You would have heard the term “Calories” frequently. If not, a calorie is a unit to measure the energy expenditure by our body and the energy stored when we eat. So what are negative calorie food items? No, they are not zero-calorie foods. Theoretically, more energy is required in digesting these items than the energy they provide. Why? Because these are whole foods, vegetables, and fruits with a high water content which are rich in dietary fiber. Confused? Consider 50 grams of a cucumber which contains around 8 calories.
If the body spends more than 8 calories in digesting this, it comes under negative-calorie foods. The dietary fiber is hard to digest, so our body typically spends more energy in breaking them down thus spending more calories.
So what are the foods which are rich in water and dietary fiber?
- Helps with weight-loss
- Improves digestion and prevents constipation
- May lower the risk of diabetes
Incorporating these foods into your everyday diet routine becomes essential if your plan is to lose weight. However, it is neither sustainable nor advisable to plan a diet only with these foods.
