Abstract

CONTEXT: The frequency of remission of type 2 diabetes achievable with lifestyle intervention is unclear. OBJECTIVE: To examine the association of a long-term intensive weight-loss intervention with the frequency of remission from type 2 diabetes to prediabetes or normoglycemia. DESIGN, SETTING, AND PARTICIPANTS: Ancillary observational analysis of a 4-year randomized controlled trial (baseline visit, August 2001-April 2004; last follow-up, April 2008) comparing an intensive lifestyle intervention (ILI) with a diabetes support and education control condition (DSE) among 4503 US adults with body mass index of 25 or higher and type 2 diabetes. INTERVENTIONS: Participants were randomly assigned to receive the ILI, which included weekly group and individual counseling in the first 6 months followed by 3 sessions per month for the second 6 months and twice-monthly contact and regular refresher group series and campaigns in years 2 to 4 (n=2241) or the DSE, which was an offer of 3 group sessions per year on diet, physical activity, and social support (n=2262). MAIN OUTCOME MEASURES: Partial or complete remission of diabetes, defined as transition from meeting diabetes criteria to a prediabetes or nondiabetic level of glycemia (fasting plasma glucose <126 mg/dL and hemoglobin A1c <6.5% with no antihyperglycemic medication). RESULTS Intensive lifestyle intervention participants lost significantly more weight than DSE participants at year 1 (net difference, -7.9%; 95% CI, -8.3% to -7.6%) and at year 4 (-3.9%; 95% CI, -4.4% to -3.5%) and had greater fitness increases at year 1 (net difference, 15.4%; 95% CI, 13.7%-17.0%) and at year 4 (6.4%; 95% CI, 4.7%-8.1%) (P < .001 for each). The ILI group was significantly more likely to experience any remission (partial or complete), with prevalences of 11.5% (95% CI, 10.1%-12.8%) during the first year and 7.3% (95% CI, 6.2%-8.4%) at year 4, compared with 2.0% for the DSE group at both time points (95% CIs, 1.4%-2.6% at year 1 and 1.5%-2.7% at year 4) (P < .001 for each). Among ILI participants, 9.2% (95% CI, 7.9%-10.4%), 6.4% (95% CI, 5.3%-7.4%), and 3.5% (95% CI, 2.7%-4.3%) had continuous, sustained remission for at least 2, at least 3, and 4 years, respectively, compared with less than 2% of DSE participants (1.7% [95% CI, 1.2%-2.3%] for at least 2 years; 1.3% [95% CI, 0.8%-1.7%] for at least 3 years; and 0.5% [95% CI, 0.2%-0.8%] for 4 years). CONCLUSIONS: In these exploratory analyses of overweight adults, an intensive lifestyle intervention was associated with a greater likelihood of partial remission of type 2 diabetes compared with diabetes support and education. However, the absolute remission rates were modest. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00017953.

  • A weight reduction of 5% or more brings further health benefits, such as preventing or resolving type 2 diabetes, lowering blood pressure and lipids, improving non-alcoholic fatty liver disease, and alleviating urinary incontinence and sexual dysfunction.

    “Weight loss of this size confers additional health benefits beyond those described above. These include prevention and resolution of type 2 diabetes,11,12 reduction in blood pressure and lipids,13–14 amelioration of non-alcoholic fatty liver disease,15 and improvements in urinary incontinence and sexual dysfunction.16,17”

    From Eight-year weight losses with an intensive lifestyle intervention: The look AHEAD study (2014) · cites this paper as [12]

    The Results report that remission was more common among participants with greater weight loss, including those who lost more than 6.5% of their weight. The Comment reports diabetes-prevention findings from other studies, but this paper studied remission in adults who already had type 2 diabetes; it does not establish a 5% threshold for either outcome. The other listed benefits are attached to different citations in the citing sentence. (LLM, conf=0.84)

  • Several approaches have been reported to elicit T2D remission including surgery, intensive insulin therapy upon diagnosis, and nutrition therapy utilizing significant caloric and/or dietary carbohydrate restriction.

    “Several approaches have been reported to elicit T2D remission including surgery, intensive insulin therapy upon diagnosis, and nutrition therapy utilizing significant caloric and/or dietary carbohydrate restriction [4][5][6][7].”

    From 5-Year effects of a novel continuous remote care model with carbohydrate-restricted nutrition therapy including nutritional ketosis in type 2 diabetes: An extension study (2024) · cites this paper as [5]

    The Abstract and COMMENT report remission following bariatric surgery, and the Intervention and COMMENT describe a calorie-reducing lifestyle program associated with partial or complete remission. The paper does not report remission from intensive insulin therapy upon diagnosis or from dietary carbohydrate restriction; its dietary intervention reduced calories and fat and included physical activity.

    Experimental — accuracy not yet measured
  • Shorter duration of diabetes, lower fasting insulin, and less medication use at enrollment were factors associated with remission in the present investigation, consistent with previous studies.

    “However, shorter duration of diabetes, lower fasting insulin, and less medication use at enrollment were factors associated with remission in the present investigation, consistent with findings reported in previous studies [5,7].”

    From 5-Year effects of a novel continuous remote care model with carbohydrate-restricted nutrition therapy including nutritional ketosis in type 2 diabetes: An extension study (2024) · cites this paper as [5]

    The Results (page not available in our copy) associate remission with fewer years since diabetes diagnosis and not taking insulin at baseline. They do not identify lower fasting insulin as a predictor; the reported measure is lower baseline HbA1c. The medication finding is also narrower than less medication use generally. (LLM, conf=0.88)

  • A fraction of individuals are successful at long-term weight loss maintenance and true disease remission is uncommon.

    “However, a fraction of individuals are successful at long-term weight loss maintenance and true disease remission is uncommon [3, 9].”

    From Effectiveness and Safety of a Novel Care Model for the Management of Type 2 Diabetes at 1 Year: An Open-Label, Non-Randomized, Controlled Study (2018) · cites this paper as [3]

    The Comment section says complete type 2 diabetes remission after intensive lifestyle intervention is rare, and the Results report a low absolute prevalence. The Results also show average weight loss at four years, but do not establish what fraction of individuals successfully maintained long-term weight loss. (LLM, conf=0.85)

  • Intensive lifestyle interventions are effective treatments for obese individuals with T2D when weight loss is achieved and sustained.

    “Intensive lifestyle interventions are effective treatments for obese individuals with T2D when weight loss is achieved and sustained [3].”

    From Effectiveness and Safety of a Novel Care Model for the Management of Type 2 Diabetes at 1 Year: An Open-Label, Non-Randomized, Controlled Study (2018) · cites this paper as [3]

    The COMMENT reports higher remission rates with intensive lifestyle intervention than with diabetes support and education among overweight adults with type 2 diabetes, particularly those with substantial weight loss. But complete remission was rare, and the paper says its four-year follow-up could not fully assess how long remission lasted. It therefore supports a benefit for some patients, not an unqualified claim of effective treatment when weight loss is sustained. (LLM, conf=0.84)

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.
