Two separate published studies have reported new findings relevant to clinical weight and sleep management.

A research review published 2025-09-03 in JAMA Otolaryngology found that GLP-1 receptor agonists may offer significant improvement in obstructive sleep apnea related to obesity [^1]. Zepbound, or tirzepatide, is currently the only weight loss medication that holds FDA approval for the treatment of moderate to severe obstructive sleep apnea in adults with obesity [^2].

A 2026 randomized controlled trial published in the British Journal of Nutrition found no statistically significant difference in two year weight loss between participants drinking diet beverages and those drinking water [^3].
