When you change two things at once--less fat, more whole grains etc (really
more than one thing) how do you know which one caused the change? You can
only get accurate results when you test one thing at a time. Remove the
fat, don't change anything else. Add fruits or veggies or whole grains,
don't change anything else. d

That study was attempting to keep unchanged either calorie consumption,
or level of food intake to have the study participants making the change
to maintain their level of satisfaction with their food intake.

I do consider that the decrease in the precursor to a common cancer
probably decreased more from increase of antioxidants/vitamins and fiber
than from decrease of fat. (The cancers that follow were not effectively
tracked by that study or the applicable subset of that study as of the
time of the major-news-headlines because that portion of that study was
only 8 years old then and it usually takes much longer than that for this
common cancer to develop ftrom cancer from "original cause").

Please keep in mind that changing the study conditions to ones that
result in major body weight change have effects of their own on cancer
rates - it is well established that fatter people get more colo-rectal and
breast cancer and less-overweight people get less colo-rectal and breast
cancer.

(Men with "man-boobs" beyond pectoral muscle mass to any extent even
minor or overweight at all - please beware that 7/10 of 1% of breast
cancers in USA, a very common cancer having notable correlation with
overweightness, strike men.)
