15 Foods To Help You Lose

11. Vinegar. It's a great filler-upper. In a Swedish study, researchers found that people who ate bread dipped in vinegar felt fuller than those who had their slices plain. The probable reason: Acetic acid in the vinegar may slow the passage of food from the stomach into the small intestine, so your tummy stays full longer. Vinegar can also short-circuit the swift blood-sugar rise that occurs after you eat refined carbs such as white bread, cookies, and crackers.

12. Tofu. It seems too light to be filling, but a study at Louisiana State University showed that tofu does the job. Researchers tested it against chicken as a pre-meal appetizer for 42 overweight women-and the participants who had tofu ate less food during the meal. The secret: Tofu is an appetite-quashing protein.

13. Nuts. Yes, they are fattening: A handful of peanuts is about 165 calories. But research shows that people who snack on nuts tend to be slimmer than those who don't. A study from Purdue University found that when a group of 15 normal-weight people added about 500 calories worth of peanuts to their regular diet, they consumed less at subsequent meals. The participants also revved up their resting metabolism by 11 percent, which means they burned more calories even when relaxing. Health bonus: Walnuts contain omega-3 fatty acids. And researchers at Loma Linda University recently found that eating 10 to 20 whole pecans daily can reduce heart disease risks.

14. High-fiber cereal. Studies show that you can curb your appetite by eating a bowl for breakfast. But how well does it really work? Researchers at the VA Medical Center and the University of Minnesota in Minneapolis tested the theory against the ultimate diet challenge: the buffet table. They gave 14 volunteers one of five cereals before sending them out to the smorgasbord. Those who'd had the highest-fiber cereal ate less than those who didn't have as much fiber in the morning. Try General Mills Fiber One (14 grams per serving) or Kellogg's All Bran With Extra Fiber (13 grams per serving).

15. Hot red pepper. Eating a bowl of spicy chili regularly can help you lose weight. In a Japanese study, 13 women who ate breakfast foods with red pepper (think southwestern omelet) ate less than they normally did at lunch. The magic ingredient may be capsaicin, which helps suppress appetite.
