I'm a Bikini Fitness Competitor and Here's My #1 Rule for Weight Loss

Here's how you can help build muscle & blast fat.

FACT CHECKED BY Christopher Roback

People often ask me, what's my #1 rule for weight loss. And here, I want to share it with you. Hi, my name is Karla De Epstein (aka Coach Karli). I am 45 years old and a mom of two with a Masters in Science. I am also a professional NPC Bikini Athlete, a passion that started after having my second child when I turned 40. I got certified as a Macro Coach in 2021, and that’s when I created my own Nutrition Coaching Program: The MacroFit by PeruvianPrincessFit program, a program that provides virtual nutrition and lifestyle weight management coaching programs using the Flexible Dieting Approach.


I teach clients (lifestyle, bride-to-be, postpartum, couples, bikini competitors etc) how to reach their dream body in an effective and sustainable way without crazy diets, or restrictive approaches. I help change lives by creating good habits, losing weight, gaining lean mass, dropping body fat—all of this using a science-based approach, and all without giving up your favorite foods. Read on for my top 5 rules for weight loss—including #1.

1. No. 5 Rule for Weight Loss: Cardiovascular Activity

Let's start with my 5th rule for weight loss: cardiovascular activity. But not those types of HIIT classes that will have you jumping up and down and doing burpees and air squats and crazy stuff that will mess up your hairdo. No, no, no. Please stop doing that. Have you ever seen body builders doing that? Exactly. The trick here is to give your body the minimum necessary activity to burn calories without increasing cortisol (stress hormone). I am here to tell you that you don't have to kill yourself with those type of classes‚as a matter fact you should stop! A Low Intensity Steady State (LISS) type of cardio is sufficient for weight loss. Try forms of "pure" cardio such as StairMaster, elliptical, stationary bike or treadmill, as long as you are within your Heart Rate Burning Zone you will be burning calories just fine.

2. How to Calculate Your Heart Rate Burning Zone

Heart,Rate,monitor,Smartwatch,,Runner,Time,Shutterstock

It's simple. Deduct your age from 220 and apply 70% to that. For example if I am 50 years old my heart rate burning zone is 119. As long as you maintain that BPM in average throughout the entire cardio sesh, you will be burning beautiful calories. Bonus tip that I give all my clients: Watch an episode of your favorite Netflix show while doing cardio and time will fly!

3. No. 4 Rule for Weight Loss: Daily Step Count

Hikers,Walking,Mountains, outdoors, outside, rural, walking, exerciseShutterstock

My fourth rule for weight loss is having a daily step count of 8,000 (minimum). Make this a habit. Every single one of my clients tracks their steps daily. Listen, just wearing the Apple watch won't do the trick—you actually have to get up and move, check your tracker constantly, maybe 5, maybe 10 times per day, hold yourself accountable and make it happen. If you are sitting at an office all day, set up alarms every two hours to get up and move around. I pace my apartment when I am on conference calls for example—you'd be surprised at how many steps you can hit on a 30 min call! Can't do that either? Then allot yourself 20 minutes after each workout session and jump on the treadmill to just walk while you text or scroll through IG!

4. No. 3 Rule for Weight Loss: Emphasizing Resistance Training

My third rule for weight loss is resistance training. It's simple, the more muscle you have, the less you have to diet. Building muscle increases your metabolism. This won't take weeks or months, this is a process that can take years, but it's the most effective and proven way of losing fat. Those 2 pound dumbbells attached to the back seat of your stationary bike won't cut it either, come on, I know you are stronger than those pink weights. Try it and you'll see!

5. No. 2 Rule for Weight Loss: Prioritizing Sleep

Sleeping,sleep,snooze,bed,asleep,night,dreamShutterstock

My second rule for weight loss is definitely sleep. You can be doing everything right, eating right, exercising, lifting weights, doing cardio etc but if your sleep is not adequate your body is not in check and will not respond accordingly. Make some time for cat naps or maybe even a relaxation session like sauna or massage as these can help reduce cortisol.

6. The #1 Rule for Weight Loss: High Protein Intake

As a Certified Macro Coach who has helped hundreds of clients lose weight successfully, I must say that my #1 rule for weight loss is a high protein intake. At least 1 gram of protein per pound of body weight should be consumed. This ratio can be as high as 1.4 depending on the case.

7. It's Not as Hard as It Sounds!

The perfect time to start a "weight loss program" doesn't exist. Life will not all of a sudden clear your calendar for 3 months so you can start. Life will always happen, events will always happen, birthday parties, work, children, trips etc will always happen so stop waiting for the perfect moment and just start. It is not as hard as it sounds when you pick the right program and you have the right coach by your side!

