Like others have already said, there's nothing to fear about meeting with a dietitian. Any of their recommendations you accept is totally your choice. It's important that the dietitian understands and uses your current food preferences to work out a meal plan for you.
Many of us long-term diabetics have found past doctrinaire offered by dietitians who closely followed their professional association's guidance regarding the amount of carbohydrates in the diet as unworkable for someone with an impaired glucose metabolism. Carbohydrates determine the amount of insulin needed to metabolize, whether that insulin is home-grown or taken as an injection.
While we are all different in our metabolisms, many of us have found that limiting carbs can have a profoundly positive effect on our post-meal blood sugar levels. In the past, dietitians have often recommended consuming 50% or more of our daily calories as carbohydrates. As part of a 2000 calories/day plan means eating 250 grams of carbs/day. For me, that level of carb consumption increases the amount of insulin I need to dose, drives up glucose variability, and exposes me to increased hyper- and hypo-glycemia.
Good luck with your dietary consult. I think we all can learn more about what we eat. The most powerful tactic for learning how to eat with diabetes is one called "eat to your meter." It simply means measuring your blood glucose with a fingerstick meter before and two hours after you eat. If you don't like the post-meal check, then alter the serving size or possibly eliminate that food from your diet. It's a customized system that puts you in charge of your uniques metabolism.
Good luck! Sorry if I answered with more detail than you wanted.
