From the intro to the study: “In the OMNIVEG study, 14 healthy, physically active men followed a traditional MedDiet for 3 weeks and a vegan MedDiet for 4 weeks, with a 1-week washout.”
Small sample size. Highly selective criteria for choosing the subjects. Very short test duration. The impact assessments are opaque, arbitrary and massively over-extrapolated. None measure actual impacts, only projected impacts. This study is a methodological mess: all noise and no signal.
Do it again in a long-term longitudinal study with a large, diverse sample population, and measure real impacts, not proxies, then we’ll actually know something.
