/message/3990 " Subject: Re:

[ ] Re: Does CR Make You More Hungry? " . I thought the idea

that lighter ad libbers need less restriction needs serious consideration.

By what definition is 1800 calories ad lib 30% CR? "

Hi Al: glad you questioned this. If you don't agree, we may need some

healthy debate. My figure of 1800 cal was an estimate; the writer said she

was now eating 1200 cal. 1200 subtracted from an estimate of 1800 ad lib=

600 cal less on CR. That would be 1/3 less cal. or about a 30% restriction.

Of course many of us have no idea what we were eating ad lib since we never

tracked our cal before CR

Here are a couple of references from BT120YD.

1) slender people should lose less: pg.228 reduce your caloric

intake......until you are 10 to 25% below whatever your set point is for

body weight (10% if your set point and BMI place you as already slender, 25%

if obese)

2) discussion of % restriction: pg 49....At 10% caloric restriction ...

diet extended max lifespan (of mice) to 43 months, and at 50% restriction

(corresponding to something close to a 1200 to 1500 cal CRON diet in a human

male of avg size) to more than 54 months.......

3) another interesting reference that I thought I'd throw in on pg 137:

Clearly it's calories that count. .......Keep the calories down and the diet

nutrient dense and you will.....slip into the CRON adaptive response