8. The Last Word From Coach Karli

coach, Karli, Karla, De, EpsteinCoach Karla De Epstein

As a mother of two in her forties, bodybuilder and nutrition coach, I've learned that age is not an impediment to reach your physique goals. Your metabolism hasn't slowed down and, 95% of the time, the issue is not your hormones either. The main issue is discipline and commitment. And perhaps you are yet to find a diet that works for you. I am here to tell you that you don't have to be miserable on a juice or starvation type diet—you can eat a lot of food and still lose weight.

💪🔥Body Booster: When you give your body what it needs, that is when the body is happy and responds accordingly. Eat a balanced amount of macro-nutrients, high protein and a balanced amount of carbohydrates and fats, just what the body needs. It's not magic, it's science and the results are real.

Do you want to get rid of body fat but aren’t sure where to start? Mario Tomic is a fitness and nutrition coach who regularly shares videos to help people get in shape using research-based methods. In a new viral YouTube video, he reveals ten things you can do if you want to drop body fat fast. “I’m going to walk you through the exact steps I would take if I were back at 25 to 30% body fat and I wanted to get lean again,” he says in the clip.


Implement the Principles of Fat Loss

Mario starts by explaining that if he were out of shape right now, the first step he would take to start getting lean is implementing the first principles of fat loss. “These are the key behaviors that have the biggest impact on our body composition. And I know if I don't get these right, nothing else matters,” he says in the post.

Stay in a Calorie Deficit

So, what are these essentials? “Well, I know that I need to be in a calorie deficit to lose weight that is non-negotiable,” he says. “I know my numbers well because I've done this before, and if you're not sure where to start, a simple formula to figure out your starting calorie intake will take your goal weight in pounds and multiply that by 12. For example, 170 pounds or 77 kilo goal weight, you take 170 times 12, that'll be 2040 calories per day.”

Increase Calories If You Are Losing Weight Too Fast

“You would start there. And if you're noticing that you're losing weight too quickly, let's say more than two pounds or one kilo per week, you can always increase your calorie intake to make it a bit more sustainable,” he says.

Make Sure Your Diet Is Mostly Unprocessed Foods

“We don't all agree on what the ‘best’ diet is to create that calorie deficit. Instead of looking at what each diet does differently, I would like to look at what the most successful methods have in common. And that is keeping your diet 80, 90% minimally processed food, keeping high protein intake, lots of vegetables and simple repeatable meals while at the same time cutting out sodas, snacks, junk food and alcohol,” he says.

Lift Weights

The next thing to do as you are losing weight is to make sure you are not losing muscle, he says. “The best way to do that is lifting weights with the intent to get stronger. Here, I would start with a simple full-body training routine, five, or six exercises for all the major muscle groups three times per week and keeping the sessions to about an hour. That's more than enough,” he says.

Amp Up Your Protein Intake

“Also for building muscle and preserving muscle, I'd make sure that I'm getting my daily protein intake to about one gram per pound of my goal weight. So for 180 pounds or 81 kilos, that would be 180 grams of protein per day plus-minus 10 to 15 grams,” he says.

Prioritize Sleep

“Third, I would prioritize sleep,” he continues. “Sleep deprivation leads to less fat loss and more muscle loss and increases cravings and hunger, which makes staying consistent with fat loss incredibly difficult. Also, without good sleep, it's harder to recover and make progress in the gym. So my priority would be seven hours or more of high-quality sleep in a dark room with minimal interruptions and really make sure that I have a consistent sleeping schedule because I know that this will make everything easier.”

Track Everything

His third recommendation? “Start tracking everything,” he says. “By everything, I mean daily body weight, step count, weekly waist size, food lifting, and sleep. If you're not doing this, you're practically self-sabotaging. Tracking is the fastest way to figure out what's working and what's not, especially when you're just starting out on your journey. This is the highest return on investment activity.” This way, there will be no surprises, and you can adjust things accordingly if you aren’t losing weight. “Also, tracking is the ultimate form of self-accountability,” he continues. “When you're tracking, it's hard to ignore the evidence. You can clearly see when you're losing progress, and you're more incentivized to stay consistent.”

