I have been doing it this past year. I went online and found out my daily cal. needs for someone my age and goal size then on my cal. up day I go up to that point in cals. with a disregard for carbs. So it was still a weight loss day just not a super low carb day. By banking cals I was able to have a really high cal low carb day without a stall as well. I am a over 50 short small boned female so I have to count both to lose
