About this trial
This research study collects health-related information and blood samples to better understand how body composition, lifestyle habits, and diet influence meta-inflammatory monocytes (MiMos) in adolescents. The hypothesis of this study is that adolescents at risk for metabolic disease have enhanced MiMo related activities leading to insulin resistance.

Trial outcomes
Primary outcomes
Glucose (OGTT)
Plasma Glucose (mg/dL) will be measured prior to, and throughout, an Oral Glucose Tolerance Test (OGTT). Measurements will be taken at baseline (fasting) and 30, 60, 90 and 120 minutes after consumption of glucose dose
Insulin (OGTT)
Plasma Insulin (µU/mL) will be measured prior to, and throughout, an Oral Glucose Tolerance Test (OGTT). Measurements will be taken at baseline (fasting) and 30, 60, 90 and 120 minutes after consumption of glucose dose
Glucose (MMTT)
Plasma Glucose (mg/dL) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake.
Insulin (MMTT)
Plasma Insulin (µU/mL) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake.
Secondary outcomes
Free fatty acids (MMTT)
Serum Free fatty acids (mmol/L) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake
Triglycerides (MMTT)
Serum Triglycerides (mg/dL) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake
