What kind of diet changes have you tried? Don't try to go too low on calories as that can make your body think it's in starvation mode. Are you at the correct dosage for your meds yet? Sometimes you just have to be patient.

After my diagnosis I gained 60lbs (within a few years) Last year I cut down on sugar with exceptions for iced coffee & tea ^_^ and bread/rice mostly, and exercised more regularly. Mostly biking, walking, and stretching every morning. I lost 40lbs and have been able to maintain it. It still fluctuates a little bit and I don’t expect to lose any more, but I definitely feel better!

Drink more water. Try to eat more fruits and vegetables. If you're southern like me, I know we tend to season foods with meats and bacon grease. Maybe try different spices instead. Pinterest has a lot of good ideas for healthy meals. You dont have to count every calorie, but try to keep it around the right amount for your body type. You can find calorie calculators on google that will help you figure out how many calories you need in a day to maintain or lose weight. I hope this is helpful.
