Summary

Obese patients with type 2 diabetes often fail to loose weight and thus do not succeed in improving their sugar and lipid profiles and remain at high risk for diabetes complications The study enrolled 259 obese diabetic patients attending HMO clinics in central Israel. Over a 6 month period the participants met with a dietitian every fortnight and attended group lectures every 2 months. The objective of this intervention was to compare three dietary intervention along with close monitoring of the patients by dietitians, regarding blood lipid and sugar balance as well as weight loss. The three diets are the American Diabetes Association (ADA) diet from 2003; a diet containing low glycemic index carbohydrate otherwise similar to the ADA diet; and a low glycemic index diet with more fat than the other 2 diets with high proportion of mono-unsaturated fatty acids. Patients were individually randomized to receive one of the three diets. Among the measures obtained every 3 months for the first year and every 6 months thereafter are weight, fasting insulin and glucose, glycosylated hemoglobin, blood and urine chemistry profiles and lipid profile.

Type	Name	Description
BEHAVIORAL	MUFA diet	Patients were advised to consume 23 cal/kg/day. The diet contained sodium (up to 3000mg/day), potassium (more than 3000 mg/day), calcium (around 1300 mg/day) and magnesium (more than 800 mg/day). MUFA diet included only low glycemic index carbohydrates. The diet consisted of 35% carbohydrates and 45% fat (50% of them were mono-unsaturated fatty acids \[MUFA\]). Participants were advised to eat 4-6 meals per day according to their lifestyle and to participate in 30-45 min of aerobic activity at least 3 days a week.

The diet contained sodium (up to 3000mg/day), potassium (more than 3000 mg/day), calcium (around 1300 mg/day) and magnesium (more than 800 mg/day). The carbohydrates are with mixed glycemic index. The diet contains 50-55% carbohydrates, 30% fat and 15-20% protein. Participants were advised to eat 4-6 meals per day according to their lifestyle and to participate in 30-45 min of aerobic activity at least 3 days a week.
BEHAVIORAL	Low Glycemic index (LGI) diet	Patients were advised to consume 23 cal/kg/day. The diet contained sodium (up to 3000mg/day), potassium (more than 3000 mg/day), calcium (around 1300 mg/day) and magnesium (more than 800 mg/day). LGI diet included only low glycemic index carbohydrates. The diet consisted of 50-55% carbohydrates, 30% fat and 20%. protein.