Fully Immerse Yourself Into Fitness

“Now the third step I would take if I were starting over again is fully immerse myself into fitness,” he says. “ Immersion is one of the most powerful and underrated things when it comes to staying consistent because maybe right now nobody around you prioritizes getting lean or fitness in general. And if you don't create your own mental space that's focused on these goals, it's going to be much harder to ignore the distractions and stay on track.” You can do this by “building your routine of watching fitness videos, reading about fitness, learning about this doesn't have to be my videos,” he says. Also, surround yourself with people with similar goals.

Finally, Be Adaptable

“Speaking of consistency, I would focus on being adaptable. As Darvin said, ‘It's not the strongest or the most intelligent that survive, but the most adaptable to change.’ I wouldn't go on this journey believing that it will all be perfect and a universe will conspire to arrange everything for me to get lean. No, that's delusional. Instead, I will trust my ability to adapt and learn. I know there will be a lot of mistakes, and this is actually what separates those who succeed from those who fail. Those who fail rely on one rigid plan. They try to force it into their life, and it might work on some days, but it won't work consistently. Those who succeed adapt.

It's not about perfection. It's about consistency. There's no perfect plan. No one knows exactly what's coming. But I can tell you one thing: if you trust your ability to adapt and figure it out as you go, you'll handle anything life throws at you, and you will ultimately get to your goal,” he says.

Have you ever felt frustrated with fad diets and quick-fix weight loss solutions that never seem to work long-term? Sarah Mackay, once struggling with her own weight, has transformed herself into a fitness and nutrition expert with her popular franchise, Lift With Sarah. Now, in a popular video, she's sharing her proven method for getting shredded in just 60 days—and, more importantly, how to maintain those results.


The Problem with Fad Diets

Sarah starts her video by addressing the elephant in the room: why most diets fail. "According to a 2007 review of weight loss studies, sustained weight loss after a period of dieting is actually the exception, not the rule," she points out. The issue lies in the approach itself. Quick fixes may lead to rapid initial losses, but without a strategy for long-term maintenance, it's all too easy to rebound.

The Three Key Principles of Long-Term Weight Loss

1. Diet: Creating a Sustainable Calorie Deficit

"Weight loss isn't actually as hard as many people make it out to be," Sarah explains in her video. "It all comes down to a calorie deficit where you just eat fewer calories on a daily basis than your body burns."

She emphasizes the importance of finding your maintenance calories and then creating a modest deficit. "A slower, more sustainable rate of weight loss means losing around 0.5% of your body weight each week," Sarah advises.

Catherine Gervacio, a Registered Dietician, adds a note of caution: "Rapid weight loss, including body fat loss, is often associated with extreme measures that can be detrimental to health. A safe and sustainable rate of weight loss is generally around 1-2 pounds per week."

2. Working Out: Finding the Right Balance

Exercise plays a crucial role in Sarah's approach. "Including exercise into your plan gives you a way to burn calories. It means you don't have to aggressively cut your food in order to stay within your calorie deficit," she explains in her video.

Sarah recommends a combination of cardio and weight training. "Getting in around eight 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," she shares.

3. Keeping the Weight Off: The Most Crucial Part

Sarah in her video emphasizes that consistency is key. "A consistent calorie deficit, no matter how long it takes you inevitably will lead to weight loss," she states. "It also turns healthy eating into a routine which helps you avoid weight gain rebounds after our dieting period has ended."

The Post-Diet Plan: Maintaining Your Results

One of the most critical aspects of Sarah's approach is the post-diet plan. She recommends immediately shifting to maintenance calories for your new weight once you've reached your goal.

"This direct approach, instead of adopting an approach such as reverse dieting, where you gradually come out of your deficit and up to your maintenance over time, allows you to come out of that deficit as soon as possible," Sarah explains in her video.

Gervacio adds, "It's very important that before starting any rapid fat loss program, consult with a healthcare professional. They can assess your individual health status and provide guidance on whether such an approach is safe for you."

The Role of Hydration and Sleep

While not explicitly mentioned in Sarah's approach, Gervacio emphasizes the importance of hydration and sleep in fat loss efforts. "Adequate hydration can help regulate appetite," she explains. "As for sleep, it affects the regulation of hormones related to appetite and metabolism."

Conclusion: A Balanced Approach to Getting Shredded

Sarah's method provides a balanced, sustainable approach to getting shredded. By focusing on creating a moderate calorie deficit, incorporating regular exercise, and having a solid plan for maintaining results, it's possible to achieve significant fat loss in 60 days.

However, it's crucial to remember Gervacio's advice: "Shift your mindset from just weight loss to overall well-being. Consider factors like energy levels, mood, sleep quality, and overall health as important markers of success."

