This article investigates the popular belief that consuming excess calories is essential for maximizing muscle growth during resistance training.
While adequate calorie intake is important, recent research suggests that maintaining a balanced diet with sufficient protein intake (1.2-1.5 g/kg/bw), rather than being at a surplus of energy, is crucial for muscle development.
If you want to look leaner and toned instead of bulky and bloated, staying at an energy balance, or even a small energy deficit, while keeping up your protein intake and resistance exercise is the best strategy for you.
