On the other side of the coin, you might be looking to bulk, or determine your calorie intake to gain muscle. In this case, you’ll need to figure out calorie intake to gain weight, which means that you’ll be adding calories to your daily intake.
Similarly to figuring out your calorie intake to lose weight, you’ll need to set a goal for yourself based on your targeted rate of weight gain. Our recommendation for this: try adding about 200-300 calories per day. Again, you’ll want to make sure that you’re increasing your caloric intake for slow and sustainable weight gain, rather than adding on a ton at once.