By following these principles and focusing on long-term health, you too can achieve the shredded physique you desire - and, more importantly, maintain it for the long haul. And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

Struggling with stubborn belly fat? You're not alone. Louise Rodhouse, a 29-year-old mum-of-two from Slough, United Kingdom, knows the frustration all too well. But she's living proof that transformation is possible. Starting at 269 pounds in January 2020, Louise lost an incredible 120 pounds in just 14 months, going from a size 22 to a size 8. Now, she's sharing her journey and the lessons she's learned along the way.


Debunking Quick-Fix Myths

Louise doesn't sugarcoat it: "I'm going to tell you something that you probably might not want to hear." In her post, she explains that there's no magic waist trainer, specific exercise, pill, or cream that will melt away belly fat. "The secret is there's no secret apart from eating in a calorie deficit," she states. This means consuming fewer calories than your body burns each day.

The Risks of Rapid Fat Loss

Colette Micko, MS, RDN, CDES of Top Nutrition Coaching, adds: "There are many potential risks of trying to lose body fat too quickly, and most are associated with extreme measures of calorie restriction such as fasting and/or very low-calorie diets."

The Truth About Spot Reduction

"You cannot spot reduce fat no matter what anyone tells you online," Louise underlines. She notes that genetics play a role in where your body stores and loses fat. "For me, I notice that when I start to lose body fat, I lose it on my upper body first... and then it gradually comes down." She adds, "With my lower stomach, obviously I had the apron belly... that was literally one of the last places my body fat went from."

Beyond the Scale: Measuring Body Fat

Courtney Pelitera, MS, RD, CNSC, explains: "Measuring body fat percentage can be more helpful in assessing health than weight alone. This is because muscle weighs more than fat, therefore affecting overall weight, even if an individual is very healthy." You can benchmark your progress with this useful Lean Body Mass Calculator.

Finding Your Calorie Sweet Spot

To lose weight, Louise recommends finding your maintenance calorie level and reducing it by 250-500 calories. She suggests using apps like MyFitnessPal or online calculators like TDEE calculator.net to determine your calorie needs. "The bigger deficit you are in, the less sustainable it is because the more hungry you're going to be," she warns, advocating for a slow and steady approach.

Setting Realistic Weight Loss Goals

Jordan Hill, MCD, RD, CSSD, supports this approach: "In general, a 0.5-2 lbs loss/week is considered safe and sustainable. Some folks may lose a little more or less on any given week though. It's important to remember that weight loss is not linear and often times a person's weight will fluctuate up and down throughout their weight loss journey."

Nutrition: The Foundation of Fat Loss

While a calorie deficit is key, Louise stresses the importance of nutrition: "When you lose weight, you want to focus on your health, and the best way to do it is to prioritize whole foods, healthy foods, fruits, vegetables." She recommends aiming for 1-1.5 grams of protein per pound of body weight and not fearing fruits, stating, "Fruits are fruits, they've got nutrients, eat damn fruits."

The Power of Plant-Based Foods

Megan Hilbert, MS, RDN, adds: "Eating more plant based foods (nuts/seeds, whole grains, fruits, vegetables, etc.) can also help promote weight loss due to the fiber and phytonutrient content that helps increase satiety and influence our metabolism through the gut microbiome."

Simple Movement: A Game Changer

Louise underlines the power of simple movement: "Walking is really good to lose weight, literally just increasing the amount you walk, you'll be surprised at how much that helps." She suggests starting with a 30-minute daily walk and gradually increasing activity levels.

Balancing Cardio and Strength Training

Hilbert expands on this: "For the fastest, healthy fat loss it's important to incorporate at least 150 minutes of moderate aerobic activity in, or 75 minutes of vigorous aerobic activity in a week. This, plus strength training around 3 times a week is a good balance, as added muscle mass helps to burn fat and increase metabolic output even while in a rested state."

The Long Game: Patience in Fat Loss

"You just need to stick to it as long as possible for your body to lose the body fat around your stomach," Louise advises. She reminds readers that the process can take time: "It could take a year or two years, it could take a very long time depending on how much body fat you have to lose."

Embracing Sustainable Lifestyle Changes

Annette Snyder, MS, RD, CSOWM, LD, underlines: "Slower, long-term work includes a focus on building in lifestyle changes and addressing any challenging thoughts about food and body. You learn to work with your body instead of against it. It's easier to adapt to and maintain vs something very intense for a short time."

