Protein Matters—But Training Matters Too
Simply eating more protein isn’t enough to build significant muscle.
Resistance training is a key part of the process. Studies involving healthy adults consistently show that increasing protein intake produces the greatest benefits for lean mass when combined with resistance exercise.
In other words, think of nutrition and training as two parts of the same strategy.
Exercise tells your body to adapt. Food provides the materials and energy needed for that adaptation.
Do You Need a Huge Calorie Surplus?
Not necessarily.
The original article suggests that a calorie surplus is required for muscle gain, but the evidence is more nuanced. A large calorie surplus isn’t automatically necessary, and gaining excessive body fat isn’t the goal.
A moderate increase in calories, combined with adequate protein and progressive resistance training, is generally a more practical approach for people specifically trying to gain muscle.
How Much Protein Do You Need?
There isn’t one perfect number for everyone.
Protein requirements depend on factors such as body weight, age, training status, total calorie intake, and goals.
Research in adults performing resistance training has found benefits from higher protein intake, with one large meta-analysis finding that gains in fat-free mass generally did not continue increasing once total protein intake reached around 1.6 g per kilogram of body weight per day.
