Absence of an Effect of Liposuction on Insulin Action and Risk Factors for Coronary Heart Disease

Open access

Abstract

Background Liposuction has been proposed as a potential treatment for the metabolic complications of obesity. We evaluated the effect of large-volume abdominal liposuction on metabolic risk factors for coronary heart disease in women with abdominal obesity. Methods We evaluated the insulin sensitivity of liver, skeletal muscle, and adipose tissue (with a euglycemic-hyperinsulinemic clamp procedure and isotope-tracer infusions) as well as levels of inflammatory mediators and other risk factors for coronary heart disease in 15 obese women before and 10 to 12 weeks after abdominal liposuction. Eight of the women had normal glucose tolerance (mean [+/-SD] body-mass index, 35.1+/-2.4), and seven had type 2 diabetes (body-mass index, 39.9+/-5.6). Results Liposuction decreased the volume of subcutaneous abdominal adipose tissue by 44 percent in the subjects with normal glucose tolerance and 28 percent in those with diabetes; those with normal oral glucose tolerance lost 9.1+/-3.7 kg of fat (18+/-3 percent decrease in total fat, P=0.002), and those with type 2 diabetes lost 10.5+/-3.3 kg of fat (19+/-2 percent decrease in total fat, P Conclusions Abdominal liposuction does not significantly improve obesity-associated metabolic abnormalities. Decreasing adipose tissue mass alone will not achieve the metabolic benefits of weight loss.

    It is not known whether one or both of the abdominal subcutaneous and visceral fat depots are actually involved in the pathogenesis of insulin resistance or whether they are simply associated with the metabolic complications of obesity.

    Diet-induced weight loss improves the metabolic complications of abdominal obesity.

    “Diet-induced weight loss improves the metabolic complications of abdominal obesity.”
  • The paper relies on this without support.

    Liposuction does not induce a negative energy balance.

    “Our results suggest that induction of a negative energy balance, not simply a decrease in the mass of adipose tissue, is critical for achieving the metabolic benefits of weight loss.”

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Glucose-tracer dose conversions disagree

    Minor

    The priming dose gives 22.5 μmol for 4.1 mg of the glucose tracer. At that same conversion, the stated 0.46 mg infusion rate corresponds to about 2.5 μmol, not 0.25 μmol, per minute per kilogram.

  • Post-liposuction insulin variability is misconverted

    Minor

    The paper specifies a factor of 6 for converting insulin from μU/ml to pmol/liter. An SD of 6 μU/ml therefore converts to 36 pmol/liter, not the reported 48.

    Reported 48 · recomputed 36

  • Triglyceride estimate lies outside its confidence interval

    Minor

    For the normal-glucose-tolerance group, the reported triglyceride change is −30 mg/dl, but its stated 95% confidence interval runs only from −22 to +2 mg/dl.

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 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-11 (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.
