Julia Belluz in Vox:
Diet books are a multimillion-dollar industry, and it's no surprise, since millions of people struggle with their weight and long for answers about what they can do to slim down. Books can provide valuable tips on healthful patterns of eating. Some are more outlandish than others. But the problem with all of them is what they promise when it comes to weight loss.
No doctor has ever uncovered the solution to weight loss. If someone had found the fix for this immensely vexing and complex problem, we wouldn't be facing an obesity crisis.
But unfortunately, more and more respected doctors, despite their good intentions, are complicit with the publishing industry in confusing science and obscuring hard truths about obesity to sell diet books. It's one thing when actress Gwyneth Paltrow tells people to avoid “nightshade vegetables” on an elimination diet, and quite another when a highly trained and credentialed physician sells a weight loss lie.
