Abstract

Introduction Obesity is frequently a comorbidity of type 2 diabetes. Even modest weight loss can significantly improve glucose homeostasis and lessen cardiometabolic risk factors in patients with type 2 diabetes, but lifestyle-based weight loss strategies are not long-term effective. There is an increasing need to consider pharmacological approaches to assist weight loss in the so called diabesity syndrome. Aim of this review is to analyze the weight-loss effect of non-insulin glucose lowering drugs in patients with type 2 diabetes.Material and methods A systematic analysis of the literature on the effect of non-insulin glucose lowering drugs on weight loss in patients with type 2 diabetes was performed. For each class of drugs, the following parameters were analyzed: kilograms lost on average, effect on body mass index and body composition.Results Our results suggested that anti-diabetic drugs can be stratified into 3 groups based on their efficacy in weight loss: metformin, acarbose, empagliflozin and exenatide resulted in a in a mild weight loss (less than 3.2% of initial weight); canagliflozin, ertugliflozin, dapagliflozin and dulaglutide induces a moderate weight loss (between 3.2% and 5%); liraglutide, semaglutide and tirzepatide resulted in a strong weight loss (greater than 5%).Conclusions This study shows that new anti-diabetic drugs, particularly GLP1-RA and Tirzepatide, are the most effective in inducing weight loss in patients with type 2 diabetes. Interestingly, exenatide appears to be the only GLP1-RA that induces a mild weight loss.

  • Lazzaroni et al. documented a higher (>5%) reduction in weight among T2D patients who were given liraglutide, semaglutide, and tirzepatide.

    “In a recent study by Lazzaroni et al., 61 they documented a higher (>5%) reduction in weight among T2D patients who were given liraglutide, semaglutide, and tirzepatide.”

    From Anti-inflammatory role of glucagon-like peptide 1 receptor agonists and its clinical implications (2024) · cites this paper as [61]

    Sections 4.2 (Liraglutide), 4.4 (Semaglutide), and 4.5 (Tirzepatide; page numbers unavailable) report weight loss exceeding 5% with some doses in studies the paper reviews. The claim overgeneralizes: the paper also reports losses below 5% with other doses, and Lazzaroni et al. reviewed these studies rather than conducting the trials themselves. (LLM, conf=0.87)

  • GLP-1 receptor agonists have significant benefits in weight reduction and can lower the risk of major cardiovascular events, all-cause mortality, hospital admission for heart failure, and worsening kidney function.

    “GLP-1 receptor agonists have been demonstrated to have significant benefits in weight reduction and can also lower the risk of major cardiovascular events, all-cause mortality, hospital admission for heart failure, and worsening kidney function.4,5”

    From Tirzepatide: Clinical review of the twincretin injectable (2023) · cites this paper as [5]

    The Conclusions (page unavailable) identify GLP-1 receptor agonists as the anti-diabetic drug class with the greatest weight-reduction benefit. A passage in Additional information (page unavailable) also describes reduced cardiovascular risk and mortality, but the copy does not establish the specific claims about major cardiovascular events, all-cause mortality, heart-failure admissions, or worsening kidney function.

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.
