Better yet, follow the pre-op diet. My mom got gastric bypass and before she was cleared for the procedure she was restricted to an 800 calorie diet. Surprise, surprise, she lost weight. I asked why she couldn't have just increased it to 1200 and keep losing instead of surgery. Her response: muh life was in danger.  Now she complains about malabsorption and not being able to pills correctly because they don't have time to dissolve. She continues to reeeee because her doctors never told her it was a possibility. Conversations with her are always about her health problems, yet she continues to eat junk.  Ugh... I could go on, but it makes me depressed and angry because I get to watch her slowly kill herself.
