Are hamburger buns bad for you? I can eat two a day depending on how many sandwiches I eat, but usually one.?

I am on a meal plan and find it's easy to get starches from meat sandwiches, I need two starches and 3 oz of meat and I add a tsp. of miracle whip because I also need a fat. Also I recently bought wheat buns as a healthier substitute. I am worried about weight gain.
