Abstract

Background: Behavioral weight management programs (BWMPs) enhance weight loss in the short term, but longer term cardiometabolic effects are uncertain as weight is commonly regained. We assessed the impact of weight regain after BWMPs on cardiovascular risk factors, diabetes, and cardiovascular disease. Methods: Trial registries, 11 databases, and forward-citation searching (latest search, December 19) were used to identify articles published in English, from any geographical region. Randomized trials of BWMPs in adults with overweight/obesity reporting cardiometabolic outcomes at ≥12 months at and after program end were included. Differences between more intensive interventions and comparator groups were synthesized using mixed-effects, meta-regression, and time-to-event models to assess the impact of weight regain on cardiovascular disease incidence and risk. Results: One hundred twenty-four trials reporting on ≥1 cardiometabolic outcomes with a median follow-up of 28 (range, 11–360) months after program end were included. Median baseline participant body mass index was 33 kg/m 2 ; median age was 51 years. Eight and 15 study arms (7889 and 4202 participants, respectively) examined the incidence of cardiovascular disease and type 2 diabetes, respectively, with imprecise evidence of a lower incidence for at least 5 years. Weight regain in BWMPs relative to comparators reduced these differences. One and 5 years after program end, total cholesterol/HDL (high-density lipoprotein) ratio was 1.5 points lower at both times (82 studies; 19 003 participants), systolic blood pressure was 1.5 mm mercury and 0.4 mm lower (84 studies; 30 836 participants), and HbA1c (%) 0.38 lower at both times (94 studies; 28 083 participants). Of the included studies, 22% were judged at high risk of bias; removing these did not meaningfully change results. Conclusions: Despite weight regain, BWMPs reduce cardiometabolic risk factors with effects lasting at least 5 years after program end and dwindling with weight regain. Evidence that they reduce the incidence of cardiovascular disease or diabetes is less certain. Few studies followed participants for ≥5 years.

  • The benefits of weight loss on diabetes and other cardiovascular disease risk markers were attenuated by weight regain.

    “The benefits of weight loss on diabetes and other cardiovascular disease risk markers were, however, attenuated by weight regain.10”

    From Weight regain after cessation of medication for weight management: systematic review and meta-analysis (2026) · cites this paper as [10]

    The Discussion (page unavailable) reports that weight regain reduced improvements in cardiometabolic risk factors, but explicitly excepts glycemic control. The Results (Effects of Interventions; page unavailable) found no evidence of an association between weight regain and glycemic control, so the claim overgeneralizes the attenuation to diabetes-related markers. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Our systematic review of weight change in randomized controlled trials after the cessation of behavioral weight management programs estimated weight regain to be between 0.12 and 0.32 kg/year.

    “Indeed, our systematic review of weight change in RCTs after the cessation of behavioral weight management programs estimated weight regain to be between 0.12 and 0.32 kg/year.”

    From The societal implications of using glucagon-like peptide-1 receptor agonists for the treatment of obesity (2025) · cites this paper as [81]

    The What the Study Adds section reports weight regain of 0.12–0.32 kg/year after program end, depending on the model. That estimate is explicitly *more than the comparator group*, a qualifier the citing sentence omits. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • A review of behavioral weight management programs found benefits for cardiometabolic health lasting approximately 5 years after program end, which has so far not been indicated following the cessation of weight loss using the new pharmacological agents.

    “A review of behavioral weight management programs found benefits for cardiometabolic health lasting ∼5 years after program end, which has so far not been indicated following the cessation of weight loss using the new pharmacological agents.”

    Experimental — accuracy not yet measured
  • Counselling by a dietitian and/or implementation of weight management programs is associated with improvements in cardiometabolic risk factors including reductions in dyslipidemia (total cholesterol, low-density lipoprotein and triglycerides), blood pressure, glycosylated hemoglobin, fasting blood glucose and insulin resistance.

    “other studies have reported improvements in risk factors for cardiometabolic disease including reductions in dyslipidemia (total cholesterol, low-density lipoprotein and triglycerides), blood pressure, glycosylated hemoglobin, fasting blood glucose and insulin resistance following counselling by a dietitian and/or implementation of weight management programs [[104], [105], [106]].”

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.
