Low glycemic index breakfast reduces calorie intake of preadolescent children according to a recent study from Oxford Brookes University in the United Kingdom. Calories
145 Fewer Calories
When children were fed a low glycemic index foods, they ate 145 fewer calories for breakfast than when they were fed high glycemic index foods.
When they were fed a low glycemic index foods plus sugar (sucrose), they ate 119 fewer calories for breakfast than when they were fed high glycemic index foods.
Sucrose Increased Calories
Sucrose Increased Intake 27 Calories
The children ate an average of 27 more calories for breakfast when sucrose (sugar) was added to the low glycemic index breakfast.
Lunch Calories After Low Glycemic Breakfast
109 Fewer Calories At Lunch Following Low Glycemic Breakfast
After eating a low glycemic index breakfast, children ate 109 fewer calories at lunch.
After eating a low glycemic index breakfast plus sucrose, children ate 83 fewer calories at lunch.
Lunch Calories After High Glycemic Breakfast
36 More Calories At Lunch Following High Glycemic Breakfast
After eating a high glycemic index breakfast, the children ate 36 more calories at lunch.
Subjects: 37 childen, 9-12 Years Old
The study involved 37 children (15 boys and 22 girls) ages 9- to 12-years-old. All children acted as their own controls.
This and other studies suggest that people eat less at a meal and less and the next meal when eating low glycemic index foods.
Glycemic index is the degree to which a given amount of food raises blood sugar levels. High glycemic index foods raise blood sugar levels more than low glycemic index foods.
I would prefer that foods be rated on an insulin index as well as a glycemic index. Some foods, such as fructose, have a very low glycemic index, but raise insulin levels considerably more than would be expected based on their glycemic index.
