Im 18 years old and im tired of being fat i weigh around 250lbs, How do I start?

I've been fat for as long as I can remember and quite frankly I'm tired of it. I want to finally do something about it so I want to start intermittentfasting, however I do not know how/where to start with this or what foods I should start to eat. If it helps I've started doing cross country. via /r/intermittentfasting https://ift.tt/3kUSqHz https://ift.tt/eA8V8J
