Green Beans

Filling up on green beans, and other high-fiber foods, can help you prevent weight gain or even promote weight loss—without dieting—suggests new research in The Journal of Nutrition.

Researchers found that women who increased their fiber intake generally lost weight while women who decreased the fiber in their diets gained. The scientists boiled the findings into a single weight-loss formula: boosting fiber by 8 grams for every 1,000 calories consumed resulted in losing about 4 1/2 pounds over the course of the study. Try it for yourself. If you’re consuming 2,000 calories per day, aim to increase your fiber by 16 grams. Raspberries, chickpeas and strawberries can also help you get your fill.
