# GLP-1 therapy requires continuous nutritional monitoring infrastructure but 92 percent of patients receive no dietitian support creating a care gap that widens as adoption scales

GLP-1 receptor agonists suppress appetite as their primary mechanism, reducing caloric intake by 20-30%. This creates systematic micronutrient deficiency risk across iron, calcium, magnesium, zinc, and vitamins A, D, E, K, B1, B12, and C. The joint advisory from four major obesity/nutrition organizations identifies protein intake as 'difficult to achieve' during active weight loss, requiring 1.2-1.6 g/kg/day (versus 0.8 baseline) to preserve lean mass. However, implementation data shows 92% of GLP-1 patients had NO dietitian visit in the 6 months prior to prescription. Only 8.3% had dietitian contact in the 180 days before treatment initiation. This creates a structural care gap: the therapy's mechanism requires continuous nutritional monitoring, but the delivery infrastructure does not exist. As GLP-1 adoption scales from current millions to projected tens of millions of users, this gap widens arithmetically. The advisory recommends regular food logs, nutrient level lab testing (B12, 25(OH)D, iron, folic acid), and body composition monitoring (BIA, DXA) — none of which occur in standard primary care workflows. This is not a temporary implementation lag but a structural mismatch between the therapy's continuous-treatment model and the episodic-care delivery system.
