Summary
This completed study looked at how the number of meals per day and the timing of energy intake influence gut microbiome composition in both morbidly obese and non-obese adults. Researchers analyzed baseline data from 34 participants (11 non-obese, 23 morbidly obese) to compare their gut bacteria profiles. The goal was to understand whether meal patterns are linked to differences in gut health.
