Most problems associated with being overweight simply have to do with poor diet. Let's suppose that there's a person whose diet is rich in fruits, vegetables, whole grains, unsaturated fats and lean proteins. He gets all his vitamins, avoids trans fats and refined sugars, and eats a very healthy proportion of different sorts of foods. However, lets suppose that he just eats lots of these foods. As far as I know, things like high cholesterol, hypertension, cardiac disease, etc. only happen because of poor diet, and those who're overweight tend to have a poor diet, so the two correlate. However, is there anything inherently wrong with just being overweight if your diet is healthy?
