Worth a read, and worth a watch. This mimics a bit of my experience, my family's experiences, and brings up some (deeper) questions. As someone who's had gastric bypass in 2004, I'm always intrigued at any new science that's discovered about the gut - brain connections.
"Nearly 200,000 Americans have bariatric surgery each year. Yet far more — an estimated 24 million — are heavy enough to qualify for the operation, and many of them are struggling with whether to have such a radical treatment, the only one that leads to profound and lasting weight loss for virtually everyone who has it. Most people believe that the operation simply forces people to eat less by making their stomachs smaller, but scientists have discovered that it actually causes profound changes in patients’ physiology, altering the activity of thousands of genes in the human body as well as the complex hormonal signaling from the gut to the brain."
