The other thing to consider is that there are many forms of Type 2 diabetics. Some produce deficient amounts of insulin, so their blood sugar is not well regulated but usually high. There are those that are insulin resistant and make lots of it. As you exercise and lose weight, but insulin response is still high, you might become less insulin resistant and after a big meal (like breakfast), the onslaught of too much insulin gets you hypoglycemic and you may just bonk. In fact, you might fall asleep driving to work in the morning. So it's important to monitor often if this becomes more than an isolated incident. Eat small meals, more frequently and this should help even out sugar levels. But 11 miles might burn about 400 - 500 calories for the average clyde, so it's unlikely you're at any deficit due to lack of food.
