Abstract

Aims/hypothesis Glucagon-like peptide 1 (GLP-1) reduces appetite and energy intake in humans, whereas the other incretin hormone, glucose-dependent insulinotropic polypeptide (GIP), seems to have no effect on eating behaviour. Interestingly, studies in rodents have shown that concomitant activation of GIP and GLP-1 receptors may potentiate the satiety-promoting effect of GLP-1, and a novel dual GLP-1/GIP receptor agonist was recently shown to trigger greater weight losses compared with a GLP-1 receptor agonist in individuals with type 2 diabetes. The aim of this study was to delineate the effects of combined GIP and GLP-1 receptor activation on energy intake, appetite and resting energy expenditure in humans.Methods We examined 17 overweight/obese men in a crossover design with 5 study days. On day 1, a 50 g OGTT was performed; on the following 4 study days, the men received an isoglycaemic i.v. glucose infusion (IIGI) plus saline (154 mmol/l NaCl; placebo), GIP (4 pmol kg-1 min-1), GLP-1 (1 pmol kg-1 min-1) or GIP+GLP-1 (4 and 1 pmol kg-1 min-1, respectively). All IIGIs were performed in a randomised order blinded for the participant and the investigators. The primary endpoint was energy intake as measured by an ad libitum meal after 240 min. Secondary endpoints included appetite ratings and resting energy expenditure, as well as insulin, C-peptide and glucagon responses.Results Energy intake was significantly reduced during IIGI+GLP-1 compared with IIGI+saline infusion (2715 ± 409 vs 4483 ± 568 kJ [mean ± SEM, n = 17], p = 0.014), whereas there were no significant differences in energy intake during IIGI+GIP (4062 ± 520 kJ) or IIGI+GIP+GLP-1 (3875 ± 451 kJ) infusion compared with IIGI+saline (p = 0.590 and p = 0.364, respectively). Energy intake was higher during IIGI+GIP+GLP-1 compared with IIGI+GLP-1 infusion (p = 0.039).Conclusions/interpretation While GLP-1 infusion lowered energy intake in overweight/obese men, simultaneous GIP infusion did not potentiate this GLP-1-mediated effect.Trial registration ClinicalTrials.gov NCT02598791 FUNDING: This study was supported by grants from the Innovation Fund Denmark and the Vissing Foundation.

  • The additive effect of simultaneous GLP-1 and GIP receptor activation on food intake and glycaemia was not observed in some acute clinical studies.

    “despite that this additive effect in food intake and glycaemia was not observed in some acute clinical studies [41, 42].”

    From What is the pipeline for future medications for obesity? (2025) · cites this paper as [42]

    The Discussion (page unavailable) reports that GIP and GLP-1 co-infusion did not lower energy intake more than GLP-1 alone in overweight/obese men. The study maintained isoglycaemic conditions, so it did not directly test whether co-infusion provided an additive improvement in glycaemia; the Results report similar amounts of glucose infused with GLP-1 alone and with co-infusion. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In a study of 17 overweight or obese males, GIP alone had no effect on energy intake.

    “Seventeen overweight or obese males were given either GIP or GLP-1 alone for 5 days, or GIP+GLP-1 at the same time, and allowed to eat ad libitum food 240 min later, and there was no effect on energy intake in the GIP group.”
  • In the same study, combined GIP+GLP-1 administration increased energy intake more than GLP-1 alone (P = 0.039).

    “Energy intake decreased in the GLP-1 administration group, but energy intake increased more in the GIP+GLP-1 combination administration group (P = 0.039) [68].”
  • In the same study, GLP-1 administration decreased energy intake.

    “Energy intake decreased in the GLP-1 administration group, but energy intake increased more in the GIP+GLP-1 combination administration group (P = 0.039) [68].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
