Three separate peer reviewed studies addressing obesity care and nutrition were published on October 12 2026.

A pilot randomized controlled trial appeared in Obesity Science & Practice. It tested medically tailored meals and digital wellness apps as interventions to slow early weight regain after patients discontinue GLP-1 receptor agonist medications.[^1]

Researchers published separate work in Nature Metabolism characterizing acute metabolic responses to ultraprocessed foods. This study also examined how the brain encodes both the nutritional and monetary value of these foods.[^2]

A third trial, conducted in Italy and published in Frontiers in Public Health, evaluated three months of structured yoga delivered before bariatric surgery. Researchers measured effects on stress hormones and DNA methylation in patients with severe obesity.[^3]

## What this stands on

1. Researchers published a pilot randomized controlled trial in the journal Obesity Science & Practice examining whether medically tailored meals or a digital wellness app could slow early weight regain after discontinuing glucagon-like peptide-1 receptor agonists (GLP-1RAs).
