Losing weight fast can seem like a dream come true. However, there are some negatives that come along with rapid weight loss you should consider before taking a GLP-1 drug like Ozempic or going on a drastic diet. We asked some of the top doctors, plastic surgeons, and weight loss experts to reveal major side effects of rapid weight loss – via either the natural way or using weight loss drugs – to look out for.

Fat Deposits

While losing weight reduces overall body fat, deposits still exist. “Treatments like Ozempic help with rapid weight loss, but fat still exists in a reduced size,” Vishal Verma, MD, Founder of Revive Med Spa, says, recommending treatments like CoolSculpting to help “eliminate the fat cells, furthering the long-term results.”

Uneven Skin Tone or Texture

There is also the appearance of uneven skin tone/texture with weight loss. “Stretch marks may become more apparent with weight loss, so resurfacing treatments can help even tone and texture for a more youthful, radiant glow,” says Dr. Verma. “

Hair Loss

Hair loss can be a potential side effect of rapid weight loss. This is often due to nutrient deficiencies, stress, and hormonal changes that occur when the body loses weight quickly.

Losing weight can impact fertility. "Weight loss can generally be associated with increased fertility by restoring normal ovulation in people who have PCOS or other causes of abnormal cycles," said Dr. Daniel Drucker, a professor and researcher at the University of Toronto's Mount Sinai Hospital and a pioneer of research into GLP-1 in an interview with CNN.

Ileus

Ileus, “which is a temporary condition where your intestine can't push food and waste out of your body, is an unofficial side effect due to the effects of slowing down the gut movement,” says Kylie Bensley, MS, RD and founder of Sulinu Nutrition. If you think you have this, she recommends seeking medical advice.

Muscle Loss

Sue Decotiis, MD, NYC weight-loss doctor, notes that there are a few reasons why rapidly losing weight leads to muscle loss. “There are many people who lose muscle because they aren’t drinking enough water. Water intake is imperative. You really need to drink a lot of water when you’re burning that much fat. If you are not drinking enough water, your body won’t burn fat, and you’ll lose muscle,” she says. The other reason is losing weight rapidly, which often leads to losing muscle. To mitigate this, make sure to lift weights or do another form of muscle-strengthening exercise.

More Self-Esteem

A positive side effect? “I’ve seen a lot of positive effects on personality in my practice. When people lose weight, they have better self-esteem, and they feel more confident in their own skin,” says Dr. Decotiis. “I have people who were using sedatives for anxiety or depression, and then when they lost weight, they felt better and didn’t need them as much. My patient who has ADHD felt they had better focus and concentration.”

Eating Disorder Triggering

If you have eating disorders in your history, rapidly losing weight can be triggering. “If there’s a history of an eating disorder, that’s when people can run into some problems. People who used food as a crutch and would go to food for comfort may miss food a lot because they used to get that dopamine hit from using food to make them feel better,” explains Dr. Decotiis. She recommends anyone who has struggled with these sorts of issues to work with a therapist while losing weight.

Decreased Libido

Losing weight might impact your sex drive. “In the beginning, realize there’s a tremendous metabolic change going on in the body that can cause fatigue, and when someone is tired, their libido goes down. As time goes on and you lose more weight and feel better, libido will go back to normal because you’ll feel more confident and better without clothes on,” says Dr. Decotiis.

Saggy Skin

According to Dr. Decotiis, some people are complaining about having a saggy butt, face, or loose skin after rapidly losing weight, which has to do with fat loss. “Your skin stretches when you gain weight, so when you lose a lot of weight, sometimes your skin doesn’t fully go back to normal,” she says. “Think of a woman who’s pregnant. When she has a baby, sometimes her stomach takes time to go back to how it was before.” One way to mitigate this effect is by weight training during the weight loss process. “Additionally, as you age, you have less elasticity in your skin, and you cannot produce as much collagen. Your skin bounces back better when you’re younger,” she says.

