I personally cannot answer your specific questions with a specific answer. I think any training to lose weight you need to check with a doctor and possibly a personal trainer.

I have no idea how much running you will have to do for a middle school game. I really do not think anyone can definitively answer that question here. I am sure it varies based on the style of play and the ability of the kids.

It sounds like you need to get yourself physically ready to work games and not worry so much about what specifics you will do as an official. The bottom line any officiating can be physically demanding on the body and you have to be prepared to handle it. Once again talk to a doctor so that they can address your personal physical challenges. It is hard to know without knowing if you have knee, back or even heart issues.
