No need to even skip breakfast. Have breakfast at 10 AM and dinner at 6PM and you are IF'ing, or, as we commomers like to call it, eating .

Even the researchers are admitting that their research is useless. From the article:

"No changes were observed in the level of estradiol, estrone and progesterone in post-menoapusal women after the eight-week regimen.

Speaking to the utility of the data, Varady said, “I think this is a great first step. We’ve observed thousands of pre- and post-menopausal women through different alternate-day fasting and time-restricted eating strategies.”

“All it’s doing is making people eat less. By shortening that eating window, you’re just naturally cutting calories. Much of the negative information on IF reported has come from studies on mice or rats. We need more studies to look at the effects of intermittent fasting on humans,” she concluded."

There are a lot more effective ways to consume less calories than starving oneself. One could consume an abundance of whole plant-foods (other than a few high fat ones like nuts, seeds, avocados) that would be calorically dilute yet satiating. Of course, one cannot do that on the idiotic keto diet, which is why its adherents resort to intermittant starvation.
