I just went to see my nutritionist for my type 2. I am trying to lose 100lbs over the next year. My doctor recommended that I reduce my fast acting insulin by 10 units when commuting. My commute distance is 13 miles one way. Carrying a soda, gels, and snacks for lows. She also recommends that I reduce my fast acting insulin by 5 units when I consume less carbs. This is my first week on this. I use Novolin N and R insulin. R is the fast acting insulin. I'm taking 2000 MG of metformin a day. I can also have a protein snack.