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

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

Kelsey_Kunik_graciouslynourished2graciouslynourished/Instagram

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

Here Are the Signs and Symptoms Yours Needs Help

Kelsey_Kunik_graciouslynourished1graciouslynourished/Instagram

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

Holding Onto Extra Weight

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

Fatigue

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

Constipation

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

Always Feeling Cold

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

Hormone Imbalances

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

The Answer: Feed Your Body with Nutrients

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

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

tara_collingwood6dietdivatara/Instagram

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

💪🔥Body Booster: If you are struggling with your metabolism, resist dieting. Instead, try and take a more balanced approach to nutrition, allowing it to reset.

The most common sign you are consuming too many calories is that you are gaining weight. But did you know that your body might be sending you signs that you aren’t taking in enough? Lexi Wright is a metabolism, menopause, and fat loss coach whose main goal is helping “women 40+ reset their metabolism, lose weight, improve energy.” In a new post, she explains that not eating enough can have an impact on your health. “I see this with women in their 40s and 50s all the time. They are on the eat less workout plan for losing weight, and it's not working for them,” she writes. “Our bodies are smart, and we need a certain amount of calories for our actual normal body functions.” Here are key signs you aren’t consuming enough calories.

You Are Always Cold

Are you often feeling cold? It may be because your caloric intake is too low. “Your body is smart and its common response to inadequate calories is to conserve energy to maintain your body core temperature,” she writes.

You Are Always Tired

If “you lack energy and feel exhausted all day,” it could have to do with your food intake. “Too low of calories and your body will not have the energy to fuel itself for daily activities,” she writes.

Another sign? “You are constantly in a binge restrict cycle because the calories are so low and you trigger feelings of deprivation which leads to cravings and binging,” says Lexi.

Hair Loss

Losing hair is another sign you aren’t consuming enough calories. “Low calories can deprive your body of the nutrients it needs for a lot of body functions including hair growth and maintenance,” says Lexi.

Constant Hunger

“You are hungry all the DAMN time even though you are eating a good amount of protein and fibre to fill you up,” is the fifth sign you aren’t getting enough calories. “Your body is very smart and is telling you something!” she says.

You Lose Weight Fast

A more obvious sign? “You drop weight fast. More than 0.5% of your body weight every week,” she writes. “Rapid weight loss can indicate an excessively low calorie intake, which may compromise your overall health and metabolism.”

Irregular Periods

If “your period goes bye bye or is irregular,” it may be a sign you aren’t eating enough. “When our bodies are under stress it’s defense mechanism is to shut down things that take a lot of energy and having a baby is one of those!” she writes.

Mood Swings

Dark-haired girl covers her face with handsShutterstock

If you are experiencing mood swings “and can’t get motivated,” you probably aren’t consuming enough calories. “Low calories can impact your mood and mental well-being, leading to irritability, mood swings, and overall motivation,” she writes.

You Can’t Build Muscle

A woman rubbing her upper arm at the fitness gymShutterstock

“You have been lifting weights and you are not getting any stronger,” is another clear sign. “Muscle is expensive calorie wise to keep and build. When we don’t have the calories to fuel workouts and muscle growth this is one of the first things that go,” she writes.

Constipation

The last sign you aren’t consuming enough calories? “You are constipated all the time,” she writes. “Lack of calories usually means lack of nutrients including fibre. Proper digestion is how we clear out all the ‘STUFF’ having a bowel movement at least once a day is essential to overall health,” she maintains.

💪🔥Body Booster: Just as eating too many calories per day can negatively impact your overall health, not eating enough can too. Try and hit your daily caloric intake goals to maximize health.

We've consulted with our team of licensed nutritionists and dietitians to bring you informed recommendations for food products, health aids and nutritional goods to safely and successfully guide you toward making better diet and nutrition choices. We strive to only recommend products that adhere to our philosophy of eating better while still enjoying what you eat.

