@Mythopoeika , I hope you don't mind me over explaining your comment as a response to some comments following it.
My husband became diabetic (insulin dependent) later in his life. When he would have his supper at 1600. We never ate supper together cuz I wasn't even home from work. He would then usually have cereal later before bed.
He still had problems with low blood sugar levels throughout the night.
Just to clear an unspoken assumption that I noticed in prior comments - a pancreas that is not producing insulin as needed by your body, or your body's inability to absorb the insulin properly causes you to become diabetic. Excess body fat can cause you to become diabetic, but this is not the only factor. Not everyone who is diabetic is overweight.
Also if you become insulin dependent, the insulin can cause you to put on weight.
Mytho's comment refers to the schedule of eating numerous small meals throughout the day to maintain a steady level of insulin in your blood.
