From everything that I’ve read, you can do well with fat loss utilizing intermittent fasting like the method you described. Most of my fat is now concentrated at my center, mostly in my belly but also not limited to back, chest, thighs too. Extended fasting seems to be the best method to deal with that more stubborn fat. Once I’m at a better % (in my opinion like 15-18%) at the same weight, I’ll probably stick to IF. This is fun though, and I never have to worry about what to have for lunch at work, I eat books instead.
The other benefit to extended fasts is autophagy, where old cells will be recycled. I don’t want to give you an education if you already know about this stuff so if it’s foreign just ask.
As far as how much, I like to think it’s the weight training that’s causing the hunger like that. It’s definitely not sugar cravings that’s for sure.
But yeah, once the stubborn fat is dealt with, hoping for a few more months, then I’ll be more frequent with feeding probably, and instead of trying to abstain from eating for 5 days on end, I’ll eat when actually hungry and listen for those signals more closely.
