Well I DO trust my doctor, but I wouldn't trust just ANY doctor; happen to have found one I have great confidence in. And she doesn't even weigh me.
And in my case my previous doctor didn't even KNOW specifically what I was doing... he just saw the results in my weight loss and bloodwork -- was so excited he put a voice mail on my phone on Saturday saying ALL my results were "perfect" and "Whatever you are doing, keep doing it."
Unfortunately I didn't keep doing it and am now paying the price... but I am doing it again!!!
But I think it depends on what we are doing... in my case it is 99% "eat healthful foods and exercise" --- which I KNOW is right! I would class my supplement as the "other 1%" which helps me do the 99%.
Also I have found in the past that no matter WHAT I eat or do to lose weight, there are always people who step up to tell me I am doing it wrong or to recommend another "plan" etc. But it is hard for them to "argue" when they see the results.
And right now I am THRILLED with what I see and feel happening in my body... and I AM glad my doctor agrees!
Great idea too to check with a nutritionist... but I think that the vast majority of people do neither... just go off on their own "diet plan" or the many fad diets that are always around, or a magic pill.
