Discontinuing glucagon-like peptide-1 receptor agonists and body habitus: A systematic review and meta-analysis

Open access

Abstract

Summary Research on Glucagon‐like peptide 1 receptor agonist (GLP‐1RA) has mainly focused on the efficacy of weight loss and not the long‐term efficacy of weight loss maintenance. This systematic review and meta‐analysis aims to evaluate the sustainability of weight loss of patients taking GLP‐1RAs following the discontinuation of the drug. EBSCOhost was used to simultaneously search Academic Search Premier, CINHAL Ultimate, Cochrane Central Register of Controlled Trials, MEDLINE with full text, Cochrane Database of Systematic Reviews, and separate PubMed search was systematically investigated using a predetermined search strategy from inception to February 1st, 2024. The authors extracted data regarding body weight change from baseline on treatment and off treatment, change in waist circumference from baseline on and off treatment, and change in BMI from baseline on and off treatment. Meta‐analysis was conducted using RevMan (version 5.4) to calculate pooled mean differences using a Der Simonian‐Laird Random Effects model. ResultsThe initial search yielded 497 relevant articles and, after screening, retained 8 randomized controlled trials comprised of 2372 participants, all with a BMI ≥ 27 kg/m 2 . After discontinuing GLP‐1RA therapy, weight regain was proportional to the original weight loss. Participants who took liraglutide regained 2.20 kg (95% CI 1.69 to 2.70, P < 0.00001), and participants taking semaglutide/tirzepatide regained 9.69 kg (95% CI 5.78 to 13.60, P < 0.00001). This systematic review and meta‐analysis show that significant weight is regained after discontinuing GLP‐1RA treatment, which should be discussed when stopping therapy. Practitioner Points Question: Does discontinuation of Glucagon‐like peptide 1 receptor agonist (GLP‐1RA) treatment lead to significant weight gain? Findings: In this systematic review and meta‐analysis, discontinuing GLP‐1RA treatment led to a pooled overall mean weight regain of 2.20 kg in participants taking liraglutide and 9.69 kg in those patients prescribed semaglutide/tirzepatide. The proportion of weight regained was proportional to the amount originally lost. Meaning: Discontinuation of GLP‐1RA treatment leads to weight regain, regardless of lifestyle interventions, and should therefore be considered a chronic therapy to prevent weight regain and associated undesirable outcomes related to obesity.

TL;DR

This systematic review and meta-analysis of eight randomized trials found that stopping GLP-1 receptor agonists leads to significant regain of weight, waist circumference, and BMI, with larger regain after semaglutide/tirzepatide than liraglutide. The authors conclude these agents should be considered chronic therapy to maintain body habitus benefits.

Key findings

  • Across 8 RCTs (2372 participants, BMI ≥27 kg/m²), discontinuation produced pooled weight regain of 2.20 kg for liraglutide (95% CI 1.69–2.70; P<0.00001; 5 studies, 1572 participants; I²=0%) and 9.69 kg for semaglutide/tirzepatide (95% CI 5.78–13.60; P<0.00001; 3 studies, 800 participants; I²=97%).
  • Waist circumference increased by 1.37 cm after liraglutide cessation (4 studies, 1473 participants; I²=0%) and 5.78 cm after semaglutide/tirzepatide cessation (2 studies, 603 participants; I²=97%).
  • BMI rose by 0.73 kg/m² after liraglutide cessation (3 studies, 438 participants; I²=10%) and 3.59 kg/m² after semaglutide/tirzepatide cessation (3 studies, 800 participants; I²=97%).
  • The amount regained tracked the amount initially lost: liraglutide short-term regained 25.3–29.6% of lost weight and long-term 60.0–163.0%; semaglutide/tirzepatide regained 52.6–63.5%. Semaglutide/tirzepatide regain was clinically significant (6.4–13.1% body weight), while liraglutide regain was not (1.9–2.7% short-term; 1.8–4.6% long-term).

