13. Metabolic predictors of obesity. Contribution of resting energy expenditure, thermic effect of food, and fuel utilization to four-year weight gain of post-obese and never-obese women.
This prospective study was designed to identify abnormalities of energy expenditure and fuel utilization which distinguish post-obese women from never-obese controls. 24 moderately obese, postmenopausal, nondiabetic women with a familial predisposition to obesity underwent assessments of body composition, fasting and postprandial energy expenditure, and fuel

14. Thermic effect of glucose in man. Obligatory and facultative thermogenesis.
The contribution of the sympathetic nervous system to the thermic effect of intravenously infused glucose and insulin was studied in 10 healthy young men before and after beta-adrenergic receptor blockade with propranolol during conditions of normoglycemia (90 mg/dl) at two levels of hyperinsulinemia (approximately 90 microU/ml and approximately 620 microU/m

15. Thermic effect of food at rest, during exercise, and after exercise in lean and obese men of similar body weight.
The thermic effect of food at rest, during 30 min of cycle ergometer exercise, and after exercise was studied in eight lean (mean +/- SEM, 10 +/- 1% body fat, hydrostatically-determined) and eight obese men (30 +/- 2% body fat). The lean and obese mean were matched with respect to age, height, weight, and body mass index (BMI) to determine the relationship b

16. Activity Energy Expenditure and Mobility Limitation in Older Adults: Differential Associations by Sex
In this study, the authors aimed to determine whether higher activity energy expenditure, assessed by using doubly labeled water, was associated with a reduced decline in mobility limitation among 248 older community-dwelling US adults aged 70–82 years enrolled in 1998–1999. Activity energy expenditure was calculated as total energy expenditure (assessed

17. Independent effects of obesity and insulin resistance on postprandial thermogenesis in men.
The putative blunted thermogenesis in obesity may be related to insulin resistance, but insulin sensitivity and obesity are potentially confounding factors. To determine the independent effects of obesity and insulin resistance on the thermic effect of food, at rest and after exercise, lean and obese men were matched at two levels of insulin sensitivity dete

18. Thermic effect and substrate oxidation in response to intravenous nutrition in cancer patients who lose weight.
This study examined oxidative metabolism and thermogenesis in the acute response to controlled intravenous nutrition in seven cancer patients who lost weight. Six weight-losing and malnourished patients without cancer served as controls. Indirect calorimetry was used and measurements of arterial concentrations of various substrates, metabolic end products, a
