So, let’s get to the actual dietary numbers for bulking. Here’s where you start: • 1 gram of protein per pound of body weight per day, • 2 grams of carbs per pound of body weight per day, and • 0.4 grams of fat per pound of body weight per day. That’s where you start. For a 150-pound guy, it would look like this: • 150 grams of protein per day, • 300 grams of carbs per day, and • 60 grams of fat per day.
