Hey there, and good morning to you!
What do they need to do in regards to their diet?
They would need to eat a healthy, low-fat diet, with low sugars. Especially added sugars, you would want to exclude those. By doing so, your blood sugar would be balanced, and your body could handle the lack of insulin better. (insulin is what regulates blood sugar, but when you have diabetes, you don't have a large supply) Try to eat a lot of fibers, and not to focus so much on carbs- but more filling and satisfying healthy fats and foods.
I hope this helps!
