Hi and welcome. That HBa1C reading isn't too bad. Set yourself a daily limit of carbs; perhaps around 150gm/day and see how you go. Carbs are the main source of weight gain and the aim is to move the body towards ketosis (fat-burning) to remove some of the excess fat. For breakfast think eggs and bacon or similar - no cereals or toast. For lunch and dinner just keep the obvious carbs down such as bread, potatoes, rice etc. Proteins and fats are fine. Try to train yourself away from between meal snacks. If you do snack think berries, nuts, cheese, bacon bits and so on. Avoid tropical fruit.
