The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
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.)

The researchers explain that people who cook their own meals may simply have other good-for-you habits, like exercising more. However, they concluded that home cooks simply ate more fruits and vegetables (along with a wider variety of foods), have healthier methods of prepping their food, and splurge less on foods high in calories and sugar.

For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
2. Know your way around a cafeteria. Whether you’re eating in a dining hall or an office cafeteria, it’s important to know how to spot healthy options. Instead of reaching for fried foods, choose baked, grilled, roasted, or broiled meat and fish, along with steamed vegetables. Avoid foods covered in butter, cheese, or cream sauce, and go for fruit when you want something sweet, suggests the Academy of Nutrition and Dietetics.
Adult women require anywhere from six to eight hours of sleep every night. If you're staying up late on the regs and aren't meeting that minimum, you'll throw off your natural rhythm, which can cause your body to freak out and start overproducing hormones (including cortisol). By getting the right amount of sleep every night, your body and metabolism will stay regulated — keeping you and your tummy on point.

Tight deadlines, bills, your kids—whatever your source of stress, having too much of it may make it harder for you to drop unwanted pounds, especially from your middle. And it's not just because you tend to reach for high-fat, high-calorie fare when you're stressed, though that's part of it. It's also due to the stress hormone cortisol, which may increase the amount of fat your body clings to and enlarge your fat cells. Higher levels of cortisol have been linked to more visceral fat.
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.

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.
