@mrashik, you have to figure out how many calories you burn during the day. When I am on this kind of diet I eat carbohydrates like rice, grains, beans in small quantities. My largest portion size is dedicated to vegetables because they have the minerals and lots of fiber which help my digestive and nervous system work well. I also take in saturated fats, my brain and nervous system needs that kind of fat for their insulation system...haha

I didn't know this but if a human doesn't get any fat in their diet they will die, the symptoms are called protein poisoning.

I eat sweet potatoes too, I love them <3
