While it's good to be cautious about any product that says you can eat more and weigh less, this may be true about one food: beans. Findings based upon data from a recent National Nutrition and Health Examination Survey showed that teens who eat beans regularly (3 cups per week) weigh less - about 7.3 pounds - than their peers who don't eat beans, yet they eat as much as 335 more calories each day.

Study authors contend that this is because beans, in addition to being a nutritious and low fat protein option, are high in fiber. And high fiber diets are thought to help reduce weight.

Try these tips for adding beans to your diet:

• Try a breakfast burrito: scrambled eggs, black beans, low fat cheese and salsa wrapped in a tortilla shell
• Sprinkle kidney beans on your salad or in your soup for lunch
• Make a quick dinner out of baked tortilla chips spread with low fat refried beans, low fat cheese and salsa
