Re: The definitive study on dietary fat and weight

Susan, what precisely is your point?

That too much sugar is bad for you? The low glycemic foods are, on
average, to be preferred over high glycemic foods? You are preaching
to the choir.

Per capita sugar intake increased by about 10 Kg per year between the
late 70s and mid 90s, during a period of time when per capital calorie
intake increased slightly and per capita exercise (objectively document
by nationalized physical fitness testing in school children and
military recruits) plummeted.

So people started putting sugar in their whole milk and stopped
exercising.

And they got fat and diabetic.

None of the above in anyway negates the monumental importance of the
JAMA study of 50,000 women.

Some of the women ate "good" carbs. Some ate "bad" carbs. Some ate
"good" fats. Some ate "bad" fats. Some exercised. Some didn't. So
there is obviously a lot of background noise.

But, clear as a bell, there was an inverse linear relationship between
changes dietary fat intake and changes in body weight. You may never
see such a clear and striking relationship in any large population
study in another 10 years. The dose response relationship between
dietary fat intake (on a population basis) and weight change is about
as clear as the dose response relationship between incidence of lung
cancer and cigarettes per day smoked.
