I spent many, many thousands of dollars on everything I needed -- and that's not including the tens of thousands my insurance covered. The vast, vast majority of the US population would not be able to afford this. I would very much support subsidizing medical care to a greater extent, but it's not just medical care. The diet (New Direction VLCD) I was on cost me $22 for a box of 7 shakes, of which I would have 3 per day -- $282/mo just for that. That alone puts it out of reach for many people, sadly.
Aside from just the economic side of it, it is exceptionally difficult to lose weight. It drove me to tears and severely impacted my mental state (despite also being treated for my mental illnesses) and that's even despite being very motivated to succeed. I don't look down on anyone looking for an easier route, whatever that may be; if I saw one, I would've taken it myself.
