The effect of physicians’ body weight on patient attitudes: implications for physician selection, trust and adherence to medical advice
Respondents reported more mistrust of physicians who are overweight or obese, were less inclined to follow their medical advice, and were more likely to change providers if the physician was perceived to be overweight or obese, compared to normal-weight physicians who elicited significantly more favorable reactions. These weight biases remained present regardless of participants’ own body weight.
I suppose it makes sense. Why follow their advice if they are unable to achieve something in their own bodies.
How does this apply to other areas like fitness or diet gurus? I think this is where it gets more complex. I think a diet guru who is promoting a certain approach as leading to health or leanness should really be healthy and lean. However in terms of fitness, the 6-pack is not always a sign that they know what they are doing. Favourable genetics and chemical assistance can often deliver a decent physique despite the particular approach to training. Looking good doesn't mean that you know what you are talking about.....but if you know what you are talking about you should at least look decent.
