Once you have your basal rates, insulin sensitivity and insulin/carb ratio sorted you can really eat almost anything as long as you pre bolus accordingly. For getting these as accurate as possible seek advice from your DN practitioner. I did basal tests first and adjusted accordingly, once happy, I sorted my insulin sensitivity by ensuring I had no insulin on board and if at a safe level ie about 8mmol injected a small amount of insulin ie .25 units an monitored carefully to see how much my bloods dropped. When they leveled out I multiplied the drop by 4 to obtain my ISF. I then tackled my carb ratios by eating small lowish fat meals. Eg I had the same breakfast, same lunch and same dinner at the Same Times monitored the results and made very small adjustments to my ratios if need be. It is quite a painstaking process but we'll worth it. But please... Please seek advice from your health care provider before making any changes... Good luck and all the best
