BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Vitamins are important nutrients that your body needs, but they don’t have any calories. The foods that contain vitamins do have calories, but they are also packed with nutrients that your body needs.

Detailed explanation-2: -The only truly zero calorie food is water, but low calorie foods are also grouped in. Still, we view eating only zero or negative calorie foods as fad dieting nonsense similar to drinking ice cold water instead of room temperature water (which burns around 5 extra calories per glass, by the way).

Detailed explanation-3: -Vitamins, minerals and water do not provide any calories, even though they are still essential nutrients.

Detailed explanation-4: -Vitamins and Minerals Are Calorie-Free Essentially, in their purest form, isolated vitamins and minerals-like vitamin C or iron-are calorie-free.
