I remember an article about a fellow who was doing caloric restriction in Portland, OR. He was described as going from entirely average build to at the edge of under weight.
I personally maintain a weight at the edge of under weight generally consuming a high level of calories (and this is in my 50s). I doubt I could survive calorie restriction.
Anyway, maybe it's sour grape but I suspect the whole calorie restriction thing is boondoggle based on ignoring the variety of factors influencing calorie consumption and longevity outside very controlled circumstances. If normal lab mice (or monkeys or some humans) are fat and inactive, calorie restriction might be good for them while it might be very bad for active animals.