Many of us have stood in front of the mirror, promising ourselves that this time, we'll finally shed those extra pounds - and fast. However, the desire for quick results often leads to mistakes that can be counterproductive or even harmful. Read on to learn common pitfalls to avoid when attempting rapid weight loss, with insights from fitness and nutrition experts.

Setting Unrealistic Goals

Hand with Pencil making goals list to lose weightShutterstock

One of the biggest mistakes is setting unrealistic goals, such as aiming to lose 5 percent body fat in just two weeks. Blanca Garcia, RDN, cautions, "A 5% body fat loss in two weeks is not a recommendation I would make. The healthier, more achievable goal is to make lifestyle changes that are small but doable."

Falling for Crash Diets

Crash diets or extreme calorie restriction can be tempting for quick results, but they're often counterproductive. Fitness expert Jillian Michaelswarns, "When you starve the body, you're telling your body, 'Oh my god, food is really scarce.' This can lead to metabolic damage and the dreaded yo-yo effect."

Neglecting Exercise

Contrary to popular belief, exercise plays a crucial role in weight loss. Michaels advises, "If you're trying to lose weight, it's like 80% exercise because you can't starve it off." Neglecting physical activity can significantly slow down your weight loss progress.

Ignoring Macronutrient Balance

Focusing solely on calorie reduction without considering macronutrient balance can lead to nutrient deficiencies and muscle loss. It's important to maintain a balanced diet that includes adequate protein, healthy fats, and complex carbohydrates.

Overexercising

While exercise is crucial, overdoing it can be counterproductive. Garcia advises, "Setting overly ambitious goals with physical activity can lead to injury, but also can have feelings of despair if the goals are not met."

Neglecting Sleep and Hydration

Insomnia and social media addiction concept. Young woman uses smartphone while lying in bed at night, tonedShutterstock

Many people underestimate the importance of sleep and hydration in weight loss. Lack of sleep can disrupt hormones related to appetite, increasing the likelihood of overeating. Similarly, dehydration can slow down metabolism and lead to overeating due to thirst being mistaken for hunger.

Relying Solely on the Scale

Focusing only on the number on the scale can be misleading and demotivating. Catherine Gervacio, registered dietitian, suggests, "Consider factors like energy levels, mood, sleep quality, and overall health as important markers of success."

Overlooking Muscle Mass

Rapid weight loss often leads to loss of muscle mass along with fat. Gervacio advises, "Focus on your proteins and make sure you get the right amount and kind. Aim for a diet that includes a variety of nutrient-dense foods like fruits, vegetables, lean proteins, whole grains, and healthy fats."

Expecting Immediate Results

Expecting dramatic results in a short time can lead to disappointment and giving up. Garcia reminds us, "Weight loss that is sustainable for the long term requires changes that are lifelong and can only be sustained if those changes are something a person can actually do."

Ignoring Professional Guidance

Attempting rapid weight loss without professional guidance can be risky. Garcia emphasizes, "Rapid weight loss can be achieved in a safe and sustainable manner through direct work with a doctor and registered dietitian."

While the desire for quick weight loss is understandable, it's crucial to approach it healthily and sustainably. Avoid these common mistakes and focus on long-term lifestyle changes for the best results. As Gervacio says, "Understand that achieving long-term health and sustainable changes takes time. Be patient with yourself, and avoid self-criticism. Focus on progress rather than perfection!"

Are you trying to lose weight but aren’t really getting anywhere? According to experts, you might be going about your weight loss journey the wrong way. In fact, even some of the top diet and fitness experts have made weight loss mistakes themselves. Body Network spoke to a few trainers and nutritionists and asked them about the biggest missteps they took on their fitness journeys.

1. Going Overboard with Calorie Counting

While it is good to keep tabs on your food consumption, Risa Sheppard, Master Pilates trainer, creator of The Sheppard Method, advises not to go overboard. “Counting every calorie of every piece of food,” is one of the mistakes she made. “It became time consuming and frustrating.”

