Benefits and drawbacks to doing a 48 hour fast? Anyone have any experience going 48 hours?

I mean, obvious drawback is being hungry and blood sugar/fatigue issues from going two days without food.

I've done fasts several times and FOR ME 48 hours would be way too short since that's about the time I get past the cravings.

This. 48 hours is still more in the calorie restriction / give your system a slight rest protocols. That supposedly is just when autophagy would start kicking in for any substantive effect.

Good way to get into ketosis though if you plan to go low carb after the fast (if you're into that sorta thing).
