Exercise more and regularly. Exercising in the evening is great, especially if the alternative is none. The risk is morning highs, but IMO the DP will happen no matter.
Eat well: Eat food. Not too much. Mostly plants.

Control your weight. You need to watch total calories. Many choose an atkins or high protein low carb diet as this also helps to control sugars. These fill you up and really help with calorie control.
The above too may seem to conflict, but I'm not sure they need to.
Many avoid fruits. I eat lots of fruit but not a lot at once.
Take enough meds to keep your sugars down. You can ween yourself off if the above works out. High sugars are bad. Don't talk yourself into thinking otherwise.
