Eat Multiple Meals

Since you're now eating 4000 calories per day, your next best bet would be to eat 6 meals a day. Although this may seem like a lot, it really isn't. Do the math. If you divide 4000 calories into 6 smaller meals a day, then each meal will consist of approximately 660 calories.

Trust me when I say that 660 calories isn't a lot. Although it takes a lot of discipline, eating smaller and more frequent meals will pay off in the end. Another reason to eat smaller meals is for the release of insulin. When you consume food, your blood glucose levels will rise.

To counteract this, your body will release insulin to lower blood glucose levels to help keep the body in a state of homeostasis. As you now know, insulin is the body's most anabolic hormone. The more, the better. So basically, you want as much insulin secretion by the pancreas as possible. After all, you want to be big, right?
