It seems there are two schools of behavior patients follow after gastric bypass surgery:

The first are the patients who realize WLS is a second chance to make right their nutritional wellness and they exchange the eating habits and poor food choices that made them obese for a smarter way of eating. These patients become champions of healthy ingredients and wholesome eating making conscious choices for how they fuel their bodies. They are non-stop learners in constant quest for information to aid in their health and wellness. They are actively engaged in their own nutrition to improve their health and make strong their bodies against disease. These patients have tremendous success in long-term weight maintenance following massive weight loss.

The second are the patients who rely solely on the restrictive and malabsorptive nature of the gastric bypass to lose weight. They half-heartedly follow the program during the phase of rapid weight loss and little by little the old habits that made them obese sneak back into their daily living. You
