Losing weight will help (reduction in visceral fat), as will exercise, especially resistance training, as muscles use the glucose for energy. The absolute imperative, however is to include a change in your lifestyle diet . Cut the carbs ( incl rice, pasta, bread, potatoes), cut processed food, sensible protein with each of three meals and lots of good fat (avocado, extra virgin olive oil, seeds, nuts, eggs, cheese etc).
The three in combination provide a much better chance of your HbA1C and Lipid panel demonstrably improving in 3-4 months.
