Figure 5. GLP-1 Receptor Knockout Eliminates Dual GIP/GLP-1 Receptor Agonism-Induced Preference Shift between 5-Day Choice Chow and 60% High-Fat Diet (HFD) in Mice.
Effect of once daily injections [vehicle or tirzepatide (TZP)] in wildtype (WT) and GLP-1 receptor knockout (KO) mice on daily intake of chow (A) and 60% HFD (B). Five-day cumulative intake of chow (C), intake of 60% HFD (D), and body weight change (E). Daily average intake of chow and 60% HFD as Kcals (F) and as a percentage of total Kcal intake (G). Direct comparisons are indicated with letter sets (a,b or x,z). N=4–6 per treatment group.
