Carboyhrates are basically main source for formation of glucose in human body. I check increase in blood sugar by restricting or minimising intake of carbohydrates ( food like rice, atta, potato etc.) and suplement my loss of meal by increasing intake of food with either less or no carbohydrates such as vegetables etc. A regular excercise of at least 45 minutes is a must for me. Recently within three days I could reduce my blood sugar level from 370 (FF) to 125(FF).
