A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
Once you’ve completed the 3 Day Military Diet plan, it’s best if you limit yourself to 1500 calories a day for the next 4 days. Other dieters follow the military diet 4 days off rule, which means that after 4 days of following a 1500 calorie diet, they do the 3 Day Military Diet again. So, what does a 1500 calorie diet look like? Here are some ideas for how you can plan your meals for your 4 days off:
Weight gain has been associated with excessive consumption of fats, (added) sugars, refined carbohydrates in general, and alcohol consumption.[citation needed] Depression, stress or boredom may also contribute to weight increase,[5] and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night's sleep lost more than twice as much fat as sleep-deprived dieters.[6][7]

The ketogenic diet—also known as "keto"—has become the latest big thing in weight-loss plans, touted recently by celebs like Jenna Jameson, Mama June, and Halle Berry. The diet involves cutting way back on carbohydrates, to 50 grams a day or less, to help the body achieve a state of ketosis, in which it has to burn fat (rather than sugar) for energy.
If what you're attracted to is the idea of a quick, three day challenge, Palinski-Wade has other ideas. "Challenge yourself to eat a minimum of 30 grams of fiber per day and at least 5 servings of fruits and vegetables. This would still reduce calorie intake while providing your body with nutrients that promote health all while allowing you to develop eating habits that can actually lead to sustained weight loss." If it's the idea of inermittent fasting that you like, there are other ways to try that, too.
We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low-carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again.
3. Doing Bicycles not only help to melt belly fat it also works on the muscles of your upper body. For this you have to lie on your back and raise your legs at 90 degree, then bend your legs to 90 degree and hold it. Keep your hands under your head and slowly raise your head and shoulder off the ground. Now with a fast movement bring your right elbow to your left knee and extend your right leg in the front. You have to switch sides fast to create the cycling effect. Use your core muscles to keep your head and shoulder above the ground throughout the exercise. Do 20 repetitions and add 10 as you become stronger.
Variations on the Johns Hopkins protocol are common. The initiation can be performed using outpatient clinics rather than requiring a stay in hospital. Often there is no initial fast (fasting increases the risk of acidosis and hypoglycaemia and weight loss). Rather than increasing meal sizes over the three-day initiation, some institutions maintain meal size but alter the ketogenic ratio from 2:1 to 4:1.[9]

The 2003 research indicated that exercise is a top weapon against visceral fat, backed up by a 2011 study which found that aerobic exercise is basically a magic bullet. Aerobic exercise is known to most people as cardio — activities such as running and cycling, as opposed to resistance training (where you lift heavy stuff around). While participants in the study worked fairly hard (jogging 20km per week at a high intensity), the researchers said lower-intensity but longer workouts should have similar benefits.
Based on calories, you need to cut out or burn 3500 calories to lose 1 pound . Multiply that by 10 pounds, and you’re talking about cutting out 35,000 calories in a week. That’s quite a bit! If we consider your eating habits, most people consume about 2000 to 2500 calories every day. On the Military Diet, you’re cutting back to about 1200 calories a day on the 3 Day diet, and probably around 1500-1700 calories on the 4 days off. That means just in calorie consumption, you’re cutting out about 1000 per day during the restricted portion of the diet.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).
Diets to promote weight loss can be categorized as: low-fat, low-carbohydrate, low-calorie, very low calorie and more recently flexible dieting.[1] A meta-analysis of six randomized controlled trials found no difference between low-calorie, low-carbohydrate, and low-fat diets, with a 2–4 kilogram weight loss over 12–18 months in all studies.[1] At two years, all calorie-reduced diet types cause equal weight loss irrespective of the macronutrients emphasized.[2] In general, the most effective diet is any which reduces calorie consumption.[3]
Craving something sweet? Instead of fattening cookies or cake, reach for fresh figs. Thanks to their dense consistency and high amount of filling fiber, they can slow the release of sugar into your blood. Pair with ricotta cheese, melons, and prosciutto to make a satisfying fruit salad, or use as a topping on whole-wheat pizza with crumbled feta and walnuts.
"Eating too much sugar, high doses of unhealthy oils and fats, stress, and lack of exercise can all cause the injury that leads to inflammation," explains Pines. So if you're doing those things often, it's going to ramp up the amount of time your body is inflamed—just like when you get a nasty bruise from repeatedly hitting the same area of your body. Pines says the biggest clue that you might be having a problem is, well, your belly. "If you've been 'dieting' and you still have that belly bulge, look at nutrition labels to see how much sugar or sodium is sneaking in," she suggests. She also suggests adding inflammation-busting foods into your diet, like a cup of blueberries in oatmeal, or a half-cup of edamame with lunch. 
High blood sugar levels coupled with high blood ketones, on the other hand, will mean that you have a pathologically low level of insulin – something non-diabetics do not suffer from. This can lead to ketoacidosis – a potentially life-threatening condition. If this happens, you’ll need to inject more insulin; if you’re at all unsure of what to do, contact a medical professional. Coveting really high blood ketones for weight control is not worth the risk for type 1 diabetics.
Get the idea? You need to include lots of fruit and vegetables in your diet. This really helps you feel full, without packing in the calories. As you can see in these two options, you can still add a few extra snacks or calories if you still feel hungry at meal or snack-time. You can always check your food’s calories by using one of the various calorie calculators available online such as the one offered by WebMD. Also notice that the only included drink is coffee. Avoid sugary drinks, alcohol and soda, as these will add a lot of calories. Instead, drink plenty of water or herbal tea. If you find plain water too boring to drink- you can add a bit of lemon or try one of the many cucumber water recipes available in this post.

