Body hoarding food?

I am 15 mths post-op, down to size 2/4 (from 22/24) and am 5'-7".  I have been at this weight (140's) for the past 4 months.  I do about 8-9 miles per DAY.  I am not able to eat alot, and am concerned that my body is hoarding the food that I am eating as it is not getting enough calories.  I drink 150+ounces of non-cal, non-sgr fluid per day, my blood work levels are SUPER and I feel great (most of the time.)  I honestly only intake about 700 calories on a typical day...and I know I put out at least 1100 calories per day during my work-out.  Anyone else have trouble eating enough food while being so active?  I can't eat much more then I do.  I believe that I am not loosing any more weight because my body is lacking the caloric intake needed to match your output?  What do you do to get that weight to start coming off again? Thanks, Laurie

Try changing your work out and changing the food you eat not more food just different food choices
