I am new to intermittent fasting, doing 16:8. Are you supposed to follow any type of diet when doing this like low calorie, high protein, etc… or can you eat what you normally eat within reason?
You can eat whatever you’d like within reason. Assuming your goal is weight loss, you should eat fewer calories than your TDEE. Some are good at estimating, and just eliminating a meal with IF is sufficient, others need to count calories and plan meals to avoid overeating during their eating window.
