Here's my chance to be more precise. First, I wasn't saying that all
women do better on a heavy diet; rather, certain individuals of both
sexes thrive best on such a diet, and the majority of these people are
female. Rudolf Wiley (author of "BioBalance") estimated that about 15%
of men and 50% of women should eat a relatively heavy diet. Classifying
women is somewhat complicated by the fact that half of them cycle
between metabolic subsets during menses; this is probably a recent
phenomenon.
Also, the "light" and "heavy" labels I used are misleading. Generally
speaking, "heavy" refers to a diet relatively high in protein, fat, and
purines, and relatively low in carbs; the opposite description applies
to "light" diets. Using Dr. George Watson's terms, people adapted to a
heavy diet are "fast oxidizers" and people adapted to the opposite
extreme are "slow oxidizers." (Wiley uses the terms "acidic type" and
"alkaline type," and a friend of mine prefers "Hunter-Gatherer" and
"Agriculturalist". Unfortunately, all of these labels are misleading in
some way.)
However, our ancestors ate foods, not isolated nutrients, and the effect
of a given food on one's metabolism can be counterintuitive. Fast
oxidizers have a low tolerance for carbohydrates, yet certain high-carb
foods, such as parsnips and carrots, actually assist their metabolism
(eaten in moderation, of course). Broccoli is low-carb, yet it has the
opposite effect, as do nightshades, onions, garlic, and citrus. As a
general rule of thumb, foods native to Northern Europe agree with fast
oxidizers. Mind you, all of the research on metabolic subsets has
focused primarily on subjects of European descent; perhaps these
guidelines will need to be changed for people of non-European
ethnicities.

Thank you for the abstract. I enjoy hearing about any research that
suggests weight loss (or gain) is more complicated than simply counting
calories.
