[QUOTE="Champ"] I thought it was 2500 for a woman, 3500 for a man in a sedentary job and 4500 for a man doing physical work. Less than 1000 cals a day is a starvation diet. I simply don't believe you were down at those levels, nor that you're on 1750 now.[/QUOTE] Are you under stress? Have a look here [URL="http://www.freedieting.com/tools/calorie_calculator.htm"]www.freedieting.com/tools/calorie_calculator.htm[/URL] The numbers are right. 2500kCal is for "normal existence", if you are training you will need much more. I'm a diabetic with a dodgy pancreas and highly insulin resistant. Somewhat desk based. 1000 calories certainly isn't starvation for me. I only lost 4kg in 2 months at that rate, bed bound. And I certainly don't eat as much as 2000 at the mo and it seems to be stable.
