Type 1 diabetics over 50 weight loss

Hey! How are you? My name is Jody. I have been type 1 diabetic for going on 12 years now. I joined myfitnesspal last marvh and stayed with it for about 2 months. Total weight loss was 27 lbs. Then I started slacking off. Well I'm back on the wagon as of yesterday! Really hoping to be able to lose 50 or so pounds! My biggest struggle right now is regulating my insulin pump with my new diet changes. Are you on an insulin pump?
