- Protein yogurt and whey protein both increased skeletal muscle mass and improved strength and gait speed in older adults during an 8-week strength training program, with no significant differences between the groups.
- Whey protein supplementation led to a decrease in fat mass, while protein yogurt supplementation increased resting metabolic rate, indicating some divergent metabolic effects.
- The gut microbiome shifted differently: whey protein increased the Firmicutes/Bacteroidota ratio and enriched Subdoligranulum, whereas protein yogurt enhanced alpha diversity and increased Coprococcus abundance, suggesting distinct gut health impacts.
- Protein yogurt is presented as a cost-effective alternative to whey protein, offering similar muscle gains and additional potential benefits for gut microbiome composition in older adults.