The X-Frame: Sculpting Your Physique

For those seeking a more dramatic waist-to-hip ratio, Louise shares a bodybuilding secret: "Build muscle in your back like your lats and your shoulders... also build up your legs and your glutes." This creates an "X-frame" that can make your waist appear smaller in comparison.

Sleep and Hydration: Unsung Heroes of Fat Loss

Pelitera notes: "Poor sleep habits have been linked with an increase in overall energy intake and a decrease in metabolism. These two aspects alone are going to make achieving fat loss at any rate more difficult."

The Takeaway: Sustainable Success

Louise's journey proves that with dedication, patience, and the right approach, significant weight loss – including stubborn belly fat – is achievable. As she puts it, "Slow steady wins the race. You've got this guys, it will eventually go." Remember, it's not about quick fixes, but sustainable, health-focused changes that lead to lasting results.

As 2025 begins, millions of people are making the same old weight loss resolutions—but this year can be different. Celebrity physical therapist and strength coach Jeff Cavaliere, whose science-based fitness guidance has earned him nearly 14 million YouTube subscribers on ATHLEAN-X, has distilled effective weight loss into four simple rules that he swears will work for anyone. "I've never seen this fail," Jeff emphasizes, "I know how to do it. I've done it my whole life." Ready to make 2025 the year you finally achieve your weight loss goals? Here's your blueprint for success.


First Step For 2025: Know Your Type—Are You a Grazer or an Overeater?

Before diving into any weight loss plan, you need to identify your primary challenge. "99 times out of a hundred it has to do with an inability to structure your eating," Jeff explains in his video. He's observed that people typically fall into one of two categories: those who struggle with portion control (overeaters) and those who can't maintain consistent meal times (grazers).

Rule #1: Control Your Eating Window

For grazers, Jeff's first rule involves time-restricted eating. "The number one most effective method I've seen people use to help them with grazing is to restrict eating to specific windows," he states. Start with an 8-hour eating window (16 hours fasting), then gradually progress to 6 hours as you become comfortable.

Make Time-Restricted Eating Work For Your Schedule

Success with time restriction requires strategic timing. "You cannot structure this overlapping the time period that you struggle with right now," Jeff advises. If workplace snacking is your downfall, schedule your eating window to eliminate half of those problematic hours.

Family dinner non-negotiable? No problem. "If you like to have dinner with your family, you need to make sure that your eight-hour window includes that time for dinner and then you back it up or push it forward," Jeff explains. This flexibility ensures the plan fits your 2025 lifestyle.

Rule #2: Master The Plate Method

For overeaters, Jeff's second rule introduces a foolproof portion control system. "99 times out of a hundred, it's a problem with carbohydrates because they're the most gratifying and the most likely to be over eaten," he notes. His solution? A precise plate division that naturally controls portions:

  • 40% protein (largest portion)
  • 35% fibrous carbohydrates
  • 25% starchy carbohydrates (smallest portion).

"I don't want you to build this thing all the way out to the camera," Jeff warns about portion height. Keep portions reasonable and flat rather than piled high.

Rule #3: Protect Your Muscle

The third rule focuses on preserving muscle while losing fat. "I don't want to see you lose muscle in the process because losing active muscle or lean tissue is going to cause your metabolism to slow down," Jeff warns. His specific prescription: "You have one to 1.2 grams of protein per pound of body weight."

This rule is crucial because, as Jeff explains, "I don't care and I don't want you to care just about losing weight. I want you to make sure you're losing body fat." This approach ensures your metabolism stays strong throughout your 2025 weight loss journey.

Rule #4: Master Your Hydration

The final rule involves proper hydration: "0.5 to, let's say, 0.75 ounces of water per pound of body weight." For a 200-pound person, this means consuming between 100 and 150 ounces daily.

Finding it challenging? Jeff offers a practical solution: "Drink whatever the hell you want, provided it's zero calories." This includes:

  • Green tea
  • Unsweetened iced tea
  • Sparkling water.

"You'll shock yourself at how little you actually drink in a day if you actually measure it," he notes.

Put It All Together: Your 2025 Action Plan

"When I tell you that it is this simple, it is literally four steps simple," Jeff emphasizes. Here's your roadmap for 2025:

  1. Identify your type (grazer or overeater)
  2. Implement your primary solution (time-restricted eating or plate method)
  3. Protect your muscle with adequate protein
  4. Master your hydration.

"If we follow this, you're going to have the ability to control the main problem you're having right now," Jeff concludes. "This works every single time." By following these four rules consistently throughout 2025, you're not just making another resolution—you're implementing a proven system for lasting results.