2. Starving Your Body of Carbs

Mr. America Jason Kozma, a personal trainer in Los Angeles, reveals the biggest mistake he made while preparing for a bodybuilding competition. “I had gotten too heavy bulking up to add more muscle mass,” he explains. He spent four months dieting for a spring show “and still didn’t get in shape.” After a short break he reset his goal to a fall show and dove headlong into his diet. “I was using an extremely low carb approach as I felt I had too much fat yet to burn. What I actually did was I starved my muscles of carbohydrates for so long that at the end my body couldn’t assimilate carbohydrates and I couldn’t ‘pump u’ for the show,” he continues. “My body fat measured lower than ever for this show but I didn’t look as good as I had a year and a half prior at a higher body fat level. The net result was that I lost muscle using this approach: I was actually smaller and lighter than I was before the ‘bulk up.’” Note: He still won the show!

3. Doing Too Much Cardio

Diet and fitness expert Adita Yrizarry-Lang, ISCA, NASM, ACE, AFAA, reveals that one of the biggest mistakes she made was doing too much cardio. “When I first started in fitness, this was the prescription…do a lot of cardio. The reality is that you burn more calories when you have muscle on your body, combining weights with cardio is the right way to do it,” she says.

4. Not Looking at Serving Size on Packages

Yrizarry-Lang claims that another mistake is only looking at calories on a package, and not the serving size. “We were mesmerized by the lo-cal labeling on a package,” she says. “Unfortunately, we never looked at the serving size and then came to realize we were ingesting too many calories at a time.”

5. Falling Victim to Low Fat, Highly Processed Foods

Just because something is low-fat doesn’t make it healthy. Yrizarry-Lang says that some people consume “too many processed carbs, because they are low fat.” While this might be okay for runners, going for 10 to 20 mile runs, “those carbs convert to fat,” for most of us.

6. Daily Weigh-Ins

Weighing oneself every single day is another mistake, says Sheppard. “It can be discouraging,” she explains. “Try to weigh yourself less and pay more attention to how your clothes are fitting. Remember muscle weighs more fat so if you are on an intense exercise regime the muscle you gain will trim in less but may not show on the scale.”

7. Crash Diets

If a diet seems too good to be true, it probably is. “The all-time worst” mistake people make is going on crash diets. Why? You might “lose weight at the moment” but you will “gain it back with a few extra pounds,” says Yrizarry-Lang. “This slows down the metabolism and makes it even harder to lose weight at a later date.”

8. Focusing on Exercise for Weight Loss

One of the biggest mistakes people make is “thinking more exercise will cause them to lose weight,” says Sheppard. “80 percent is dieting and 20 percent is exercise,” she reminds.

9. Falling Victim to “Get Thin Fast” Scams

Sheppard strongly advises against any products or diet that claim to help with rapid weight loss. “Do not succumb to quick weight loss scams or dangerous pills. Remember Rome wasn’t built in a day and neither is weight loss,” she says.

10. Comparing Yourself to Others

Remember that your fitness journey is your own and “comparing yourself to other people” will “only add to your stress and discouragement,” says Sheppard. “We are all built differently with different bone structure and hereditary genes. Love who you are inside and it will reflect on your outside.”

💪🔥Body Booster: Beware of low-fat, processed foods. Unless you run for 20 miles a day, you should probably pass on a highly processed energy bar – those carbs might convert to fat unless you are working them off.

Are you trying to lose weight, doing everything you think you should be, but the number on the scale won’t budge? According to an expert, it’s possible that you are doing the wrong things and don’t even know it. Laura Denys is a fitness and nutrition coach with over 1.3 million Instagram followers. In a new social media post, she discusses her weight loss journey and admits that she couldn’t lose weight until she changed her approach to diet and fitness. Here are the 5 things she stopped doing to lose 44 pounds.


