72 hr fast questions.

I want to maximise autophagy so I am thinking of doing 72 hr fasts every week starting friday morning up till monday morning.

This is what I’ve researched so far:

18-20 hrs:

• Autophagy begins

• Ketones released

36 hrs (1 ½ days)

• Autophagy increased by 300%

48 hrs (2 days)

• Cellular regeneration starts

• Inflammation goes down

72 hrs (3 days)

• Autophagy peaks

1. From what I’ve heard, some people do like 3+ day fasts going up to 5 days or more. Are they only doing this for faster fat loss or is there some kind of benefits I don’t know yet?

2. After a fast some people eat and then get right back into a fast for the following days to come. Is this also just for fat loss.

3. When you break your fast I understand you have to eat light at first but do you have to eat your normal calories for that 1 day or should you eat a lot more because you fasted?

That is all, thanks.
