Not in an extreme, Atkins sort of way, but having a little protein at every meal fires up your metabolism. "Your digestive system uses more energy to break it down, so you burn more calories," explains Lisa Dorfman, R.D. However, keep protein levels to between 20 and 35 percent of your diet; eating too much of it can cause kidney strain and may cause your body to store too much fat.
According to a small study published in the journal Annals of Internal Medicine, people who slept for 8.5 hours a night for two weeks lost nearly twice as much weight on average than participants who slept 5.5 hours per night, despite the fact that they followed the same diet and workout plan. That's because when you get a good night's sleep, your hunger hormones, like ghrelin and leptin, stay in check. That means you're not going to wake up with a sudden hankering for a bacon, egg, and cheese. (Start working towards your goals with Women's Health's Body Clock Diet.)
Not all fat is bad. Healthy or “good” fats can actually help to control your weight, as well as manage your moods and fight fatigue. Unsaturated fats found in avocados, nuts, seeds, soy milk, tofu, and fatty fish can help fill you up, while adding a little tasty olive oil to a plate of vegetables, for example, can make it easier to eat healthy food and improve the overall quality of your 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.)
Of course, it's not always easy to find—or afford—organic produce. But in general, conventionally grown items that you peel—avocado, grapefruit, bananas—are fine. But choose organic when buying celery, peaches, strawberries, apples, blueberries, nectarines, sweet bell peppers, spinach, kale and collard greens, cherries, potatoes, and imported grapes; they tend to have the highest levels of pesticides.
High in good bacteria, the benefits of yoghurt on gastrointestinal health have been said to provide health benefits for certain gastrointestinal conditions, including lactose intolerance, constipation, IBS, colon cancer, inflammatory bowel disease, Helicobacter pylori infection, and allergies. Look for the nutrition label and make sure no added sugar is used. Opt for Greek yoghurt varieties and use your own frozen berries and cinnamon to sweeten.

These fatty acids rocketed to fame for their ability to decrease the harmful inflammation that is associated with many chronic diseases—including obesity. Crandall is quick to point out that researchers have yet to find a cause-and-effect link—so don’t expect to pop a fish oil supplement, for example, and drop 10 pounds. But, she says, getting omega-3s from whole foods such as nuts, seeds, and fatty fish like salmon is a good way to hedge your bets. And bonus: If you’re suffering from other kinds of inflammation, that can lessen your willingness to be active, omega-3s might help there, too. Find out the fat-burning foods you should add to your diet.
When you’re cutting calories, it can be tough to make sure you’re still getting enough of all the good stuff your body runs on. “Nutrient deficiencies can stall or halt weight loss,” says Crandall. She sees lots of patients with low levels of vitamin D, for example, a nutrient that is critical to parathyroid hormone function—it helps with weight regulation. If you’re not eating a well-balanced diet, a multivitamin can be a good way to bridge those nutritional gaps and make sure you’re not missing anything that could impede weight loss or muscle building, such as calcium or iron.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
