “Healthy fats, like those from plant-based nuts and seeds, when paired with carbohydrates, can slow the absorption of carbohydrates and allow for less of a spike in blood sugar,” she says.

Flaxseed

Also, infuse your menu with flaxseed. “Flaxseed is a powerhouse that is rich in Omega 3s, fiber, and antioxidants, and may help lower blood pressure, lower triglycerides, reduce the risk of some cancers, help digestion, and improve insulin sensitivity,” she says. “Omega 3s may aid in glucose control, and research is ongoing.” Not sure how to eat flaxseed? It makes a great addition to a smoothie or smoothie bowl. And if you enjoyed this article, take advantage of these20 Superfoods for People Over 50.

Everyone knows that eating an abundance of fast or calorie-rich food – or skipping exercise – can cause you to pack on pounds. However, there are a lot of habits that will also make you gain more weight that are a little more undercover. Are you making any avoidable mistakes that can make you gain more weight? Body Network asked Danielle Pashko, Functional Nutritionist, health coach, and author of Breaking Your Fat Girl Habits: weight loss mistakes even healthy chicks make! to reveal some of the most common missteps people take that lead to weight gain.

1. "I Can Eat Whatever I Want If I Exercise."

If you think you can eat whatever you want if you exercise, “think again,” says Pashko. “Over-exercising can trigger intense hunger, leading you to consume more calories than you burned. Without mindful eating, workouts won’t cancel out overeating,” she explains.

2. "Gluten-Free Means Healthy."

Gluten-free does not mean healthy, according to Pashko. “Many gluten-free products—like breads, pastas, and cereals—are higher in carbs and calories than their traditional counterparts. They may be free of gluten, but that doesn’t make them a weight-loss-friendly choice,” she says.

3. "Adding MCT Oil or Butter to Coffee Boosts Metabolism."

Adding MCT oil or butter to coffee doesn’t necessarily boost metabolism. “If you’re following a ketogenic diet or intermittent fasting, this might work. But if you’re also consuming moderate to high carbs, adding extra fat can quickly lead to weight gain,” Pashko explains.

4."Sushi Is Just Rice and Fish."

Sushi isn’t always the best choice for weight loss. “Many sushi rolls are loaded with hidden sugars, sauces, and fried ingredients. Even seemingly healthy dishes like chicken teriyaki can be packed with hidden calories and additives,” says Pashko.

5. "It’s From a Health Food Restaurant, So It Must Be Good for Me."

Health food restaurants don’t always serve diet foods. Pashko points out that many “healthy” restaurant dishes—like oversized salads or grain bowls—can easily exceed 1,000 calories. “I’ve analyzed menus firsthand and was shocked at the sneaky ingredients hiding in so-called health foods.”

6. "Intermittent Fasting Helps With Weight Loss—No Matter What."

Intermittent fasting isn’t a foolproof plan for losing weight. “While fasting can be effective, some people become so ravenous at their first meal that they overcompensate by eating double. Portion control is still essential for success,” says Pashko

7. "Trendy Supplements Like Creatine Enhance Every Diet."

Trendy supplements might seem like a quick-fix for weight loss, but they aren’t. “Creatine and other trendy add-ins can cause water retention and unintended weight gain. Before following the latest TikTok wellness hack, consider whether the benefits outweigh the side effects,” she says.

8. "Eating a Big Meal Before a Workout Fuels Performance."

No, eating a big meal before exercise won’t necessarily fuel your performance at the gym. “A light snack can help stabilize blood sugar, but a full meal before exercise often leads to post-workout hunger—resulting in two full meals and undoing the calorie burn,” says Pashko.

9. "Strength Training Alone Is Enough to Slim Down."

Strength training is hyped as the best workout for fat loss. However, lifting might not be enough if you want to lose weight. “Resistance training is essential for metabolism and muscle health, but weight loss is difficult without incorporating some form of cardio,” Pashko maintains.

10. "Healthy Snacks Are Unlimited."

Just because a snack is healthy, doesn’t mean you can eat unlimited amounts. “Snacking is only beneficial when it stabilizes blood sugar and prevents overeating at meals,” Pashko points out. “Keep snacks under 200 calories, with less than 5g of sugar and 30g of carbs, plus protein and fiber to keep you full. Munching on an entire bag of organic popcorn or gluten-free pretzels? That’s a disguised way of eating junk food and marketing it as healthy. Stick to real food like hard-boiled eggs, Greek yogurt, or a few turkey slices.” And if you enjoyed this article, don't missthese 8 High-Protein Foods with Nearly Zero Calories That Melt Fat.
