Hatshy [7]
Hello!

<span>True or False? Liquid protein diets are a safe way to lose weight permanently.
I guess it would be safe, as long as you don't use protein powder. Only things like carne, nuts, bananas, ect,.
But if you are talking about protein powder, I would believe its not safe.

Enjoy.

Aerobic respiration refers to the use of oxygen by the body's cells to convert carbohydrates, amino acids and fats into energy while Anaerobic respiration releases energy by doing the same only it does so without oxygen.

Anaerobic respiration usually happens when the body is engaged in an activity that needs more oxygen than the lungs can supply.

These two energy sources usually work together to supply the body with enough energy however, the amount that each gives depends on the activity being done.
