I was diagnosed with type2 in Jan of 2017, doctor was glad to write an Rx for metformin and send me home. I decided not to fill the script and try totally changing my diet first. Came back 3 months later and she was very pleased with the results and said the Metformin was working. I said "No actually I never filled it" The look on her face was priceless. She said I have to eat a lot of carbs at every meal and she will keep me covered with meds. I said "no thanks" and changed doctors.
My new doc told me that he doesn't care what I am doing, my results are good so keep it up. All I really did was cut out carbs, sort of like a keto diet without going overboard on the fat. Not only did I lose weight but my A1C has been good for years. I do sometimes eat horrible desserts, but truly once in a while. As long as I watch my carbs 95% of the time I have no issues with blood sugar numbers anymore. I read somewhere that the definition for type 2 Diabetes may not be correct and it is more of a carb intolerance than an actual disease. I tend to agree with that from my experience.
BUT everyone is different and you have to check your sugar and find out what works for you. I tolerate fruit very well, but give me corn or rice and my sugar shoots up. Potatoes are out of the question but sweet potatoes don't affect me much. You have to dial in what works for you and it takes time. Basically what it comes down to is cut out the carbs and the diabetes goes away. It isn't that difficult to live off of meat, cheese and veggies. If you get creative there are many really delicious foods that you can make that work with your diet so you don't feel left out. The secret is looking into the amount of carbs in everything. Certain things have tons of carbs and you wouldn't expect them to, like dairy.
