Overview
Brief Summary
The primary purpose of this research is to demonstrate the therapeutic effects of implementing a well-formulated low carbohydrate lifestyle program over 2 years in patients with type 2 diabetes, pre-diabetes, and metabolic syndrome.
Detailed Description
The primary purpose of this research is to demonstrate the therapeutic effects of implementing a well-formulated low carbohydrate lifestyle program over 2 years. Positive therapeutic effects would be represented by improved glycemic control in patients with type 2 diabetes without use of additional glycemic control medications and failure to progress to type 2 diabetes in individuals with pre-diabetes and metabolic syndrome. Secondary purposes of this research are to determine if therapeutic effects of the intervention differ between patients who self-select onsite vs. web-based education delivery, explore relationships between change in LDL cholesterol and carotid intima media thickness, and to evaluate the sustainability of health outcomes achieved and the economic impact of therapeutic effects over 5 years.

Outcomes
Primary Outcomes
Change from Baseline Body Weight
Time Frame: 3 Months (intervention arms only), 12 and 24 Months (intervention and usual care arms)
Body weight will be evaluated on a calibrated scale
Change from Baseline Type-2 Diabetes Status
Time Frame: 3 Months (intervention arms only), 12 and 24 Months (intervention and usual care arms)
Type-2 diabetes status will be evaluated by measuring Hemoglobin A1c (HbA1c)
Change from Baseline Metabolic Syndrome Status
Time Frame: 3 Months (intervention arms only), 12 and 24 Months (intervention and usual care arms)
Metabolic syndrome status will be evaluated by standard markers. Metabolic syndrome is defined as having at least three of the following: * Waist circumference: ≥40 inches (men) or ≥35 inches (women) * Fasting triglycerides: ≥150 mg/dL * HDL-C: \<40 mg/dL (men) or \<50 mg/dL (women) * Blood pressure: ≥130/85 mm Hg or use of hypertensive medication * Fasting glucose: ≥ 100 mg/dL or use of hyperglycemia medication
Secondary Outcomes
- Change from Baseline Carotid Intima Media Thickness (CIMT) (intervention and usual care arms, participants with type 2 diabetes only)(12 and 24 Months)
- Change from Baseline Serum Lipids(3 Months (intervention arms only), 12 and 24 Months (intervention and usual care arms))
- Change from Baseline Body Composition(3,12 and 24 Months (intervention arms only))
- Change from Baseline Type-2 Diabetes Status(42 and 60 Months (intervention arms only))
- Change from Baseline Metabolic Syndrome Status(42 and 60 Months (intervention arms only))
- Change from Baseline Body Weight(42 and 60 Months (intervention arms only))