Pinners, bloggers and YouTube vlogs are driving this trend forward with viral before-and-after pictures showcasing impressive (and often hard to believe) changes. Devotees of the diet consume 1,100 to 1,400 calories a day in the form of so-called “fat-burning” food combinations like hot dogs and bananas, and tuna and toast. (Yes, we said hot dogs.) It’s a one-size-fits-all plan, so athletic men and women are going to dine on the same grub as their more sedentary peers. But is this really a healthy way to lose weight? We got to the bottom of this much-talked-about plan.
Early studies reported high success rates: in one study in 1925, 60% of patients became seizure-free, and another 35% of patients had a 50% reduction in seizure frequency. These studies generally examined a cohort of patients recently treated by the physician (what is known as a retrospective study) and selected patients who had successfully maintained the dietary restrictions. However, these studies are difficult to compare to modern trials. One reason is that these older trials suffered from selection bias, as they excluded patients who were unable to start or maintain the diet and thereby selected from patients who would generate better results. In an attempt to control for this bias, modern study design prefers a prospective cohort (the patients in the study are chosen before therapy begins) in which the results are presented for all patients regardless of whether they started or completed the treatment (known as intent-to-treat analysis).[18]

Exercise and diet go hand in hand: The way you eat not only influences your weight, but your diet affects your health, too. With the right foods, you can lose excess pounds and stubborn belly fat while also nourishing your body with vitamins, minerals, and antioxidants. Not to mention, you'll feel more satisfied with your meals and can make healthy choices when you're dining out because your blood sugar levels will be stable. Here are the best foods for weight loss, according to dietitians. We promise: They all taste delicious and will keep your metabolism revved up.


Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG diet is not safe for anyone, the Mayo Clinic notes. (35)

Appetite-suppressant drugs and other diet pills:"Wonder" products that permanently reduce weight do not exist. Products that promise immediate or effortless weight loss will not work in the long run. Appetite suppressants, which often contain a stimulant like caffeine or hoodia, are associated with side effects including nausea, nasal dryness, anxiety, agitation, dizziness, insomnia and elevated blood pressure. Alli reduces fat absorption; following the package directions will reduce risk of side effects, which may include oily diarrhea and anal discharge. With any product, side effects may be worse if you exceed the recommended dosage.
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
When a person goes off the ketogenic diet and regains much of their original weight, it’s often not in the same proportions, says Kizer: Instead of regaining lean muscle, you’re likely to regain fat. “Now you’re back to your starting weight, but you no longer have the muscle mass to burn the calories that you did before,” she says. “That can have lasting effects on your resting metabolic rate, and on your weight long-term.”
This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.

