The body will not just "eat itself" by burning fat. It also will begin breaking down muscle to get protein for repair work, rob calcium from bones to keep the heart beating regularly, and other metabolic issues that most people have no clue about. The body knows what it needs and it will do its best to keep things running, but working at a deficit of nutrients, it will lose the battle. If the starvation goes on long enough at one time to do massive damage, of course the person will die. If the starvation is intermittent, but long enough to do bits of damage each time, the person will still destroy their health and could be more susceptible to illnesses down the road. That's one of the major reasons why anorexia is so dangerous--over time, repeated starvation eventually destroys the heart, and young people die from heart attacks and heart disease from doing this to themselves.
The amount of time it would take to starve a 300 lb person depends on that person's rate of metabolism. Impossible for us to guess here, but the metabolism would slow down as a self-preservation measure, once the brain detects starvation, so the amount of time it would take is a dynamic variable and would change as the starvation progressed.
It takes a long time, and in the meantime, their metabolism would slow to almost nothing. This is a horrible way to lose weight. It's slow torture.
Hunger will be more intense for overweight people as they're not used to taking in no food.
And yes, it will start burning the fat.
Actually, the moment you begin feeling hungry, your body has already started eating itself. However, a fat person won't last much longer than a regular person. They will starve to death fat. Your body can burn the fat for energy, but it is a slow process to convert it to something useful, too slow for the body to be able to run on stored fat alone.
without food at all probably a few weeks or so. without water a few days. once all the fat is used up, the muscle will begin to break down the muscle and you'll be looking like an ethiopian kid on tv in no time.
The longer you starve yourself the more your body will shut itself down or put into hibernation mode. Your body will think that it is in a time of famine and will protect itself and not eat away the fat to stay alive.
Short term it might work but I dont think it will work so well in the long term.
Body fat, while it contains some nutrients the body can use, doesn't contain the complete multitude of chemicals the body needs to function. If an overweight person simply doesn't eat, they will become dehydrated as their blood becomes more and more saturated with waste chemicals from their body fat being used up, which causes the water in their tissue to move into the bloodstream. Quickly, their liver and kidneys will burn out from having to filter all the excess waste. But the first thing to get them will be the total lack of energy from not taking in new food. Acid levels in the body will rise, after about a week anda half, they will likely die a painful, horrible death.
Great post! I totally understand how you feel. I'm also trying to lose weight and I found this great product which is working for me (it's all 100% natural - a colon cleanse that was really gentle on my body. I feel so good and I lost 15 pounds). You can check the website at

It doesn't matter how much you weigh, when you begin starving yourself you are an anorexic, which has serious health risks invovled. Also, for the rest of your life your body will be in "starvation mode" and not only will you gain all of the weight back you will probably gain more than you had to begin with. It's just not a good idea, take it from someone who has been there
Your body would eat its fat storage first....The only time your body actually starts eating its muscles is when it has nothing else left to give it energy. Then your muscles, including your heart, will start to be consumed.
