I'm mainly looking for their successful treatment of others because that is a typical way to assess medical professionals. When a surgeon wants to perform a bypass, most people ask how successful that surgeon has been in the past.

I understand that you're saying that the doctor can't do anything if I'm so lazy that I find excuses all the time, but I don't feel like I have ever given a doctor an excuse. I feel like doctors give me excuses constantly about their success rates.

From my perspective, if they give the same advice to 100,000 people and of them they have 0 successful treatments by their own data, I'm going to assume I should find other advice

The advice is always going to be some variant of consuming fewer calories than you expend. Obviously the success rate is >0. Other than that I suspect you're just looking for reasons to argue instead of taking responsibility for your own choices.

I wish I found that a success rate is >0 to be so obvious, or else I wouldn't be asking the question.

Do you know anyone lifelong obese that has had a year or more of losing weight?
