HELLO, THANX FOR USING HCM. DEAR I WOULD LIKE TO KNOW YOUR HEIGHT AND WEIGHT, WITH THAT WE CAN JUDGE WHETHER YOUR OVERWEIGHT OR OBESE AND THEN WE CAN PLAN DIET /EXERCISE FOR YOU. BUT BEING A TYPE 1 ON INSULIN THERAPY IT IS MUST FOR YOU TO TAKE SMALL MEALS EVERY 3 HOURS. SPECIALLY WHEN YOUR PLANNING FOR EXERCISE, ITS MUST TO TAKE 15 - 30 GMS OF CARBOHYDRATES PRIOR TO EXERCISE IN ORDER TO AVOID HYPOS AFTER EXERCISE, LIKE A TWO SLICE SANDWICH, FRUIT WITH CUP OF MILK,CRACKERS ( 4-5) WITH CUP OF MILK. YOU CAN REDUCE YOUR INTENSITY OF PHYSICAL ACTIVITY AND DO IT 2 TIMES RATHER THAN ONE TIME AT STRETCH. IF YOU TAKE HEALTHY MEALS WITH EXERCISE CHANCES OF PUTTING ON WEIGHT BECOMES VERY LESS. MOST IMPORTANTLY NEVER CHANGE THE INSULIN DOSE ACCORDING TO YOUR WISH.IT HAS TO DONE WITH DOCTORS SUPERVISION.
