The real reason being overweight is bad for your health:

29. There is a lot of info out there

It is shameful how many people are suffering from a host of maladies, take a handful of expensive medication for strange unexplained symptoms, and doctors, in their infinite wisdom, are not able to look at underlying causes and see it is a systemic problem. High cholesterol is being treated inappropriately with statins to make pharma companies billions, when high cholesterol and heart problems are hallmarks of hypothyroidism. Infertility--my neighbor (who just looking at her you know she's hypothyroid and so is her brother) spent $30k in order to conceive. Now maybe there are other reasons, but treating a thyroid is incredibly inexpensive and easy. Get up to a high enough dose where the symptoms subside. Maybe that's why they don't do it.

And now, synthroid, the synthetic hormone which only treats half of the problem and is completely ineffective and often makes you worse. But it is the number three prescribed medicine and making billions and billions. I hope you are able to find a doctor who will prescribe the dessicated thyroid in sufficient doses to cure symptoms, not to the test. That is how they were successfully treating thyroid problems before the turn of the century up until the 70s. The pictures on the internet are astounding. There are also a lot of resources out there like "Stop the Thyroid Madness" and the Broda Barnes foundation. I hope you find good treatment because it could help you feel like you got your life back.

Like your brother, so many people have been super shamed as overeating and lazy. I do know people who have an awful diet and don't exercise a bit. Some are fat and some are skinny. But I have never known a person who works so hard at the gym, waking up before the crack of dawn and basically starving themselves on strict diets only to lose a pound here an there as an obese person trying to lose weight. The skinny fit people I know work hard, but more like a maintenance mode. They people bust their ass. They have so much effort and discipline and all they get is sneers from their family and their doctors. It's very sad.
