Question: how many calories do you need to eat when intermittent fasting?
Answer: So if you can't hit the 1,500- or 2,000-calorie mark in 4 hours every day, it's OK. If falling below 1,200 calories a day becomes a regular habit, though, reconsider your diet plan. If you're not sure how many calories you're consuming, track them in a free app like MyFitnessPal.