Losing weight isn’t just about cutting calories and eating less. It also involves eating the right kinds of food. “If you're looking to lose weight, choosing nutrient-dense, high-fiber, and protein-rich foods can help keep you full and support your metabolism,” says Body Network’s Resident RDN, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CP. We asked her to put together a list of the top foods you should fuel up with to lose weight, and here are 10 of them.

Leafy Greens

Leafy greens, including spinach, kale, arugula, Swiss chard, Romaine, and mustard greens, should be a mainstay in your refrigerator. “Low in calories but packed with fiber, vitamins, and minerals,” she says. “Leafy greens are a high-volume food, which helps with satiety while keeping calorie intake low.”

Eggs

Eggs might not be cheap right now, but they offer a lot of bang for the buck in terms of nutrients. “High in protein to keep you full longer,” says Collingwood. “A lot of the nutrition is in the egg yolk, but so are many calories. Split the difference using some whole eggs and combine with a few egg whites.

Lean Protein

Next up, you need to eat a lot of lean protein, including chicken, turkey, lean beef, seafood, and other fish, to lose weight. “Helps to preserve muscle mass during weight loss,” Collingwood explains. “Helps reduce hunger and keeps you satisfied.”

Greek Yogurt

Another item to keep stocked up on for weight loss? Greek yogurt. “High in protein and probiotics for gut health,” she says. “Greek yogurt can help with appetite control and digestion.”

Berries

Berries, especially blueberries, blackberries, strawberries, and raspberries are also great for losing weight as they are rich in fiber and antioxidants. “Can satisfy sweet cravings with fewer calories,” says Collingwood.

Cruciferous Vegetables

Cruciferous vegetables like broccoli, cauliflower, and Brussels sprouts are another great option. “Low in calories but high in fiber and antioxidants and vitamins,” Collingwood says. “The high fiber content can help keep you full longer.”

Legumes

Legumes, including lentils, chickpeas, and black beans, are essential for weight loss.

“High in plant-based protein and fiber which helps to keep you full for longer and can help stabilize blood sugar,” says Collingwood.

Oats/Oatmeal

Oats and oatmeal should always be in your pantry. “Whole grain that is high in soluble fiber, which aids digestion and prolongs fullness,” explains Collingwood. “Can help to regulate blood sugar due to soluble fiber. Combine with a protein (make oatmeal with milk, add protein powder, make overnight oats with Greek yogurt) for a complete meal.”

Nuts and Seeds

Nuts and seeds are great to have on hand for healthy snacking. Collingwood likes almonds, pistachios, walnuts, hemp, chia seeds, and flaxseeds. “Packed with heart-healthy fats, fiber, and protein,” she says.

Avocados

What you ate in your twenties, thirties, and forties to lose weight might not work as you age. According to an expert, some foods shouldn’t be on your plate in your fifties and beyond. Jon Williams is a fat loss expert who helps men and women lose 20-plus pounds of body fat. In a new Instagram post, he gets honest about fat loss and diet. “The fittest people I know who are in their 50s and 60s, avoid these 8 foods at all costs when they are trying to lose weight,” he writes.

Processed Sugars

The first no-no? Processed sugars. “High in calories and low in nutrients, they can lead to weight gain, insulin resistance, and increased risk of chronic diseases,” he says.

White Bread

While you don’t have to go on a no-carb diet to lose weight, you might have to ditch white bread. “Made from refined flour, it lacks fiber and can cause spikes in blood sugar levels, which is particularly concerning as metabolism slows with age,” says Williams.

Fried Foods

Another type of food you can’t eat if you want to lose weight? Fried foods. “High in unhealthy fats and calories, they can contribute to heart disease and obesity,” he says.

Soda and Sugary Drinks

Don’t drink your calories, suggests Williams. Soda and sugary drinks should be avoided. “Loaded with sugar and empty calories, they can lead to weight gain and increase the risk of type 2 diabetes,” he explains.

High-Sodium Foods

Salty foods might taste good, but generally, high-sodium items should be avoided. “Processed snacks and canned soups can contain excessive salt, which is linked to high blood pressure and heart issues,” says Williams.

Pastries and Cakes

You don’t have to avoid everything sweet, but pastries and cake aren’t going to do you any favors if you are trying to slim down. “These are often high in sugar, unhealthy fats, and refined carbohydrates, contributing to weight gain and health issues,” he says.

Trans Fats

Read labels and avoid food with trans fats. “Found in many processed foods, these fats raise bad cholesterol levels and lower good cholesterol, increasing heart disease risk,” says Williams.
