Why distribute protein evenly instead of one big meal?

Muscle protein synthesis is stimulated per meal and plateaus once a dose passes the leucine threshold. Spreading protein into three to five moderate doses keeps synthesis elevated through the day more effectively than one or two large servings.

What is the leucine threshold?

Roughly 0.7 to 3 g of leucine per meal maximally triggers muscle protein synthesis, which corresponds to about 20 to 40 g of high-quality protein for most adults. This tool uses a 25 g per-meal benchmark as a practical minimum effective dose.

Does protein timing around training matter?

The post-training anabolic window is wider than once believed, but a protein dose within a couple of hours of training is still sensible. The tool flags one meal as the post-training serving so you can plan it around your session.

Is more meals always better?

No. Beyond five or six doses each meal may fall below the effective threshold, and very frequent eating offers little extra benefit. Three to five protein-rich meals per day is the practical sweet spot for most trainees.

Does this replace total daily protein?

No. Total daily intake remains the primary driver of muscle gain. Timing and distribution are secondary optimisations that help you use that total more effectively once you are already hitting your daily target.

Hitting your daily protein target is the main driver of muscle gain, but how you spread that protein across the day affects how much muscle protein synthesis you actually trigger. This calculator splits your daily target into even per-meal doses and checks each one against the leucine threshold.

How it works

Protein is divided evenly across your meal count, and each dose is checked against a practical minimum effective serving:

per meal     = daily target / meal count
threshold    = 25 g  (approximate leucine-threshold dose)
status       = per meal >= threshold ? optimal : below threshold

Muscle protein synthesis responds to each meal independently and saturates once a dose passes the leucine threshold, so several moderate doses outperform one or two large ones. One meal is highlighted as the post-training serving.

Example and tips

An 80 kg athlete targeting 160 g of protein across four meals gets 40 g per meal — comfortably above the 25 g threshold, so every meal maximally stimulates synthesis. If the same person split 160 g across seven meals, each 23 g dose would dip below the threshold. Keep meals in the 25 to 40 g range and place one around your training session.
