I fast Monday Wednesday and Friday. Only coffee and water on those days. Maybe a zero calorie LMNT packet if you are craving sweet or salt.

On Tuesday Thursday and weekend - eat whatever you want. You’ll do better if you keep it to Whole Foods and veggies, but we aren’t strict. My wife and I have also done a couple 2 day fasts during this time.

It’s honestly incredible. Somewhere around the 24 hr mark you switch over to burning fat because insulin is completely down and glycogen stores are expended. Most people never deplete glycogen, so they never burn fat, even when eating at a caloric deficit.
