I didn't want to hijack the weight loss thread, so I'm asking this separately.
I was recently appalled to discover that I weight 270 lbs. That got me thinking about crash diets. (Just thinking, not doing!)
I've always heard that a person can live about 30 days without eating. I've also heard that one must burn 3,500 calories in order to lose one pound of fat. Fine. If a guy like me needs about 2,400 calories a day in order to maintain his weight, and I eat nothing at all, thenassuming that my metabolism remains constant, which I know it wouldn'tin 30 days I should lose 72,000 calories' worth of weight, or about 20.5 pounds.
THE MATH: 2,400 cal/day X 30 days / 3,500 cal/lb
Really!? If I ate nothing at all for a whole month, I would lose only 20.5 lbs.??? By the same figuring, and supposing my starved-to-death weight is about 150 lbs., then it would take me nearly five months to starve to death!
That can not be right. Can someone please tell me what I'm missing?
