- Eating a low glycemic index diet helps heart patients to control body weight
- High GI diets can increase the risk of heart disease and type 2 diabetes
- Therefore, consume low GI foods and exclude high GI foods to stay fit and healthy
Glycemic Index Foods
The glycemic index (GI) ranks carbohydrate-containing foods according to how quickly they affect blood sugar levels. High GI foods cause a rapid increase in blood sugar and include white bread, white rice, potatoes and sweets.Effect of Low GI Diet on Body Weight
Observational studies have previously indicated that high GI diets are associated with increased risks of cardiovascular disease and type 2 diabetes. This randomized controlled study assessed the potential benefit of a low GI diet on body mass index (BMI), waist circumference, hip circumference and waist-to-hip ratio in patients with coronary artery disease.Between 2016 and 2019, the study randomly allocated 160 patients aged 38 to 76 years old to three months of either a low GI diet or routine diet. Both groups continued to receive standard therapies for coronary artery disease.
Patients in the low GI group were advised to consume low GI foods and exclude high GI foods while continuing their usual consumption of protein and fat. The routine diet group was advised to consume the recommended diet for coronary artery disease which limits fat and some proteins such as whole milk, cheese, meat, egg yolks and fried foods.
Dietary adherence was assessed with a food frequency questionnaire. Anthropometric indices were measured at baseline and three months.
The average age of participants was 58 years and 52% were women. Anthropometric indices were similar between groups at baseline. At three months, all body measurements had decreased within both groups compared to baseline but the changes were only significant in the low GI group.
- BMI declined by 4.2 kg/m2 in the low GI group compared to 1.4 kg/m2 in the routine diet group.
- Waist circumference decreased by 9 cm in the low GI group compared with 3.3 cm in the routine diet group.
- There was no significant difference between groups for hip circumference and waist-to-hip ratio.
The beneficial effect of a low GI diet on BMI was the same for men and women.
