Brief summary
Individuals with intellectual developmental disabilities (IDD) have obesity rates that exceed those in the general population, consume energy dense diets, and perform very little physical activity (PA). Overweight and obesity are independent risk factors for chronic disease such as cancer, diabetes, hypertension, and cardiovascular disease in both the general population and those with IDD. The investigators modified the Stop Light Diet (SLDm) to include reduced energy pre-packaged meals (PM) for 6 months, encouraged consumption of low energy shakes and 35 fruits and vegetables (F/V) per week. The investigators will compare participants who use the SLDm with participants who use a reduced energy and fat diet with meal plans, based off of the current American Dietetic Association recommended car for weight reduction plan.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Weight loss between experimental diet (SLDm) and recommended care diet (RC) | Change from Baseline in Weight at 6 months | The experimental diet is the Stop Light Diet modified (SLDm) and includes PM, 35 F/V per week, and low energy shakes. The Investigators will compare this to the RC diet that uses traditional meal plans and includes 35 F/V per week. Weight to be measured following an overnight fast of approximately 12 hours. Weight will be measured in kg. Each person will be weighed in a hospital gown between 8 and 10 am, using a calibrated scale to the nearest 0.1kg. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of chronic disease factors - Blood Pressure | Change from Baseline in Blood Pressure at 18 months | Changes in values of blood pressure between the two groups |
| Comparison of chronic disease factors - Glucose | Change from Baseline in Glucose at 18 months | Changes in values of glucose between the two groups |
| Comparison of chronic disease factors - HDL | Change from Baseline in HDL-cholesterol Pressure at 18 months | Changes in values of HDL-cholesterol between the two groups |
| Comparison of chronic disease factors - LDL | Change from Baseline in LDL-cholesterol Pressure at 18 months | Changes in values of LDL-cholesterol between the two groups |
| Comparison of chronic disease factors - Insulin | Change from Baseline in Insulin Pressure at 18 months | Changes in values of insulin between the two groups |
