If you have diabetes, having a dinner’s worth of calories for breakfast and eating lightly at night could improve your blood sugar numbers. In a small Tel Aviv University study of 18 people with type 2 diabetes, volunteers sugar levels dropped 20% throughout the day when they ate a 704-calorie breakfast and a 205-calorie dinner compared with the reverse. (lunch stayed at 603 calories.) Study subjects also had higher levels of GLP-1, a hormone that helps control appetite and blood sugar, throughout the day.
