I was a video about Fat Doctor pop up on YouTube after not hearing anything of them for a long time. I didn't know they were going by 'He' now.
It is rare to encounter such an utterly unpleasant individual. They have such a nasty, smug and mean attitude about everything and everyone.
I don't like to make comments about appearance, but they have always looked tired, unwell and untidy to me. This is nothing to do with weight, I feel like their unpleasant attitude has filled them with such spite that is just radiating out of every pore. They do not look happy and they are a poor advert for their claims.
I haven't seen all of their content ( and frankly I don't want to), but I wonder if they used the persona of 'The Fat Doctor' to deal with all the stress and problems in their life, giving them an outlet for all the stress they were feeling by giving them a sense of control and power. But somewhere along the way it went to far, and Fat Doctor became their entire personality and life.
This is purely on the basis that they have mentioned a lot of stressful personal situations, and I also can't imagine someone actually managing to hold down a job that involved dealing with the public for a few years, and get married if they had such a stinky attitude the whole time.
