I think anyone addicted to the dopamine rush of food to the point they are an unhealthy weight has a mental issue, same as someone addicted to tobacco, alcohol, or any drug where overuse is unhealthy. It’s incredibly common, it’s just that obesity seems to be the most outwardly visible of those addictions and therefore gets shamed more. I don’t think shaming people into quitting an addiction is an effective strategy, but I also don’t believe affirming their choices with misinformation is favorable either. I think promoting awareness and giving compassionate support are the only real effective strategies, and while I think that’s commonly understood and used by most caring people, that doesn’t seem to be a viewpoint that gets attention on the Internet.
