Wouldn't surprise me if "your patient" there...had fluid balance problems...causing them to gain weight even while eating a 400-calorie-a-day diet. Either that, or they were cheating.

Oh, she was cheating. We had more than 150 patients then, and she was the ONLY one who didn't lose any weight at all. Some just lost a few ounces some weeks - you know how the body is when you put it through extreme diets - but everyone except her lost SOMETHING.
