You can get a lot of flaky diet fads from women's magazines, too.

I don't know if its just me who's noticed this, but if one pans out and takes an overview of the main diet fads over the past 30 years, one will notice that the main focus of a diet changes every 10 years or so.

Recall in the 90's when everything was "low-fat". Starting somewhere in the 2000's the health industry switched it over to "low-carbs".

In the 80's, if one wanted to build muscle they were told to eat as many carbs as possible. Nowadays one is supposed to eat as much protein as possible.

This is just diet information. Methods of exercise change too. In fact, they sort of cycle in a way.

Ever feel like the health industry is trying to pull one over on you?

In general I'd support that we have medical professionals to make these decisions for us. I would prefer to have someone I trust, is well educated on the subject, and keeps up with the literature who can point me in the right direction. One result of the specialization in our society and our inability to stay on top of every subject that affects our lives, is that no one can make a truly informed claim on every life decision.

Sadly, many health practitioners are less motivated by science and more motivated by process. They stop educating themselves after they have finished their residency equivalent. Once they are in charge of medical decisions they are bombarded with marketing, which has the goal of selling products, not necessarily with helping anyone.

At this point, I don't know who to trust for medical advice.
