I am preparing pre op for the gastric bypass surgery.I found MFP during my research and planning of my pre surgery weight loss requirement.I am required to loose 15lbs which is an attainable goal for me.My main concern is that I am not eating enough calories.Since I have begun to plan my daily meals and log them,I find it almost impossible to meet my caloric recommended intake.I should be consuming 1,760 but barely get over 1000 calories in.Now that I am accountable for what I consume and I can actually keep track of it, I find that I am not requiring as much food. I am afraid this will hinder weight loss. This is mind boggling to me.