That’s why many health experts are concerned about people on the keto diet, especially those who try it without the guidance of a doctor or nutritionist. Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Some have even called it a “cardiologist’s nightmare.”
For the first three days, the diet consists of three distinct meal plans. For the first day, breakfast consists of half a grapefruit, a slice of whole-wheat toast with 2 tablespoons of peanut butter, and a cup of caffeinated black tea or coffee. If you can't drink it black, it's recommended you sweeten it with a natural sugar substitute, like Stevia. For lunch, have half a cup of tuna (you can buy 3 oz or 5 oz cannes of cooked tuna, or prepare it yourself), one slice of whole-wheat toast, and a second cup of black coffee or tea. Dinner is the more filling meal, consisting of 3 oz of meat, one cup of green beans, half a banana, one small apple, and one cup of vanilla ice cream for dessert.
First things first: your stomach is made up of good and bad bacteria, which scientists like to call microbiota or gut flora. And it's important that you keep it in check, as if you were keeping a seesaw level. "Microbiota is considered the body's garden, and it has a controlling influence over a lot of important bodily functions, including metabolism," says Gerry Mullin, M.D., author of The Gut Balance Revolution. Studies show that a diet full of fat and refined carbs (think white bread and potatoes) and low in fiber (fruit, vegetables, beans and oats) disrupt the balance, and the seesaw starts to tip in favor of weight retention and fat accumulation. 
Lunch on day 1 is packed with protein, fulfilling about 60% of your daily protein intake requirements just in the tuna. The tuna also contributes other vitamins including Vitamin A, B-12, B-6 and minerals including magnesium and iron. Vitamin B-12 is an important vitamin often found in fish that plays an important role in the creation of new cells. It’s also important for nerve function. (1) The bread offers carbohydrates and plenty of fiber.

As a self-described “nutrition nerd,” I couldn’t help but analyze the first three days of menus provided using my nutrient analysis software. You’ll see the daily totals at the bottom of each day, and while I can’t describe the intake as “good”, “ideal” or “healthy,” the data was slightly better than I expected. (Or perhaps, I really wasn’t sure what to expect from this very odd combination of foods!)
No. Alcoholic drinks are high in calories. Save your cocktail for when you’re off the diet, or on the 4 days off. Even when you’re not on the diet, if you’re interested in maintaining your weight, you should avoid certain types of alcohol. For example, steer clear of sugary alcoholic drinks such as long island iced teas and margaritas. The sugar adds in a lot of calories that will promote weight gain. Instead, go for a gin and tonic or vodka with soda water and lime. Red wine is also a great choice. You should also try to lay off beer if you’re hoping to maintain or lose weight. If you’re really craving a beer, go for a dark beer like Guinness which is rich in antioxidants.
Repeat after us: It’s time to start eating clean. She recommends a combination of veggies, fruit, whole grains, nuts, seeds, beans, low-fat dairy and lean protein like poultry, eggs and fish for a dose of omega-3 fatty acids. And drop the added sugar while you’re at it. “Studies show that when you have a diet rich in whole grains — and calorie-controlled — that you can reduce the belly fat,” she says. But remember to watch your portions, too. “A lot of people eat very healthy and don’t eat junk, but their portions are too large.”
For the first three days, the diet consists of three distinct meal plans. For the first day, breakfast consists of half a grapefruit, a slice of whole-wheat toast with 2 tablespoons of peanut butter, and a cup of caffeinated black tea or coffee.

So, how can you lose more than 3 pounds then? Well our bodies are more complex than simple calorie-counting would have you believe. Each person’s metabolism is different and reacts differently to the diet. Many people burn more than 2000 calories in a day, just through their regular activities, which would mean you’d lose more weight. It’s also possible that you typically consume more than 2000 calories in a day- making the effects of the diet even more dramatic.

