Three separate studies examining obesity and related health outcomes have been published in peer reviewed journals.

A study published 7 October in Obesity Science & Practice included 39 adults who had stopped GLP-1 treatment within 30 days.[^1] Mir Ali, MD, stated obesity should be treated as a chronic condition similar to diabetes or hypertension.[^2]

A study published 15 October 2024 in JAMA Network Open found healthy adults with the highest ultra-processed food intake had 1.7% greater body fat and higher odds of vascular brain injury than those with the lowest intake.[^3]

University of Granada researchers published the TEMPUS trial results in Nature Communications, testing intermittent fasting and exercise interventions for adults with obesity.[^4] 187 adults with obesity were randomly assigned to four trial groups over 12 weeks: standard care, fasting only, exercise only, and combined fasting plus exercise.[^5]
