Metabolic Lab

Take the Lead On promoting health through diet and exercise.

The overall goal of this lab is to reduce the risk for cardiovascular disease, type 2 diabetes, hypertension and obesity through diet and exercise interventions.

Students in the Metabolic Lab conduct research on the effect of diet composition and/or exercise on lipids, lipoprotein particle numbers, glycemic control, endothelial dysfunction, blood pressure, body weight and appetite hormones.  Other research conducted in this lab include the effect of eating behaviors on energy intake and hormones that control appetite and the effect of the eating environment on food choices.

A number of studies conducted in this lab have been in minority populations including Hispanics, African-Americans and South Asians.

Please contact Dr. Meena Shah if you are interested in working in this area.

Laboratory Projects (selected projects)

  • The effects of a ketogenic versus a high-carbohydrate diet on performance, appetite hormones, energy expenditure, and blood lipids in highly trained cyclists
  • Supplement use, dietary intake, sleep quality, and recovery practices of endurance athletes.
  • The relationship between nutrient intakes and sleep quality in endurance athletes.
  • The effect of a prior bout of aerobic exercise versus no exercise on high-sugar meal induced endothelial dysfunction and glycemic responses in postmenopausal women. Endothelial dysfunction was assessed by measuring postprandial flow mediated dilation and nitric oxide and endothelin-1 concentrations.
  • The effect of an acute bout of aerobic exercise versus no exercise on postprandial blood lipids and lipoprotein particle numbers following a high-sugar meal in postmenopausal women.
  • Comparison of nutrient intakes in South Asians with and without type-2 diabetes. The dietary data were collected at UT Southwestern Medical Center and analyzed by TCU students.
  • The effect of a high-protein versus a high-monounsaturated fat meal on postprandial glycemic responses and appetite ratings in obese subjects. Glycemic control was assessed by measuring postprandial glucagon like peptide-1, insulin, glucagon, C-peptide, and glucose responses, and insulin sensitivity.
  • The effect of a high-protein versus a high-monounsaturated fat meal on postprandial blood lipids, lipoprotein particle numbers, leptin, and cytokine responses in obese subjects.
  • The effect of meal composition on postprandial blood lipid and lipoprotein particle numbers in lean subjects.
  • The effect of menu labels, specifically rank-ordered calorie labels, rank-ordered exercise labels, and no labels, on calories and macronutrients ordered and calories from various foods in Hispanic participants.
  • The effect of exercise labels, calorie labels, and no labels on menus on calories and macronutrients ordered and consumed in young adults.
  • The effect of fast versus slow eating speed on hormones that induce hunger (ghrelin) and satiety (glucagon like peptide-1 and peptide YY) and appetite ratings.
  • The effect of slow versus fast eating rate on ad-libitum energy intake and appetite ratings in lean and obese subjects.
  • The effect of plate size on ad-libitum energy intake in lean and obese subjects.
  • Serving size knowledge in African-American women.
  • Predictors of food label use among college students.
  • The relationship between sleep duration, dietary intake, and body mass index among college students.
  • The relationship between exercise and sleep and health related quality of life in breast cancer patients
