Stop obsessing over macro ratios (especially carbs vs fat)

For most lifters, carbohydrate intake (and carb/fat percentage differences) is largely irrelevant for muscle/strength if:

  • Protein intake is sufficient
  • You’re not eating in a major energy deficit
  • Fat intake is at least above a minimum healthy level

The “40/45% carbs vs 20/25% fat” debate is best viewed as fine-tuning, not a major driver of results for most people.

Prioritize the “big 3” for gains

Focus on:

  • Protein intake
  • Total energy intake / energy balance
  • Training volume (sets per week per muscle group)

If you want muscle growth: lean bulk, avoid large deficits

General guidance:

  • Outside of a deficit:
    • Extra calories tend to add more fat than muscle/strength.
  • In an energy deficit:
    • Larger deficits can reduce muscle protein synthesis and impair growth.
  • In an energy surplus:
    • Benefits plateau; surplus beyond a small amount mostly adds fat.

Use a controlled, adaptive surplus (lean bulk approach)

Approach:

  • Start with the largest surplus you can tolerate without “spilling over” into fat gain
  • Adapt based on measurements (e.g., waist circumference and skinfold calipers)

Rule of thumb:

If waist/skinfolds are trending up week-to-week, you’re likely overshooting—reduce the surplus.

Carbs may matter mainly in extreme or endurance-like contexts

Carbs may matter more when training includes:

  • Very high volume per session (roughly >10 sets per muscle group per workout)
  • Concurrent sports (e.g., tennis, soccer, kickboxing), where glycogen depletion is higher due to constant activity

For conventional lifting with typical rest periods, carbs generally aren’t needed for performance or hypertrophy beyond placebo-like effects.

Productivity / self-management style techniques (from the app-based method)

Track outcomes and let data drive adjustments

Monitor:

  • Body weight
  • Body fat measures (e.g., skinfolds)
  • Macros
  • Other relevant metrics

Then:

  • Automatically adjust energy intake to stay in the “sweet spot” of gaining muscle while limiting excessive fat gain.

Evidence claims highlighted (study/review conclusions)

Within-subject study (16 weeks, trained men)

  • Intervention: adding ~50g extra carbs (vs ~215g baseline typical intake)
  • Result: no meaningful differences in:
    • Body composition (DEXA)
    • Muscle size (ultrasound)
    • Strength (1RM squat)
    • Quad performance (peak torque)
    • Fatigue index

Systematic reviews / meta-analysis mentioned

  • Short-term performance/strength effects: mostly no significant carb effect
  • Long-term strength/muscle outcomes: most studies show no significant advantage of higher carbs
  • Findings that appear to favor higher carbs are often explained by higher total energy intake, not carbs specifically
