Just because you don't eat sweets, doesn't mean you are not eating the right foods. Sweets is just a part of it. You have to watch your total carb intake, and the kind of foods you eat. A person could eat a meal including a large potatoe and peas and send their sugar through the roof. Eating a lot of pasta or rice will do the same thing.
Because of my size, 5'6 and currently 169lbs down from 212lbs two years ago, I eat 45 good carbs per meal, three times a day, and 15 good carbs for a snack two to three times a day.
As a snack I eat a yogurt at 13carbs, or a Glucerna shake at 18carbs. I try to eat any fruit with my meals instead as a snack, and it helps with how fast the sugar from the fruit enters my system.
Your sugar levels are definitely dangerously high. I agree with checking with a specialist, and maybe a nutrishionist to help you get a better handle on the proper foods.
