My 22 year old daughter was just diagnosed with diabetes in August.
I am SO proud of her-she lives on her own, and she took charge of her needs as soon as she learned she has it. She's lost about 30 pounds, and her sugar has stablized. Her doctor is even switching her to pill form instead of shots in a couple of months.
If you don't get any other answers from others, I could find out from her and let you know (private message me if you would like), but she really hasn't changed too much what she eats, but more, how much she eats. She does steer clear of sugar quite a bit more, and also pasta.
I think meats and veggies are mostly good, so you should still be able to make a lot of satisfying meals.
Hope this helps a little! And hopefully he'll cool down shortly-it's built into men to be strong-that's probably why he's in denial. Fortunately, as I'm seeing with my daughter, the diabetes doesn't have to control a person's life. She feels better than she has in a long, long time, and she's very active and enjoying life!
