Eat These Foods to Lose Weight

A negative-calorie food is a food that uses more food energy to digest than iis contained in the food. The thermic effect is the caloric usage of digesting the food. It would be more than the energy content contained in the food or beverage. This effect is scientifically called specific dynamic action.

One negative-calorie beverage is ice water. It has no calories but the body has to expend energy to raise the liquid to body temperature.

Some foods that are considered to be negative-calorie foods are the following:

hard boiled eggs
celery
grapefruit
lemon
lime
apples
lettuce
broccoli
cabbage
other low-calorie fruits and vegetables

Although these may not be true negative calorie foods, they are low in calories, healthy, and with roughage.
