Certain foods burn more calories during digestion than what they have
These are foods high in fiber and have a low glycemic index
One of the most popular food fads that has grabbed everyone’s attention in recent times is the notion of ‘negative calorie’ foods. According to this theory, you can have as much of these foods as you like without any weight gain, and that's because digesting these foods takes up more calories than what they inherently contain. Hence, nullifying the calorie addition. This does not mean that these foods do not contain calories but only the fact that your body ends up burning more calories than what you consume. A win-win situation. Isn't it?
Renowned Bangalore-based Nutritionist, Dr. Anju Sood, explains, “We classify calories in two categories. Empty calories and negative calories. Empty calories are the ones, which when consumed generate immense amount of calories (main sources being fast food and refined sugar). These contain no nutritional value. The other, negative calories, come from foods that are nutritious and low on calories. They are great to be added to your diet if you want to lose weight as your body does require bare minimum calories to generate energy and sustain."
"High fiber foods or those that have a low glycemic index can be called as negative calorie foods. High fiber foods fulfill two purposes. Our body takes longer to flush out fiber from the body, hence they stay in the body and delay hunger. And secondly, they release sugar slowly and so, the incidence of it turning into fat is low," says Dr. Sood. Rich in nutrition and extremely low on calories, load your plate with these delicious foods.
