Abstract

This study investigated the effect of subcutaneously administered oxyntomodulin on body weight in healthy overweight and obese volunteers. Participants self-administered saline or oxyntomodulin subcutaneously in a randomized, double-blind, parallel-group protocol. Injections were self-administered for 4 weeks, three times daily, 30 min before each meal. The volunteers were asked to maintain their regular diet and level of physical exercise during the study period. Subjects’ body weight, energy intake, and levels of adipose hormones were assessed at the start and end of the study. Body weight was reduced by 2.3 ± 0.4 kg in the treatment group over the study period compared with 0.5 ± 0.5 kg in the control group (P = 0.0106). On average, the treatment group had an additional 0.45-kg weight loss per week. The treatment group demonstrated a reduction in leptin and an increase in adiponectin. Energy intake by the treatment group was significantly reduced by 170 ± 37 kcal (25 ± 5%) at the initial study meal (P = 0.0007) and by 250 ± 63 kcal (35 ± 9%) at the final study meal (P = 0.0023), with no change in subjective food palatability. Oxyntomodulin treatment resulted in weight loss and a change in the levels of adipose hormones consistent with a loss of adipose tissue. The anorectic effect was maintained over the 4-week period. Oxyntomodulin represents a potential therapy for obesity.

  • Oxyntomodulin activates the glucagon receptor and GLP-1 receptor and promotes weight loss through elevated energy expenditure and decreased energy intake in humans.

    “Oxyntomodulin activates the glucagon receptor and GLP-1 receptor and promotes weight loss through elevated energy expenditure and decreased energy intake in humans (Wynne et al, 2005(Wynne et al, , 2006)).”

    From Emerging pharmacotherapies for obesity: A systematic review (2025) · cites this paper as Wynne et al, 2005

    The Results and Discussion report weight loss and decreased energy intake in overweight and obese humans; the Discussion attributes the weight loss to reduced energy intake. Our copy does not establish that oxyntomodulin activates both the glucagon and GLP-1 receptors or that elevated energy expenditure contributed to the weight loss.

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.
