I mostly do 16/8 intermittent fasting. Honestly, it's hard. You always hear people talking about the correlation between anger and hunger. I'm one of those people I think, but more than just anger... There are lots of mental processes that seem tied to food.
I'm sticking with it for now, but I've started to think that fasting is better for people whose mind, in general, is less sensitive to eating.
On the other hand, it might just be that people who are less happy exacerbate their faults by fasting.
