I’ve been doing it for 3 months and have lost 34 pounds, so a little over 10 pounds a month. Calories less than 1600, minimum of 16 hours fasting but no more than 20, and low carb foods only. I walk 30 minutes a day on the treadmill.
I do 48 hour fasts and get 10 miles a day in between walking/ jogging. Counting calories has always stressed me out so I instead pay attention to just eating a protein/ veg focused/ non-processed meal and eating until satisfied. Taking vitamins along with meals as well.
I have a lot to lose though too. As I get closer to my goal weight I plan on scaling down my fasts to eventual 18 hour fasts or 20 hour fasts.
