Hello,
May I ask what is 'the right diet" that you are eating? People with diabetes have an inability for their body to handle carbohydrates. Therefore, one of the best ways to address this is to restrict carbs.
The best diet for people with diabetes, if you are using diet alone to control your condition, is one consisting of very low carb intake; avoiding sugars, sweet fruits, and grains and sticking with carbs mostly from vegetables along with quality protein and fat sources.
