Abstract

Obesity causes serious medical complications and impairs quality of life. Moreover, in older persons, obesity can exacerbate the age-related decline in physical function and lead to frailty. However, appropriate treatment for obesity in older persons is controversial because of the reduction in relative health risks associated with increasing body mass index and the concern that weight loss could have potential harmful effects in the older population. This joint position statement from the American Society for Nutrition and the NAASO, The Obesity Society reviews the clinical issues related to obesity in older persons and provides health professionals with appropriate weight-management guidelines for obese older patients. The current data show that weight-loss therapy improves physical function, quality of life, and the medical complications associated with obesity in older persons. Therefore, weight-loss therapy that minimizes muscle and bone losses is recommended for older persons who are obese and who have functional impairments or medical complications that can benefit from weight loss.

  • With ageing, fat preferentially accumulates viscerally and ectopically rather than as abdominal subcutaneous fat.

    “With ageing, fat preferentially accumulates both viscerally and ectopically rather than as abdominal subcutaneous fat.”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [186]

    The 'Changes in body weight and body composition with aging' section says intraabdominal fat increases more, in relative terms, than subcutaneous fat. It also reports increases in intramuscular and intrahepatic fat, but does not say those ectopic depots increase preferentially over abdominal subcutaneous fat; the 'Definition of obesity' section says abdominal subcutaneous fat also increases with aging. Page numbers were not available in our copy. (LLM, conf=0.86)

  • Rapid intra-abdominal fat accumulation is worsened by physical inactivity, hormonal changes, reduced responsiveness to thyroid hormone and leptin resistance.

    “Rapid accumulation of intra-abdominal fat is exacerbated by physical inactivity, hormonal changes, reduced responsiveness to thyroid hormone and leptin resistance186.”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [186]

    The Pathogenesis section links declining physical activity and age-related hormonal changes, including reduced thyroid-hormone responsiveness and leptin resistance, to increasing body fat. The Changes in Body Weight and Body Composition with Aging section reports a greater relative increase in intra-abdominal fat. The paper does not specifically establish that each listed factor worsens intra-abdominal fat accumulation, and it describes the overall increase in body fat as gradual, not rapid. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Intentional weight loss in older adults improves morbidity and physical function.

    “intentional weight loss in older adults improves morbidity and physical function186”

    From Sarcopenic obesity in older adults: aetiology, epidemiology and treatment strategies (2018) · cites this paper as [186]

    The Physical function and quality of life section reports improved physical function in obese older adults when moderate weight loss was combined with exercise. The Medical complications section reports improvements in obesity-related metabolic abnormalities, but says most studies of these effects were conducted in middle-aged adults; it does not establish improved morbidity in older adults. The claim also omits the exercise component of the physical-function finding. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • It has been recommended that fried and high-fat foods be avoided to decrease gastrointestinal side effects associated with AOMs.

    “It has been recommended that fried and high-fat foods be avoided to decrease gastrointestinal side effects associated with AOMs [71,72].”

    From Nutritional considerations with antiobesity medications (2024) · cites this paper as [71]

    The Pharmacotherapy section reports gastrointestinal side effects from orlistat, an anti-obesity medication, and explains that it increases stool fat. It does not recommend avoiding fried or high-fat foods to reduce those side effects. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Obesity is defined as unhealthy excess body fat that increases the risk of medical illness and mortality.

    “Obesity is defined as an unhealthy excess body fat that increases the risk of medical illness and mortality186.”

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.
