Start with the daily total
A meta-analysis of 49 studies with 1,863 participants found small average improvements when protein supplementation accompanied resistance training. Its segmented analysis estimated 1.62 g/kg/day, with a 95% confidence interval from 1.03 to 2.20. That range describes model uncertainty; it does not show that every person stops responding above 1.62.
Protein is only one part of the system. A perfect target on paper cannot compensate for inconsistent training, insufficient energy or a routine that is not progressing.
Calculate a reference, not an obligation
| Body weight | Daily reference | Across 3 meals | Across 4 meals | Across 5 meals |
|---|---|---|---|---|
| 60 kg | 96 g | 32 g | 24 g | 19 g |
| 70 kg | 112 g | 37 g | 28 g | 22 g |
| 80 kg | 128 g | 43 g | 32 g | 26 g |
| 90 kg | 144 g | 48 g | 36 g | 29 g |
Per-meal figures are rounded for organization, not precision. You can eat three, four or five times according to appetite, schedule and preference. If the total forces every meal, review the reference and the broader diet with a professional instead of chasing decimals.
A flexible day
A 70 kg person uses 112 g as a reference: 25 g at breakfast, 32 g at lunch, 20 g as a snack and 35 g at dinner. They do not need identical meals or exactly 28 g four times.
Distribute it without chasing a magic window
A review limited to studies directly comparing protein immediately before versus after training found no important lean-mass difference, although only five eligible studies were available and certainty for some outcomes was limited. The prudent reading is that sacrificing daily intake or adherence to gain a few minutes on the clock is not useful.
Even distribution can be convenient and prevents moving the entire target to the end of the day, but a systematic review found insufficient evidence that one distribution pattern universally improves muscle mass, strength or protein turnover.
- Choose the total
Start from a reference compatible with your health, body size and diet.
- Count real meals
Divide by the meals you can already sustain, not an idealized schedule.
- Build two or three anchors
Add clear protein sources to meals that commonly fall short.
- Adjust for adherence
When the plan is repeatedly missed, simplify before increasing the number.
Food first; supplement optional
- Choose foods that fit your preferences, tolerance and budget.
- Combine sources across the day when your diet is predominantly plant based.
- Use a shake only when it solves a practical constraint; it is not required for hypertrophy.
- Review total calories because added protein also adds energy.
- Do not replace a varied diet with products promising rapid results.
Where BUSTAFIT fits
BUSTAFIT lets you keep nutrition, calories and macros alongside training on iPhone. You can check whether the protein target coincided with genuinely comparable weeks of load, repetitions, RIR and volume. The app does not calculate clinical requirements, prescribe grams per kilogram or decide what foods you should eat.
Short weekly review
Editorial target: 112 g. Logged average: about 108 g; four workouts completed; performance moving up. Output: hold. Chasing four extra grams would not improve an already well-supported decision.
