one good thing about being 300+ pounds though is the more you weigh, the more calories you burn, and the easier it is to lose weight quickly. For instance if you were say, 35 years old, 5'10 350 lbs, your basal metabolic rate (the energy your burn just being alive) would be approximately 2500 calories a day. Your total daily energy expenditure would be roughly about 3500 calories, meaning that's how much you'd need to sustain yourself if you were walking around, working and going about your day and whatever; no exercise. That means if you cut yourself down to 2000 calories a day, even if you slept all day or were in a coma, you'd be losing about a pound every 5 days. If you get out of bed everyday and go about your day, you'd be losing 3 pounds per week; without any exercise at all. You'd be hungry, but that's what weight loss is, being hungry and using your fat stores for energy. We've evolved into this over hundreds of thousands / millions of years, when we had to hunt and gather food, and since food wasn't a guarantee we had to evolve a way to pack that extra food when it was abundant, then use it when it was scarce; fat. We're hardwired to eat and eat, and since we're privileged to have an unlimited wealth of food in front of us every day, we need to control ourselves. Count calories
