She should shut up unless she examines him. He’s completely right on that.

There is currently a debate in medicine in whether weight loss, simply on its own, is actually a good thing. There’s some significant morbidity associated with increased weight loss, even voluntary weight loss—

A controversy still exists regarding the role of intentional weight loss for prognosis in nondiabetic healthy subjects, as well as in patients with type 2 diabetes, when weight loss is often a contradiction to the weight increase followed by use of some anti-diabetic drugs. Without evidence from trials, we will never be able to make justified clinical decisions on how and when weight loss should be recommended to risk patients and which methods should be preferred—lifestyle, drugs, or surgical intervention.

Observational studies only represent one first step and are not fully reliable, since rest confounding may sometimes bias the outcome. For example, the background drug medication given to patients losing weight may either increase or decrease the likelihood of achieving weight loss, but at the same time reduce risk of morbidity and mortality. One well-known example of this is the use of β-receptor blockers for secondary prevention after myocardial infarction (41). Even if a weight increase is likely to occur after the use of these drugs, thus providing harder conditions for any weight loss, the cardiovascular risk is decreased and that is what matters the most.
