People with type 2 diabetes have to keep a close watch on their blood glucose levels. Now a small study finds that having the day's biggest meal at breakfast and a smallest meal at dinner offers much better than glucose control than having a small breakfast and big dinner even when the total intake during the day was exactly the same 1,500 calories. The study by the researchers from Israel's Tel Aviv University, sweden's Lund University and other institutions, is in the journal Diabetologia.
18 adult volunteers, 10 women and 8 men, all with type to 2 diabetes, were assigned by coin-flip to either bigger breakfast style or the bigger dinner one.
In the bigger dinner diets, participants spend a week haveing about a 200 calorie breakfast,a 600 calorie lunch and 700 calorie dinner. The bigger breakfast diet was the reverse, with the 700 calorie meal in the morning, the 600 calorie lunch and a light 200 calorie dinner.
After two weeks, the groups switched meal plans. so that the big dinner floks became the big breakfast floks, and vice versa. And overall, various measures of blood glucose and insulin levels were significantly better in those who had their big meal in the morning. |
