How this works

Every item is rated for people on weight loss injections. We focus on protein content (to preserve muscle), fat levels (the #1 nausea trigger on GLP-1s), portion size, and stomach-friendliness. Data sourced from official UK chain nutrition guides and verified against FatSecret UK. 17 of 20 chains verified. Updated March 2026.

Why trust this guide?

We found that third-party nutrition databases consistently underestimate UK portion sizes — sometimes by 30-40%. So we went to the source. Four chains verified against official UK PDFs (KFC, Greggs, Subway, McDonald's), thirteen more cross-referenced with FatSecret UK data. Every item shows its verification status. If we're not sure, we tell you.
