One misconception is that carbs are needed to stop us being hungry. Wrong. Carbs make us hungry. Protein and fats keep us full, even on virtually zero carb. As you lower the carbs so you need to increase fats and/or protein. Preferably fats. This maintains energy levels and prevents hunger.
Your last HbA1c could have been a blip. It happens. Reducing your carbs and iincreasing fats accordingly should bring your levels down again, even lower, and hopefully to non-diabetic levels. However, you really do need a home meter and a detailed food diary to help you. I urge you to buy one today, no waiting or putting it off. When you get one we can help you use it to your best advantage.
As for exercise, to my mind you are doing a lot without adding more that you aren't keen on. Dancing and walking dogs are excellent. I can't say I have done any extra exercise. Mine is restricted to dog walking, ghousework, and fair weather gardening but not in winter! I lost 4 and a half stones in about 10 months following diagnosis in January 2014 and reduced my blood sugar levels. This was all down to low carb and no additional exercise. I have since reduced my BS levels even more and maintained my BMI at 22.
