GLP-1 diet recommendations

You are trying to eat well on a much smaller appetite.

Reference and calculator, not medical advice. This page explains how something works; it does not tell you what to take. Last reviewed August 2026.

The eating problem on a GLP-1 is capacity, not restraint. Appetite drops and gastric emptying slows, so getting adequate protein and micronutrients into a much smaller volume becomes a planning problem.

Two practical consequences follow from that. Anything you need daily has to fit inside a much smaller total volume, so nutrient density stops being an optimisation and becomes the constraint. And appetite is not steady across the week — it is typically lowest in the days after a dose increase, which is exactly when it is easiest to under-eat without noticing.

Common questions

Why does protein get so much attention here?
Weight lost in a large calorie deficit includes lean mass as well as fat. Protein intake and resistance training are the two levers generally cited for limiting that. The difficulty on a GLP-1 is mechanical — hitting a protein target when you are full after a few bites is a planning problem, not a discipline one.
Which foods tend to cause the most trouble?
Reports cluster around high-fat and fried foods, large volumes at a single sitting, and alcohol. That is consistent with slowed gastric emptying, though individual tolerance varies widely.
Does appetite come back if I stop?
The medication works while it is being taken. What happens afterwards depends on why you started and is a question for your prescriber.

Sources and last review

This page is general reference rather than a dosing table, so it quotes no figures from a label. Nothing here is reviewed by a clinician, and this site does not employ one — which is exactly why what I do publish stays traceable to its source.
