I have tried many times to use all the various internet calculators to determine my BMR (basal metabolic rate = how many calories I burn just resting), my maintenance calories and my losing weight calories.
I always get confused.
Let me demonstrate the results from this site.
Exhibit One - based solely on age and height.
First of all, if I have a small frame (which I have based on the "fingers overlap on the wrist" method), I should only weigh 108 pounds. I don't know how many kilos that it is but it is something ridiculous (yeah, I just worked it out and it's 49 fuckin kilos). Now aside from the fact that a 40s number is beyond my comprehension, there is a much bigger problem which will be evident when we contemplate Exhibit Two.
Smartie pants bloggers will have noticed that I actually have 109 pounds of lean body mass, so to get to 108 I would have to sacrifice huge amounts of muscle. Otherwise I need 0% body fat to come close and then ... I WOULD BE DEAD!
But back to the calories:
(A) BMR 1293
(B) BMR 1445
(A) 1730 for weight loss
(B) 1994 for weight loss
Now it appears that most days I have been eating under my BMR, but the days I eat anywhere near maintenance (free days) I blow up like a balloon.
So the conclusion of this post is the title : No wonder I'm confused!
Oh and please don't tell me that I am starving myself which is why I gain weight on 1730 calories a day. I don't subscribe to the starvation theory. If it were true, anoxerics wouldn't be able to get as underweight as they do because their bodies would 'hang on to their fat' rather than continue to lose it.
