Re: CRON Weight Target Measures

My Tanita says 19, too, and I know it is incorrect. Peg

My BMI right now calculates out to 24.4, at 73 " tall and 185 pounds. I'm

very active in bicycling, hiking/backpacking, mountaineering, and

cross-country skiing. Last year I had a BF% test done that put me at 14%.

My doctor, who's aware of my CRON lifestyle, but repeatedly cautions me

about overdoing it, tells me that I shouldn't go any lower.

I believe it.

My BMI is 19. My Tanita Scale's body fat analysis reads either Error or 1%,

but I think it's pretty far off.

Hi All,

What CRON sifestyle or should it be whose? BMI = 24.4 is not CR, I

suggest.

Perhaps we have an Ob-Ob human here who can eat less and weight more. For me

to speculate on whether he is restricted or not I'd have to know what his

set point is, and I can't even figure out mine.

My BMI (22.8) is a lot closer to his than yours and I'm actively trying to

gain some muscle, if possible without gaining any more fat.

This is not a competition... the skinniest person doesn't win. IMO the

skinniest individuals aren't likely to live longest, or longer, or long. BTW

I hope you have managed to put on some weight.

This is all about moving our personal eating habits toward a more healthful

pattern. Until we get a better handle on the underlying mechanisms I'm very

reluctant to advocate extreme restriction.

Moderation, moderation, and then some more moderation.

JR: My words almost exactly! Besides we don't know Steve's original weight (it could have been very high). And even if we did, weight has nothing to do with CRON although it's sometimes difficult to remember this.

CRON is eating fewer calories than one would ad lib, and those calories should be the healthiest possible. If one loses weight (and most do) fine, but weight is a side effect and not the goal! The goal is better health and longer life.

At 1700-1850 calories per day, after 10 months on CRON my BMI is 26.6

and my body fat is 22%. My weight of 170lbs is unchanged since

September. I have been unable to get below 165lbs since I developed

thyroid problems many years ago - despite taking adequate amounts of

thyroid supplements.

I find your comment to be very generalised.
