I can just hear George from last week, when the Doc was dosing a caller. Doc needed the caller's weight to dose him. George goes, "300lbs?! Three hundred pounds. Sigh. Ooookay, Doc, (voice heavy) here we go".
Gees, George. It's not a beauty pageant. Get a grip. The Doc needs the callers' body weights so he can tell them how many cans of his product to drink each day! Think about it, the more the caller weighs, the more drinks Doc can hustle. I would think you would be able to see it that way, too. But no, when you repeated the caller's obese body weight, you sounded like you were about to have to push the back end of a semi-truck around a dance floor.
When caller's weights are relevant to the issue, let the Doc address it. Who needs a radio host to draw attention to their obesity? After the caller answers their weight, you don't need to repeat it. Everyone heard it, including the Doc. Compulsively repeating it is just rude. If repeating callers' weights is verbal filler, give it up. The Doc is fast, if he doesn't have to cringe while he is trying to calculate. Other verbal filler could be, "Let's give the Doc a moment to do his figuring". Those callers already know they have a problem. If they are female, they constantly are bombarded with images that clearly show their bodies do not measure up. They don't benefit from you drawing attention to their weight.
And don't forget your praised VS models are often hospitalized for starvation, or complications of bulimia, even though it gets no press. And they may be on laxatives, steroids (national female swimmers destroy their breasts with steroids) or even hard drugs. Most druggies are thin... So don't act like a lightweight is any healthier than a heavy weight until you know whether or not they are bulimic, on heroin (

My former neighbor was a hard-working, thin carpenter. But, he suffered a devastating heart attack, because he did not eat a healthy diet. His wife confided to me that he ate a lot of sweets which probably had trans fats in them (2007). Other residents on the block, including her, were his age and much fatter, but he was the only one that had a heart attack (or stroke) in the 8 years I was there.
You have said that you had a cardiac problem around the time you were 50. Were you obese or morbidly obese? Probably not. Were others obese? Yes. But you, reasonably-thin-50-year-old-you were the one who ended up in the hospital. Do you see my logic.
Of course obesity is not good. But the callers already know that. And many things are worse than obesity, like looking down on others, sounding condescending or pitying them in an embarrassingly public way. They are already embarrassed. You don't need to maximize their embarrassment. You really put that one recent woman on the spot last time, almost arguing with her because she said, "That's not my weight" instead of "That's not my ideal weight". She misspoke because she was embarrassed. Everyone could tell. And then, instead of letting her out of that part of the conversation, you just went for blood.
