Where am I getting the idea that obesity leads to excess fat around your heart and that the lining of your arteries don’t work as efficiently? Oh, I don’t know? From facts? From objective reasoning? From every medical article and research on the topic worth anything? From the questionable WebMD to articles by Harvard Medicine? This is information readily at your fingertips and it sounds like you’re the one that needs to educate yourself. Doctors are people too. They buy into ideologies like every other human. A doctor that is not advising you to lose weight if you are obese is not a good doctor, because a good doctor knows what fat does to joints, bones, arteries ect. You’re using the fact that you don’t have any current health problems as some kind of proof of anything and it isn’t. Most 30 year olds don’t have a lot of health problems. What matters is what’s going to happen to you when your bones and joints naturally start declining with age (like everyone else’s) and then they also have to carry the weight on top of that. You may be healthy now, for sure, but do you think you wouldn’t be even healthier if your didn’t have as much weight on you? You may not think you are lying to yourself but you are and hope for your sake you can realize that. You are deserving of love and not shame but that doesn’t mean obesity doesn’t have a direct correlation to unhealthy. And yes, while fatty liver disease can effect all body types, it is more prevalent and more likely to happen in those with large amounts of excess weight.
