Focusing on obesity is wrong because obesity is only one symptom of what is often — but not always — a problematic lifestyle – What is important is to be fit and healthy, to eat nutritious foods and get regular exercise. Focusing solely on weight as a factor is silly because it does not solve the underlying problems. Not that a lot of people shouldn’t be losing weight, but it is more important for them to eat nutritiously and attempt physical activity, and any net weight change is just a bonus.
