Really, it shouldn’t be so difficult to figure out which eating regimen will set fire to fat while maintaining muscle. Fortunately, the International Society of Sports Nutrition just released its position paper, which combs through all existing scientific studies to report how every diet will affect your body composition. Here, we’ve pulled five of the most six-pack-friendly diets and streamlined how they’re great, as well as why they might be right (or wrong) for you—according to the hard science.
Who says you shouldn’t eat less than 1800 kcals? Under normal circumstances, the minimum is 1200 for women, 1500 for men, and height and weight have no bearing – these are what the body requires to avoid starvation. This diet is, however, for 7 days only, it is not intended as a long-term weight-loss strategy, so 6 days at less than 1500 won’t do you any harm. You don’t say how tall you are, or what you do for a living, which would also have a bearing on your long-term weight-loss plans. Good luck with it, anyway – it’s not easy
The authors wanted to compare low-fat vs. low-carb diets, but they also wanted to study genetic and physical makeups that purportedly (their word) could influence how effective each type of diet will be for people. Previous studies had suggested that a difference in a particular genetic sequence could mean that certain people will do better with a low-fat diet. Other studies had suggested that insulin sensitivity may mean that certain people will do better with a low-carb diet.
Want to lose that belly fat? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
Social conditions such as poverty, social isolation and inability to get or prepare preferred foods can cause unintentional weight loss, and this may be particularly common in older people. Nutrient intake can also be affected by culture, family and belief systems. Ill-fitting dentures and other dental or oral health problems can also affect adequacy of nutrition.
In addition to improving your health, maintaining a weight loss is likely to improve your life in other ways. For example, a study of participants in the National Weight Control RegistryExternal* found that those who had maintained a significant weight loss reported improvements in not only their physical health, but also their energy levels, physical mobility, general mood, and self-confidence.
Chronic migraines were what first inspired Amanda Tagge to start exercising. “I was hoping to find some relief from my headaches and working out did help but I realized that if I really wanted to feel better I needed to revamp my health habits overall and lose weight,” she says. The more she changed, the better her headaches got and she lost 70 pounds in the process which helped her feel even better. Focusing on all the ways her health was improving kept her going even when the scale wasn’t moving.
The DASH plan was originally developed to help treat or prevent high blood pressure (hypertension), but it may also reduce the risk of other diseases, including diabetes. It may have the additional benefit of helping you lose weight. People following the DASH plan are encouraged to reduce portion sizes and eat foods rich in blood pressure-lowering nutrients, such as potassium, calcium, and magnesium.
There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

Cons: That same study on the perks of being a keto athlete also found those same dieters had a lower exercise economy (how efficiently you use oxygen while moving). And whereas pretty much every other diet offers flexibility in the macro range, eating a few too many grams of carbs or protein will knock your body out of ketosis, so you have to be pretty committed to see the perks of this one. Lastly, the low protein count required to stay in ketosis may be holding you back here: A study analysis in Nutrition, Metabolism, and Cardiovascular Diseases found upping protein on a keto diet by just 5% tripled fat loss.
What's more trustworthy than a diet built by experts from the Mayo Clinic? Created by doctors, nutritionists, and all-star chefs, the plan has a few phases: In the first, you should lose 6 to 10 pounds in two weeks. After that, you can expect to lose 1 to 2 pounds a week until you reach your goal weight. You're also given plenty of resources and advice to help you keep the weight off.
Some women have trouble losing weight because of a hormonal problem. The thyroid gland, located in the neck, pumps out hormones that control body metabolism. If the gland's output isn't high enough, a condition known as hypothyroidism, the pounds can pile on - and stay on. If you think thyroid trouble might underlie your weight-loss difficulties, a doctor can test your hormone levels via a simple blood test. If you have a deficiency, effective treatment is available.
