Yes, came to say fasting. Start with intermittent. Work up to OMAD (one meal a day). Then push it further out to 48 hr. plus depending on your weight, with just water, vitamins, electrolytes.
Autophagy is an amazing benefit of it to look into as well. Kicks in hard around 48 hrs, depending on how much sugar and carbs you have to burn off. Which is also why a ketogenic diet is good when you aren’t fasting.
Green tea, coffee, tumeric are good at stimulating autophagy too, if you want to dirty fast
Cravings wear off fast. Especially if you are not dry fasting. It’s actually easiest after the second day or so if you are getting you electrolytes
