I weighed over 300lbs at the first of the year. I started watching my carbs ONLY and am now at 237. I haven't counted a calorie once in that time. A blood sugar meter is a must if you are going to do this. Can't fool a meter. My goals are 100 fasting, 140 one hour after a meal and 120 two hours after a meal. I usually beat this pretty easily. I believe you should use a meter at first even if you aren't diabetic because it will show you how your body reacts to food.
