Try exercising, drink lots of water, keep your blood suagrs under control, make sure you eat 4-6 meals instead of one or two "big" meals( if you dont eat enough during the day your body thinks your trying to starve it and will store your fat instead of burning it off), eating more smalller meals will helps this and will as well help you blood sugars

Atkins or some other low carb diet could be tried

Please don't get down and out about this. I have type 1 diabetes too and I am nobody special. I am not one of those naturally thin women and I have struggled with being overweight all my life. Some years ago I managed to get myself to a good weight by medication. Then, a little over a year ago I was diagnosed with this crazy disease. (diabetes) now...I don't really exercise...Unless you call taking care of 3 kids exercise. I don't follow some special diet...Which is probably not such a good thing. I am no more active than most people. I do eat a lot of healthy things...Just because I like fruits and veggies. I probably put away more carbs than a football team. A few months ago I weighed 113 lbs....At 5'9"...That was what my mom likes to say....Like being a bag of bones. Now I am to a good weight and trying to stay there. You have probably read that diabetics tend to be overweight...At least that is what I have read...But, that isn't the case. Like I said, i'm nobody special and I don't do anything special. It is very possible to have this disease and not be overweight. I just wanted you to know that if I can have diabetes and control my weight then anyone can. You'll find your niche and it will turn out better than you expected.
