Study information
| Primary study design | Interventional |
|---|---|
| Study design | Single centred randomised controlled trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | Alterations in the macronutrient content of the diet and effects on body composition, cardiovascular disease risk and the control of energy metabolism in obese patients with type II diabetes mellitus |
| Study objectives | To assess the weight loss achieved after 12 months on one of two hypoenergetic low-carbohydrate, high-protein diets (the protein sparing modified fast compared to commercial diet provided by the Go Lower company). |
| Ethics approval(s) | Ethics approval received from the North of Scotland Research Ethics Committees on the 15th April 2008 (ref: 08/S0801/54). |
| Health condition(s) or problem(s) studied | Obese, type 2 diabetics |
| Intervention | Patients will be assigned to either the protein sparing modified fast (PSMF) or the Go Lower diet. In both instances, patients will be given oral and written information about the diet. Patients on Go Lower will be given weekly food packs while the patients on PSMF will prepare their own food. Patients will be seen at 2 and 4 weeks post-randomisation and then monthly for a total of 1 year. |
| Intervention type | Other |
| Primary outcome measure(s) |
Weight change, measured in kilograms at baseline, 3, 6, 9 and 23 months. |
| Key secondary outcome measure(s) |
1. Changes in cardiovascular risk, measured by looking at total cholesterol, triacylglycerols, high density lipoprotein (HDL), low-density lipoprotein (LDL), C-reactive protein (mg/L), fasting glucose (all in mmol/L), fasting insulin (uU/ml), HbA1c (%), waist circumference (cm), blood pressure (mmHg) |
