Lots of interventions that work in animal models do not work in humans. Physiology is different as is adherence. Humans control their own diets, so a really difficult diet will simply result in no humans sticking with it.

Humans aren't even monkeys. So it's not surprising that "works in monkeys" is a mediocre proxy for "works in humans".

Well then here is human trials:

In a pilot human trial, three cycles of a similar diet given to 19 subjects once a month for five days decreased risk factors and biomarkers for aging, diabetes, cardiovascular disease and cancer with no major adverse side effects, according to Longo.

BOOM.

Like many intermittent fasting proponents, you look at these studies that enforce days of significantly-reduced caloric intake and assume that a positive result there transfers to "skipping dinner or breakfast" just because both are referred to as "intermittent fasting". Even if 5 days of significant caloric restriction extends lifespan, that in no way indicates that 14-16 hour fasting does.

Also, I never said that intermittent fasting was ineffective in humans. I said that animal models do not always map well to humans. Scientists who use animal models understand their shortcomings. You should do some basic research before throwing up your arrogant "boom" as if you proved something.

Why don't you look at the actual article?

Which article, the one about eating after 8pm having no relation to obesity in children that has pretty much nothing to do with intermittent fasting? Yeah, I read that one.

Or the one you randomly quoted but didn't even bother to provide a link to? The one that did a pilot study in humans specifically because the researchers know that animal studies don't always map well to humans? The one that did a 5 day fast rather than just skipping breakfast? I read that one, too.

how about starting with basic physical anatomy and then move on the other differences. Also for starters bigger brains, faster metabolism,etc..

unless you consider the above don't have an impact on our food eating and fat storing mechanism.
