What is the minimum amount of claories per day to survive?

Answer 1

This really depends on your size. As you can see on the side of packaged food, they are calculated based on a 2,000 calorie per day diet. If you are big/significantly above average in height/extremely muscular/very active you probably need more than this every day. If you are small/below average in height/not very active you probably need less.

The human body can, technically, go a few days without food, but if you are trying to lose weight it is a bad idea. If a person goes that long without food, especially on a regular basis, his body will go into "survival mode" and every time it gets food will store as much of it as possible. And yes, when I say store, I mean it will convert as much as it can into fat. If you asked this question to try to lose weight, eating as few calories as you can possibly survive on is not the way to go. Instead, try getting your approximately 2,000 calories a day in small meals every couple of hours. If your body knows it will get more food soon, it will not go into "survival mode", so it will store less as fat.
