The Truth About Building Muscle (No BS)

You cannot build muscle without:

  • A calorie surplus โ€” you need to eat more than you burn. A modest 250โ€“500 cal surplus minimises fat gain.
  • Enough protein โ€” 1.6โ€“2.2g per kg bodyweight daily. For an 80 kg person, that's 128โ€“176g protein per day.
  • Progressive overload in the gym โ€” you must lift heavier or do more reps over time. No amount of food builds muscle without this stimulus.

That's it. Supplements help at the margins. The three points above are 95% of the result.

How Many Calories to Eat to Gain Muscle

Protein โ€” The Most Important Macro for Muscle

Aim for your protein target FIRST. Fill remaining calories with carbs and fats. Best NZ protein sources:

Timing Your Nutrition Around Training

Timing matters less than total daily intake โ€” but these habits help optimise muscle growth:
