Question: how many calories per day on intermittent fasting?
Answer: Just make sure you aren't going below 1,200 calories a day. The only exception is if you are doing the 5:2 method: five days a week you eat normally (for example, 2,000 calories a day) and two days a week on your fasting days, you eat only 20-25 percent of your average calories (so 400 to 500 calories).
