The glucose meter spikes after a meal the way the person on GLP-1 least expects. Beans, 🌾 oats, yogurt, 🥚 eggs, 🫘 lentils, potatoes, fruit, rice, vegetables, and balanced meals often produce more gradual glucose responses than sugary drinks, pastries, or ultra-processed snacks.
Liquid carbohydrates are absorbed quickly, which is why sugary drinks often raise blood sugar rapidly. GLP-1 receptor agonists already slow gastric emptying which usually helps blood sugar rise more gradually after meals. Large amounts of refined sugar can still produce rapid glucose rises on GLP-1 because the slowing effect has limits.
Fiber usually helps blood sugar rise more gradually because it slows glucose absorption after eating. Protein and fat can help reduce sharp post-meal glucose spikes by slowing gastric emptying and glucose absorption.
