Experts Warn 1 in 8 GLP-1 Users Face Undernutrition Risk as Appetite-Suppressing Drugs Cut Intake

Summary
One in eight Americans were using GLP-1 drugs by March 2026, and pharmacists and physicians say the medicines' appetite suppression can leave patients undernourished if food choices are not deliberate.
Harvard's Fatima Cody Stanford said reduced intake can mean too little protein and key micronutrients—especially vitamin D, calcium, iron and B vitamins—raising risks of muscle loss, fatigue, dizziness and lower bone density.
Experts advised small regular meals, high-protein and nutrient-dense foods, hydration, fewer sugary processed foods, and resistance training because the drugs can reduce both fat and lean mass.
Curely pharmacists highlighted foods such as fish, yogurt, legumes, seeds and edamame, while UNC's John Batsis said choices should match tolerance and medical needs, with dietitian support if intake stays very limited.
The guidance frames GLP-1s as one part of obesity and diabetes treatment, with nutrition, exercise and behavioral support still central to sustainable weight loss and overall health.
