Participants
T2D adults were recruited from the Iranian Diabetes Society (IDS), Tehran, Iran. Inclusion criteria were adults (aged 25-60 years) diagnosed with T2D for at least two years on lipid-lowering medications (e.g., Statins, Nicotinic acid). They had taken part in regular diabetes education classes, including carbohydrate counting. People with diabetes complications (retinopathy, nephropathy, and neuropathy), CVD (cardiovascular diseases) or other conditions that may prevent class attendance, taking medications that affect lipid levels such as antipsychotics (e.g., Clozapine), and alcohol drinkers (consume beer, wine, liquor, or hard liquor beverages at least once per week for a minimum of 6 months (Lee et al., 2007)) were ineligible.