Methods

  • Systematic review/meta-analysis; searched EBSCOhost databases (Academic Search Premier, CINAHL Ultimate, Cochrane CENTRAL, MEDLINE, Cochrane Database of Systematic Reviews) and PubMed from inception to February 1, 2024, plus gray literature and reference lists; two reviewers screened/extracted via Covidence. Inclusion: English RCTs of patients previously on GLP-1RA; exclusions: animal studies, post-bariatric surgery, DPP-4 inhibitors, outcomes without weight.
  • Included 8 RCTs (2372 participants; BMI ≥27 kg/m²): six randomized double-blind controlled trials (1769 in cessation group) and two randomized double-blind withdrawal studies (603 in cessation group). Drugs: liraglutide 3.0 mg (5 studies), semaglutide 2.4 mg (2), tirzepatide 10/15 mg (1); treatment duration 20–160 weeks; follow-up 12, 20–22, 26, 48, or 52 weeks. Lifestyle modification was used in all studies; one stopped lifestyle changes at discontinuation, others continued.
  • Analysis used RevMan 5.4 with DerSimonian-Laird random-effects model to pool mean differences (95% CI); heterogeneity assessed with I²; risk of bias via Cochrane RoB 2.0 (all studies low risk); subgroups by drug and short- vs long-term follow-up.

Limitations

  • Stated: pooled semaglutide/tirzepatide analyses had considerable heterogeneity (I²=97%); stepwise removal showed Rubino et al. had largest influence, and removing it reduced I² to 0% for weight and BMI. Authors attribute possible difference to follow-up length (52 vs 48 weeks) and unequal representation of semaglutide/tirzepatide versus liraglutide.
  • Stated: only two semaglutide/tirzepatide studies reported waist circumference, so time-off-treatment effects could not be meta-analyzed; DerSimonian-Laird method cannot reliably estimate heterogeneity with few studies; adherence to lifestyle interventions was not consistently reported, which likely affects regain.
  • Evident from text: some outcomes rested on few studies (2–3), one included trial had only 15 participants, and the review included both pediatric and adult populations with different comorbidities, which may limit generalizability. The search was also restricted to English and 2015 onward.

  • The paper relies on this without support.

    Participants in the included studies adhered to the lifestyle interventions during off-treatment periods sufficiently to test whether weight regain occurs despite lifestyle changes.

    “Thus, if participants continued lifestyle modifications as they were encouraged to do, they theoretically should have been able to keep the weight off.”
  • The paper relies on this without support.

    The withdrawal or placebo groups in the included randomized trials are a valid proxy for real-world discontinuation of GLP-1 receptor agonists.

    “These studies randomized participants to continue treatment with GLP-1RA or a placebo injection with subsequent patient follow-up.”
  • The paper relies on this without support.

    The populations in the included trials are representative of patients who discontinue GLP-1 receptor agonists in clinical practice.

    “While all articles had participants who were obese or overweight, each article focused on a specific comorbidity, which included either type 2 diabetes, 20 pre-diabetes, 21 obesity, 5,12,19,22,23 or obesity with non-alcoholic fatty liver disease.24”
  • The paper relies on this without support.

    How well patients follow prescribed lifestyle changes probably affects how much weight they regain after stopping GLP-1 receptor agonists.

    “This is a significant limitation, as adherence to prescribed lifestyle changes likely influences weight regain after GLP-1RA discontinuation.”
  • The paper relies on this without support.

    A six-week difference in follow-up length is not expected to be clinically important.

    “We did not expect 6 weeks to make a clinically significant difference.”

    Study 23 is cited among the studies that stopped lifestyle modifications during follow-up and among those that continued them.

  • Figure 3b is labeled with the wrong body-size measure

    Minor

    The results identify Figure 3b as the liraglutide BMI analysis, while its caption describes a waist-circumference analysis in centimetres.

  • The publication-date range excludes an included study

    Minor

    The stated publication range ends in December 2023, but the study-characteristics table identifies an included study as published in 2024.

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.

A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
