PRIMARY outcome

Timeframe: baseline (this cross-sectional study involves only one insulin sensitivity measurement in a single visit for each participant)

Population: BMI: 30-40 kg/m2; waist circumference: 88-98cm for women and 100-110cm for men), age: 18-45 years old), weight stable (±3kg for ≥ 6 months), No medications known to affect lipid or glucose metabolism. No evidence and/or history of cardiovascular or metabolic diseases All women were pre-menopausal with regularly occurring menses.

A hyperinsulinemic-euglycemic clamp will be used to assess peripheral insulin sensitivity

Measure
Low Insulin Sensitivity Group
n=10 Participants
Adults with obesity with a rate of glucose disappearance from plasma (Rd Glucose) \< 400 nmol/kg fat free mass/min/(uU/ml Insulin)
High Insulin Sensitivity Group
n=7 Participants
Adults with obesity with a rate of glucose disappearance from plasma (Rd Glucose) \>550 nmol/kg fat free mass/min/(uU/ml Insulin)
Insulin Sensitivity
273 nmol/kg FFM/min /(µU/mL Insulin)
Standard Deviation 54
817 nmol/kg FFM/min /(µU/mL Insulin)

SECONDARY outcome

Timeframe: baseline (this cross-sectional study involves only one Resting Metabolic Rate measurement in a single visit for each participant)

Population: BMI: 30-40 kg/m2; waist circumference: 88-98cm for women and 100-110cm for men), age: 18-45 years old), weight stable (±3kg for ≥ 6 months), No medications known to affect lipid or glucose metabolism. No evidence and/or history of cardiovascular or metabolic diseases All women were pre-menopausal with regularly occurring menses.

Resting metabolic rate was measured using a metabolic cart (to measure VO2 and VCO2) in the morning after an overnight fast
