Welcome to the OMAD forum,
@John O , and I think that you will find a lot of good information here about losing weight and controlling your diabetes with diet change and OMAD.
I also read “The Obesity Code” , by Dr. Jason Fung, and he has one specifically for diabetics called “The Diabetes Code”. You can find both of them on Amazon, and I got the kindle version.
Just changing over to a low carb diet should help your diabetes a lot and once you can start fasting and get the insulin response down and working better, then this is what Dr. Fung says help reverse the diabetes.
If you read some of the great information that is on the main page of this website, it will help answer any questions you might have about starting OMAD, and there is also a lot of important nutrition information in Jimmy’s blog posts.
