Dietary intervention
Basal metabolic rate (BMR) was estimated using the Henry equations based on age, gender, and body mass [Baseline participants’ characteristicsValues represent mean ± SD. No differences between groups (all The nutritional content of the participants’ habitual diets and of the intervention diets during Phase 1 of the studyValues represent mean ± SD. Participants received a 3-d controlled, eucaloric, and high-protein diet, alongside daily unilateral resistance exercise, with deuterated water used to measure rested and post-exercise daily myofibrillar protein synthesis rates. In OMNI1, participants consumed an omnivorous diet with the majority of dietary protein coming from animal-derived sources. In VEG1, participants consumed a diet derived from non-animal sources with a large proportion of their protein coming from mycoprotein-containing products and mycoprotein. Both groups received 1.8 g·kg bmSubjects consumed a diet containing 1.8 g of protein per kg of body mass (bm) per day (g·kg bm
