I don't think that you can effectively delegate all decisions about your health to someone else.
There are no effective noninvasive expert-based weight loss regiments. At the same time there are people who lose weight through being motivated to lose weight and working on the goal.
A product such as 23andMe can give a patient useful information about their health without there being a expert doctor who tries to translate. Current laws prevent a customer to buy data interpretation directly from 23andMe.

I think the room agreed that it would be good for medicine to be a bit less expert-based. We had a president from the medical association explain us that doctors likely aren't qualified to give good answers when you come to them with good data.

I would support people getting information about their health from organizations like 23andMe. But I don't expect 23andMe to do all research on their own -- at some moment they are going to rely on some peer-reviewed study. There should be a system where the studies ar...
John Ioannidis has written a very insightful and entertaining article about the current state of the movement which calls itself "Evidence-Based Medicine". The paper is available ahead of print at http://www.jclinepi.com/article/S0895-4356(16)00147-5/pdf.
As far as I can tell there is currently no paywall, that may change later, send me an e-mail if you are unable to access it.
