Abstract

The accumulation of an excessive amount of body fat can cause type 2 diabetes, and the risk of type 2 diabetes increases linearly with an increase in body mass index. Accordingly, the worldwide increase in the prevalence of obesity has led to a concomitant increase in the prevalence of type 2 diabetes. The cellular and physiological mechanisms responsible for the link between obesity and type 2 diabetes are complex and involve adiposity-induced alterations in β cell function, adipose tissue biology, and multi-organ insulin resistance, which are often ameliorated and can even be normalized with adequate weight loss.

Claims other papers make about this one

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

  • Obesity reduces quality of life and life expectancy.

    “It has also been shown to reduce both quality of life and life expectancy (2).”

    From The Benefits of Exercise Training in Combination With Weight Loss Therapies (2025) · cites this paper as [2]

    The Introduction describes obesity-related metabolic disease, but does not address quality of life or life expectancy. Its discussion of survival during starvation concerns fasting, not life expectancy; searches for both claimed outcomes found no supporting passage in our copy. (LLM, conf=0.75)

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.
