The following sources provide some compelling arguments for switching to intermittent fasting for many major systemic health benefits. These videos by the channel "What I've Learned" are great: - Fasting vs. Eating Less: What's the Difference? [1] - Longevity & Why I now eat One Meal a Day [2] The channel [3] also has many other videos on the topic of nutrition, with similar emphasis. Also see the excellent and readable book "The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting" by Dr Jason Fung and Jimmy Moore [4].

I saw this video called "Fasting vs. Eating Less: What's the Difference? (Science of Fasting)" just yesterday, and it's good to hear many of the points it raised validated by your experience: [this video] > hunger comes in waves, you'll get to a point where you feel super hungry, it'll usually pass after some time Matches what the video above talks about "Ghrelin" from 5:03 onwards.

Yeah my man, I seriously don't know what to tell other than fasting works. Your metabolism isn't a something that breaks and is not fixable, and "getting sick of fainting" isn't a fucking excuse.

I wouldn't say there's any one good resource. Most people preach intermittent fasting, which I've found is okay for maintenance and health but it's not nearly as beneficial nor will it lose you as much weight as fasting for days on end. But here's some material I went over to educate myself and convinced me that it's perfectly safe: Fasting vs. Eating Less: What's the Difference?

What really opened me up to all of the complex biochem when processing different foods was the “what I’ve learned” youtube channel [1]. What you describe was actually tested by the US government with the starvation experiment around ww2 and is consistent with your symptoms. Apparently when people are kept on a carb diet, but not given enough carbs, their live would suck quite a bit, they would loose muscle (but gain fat), not be able to think straight, etc. Its all fascinating stuff. I would suggest trying a full water fast for at least 2 days to see how it goes. For me its much less stressful, and after I get rid of all the carbs (24-48 hours, depending on what I was eating before) I would
