Hi P-hackers. So, I've tried intermittent fasting in various forms 16/8 with 3 meals and 20/4 with 2 meals, and I simply cannot do for any longer than 10 days consecutively. I am used to eating literally within an hour after rising, and then having smaller meals every 3 hours after that. I have gone through probably a total of 10 bouts like this, where I IF for 10 days, and then start just getting anxious all the time, feel like I'm starving (even if I'm eating the same amount of calories as before), and I start spending my time thinking about when I can finally eat again. so I eventually resort go back to my regular eating intervals.
Does this mean my brain is somehow messed up? People say not to try IF-ing until you're healthy or something like that. I am otherwise very healthy- validated by (conventional) doctors, as well as how I feel and perform (both physically and academically). Why can't I intermittent fast for very long? AM I doing something wrong? Is my brain chemistry abnormal?
Thanks for your responses.
