Eligibility

Inclusion Criteria:

• Obese men and women with pre-diabetes; (BMI 30-40 kg/m2)

• Ages ranging from 30-60 years old;

• Individuals with:

• impaired fasting glucose (IFG), (between 100-125mg/dl, with post-prandial glucose (<140 mg/dl 2 hrs after 75g OGTT)

• impaired glucose tolerance (IGT), (normal fasting glucose <100mg/dl, with post-prandial glucose (>140 mg/dl 2 hrs after 75g OGTT)

• a combination of the two (IFG/IGT) (both impaired fasting glucose (100-125mg/dl), and impaired glucose tolerance (>140 mg/dl 2 hrs after 75g OGTT), will be verified using oral glucose tolerance testing at initial screening, and

• Sedentary (<2 hours/week of planned physical activity).

To increase generalizability, and because each subject serves as their own control, women will be enrolled regardless of menopausal status, use of hormone replacement therapy and oral contraceptives.

Exclusion Criteria:

• Regular exercise more than 2 hours/week,

• medications that could affect glucose,

• lipid metabolism,

• thyroid disease,

• history of lung disease,

• pregnancy,

• active cigarette smoking or exposure to second hand smoke, and

• Severe plasma lipid disorders.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in insulin sensitivity	Change in insulin sensitivity measured before and after the 3 month weight loss and exercise training intervention	baseline and 3 months
Secondary	Change in membrane localized diacylglycerol species	Change in concentration of membrane and cytosolic diacylglycerol species before and after the intervention. Diacylglycerol is a lipid known to be related to insulin resistance.	baseline and 3 months
