Yes, but not always all in fat. If you typically don't drink too much water and all of a sudden start drinking 8-10 cups at least of water a day, you can lose up to 30 lbs in water weight. If you're looking to lose fat though, it is not healthy to lose that much weight in that time period unless you weigh over 300 lbs.
Starving yourself is a rediculous and extremely unhealthy way of losing weight. Your body needs vitamins and minerals in order to lose weight in a healthy way. No matter how much you eat, (to a certain extent) if you eat healthy and you excercise consistantly, you will lose weight.
Its Impossible Losing that much weight that fast would be very unhealthy.
It's not very healthy to lose weight too fast. Ok? What do you want to weigh? Take that number and multiply it by 10. That tells you how many calories you need to eat to weigh that much. Not very many calories, is it? That's the hard part about losing weight. You have to eat much less food. You've got to have lots of will-power to lose 20 pounds in two months.
