GLP-1 drugs mimic a hormone the body releases when you eat that tells you "I am full". The result is you eat quite a bit less, effortlessly. But eating little is not the same as eating well: with less food, each bite has to deliver more nutrients. The goal shifts from "eat less" to "make the little you eat count", especially in protein.
Priorities when you have almost no appetite
| Priority | Target | Why |
|---|---|---|
| Protein | 1.2-2 g/kg per day | Preserve muscle while losing weight |
| Small meals | 3-5 per day | Better tolerance, less nausea |
| Water | Constant, in sips | Prevents dehydration and constipation |
| Vegetables and fibre | Every meal | Satiety, digestion, micronutrients |
| Fat/fried | Moderate | They worsen nausea |

Mistakes worth avoiding
- Eating so little you do not even reach the minimum protein (you lose muscle).
- Skipping meals entirely instead of having small portions.
- Forgetting water: low appetite also reduces the urge to drink.
- Filling up on soft ultra-processed food "that goes down easily" instead of real food.
- Not training strength: muscle is kept by using it, not just by eating protein.
In short: GLP-1 removes the hunger, but not the responsibility to nourish yourself. Use it as a window to build habits: enough protein, vegetables, hydration and strength. That way you lose fat (not muscle) and arrive prepared for the day you stop the drug. Lean on your doctor for the clinical side and on Renzy to make sure that, with the little you eat, you cover what matters.
