The Claim

In healthy young males, ingestion of 1.5 g of alcohol per kilogram of body mass following a single bout of concurrent resistance and high-intensity exercise reduces maximal rates of myofibrillar protein synthesis by 24% when co-ingested with 25 g of whey protein and by 37% when co-ingested with carbohydrate.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If you drink a lot of alcohol after a tough workout — like 12 drinks — your muscles won’t repair and grow as well, especially if you eat carbs afterward; even if you eat protein, your muscle recovery still takes a hit.

See the scientific wording

Ingestion of 1.5 g of alcohol per kilogram of body mass (equivalent to 12±2 standard drinks) reduces maximal rates of myofibrillar protein synthesis by 24% when consumed with 25 g of whey protein, and by 37% when consumed with carbohydrate, following a single bout of concurrent resistance and high-intensity exercise in healthy young males.

  1. Study: Alcohol Ingestion Impairs Maximal Post-Exercise Rates of Myofibrillar Protein Synthesis following a Single Bout of Concurrent Training

    Scientists gave guys alcohol after a tough workout, along with either protein or carbs, and found that alcohol cut down muscle repair by 24% with protein and 37% with carbs — exactly what the claim says.
