40 Lbs since May

I am 71 and have always been overweight. Now, I am also Type 2 Diabetes. So having you explain that insulin is a hormone that causes fat storage, I have cut out the sugar and all other carbs. Averaging a loss of about 8 lbs a month. Eating well with IF of 18/6. Can't wait to get blood work done to see what my A1C will be in December after 6 months of no carbs.
