There was a really good episode of "Explained" on Netflix that talked about diets. They took a study group, and gave half of them low-carb, and the other half a low-fat diet. Both groups lost weight equally. They didn't lose weight because of that particular diet, they lost weight because they made better decisions daily, stopped eating out, and stopped buying processed foods.

What did the study consider to be "low-carb"?

I don't recall specifically, it was a TV show I watched a few weeks back.

I find your question interesting, though. Why do you not care about what the low-fat diet was as well?

Also, since they lost weight on the low-carb diet, I can only assume that it's one that works!

A little more info on Dr Berg: he's a chiropractor doctor not a medically trained doctor. He has a lot of good information, but it's also wise to verify any of his info from other sources.

It's wise just to disregard anything and everything he says.

Unhelpful and mean-spirited. Not a comment worth posting on hacker news.

If you've never explored fasting for a couple days as an adult, it's definitely worth the experience.

Once the body gets into the fat-burning mode and all the pangs of hunger and mild headaches vanish, everything changes and it's like you can go climb a mountain with nothing but water.

Those familiar with atkins/ketogenic diets will have already learned this stuff about themselves. But it's interesting to note that the same operating mode is available without any food at all.

Even if you don't embrace fasting as some kind of healthy practice, being aware that; no, you're not actually starving when you're hungry because you haven't eaten carbs for a few hours, seems like a useful fact to internalize. As long as there's fat on your person, you're not starving, just stop eating long enough to give your body a chance to switch fuel sources.

It's actually a quite different experience to run off fat, the headspace is changed, there's a mental clarity and physical lightness and agility (you're empty). I find it quite pleasant, especially for physical activity.

Nobody fasts for 24 hours. This study lacks to mention if say same affects were observed based on shorter amount of fasting time.

Before anyone breathlessly gushes about their life-changing fasting regime, remember that this study was done on mice.

There have been studies on people as well, with encouraging results: http://stm.sciencemag.org/content/9/377/eaai8700

as well as

Still, more work needs to be done.

The thing with fasting/low-carb is that once you are adapted it takes quite a bit more to "feel hungry". In fact the feeling is qualitatively different. I eventually tried the low-carb (actual low-carb of It was like the scales fell from my eyes when I realized that much of what I thought was "hunger" my whole life was actually "addictive cravings" for carbohydrates. And I was really not a fan of grains and sugary st…

How long did it take you to become adapted?

It took a while for me to start burning fat efficiently when I started keto. YMMV. Day 1 was ok, 2 was difficult, 3 was the worst - had a persistent headache and my mind was at maybe 50% of what it is normally. After that I was fine, except for two issues -

1. I didn't feel hungry anymore, so I didn't want to eat. I had to force myself to eat protein so I wouldn't lose muscle.

2. I couldn't do strenuous exercise for at least a week afterwards. I could walk for several km at a time but running was difficult. Running up stairs even more so. But once I was fully adjusted to the diet 7-10 days in, I could do all of those things.

I'll return to this diet later this year. Really looking forward to it.

This might interest some of you - it is a documentary on the same topic - where a doctor goes ahead and explores intermittent fasting for longevity / reducing aging issues. He ends up trying it and becoming a convert. https://vimeo.com/170735109 This doctor (Dr Berg) also has a channel on the same - and provides some interesting easy to understand scientific explanations on different intermittent fasting related item…

A little more info on Dr Berg: he's a chiropractor doctor not a medically trained doctor. He has a lot of good information, but it's also wise to verify any of his info from other sources.

Needs appropriate quotes

A lot of people fast for 24 hours. I do it once a month. Where did you come up with the ridiculous assertion that nobody fasts for 24 hours?
