What it does not prove
- Non-randomized assignment introduces selection bias: participants self-selected their group and diet, so differences between groups may reflect initial characteristics rather than training effects
- No sample size, effect sizes, or specific outcomes reported in the abstract, preventing assessment of whether changes were clinically or statistically meaningful
- Observational design cannot establish causation; diet type was not experimentally manipulated, so claims about diet efficacy rely on post-hoc comparisons of self-selected groups

Abstract or registry material supplied for assessment; source version 1. This is not a claim of full-text review.
The study consisted of a non-randomized controlled clinical trial with measurements at baseline and at the end of a 16 week intervention.
Participants will be assigned to the intervention or control group according to their own choice and convenience.
A 4 arm split was performed where the Veg-Int group was composed of people on a vegan diet who participated in the intervention, the Veg-Con group was composed of people on a vegan diet who were part of the control group, the Omn-Int group was composed of people on an omnivorous diet who participated in the intervention, and the Omn-Con group was composed of people on an omnivorous diet who were part of the control group.
The Veg-Int and Omn-Int intervention groups, participated in a physical exercise program in remote modality through a digital mHealth platform. During the 16 weeks of intervention, a total of 50 training sessions were carried out, distributed in three sessions per week, with a duration per session ranging from 40 to 50 minutes.
