It took me a little over a year to hit the 100 lb. mark. Stayed near induction level carbs for the most part, between 15 and 30 g. per day. Started exercising after about 4 months, gradually stepped up the exercise in both frequency and intensity. I am a big proponent of exercise. Be patient, you'll get there in time. You will have bumps and periods of slow loss; try think of this as a way of life and not a finite race to see how fast you can lose all your weight.
