1. Make sure you consume adequate calories every day
The bottom line is you can’t add weight if you aren’t taking in more calories than you’re burning. If you’re trying to pack on muscle, you have to consume enough surplus calories to support that growth. If you’re heftier to begin with, this task is a little trickier. You need to get enough calories to add muscle mass, but you also want to avoid an excessive increase in bodyfat. While you’re adding muscle mass, you should regard maintaining or just slightly increasing your bodyweight as progress.
2. Split your total calories fairly evenly over 5–6 meals per day
This recommendation is a bodybuilding standard. The more frequently you feed your body, the better the contribution you’re making to build muscle mass while at the same time avoiding the addition of bodyfat. If you consume 3,000–4,000 calories over six meals versus just three meals, your metabolism will stay elevated and you’ll gain more muscle and much less bodyfat. Those who consume the same number of total calories, but in fewer, larger meals, however, send their bodies the signal to store bodyfat.
