Metabolic Syndrome, Obesity
Conditions
Brief summary
The purpose of this study is to identify early cardiovascular disease risk factors in those with normal-weight obesity (i.e., normal body, but high body fat percentage) that better track with their long-term cardiovascular disease risk.
Interventions
All participants will be given a high-fat test meal to examine their postprandial triglyceride response.

Intervention model description
3 study groups: control (normal body mass index, low body fat percentage), normal-weight obesity ((normal body mass index, high body fat percentage), and metabolic syndrome
Eligibility
Inclusion criteria
Control group: normal BMI, body fat percentage \< 25% for men and 35% for women Normal-weight obesity group: normal BMI, body fat percentage \> 25% for men and 35% for women Metabolic syndrome group: BMI \> 30 and 2 or more of the following: blood pressure \>130/85 mmHg, fasting glucose \>100 mg/dL, fasting triglycerides \>150 mg/dL, HDL cholesterol \< 40 mg/dL (men) or \< 50 mg/dL (women).
Exclusion criteria
* Presence of pacemaker * Pregnant * use of tobacco products * using lipid lowering drugs
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 4-hour triglycerides after fat tolerance test | Within 2 weeks of study enrollment | Participants will undergo an abbreviated fat tolerance test, where fasting triglycerides are measured, a high-fat shake is consumed, and triglycerides measured once more 4 hours later. 4 hour triglycerides after the high-fat meal is our primary outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Flow-mediated dilation | Within 2 weeks of study enrollment | Flow-mediated dilation is a non-invasive technique to investigate vascular health. This technique will be performed when participants are fasting and \ 4 hours after the shake is completed (just before final measurement of triglycerides) |
| Fasting serum cytokines | Within 10 months of study enrollment | A number of cytokines including GM-CSF, IFN-gamma, IL-1beta, IL-2, IL-5, IL-6, IL-8, IL-12p70, IL-13, IL-17, TNF-alpha, IL-4, IL-10 will be measured as additional cardiovascular disease risk factors. |
