Re: One meal per day not good for you

[Guest guest]

I wonder how many calories the one-mealers were forced to eat, and

what foods? I could imagine that if I had to eat a huge fatty meal

daily my blood labs would be awful.

Hi folks:

" ....... ARS physiologists Baer and Rumpler and NIA

neuroscientist Mark Mattson designed the study. "

Mark Mattson is certainly not going to do anything that might cause

invalid study results by making such a gross error as this. But I

believe someone who was posting here at the time it was being

planned had said they were considering participating in this study,

so perhaps, if they are still around, they could comment.

My view is that if someone finds it necessary to go to a one meal a

day routine as the only way to get caloric intake down to where they

want it to be, that is probably fine in the short term. But once a

targeted CR BMI level is established it would be preferable to go to

three meals a day.

OTOH, in many of the mouse and rat CR experiments the animals were

fed three meals a WEEK - Monday, Wednesday and Friday at 9 am.

Since these animals are nocturnal that is the equivalent of an

evening meal ~every other day in humans. The CR animals lived ~40%

longer than the normally fed animals. So it seems clear that the

reduction in calories is much more important than the meal spacing.

And it cannot be argued that meal spacing was a major contributor to

the longevity of the CR mice in these experiments, when in the

monkey experiments the 30% restricted animals are living 30% longer,

while eating three meals a day.

Some time ago, Lee Shurie, who posted on this list, went on a one-meal

diet to control his diabetes. Here is the web page describing how he

ended up with this diet:
