5 Foods With Negative Calories

 Negative calory foods
negative-calorie food would be a food that required more food energy to be digested than it provided.
That is, its thermic effect – the caloric "cost" of digesting the food – would be greater than its food energy content. The thermic effect is scientifically called specific dynamic action. While this concept is popular in dieting guides, there is no scientific evidence supporting the idea that any food is a negative-calorie food.
Some soft drinks are erroneously advertised as having "negative calories". The only truly negative-calorie beverage is ice water, which has no calories but requires the body to expend a very small amount of energy to raise the liquid to body temperature.

5 Negative-Calory Foods

1. Celery
One cup of celery contains less than 20 calories. It's rich in fiber, full of water and can even help reduce the risk of ovarian cancer. By the time you prepare, wash, eat and digest it, the 20 calories — and then some — will be long gone.

2. Cucumbers
Cucumbers have 15 calories per cup and pickles have just 17 (assuming there's no sugar added). Make sure to eat the skin since that contains all the fiber. The rest of the cucumber is mostly water and lacks vital vitamins and nutrients. Still, at so few calories, you can consume as many as you'd like guilt-free.

3. Asparagus
Asparagus, like grapefruit, flushes water out of the body by acting as a diuretic. It contains a chemical that helps break down fat cells and can reduce body fat overall. Not only does asparagus act as a fat repellant, it also is used for anti-aging purposes, protects against cancer and can reduce pain and inflammation.

4. Apples
Apples are filling, healthy and will satisfy your sweet-tooth craving. Apples typically contain 100 calories for a medium-sized one and take 120 to digest. Apples also contain vitamin C, plenty of antioxidants and can help lower cholesterol.

5. Lemons
Lemons cleanse the body and can add flavor to a rather dull meal. Put some in warm water and drink in the morning to jump-start your metabolism for the day. Lemons also promote immunity and fight infections, with research confirming they even protect against a variety of poisons.
