The fundamental misunderstanding here is that you think "healthy" has a specific meaning. For fats, the definition changes from moment to moment. I have some examples. If a fat says a food is healthy and they seem upset about it, it may involve vegetables such as kale or zucchini. If they seem pleased about it, it may involve vegetables such as deep fried potatoes, or marinara sauce. If a fat describes a person's physique as healthy, they probably mean fat rather than toned, though the "do they seem upset about it" rule can apply here, too. If a fat describes themselves as healthy, it may mean that they haven't experienced any health problems yet, or it may mean that they haven't expanded total organ failure yet. Or, perhaps they walked around the block once last month, so they can say they regularly work out and are therefore healthy. They may have sacrificed a leg or two to Lord Beetus, but still describe themselves as healthy because they have less chronic pain today than usual. Or, they may describe themselves as healthy regardless of circumstances because they're trying to justify eating more of whatever it is they're eating that they feel guilty about.
