Not just that - the fear of being told their health issues are due to their weight (regardless of whether that's true) and the consequent feelings of shame can discourage many people from seeking medical help of any sort, often until it's too late. But it would be just as irresponsible for a medical professional to tell a patient their obesity is healthy as it is to immediately attribute whatever medical complaint they might have to excess weight (which, from what I've heard, still happens a lot).