Stop Following Diets

The cabbage soup diet, keto, cleanses or other trendy diets may seem like a quick fix for weight loss. However, if you are seriously restricting yourself and going on crash diets to lose weight, you could be getting in your own way, according to Laura. “Stop following diets,” she says. “Go to get out of that ‘all or nothing’ mindset.”

Stop Skipping Meals

It can be tempting to miss a meal to cut calories from your day, but Laura doesn’t recommend it because oftentimes, it will lead to you eating more later in the day. “Stop skipping meals, used to think going all day without eating was gonna help me get results but it only caused me to binge eat at midnight,” she says.

Stop Overdoing It with Exercise

Also, don’t go too hard with exercise. “Stop exhausting yourself and learn to rest. I used to do hours on the stair master now I only walk/run for my cardio,” she says.

Stop Restricting Yourself

And, you don’t have to go to extremes with your diet. “Stop restricting yourself and had to learn portion control,” she says. You can even enjoy sweet treats. “I learned to enjoy dessert in moderation,” she says.

Stop Setting Weight Loss Goals

And her final tip might come as a surprise. “Stop having goals,” she says. “Think that you could lose 2-5lbs a week consistently and would put so much pressure on myself. But as a female your weight changes daily so some weeks l’d lose 2lbs and than gain a lb the next week.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

Are you over 40 and struggling to lose weight? Julie Clouse is a social media influencer and fitness and macros expert who tries to “inspire others to be the best version of themselves.” In a new social media post she reveals a few of the habits all the fittest women she knows share. “Not to be dramatic but…There is no secret. The fittest women I know in their 40s have these 6 things in common. They ALL DO THIS!!!” she writes.

Strength Training

The first habit they share? “They prioritize strength training,” she says. “Fittest women in their 40s consistently lift heavy weights, focusing on progressive overload to build muscle and maintain strength.”

Healthy Diet

The next thing they have in common is a healthy diet. “They eat for their goals,” she explains. “They track their macros, prioritize protein (about 1g per pound of body weight), and fuel their bodies with balanced nutrition instead of following fad diets.”

Daily Activity

Another thing they do? “They stay active daily,” she says. “They prioritize NEAT (non-exercise activity thermogenesis) by walking, staying active, and avoiding a sedentary lifestyle, aiming for at least 8-10k steps a day.”

Stress Management

They also understand the importance of mental health and self-care. “They manage stress and recovery,” she writes. “They take rest days, prioritize sleep, and understand that recovery is just as important as workouts. Many practice mindfulness or stress management techniques.”

Patience and Discipline

The fifth habit they share? “They embrace patience and discipline,” she says. “They know results take time and stay disciplined even when progress feels slow.”

Consistency

And what is the most significant piece that ties this all together? “They are CONSISTENT,” she says. “No matter how busy life gets, they show up for themselves day after day. They don’t rely on motivation; they rely on habits they’ve built over time.”

Bonus Tips: Just Start

She also offers some bonus tips. “Just start,” she suggests. “Instead of getting overwhelmed about 6 things you feel like you need to change. Pick 1 start there.”

Don’t Focus on Perfection

“You do NOT have to be perfect. If you’ve been here long enough, I share how to incorporate a sustainable life style with your busy lives and families,” she adds.

Stay the Trail

Next, just keep going. “Yes, it will be hard at first. Yes, there will be days you’re wondering if you’re making progress. Stay the trail. This is for the long term. This is for longevity with your kids and spouses. This is for YOU!” she says.

Take One Hour for Yourself

She also stresses the importance of taking care of yourself and not feeling guilty for it. “Self care is not selfish. You deserve 1 hour to yourself,” she says.

Focus on Losing One Pound a Week

Finally, aim for one pound a week and celebrate it. “Losing 1lb a week is a BIG DEAL!! Imagine if you gained a lb a week. Give yourself grace. The slow way is the fast way for the long term,” she says. And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.
