Hello Roberto and thanks for bringing such an important question to the Disney Parks Moms Panel.
My husband is also a diabetic and we just love eating on the Disney Dining Plan during our trips to Walt Disney World Resort, so I completely understand both your dietary concerns and thriftiness at not wanting any delicious desserts to go to waste.
Please don't concern yourself any further because my husband has always been able to find an indulgent and tasty
sugar free or
low sugar dessert option on most menus at Walt Disney World Resort. You will find these options clearly marked on each Disney restaurant menu.
Another
top tip is to seek out the knowledgeable advice of the Cast Member serving you or if wished it's usually possible to discuss any dietary concerns you may have with a restaurant Chef.
This link also provides a great source of information -
Special Dietary Requests.
If I can help further plan your upcoming vacation to Walt Disney World Resort please pop back to ask me another question.
Have a great Disney day.
- Jane
