Building lean muscle mass isn’t just about lifting heavy weights; it’s about fueling your body correctly. To grow, you need a caloric surplus—consuming more energy than your body burns. The secret to optimal gains without excessive fat accumulation is to find your Total Daily Energy Expenditure (TDEE) first. Once you know your maintenance calories, adding a modest surplus of 250–500 calories per day is the sweet spot for steady, sustainable muscle growth.
Calculating your target intake is straightforward. Start by using an online TDEE calculator to estimate your baseline, then add your chosen surplus. Remember to track your progress weekly; if you aren’t gaining weight, nudge your intake up slightly. If you’re gaining more than 0.5–1 lb per week, you might be overshooting your target, which leads to unnecessary fat gain. Keep your nutrition high-quality, stay consistent with your training, and watch your hypertrophy results transform.
