Anyone do MMA?

I really want to get into MMA and was wondering what kind of build is the best for MMA or does it matter? I know MMA takes a lot of time and training. I am doing as much research on it now but I am not starting to train just yet. I am slowly progressing in losing weight and eating healthy. Would love if some people who do MMA would give tips or information at a personal view instead of reading a bunch of websites online.