“This warming—or cooling—beverage serves a dual purpose. Not only is it full of antioxidants and other healthy phytochemicals, but it has the benefit of slightly increasing your metabolism,” says Harris-Pincus. Sipping tea in the evening instead of snacking, or trading in your PSL for a cup of green tea will lower your calorie intake and help you burn a few extra calories. Just be sure to keep it unsweetened.
Do follow a sensible diet after the initial 3 days. Though it may be tempting, especially if the pounds are melting away, don't cycle multiple rounds of the 3 Day Military Diet back to back. Your body needs more calories and nutrition than the diet provides. You can still make progress towards weight loss goals if you keep your post 3 Day Diet plan healthy.
No shocker here: It turns out that the Military Diet isn’t quite the unique weight loss solution it’s made out to be. “This [diet concept] has been dressed up differently and brought out to dance before,” says Kimberly Gomer, R.D., director of nutrition at Pritikin Longevity Center. In other words, a restrictive three-day plan is nothing new in the health industry.
Are you trying to shed those extra kilos? The ketogenic diet is a low carb diet, moderate in protein and high in healthy fats. The primary goal of the ketogenic diet is weight loss. The diet helps to bring your body into a metabolic state which is known as the ketosis. Ketosis occurs when the body has run out of its glycogen (which is basically sugar) stores so it needs to find another source of fuel. When this occurs your liver begins to process fat into ketones which become the body's main fuel source. Some of the foods that one can enjoy on a keto diet are avocado, cheese, sour cream, Greek yoghurt, chicken, fatty fish and full-fat milk. Just like every coin has two sides, in the similar way every diet has some pros and cons. The following article will explore some of the advantages and disadvantages of this fad diet, keto diet.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.

Here’s the hard truth—the Military Diet is the quintessential definition of a “fad diet,” and it’s an eating plan that I would not recommend or advise anyone to follow. Not only does it provide inadequate nutrients, but the diet’s food choices and food group servings do not follow the guidelines that research suggests to maintain health and prevent disease.
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[3] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:[27]
Make your own. It’s easy! From one 14-ounce can of no-salt-added cannelini beans, spoon out 2 tablespoons of beans. Puree the rest. In a medium nonstick pot, sauté 5 cloves of chopped garlic until translucent. Add 2 cups low-sodium chicken broth and 1 head of escarole, chopped, or a package of frozen chopped spinach. Simmer for about 15 minutes. Add pureed beans, red pepper flakes and black pepper, to taste, and cook 1 minute longer. Garnish with the beans you spooned out plus, if you desire, a little chopped red bell pepper. Refrigerate or freeze what you don’t eat for easy soup prep for a future lunch or dinner.

“This green veggie is a weight loss superstar and easy to incorporate into almost anything you're eating like smoothies, salads, and wraps. Spinach is low in carbs and high in fiber,” says Michalcyzk. You can eat a large volume of it for few calories, and the nutritional value hits all the marks to ensure you meet your daily requirements for weight loss.

The ketogenic diet achieved national media exposure in the US in October 1994, when NBC's Dateline television programme reported the case of Charlie Abrahams, son of Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Abrahams discovered a reference to the ketogenic diet in an epilepsy guide for parents and brought Charlie to John M. Freeman at Johns Hopkins Hospital, which had continued to offer the therapy. Under the diet, Charlie's epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research.[10] A multicentre prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published[17] in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, ...First Do No Harm, starring Meryl Streep, in which a young boy's intractable epilepsy is successfully treated by the ketogenic diet.[1]
In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.
The ketogenic diet tries to bring carbohydrates down to less than 5 percent of a person’s daily caloric intake – which means eliminating most grains, fruit, starchy vegetables, legumes and sweets. Instead, it replaces those calories with fat. That fat is turned into ketone bodies, which are an alternative energy source: besides glucose derived from carbohydrates, ketones from fat are the only fuel the brain can use.

