RE: Re: Overeating increases BMR

If you remmeber my BMR Is also much lower than the equation calculated

and I have been doing this a long time also.

I think the small term changes up and down in BMR related to small term

changes in food intake are to adjust for minor changes in food supply in

a natural environment. Maybe that is what is meant by 'set point'.

I agree that as long as the caloric intake is low, BMR stays low. But,

what if the person goes back to eating more on a regular basis. Does BMR

stay low.

While I have never done that longterm, I do know I can add weight much

faster than ever before, even with activity being constant.

Jeff,

I have looked more into the decrease in BMR associated with CR. The

changes seem to be permanent as long as the caloric level remains low.

Some CRONies, e.g., Liza May, who has been on CR for over 20 years have

substantially lower BMR than calculated with the Mifflin-St Jeor

equations.

I imagine that the opposite is also true. As long as you overeat, your

BMR will be higher.

The body adjusts BMR based on the availability of food. This fact

provides support for the concept of " set point " , but unfortunately not

enough to be able to quantify it. " Set point " would correspond to the

caloric intake where the BMR is neither increased nor decreased by a

corresponding deficit or surplus of food, i.e., Perfect Balance.
