Building quality muscle requires quality calories, and it requires a lot of them (if you’re striving to put on serious mass). Eating a high-calorie diet isn’t actually hard…Unless you’re worried about the quality of food you’re eating. Eating a lot of calories while keeping it healthy isn’t so easy, and doing it without breaking the bank at the grocery store is almost impossible.
On top of the costs, there’s also time and convenience to consider. Not everyone can carry around a cooler full of homemade meals, let alone the time it takes to warm everything up and force feed yourself on a time crunch.