Some athletes swear by the ketogenic diet, not just for weight loss but for improved performance in their sport, as well. But Edward Weiss, PhD, associate professor of nutrition and dietetics at Saint Louis University, doesn’t buy it. “I hear cyclists say all the time that they’re faster and better now that they’re on keto, and my first question is, 'Well, how much weight did you lose?'” he says.
A survey in 2005 of 88 paediatric neurologists in the US found that 36% regularly prescribed the diet after three or more drugs had failed; 24% occasionally prescribed the diet as a last resort; 24% had only prescribed the diet in a few rare cases; and 16% had never prescribed the diet. There are several possible explanations for this gap between evidence and clinical practice.[33] One major factor may be the lack of adequately trained dietitians, who are needed to administer a ketogenic diet programme.[30]
Control Your Environments. Another simple strategy to help cut calories is to control your environment -- everything from stocking your kitchen with lots of healthy options to choosing the right restaurants. That means avoiding the temptation by staying away from all-you-can-eat restaurants. And when it comes to parties, "eat a healthy snack before so you won't be starving, and be selective when you fill your plate at the buffet," suggests Ward. Before going back for more food, wait at least 15 minutes and have a big glass of water.
Still can't button your jeans with ease, or don't want to admit that you're keeping those maternity tops around longer than you'd like? If you're still dealing with stubborn belly fat, there may be more to it than simply hitting a plateau in the gym or losing your mojo. It turns out that what goes on inside your body—mainly your gut—plays a much bigger role than we thought. In fact, it helps determine whether food gets burned off or if it, well, stays put. Time to figure out exactly what problems may be happening on the inside, so you can love how you look on the outside.

Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a berry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
According to Paquette, the Military Diet does have one advantage over other weight loss plans: unlike other diets like Keto, which tend to eliminate entire food groups, the military diet includes a mix of protein, carbohydrates, and fats, albeit in tiny amounts. But he says the guidelines for the diet are simply too general to be considered healthy. For instance, breakfast on the first day simply lists "toast," without specifying whether it's whole-wheat or white.

Generally speaking, it also depends on your size. If you are overly obese, by simply cutting down on junk food and moving your body a bit, you may drop 10 pounds in less than a week easily without causing a health problem. However, for someone who is only slightly overweight or within the normal range wanting to slim down a bit, this is not healthy or sustainable. You may lose weight; but the pounds will creep up again when you stop the diet.
The meals shown here are "templates" that you can vary any number of ways to please your tastebuds and avoid eating the same old thing every day. Follow them and you'll get between 2,400 and 2,800 calories per day. That should provide plenty of calories for all but the most severely obese, while allowing most guys to lose fat around their middles at a steady pace. (Don't worry about hitting the numbers on the nose every time. If you exceed your fat quota during lunch, for instance, just cut back a little during dinner.)
When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
“Pistachios are a great addition to a diet aimed to help one lose weight because they're one of the lowest-fat and lowest-calorie snacks that offer the most nuts per serving (49 pistachios per 1-ounce serving) compared to cashews (18) and walnuts (14 halves),” says Shaw. Get in-shell pistachios because the leftover shells may provide a visual cue for portion control to curb intake.
"The keto diet is primarily used to help reduce the frequency of epileptic seizures in children. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don't know if it works in the long term, nor whether it's safe," warns registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital.
If the diet is a quick fix rather than one that promotes lasting lifestyle changes, this could pose a problem. In particular, extreme diets that promise big weight loss up front aren’t always sustainable — and you may end up overeating or even binge eating if you feel deprived. “Consider if the diet’s habits are ones you can continue throughout your lifetime, not just 21 or 30 days,” says Angie Asche, RD, a sports dietitian in Lincoln, Nebraska.

You may not think of them as a weight-loss food, but eggs are packed with protein, which helps curb your appetite. One study found that overweight women who ate eggs for breakfast were able to lose twice as much weight as women who started their days with bagels. And egg whites in particular are a good source of branched-chain amino acids, which help keep your metabolism running smoothly.


Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.

"Your body needs a healthy balance of exercise and rest. Doing too much prevents the body from shifting excess fat. Exercising without rest can impact our levels of the steroid hormone cortisol and cause an increase of stubborn fat stored in the belly. Not allowing your body to recover can increase the risk of injury too, so make sure you factor in rest days to your plan."
