Funny that you should mention health care, because those in the health care professions know absolutely nothing about weight loss. I recently went into the Doc because of a 20 lb weight gain that happened over a six-week period. A tingling in my right side and numbness in my right foot accompanied it, not to mention other unmentionable symptoms. The Doc’s answer? Eat less and exercise. I’m not a big eater, and I exercise regularly. His standard answer might have worked, except I had two bulging discs that soon blew. Once I was in extreme pain, they figured it out and took me to surgery. Now I’m fine, but at 40 those twenty pounds aren’t going to be easy to lose. Quack, Quack!
...and many other things. I could tell you the same story about trying to get treatment for an arthritic ankle. Quack! Quack!
But it's the best we've got. It's up to the individual to seek out the best he can find and make decisions about the (likely) efficacy of the (recommended) treatment.
