nudges

Can we agree that whatever of the multifactorial causes of obesity you emphasize, obesity results in other health-related problems? Can we also agree that many of those multifactorial causes are present in childhood? Then doesn’t screening for obesity and early intervention make sense; that an ounce of prevention is worth a pound of cure?
Faced with a life-changing decision and a great deal of uncertainty, do patients prefer to decide for themselves after being given all the facts? Or do they prefer a nudge in “the right direction” by their physician?
