10 Zero Calorie Foods

10 Zero Calorie Foods

“Stop before your tummy is full!”

You’ve probably heard this golden diet mantra countless times and followed it too. But it gets annoying to always feel dissatisfied at the end of a meal. Wouldn’t it be nice to, sometimes, to stuff yourself till you can’t eat anymore, that too without any guilt?

You can, if you snack on ‘zero-calorie’ or ‘negative calorie’ foods. They are foods that contain some calories, but such a small number that the energy spent eating or digesting them nullifies the calories consumed.

So, go ahead and binge on:
