You must be mistaken in your numbers. There's no way you could eat only 1200 calories a day -- about half a normal calorie intake -- and not lose significantly. And 600-800 is starvation. You must be eating a lot more than you think you are.
Diet and weight related calorie numbers, as Dr. Weil mentioned, are rough and approximate but your report of eating so little while exercising and not losing weight is highly implausible. I suggest you are grossly underestimating your caloric intake.
Everyone is not the same. The 3500 cal per pound number is a rough guideline and there is significant variation between individuals. But the numbers you give are not reasonable. I am the same height as you and weigh about 165. (btw, your weight naturally fluctuates by 2 or 3 pounds from day to day and throughout the day depending on degree of hydration, glycogen storage, GI contents, etc..). I count the calories I consume and again, these types of numbers are not precise, but if I ate 1200 calories a day I'd be hungry all the time and would shrink down to nothing pretty fast. As Dr. Weil said, you are not really overweight and should be concentrating on body composition (proportion of muscle to fat), not the number on the bathroom scale. I am curious, though, how you manage to be so far off in your estimate of your caloric intake. I must point out I am assuming you don't have some sort of serious metabolic or GI disorder which prevents you from absorbing the calories you swallow.View Thread
"But what's most important is that you make the choice right now between settling for "normal" aging, or getting younger in the upcoming years."
That's misleading. I am 58 and have been running and lifting weights for decades. I am in good shape for 58. But I am not getting younger. In fact, I am fully 40 years older than I was 40 years ago. And I'm betting you that in another 40, I will be dead.View Thread
