There are some huge differences in how men and women process food, for sure. A big one is meat. Women absorb iron up to 10x better than men, and iron affects insulin production. Now, I can imagine that a man on the hunt is going to be eating mainly game. That's pretty much what modern hunters do. Read Lewis and Clark ... trek all day, then shoot something, roast it, and eat it around the campfire. Whereas the women and children in camp are roasting tubers, grinding grains or legumes, gathering greens and fruits, catching fish and finding eggs maybe. Also in some societies, men got the first choice on meat, and sometimes the women and children got very little ("meat is man food"). So the iron absorption issue makes sense that it would be different, and I think iron is a key to some of the health issues. And it varies according to genotype too, and age.
No group though, noshed on Snackwells or energy bars. Pretty much none of the "tribal" choices have a huge insulin rush attached to them, and it's really hard to overeat on most of those diets. If you look at "What I Eat", the portions on some of those diets are pretty huge. The foods aren't so calorie-dense and they are high in fiber.

I haven't had any problems on Fast-5. I lost 10 lbs. Then I gained it back when I started eating 3 x a day again.... :-(
On another list, someone speculated that in hunter-gatherer societies, that men fast more often; as in the time it takes to hunt, they are not eating. While women gathering plant food can snack on it while they are gathering.... hmmm.
Anyway, it always ends up that you just have to try something and see if it works.
Me, I have more energy intermittent fasting. I feel fine.

They are different, of course, and one can see from reports here that not only are men different from women, but wo...men are different from women -- two women do the same thing and have vastly different results. Why? Different genes, different epigenetics, different environments, different food choices, different activities, different bodies, different brains. That's why I encourage "the study of one" -- experimenting to find one's best options -- for your body in your environment. Glucose is easily tested at home, and I would balance that with periodic HbA1Cs, because decreased muscle uptake of glucose because they're burning fat instead may make glucose have higher transient swings than one sees on a usual diet while the average level may be higher or lower over time. Like most things, fasting obviously shows the phenomenon
> of hormesis -- a little is good, but the extreme is starvation, obviously bad. In the same way, a little water is good, but too much can be lethal. What the ideal interval is remains to be seen, but people have to be doing different things for a long time for researchers to be able to sort out what does what. I also keep in mind that lab animals are not normal animals (they're inbred in almost all studies) and they are not in normal environments -- rats and mice are kept in little cages, usually without room to roam, and fed food that is unlike the diet of their wild kin, but exactly the same with every feeding.
> So, while studies may make us think, I maintain that the best source of info is what's going on in our own bodies, in our own environment, with our own food choices. We have the technology to know that know, so I think we should collect this information (glucose, HbA1c, blood pressure, etc.) and use it to find our personal best approach. When a change makes one value get better and another worse, such as when glucose goes up and bp goes down -- it's a very tough call as to which is better in the long run, and the preferable route may be guided by personal and family history. Maybe when lots of people have done different things for decades, we'll be able to sift through it all and get better guidelines for what's best. The only thing that's clear now is that the current way of eating in the current environment with the current food choices results in an unhealthy outcome for the majority of people.
