Reply to comment by MTL_t3k in A study has looked at how intermittent fasting can affect hormone levels in pre- and post-menopausal women. Previous work in this area had only been conducted in animal models. by molrose96

Bummer. I've been keto since 1/1/14 and started IF and long term fasting about 1.5 years late. I wonder, when does this stop being a "fad"?

Even when I started keto, I ate 5+ meals/snacks a day, as that's what we're taught to do. When I started fasting, I initially tried butter in my coffee, then skipped lunch. Then I tried skipping breakfast. That was 5+ years ago, and I haven't eaten breakfast unless we're on vacation since then.

I typically eat two meals a day. When I fast lately, I fast about 32 hours, exercise about 1-2 hours, then eat a few hours later. Eating 2-3+ hours after exercise is my normal now.

No one cares what you were 'taught' by some idiot on youtube.

Effect of a plant-based, low-fat diet versus an animal-based, ketogenic diet on ad libitum energy intake

This was a short-term dietary ward experiment. Even though the keto diet groups lost ~0.7 lb more weight (Fig 2g), they lost ~1.5 lb more lean mass (Fig 2h) and ended up with ~1 lb more fat mass relative to the low-fat diet groups (Fig 2i). The keto diet groups did worse across the board in terms of health bio-markers. Basically keto resulted in significantly higher cholesterol, reduced insulin sensitivity, higher uric acid, impaired thyroid function and being skinny-fat. And all of that in less than a month. No wonder the idiots who advocate for it also advocate starving to try to compensate.

Ketogenic Diets and Chronic Disease: Weighing the Benefits Against the Riskshttps://www.frontiersin.org/articles/10.3389/fnut.2021.702802/

"Given often-temporary improvements, unfavorable effects on dietary intake, and inadequate data demonstrating long-term safety, for most individuals, the risks of ketogenic diets may outweigh the benefits."

Regarding keto, there is literally no legitimate research showing long-term health benefits from following this idiotic eating pattern, and what little research there is suggests it can be harmful long-term. That is why no professional nutrition or dietetics association recommends it, and most actially caution against it.

Regarding intermittant fasting, as noted in the previous comment, the most common form is eating within an eight hour window, or what is known in most parts of the world as regular eating. Presumably, calling it by some other name adds some element of novelty to the research.
