Those who are genetically prone to anorexia nervosa can also develop that if they practice intermittent fasting.

“Genetically prone” as in Mendelian heritability? SNPs? Links to studies?

Men do indeed face judgement over what they eat — if they’re overweight. More so if they’re obese.

The point of time restricted eating (the most common form of intermittent fasting) is not to lose weight but to promote 'fuel flexibility', making the body better at switching from glucose to ketones and back, which promotes insulin sensitivity, as does exercise.

There have been some studies (e.g. by Dr. Sachen Panda) showing that early TRE is more effective than late. His take on it being that the eating window needs to line up with our circadian cycle. This makes sense to me as insulin sensitivity is highest shortly after we wake — and there is some association between ‘skipping breakfast’ and insulin resistance.

Are some people treating it as a fad diet? It wouldn't surprise me. But at least some of us looked at the science and decided that it was a do-able step towards staying healthy. My dad had T2DM, so if something has evidence that it'll help prevent that, I'm in.
