9 'Keeping It Off' Superfoods
1. Green Tea
Go out of your way to indulge in a tall glass of iced green tea or a mug of hot green tea when you get the chance. Here's why: In a recent study, volunteers who drank a bottle of tea (fortified with green tea extract) every day for three months lost more body fat than another group who drank a bottle of regular oolong tea. Except for the different teas, their overall diets were similar. Researchers suspect that the catechins (helpful phytochemicals) in green tea may trigger weight loss by stimulating the body to burn calories and mildly decrease body fat.
2. Soup (broth- or tomato-based, that is)
Calorie-containing liquids generally are less filling than solid foods, but soups are the exception, says researcher Richard Mattes from Purdue University. In Mattes' study, participants were fed 300-calorie servings of various soups before eating their lunches (they could eat as much lunch as they wanted). Mattes found that the study participants tended to take in fewer total daily calories on days when they had the soup, suggesting that eating low-calorie soups (the broth- and tomato-based ones) before meals may reduce hunger and increase feelings of fullness.
Kathleen Zelman, MPH, RD, director of nutrition for WebMD, agrees that lower-calorie soups (that is, tomato- and broth-based varieties) are highly satisfying.
"If you have soup before a meal, it helps control hunger and you eat less," she says.
3. Low-Calorie Green Salads
Having a low-calorie salad -- not to be confused with salads brimming with cheese, croutons, high-fat dressings, and so on -- as a first course can help you feel fuller and reduce the calories you eat during that meal, according to a study by Rolls. She found that eating a small low-calorie salad tended to cut calories eaten at the meal by 7%, and a larger salad by 12%. But the study found the opposite is true with high-calorie salads. These increased the calories eaten during the meal by 8% for a small salad, and 17% for a larger salad.
