No alcohol
- Muscle protein synthesis
- Heart rate variability
- Evidence
- After a strength and interval session, alcohol cut muscle protein synthesis by 24% even when taken with protein. In 4,098 people it raised sleeping heart rate and lowered HRV, from low doses up. The intake that minimised overall health loss was zero.
- What I do
- None, ever.
- Caveat
- The 'no safe level' figure is population modelling, and the protein-synthesis study used a binge-level dose. At low intakes the absolute risk is small.
