Support for weight lost

Options
My current weight is 265 and my goal weight is 200 or hopefully less height is 6'2. It hard for me to lose weight when theres constantly fast food places around and so many things to eat. I'm trying something new today I committing to 50 days of just eating oatmeal and drinking water. Done great so far added trail mix in my oatmeal to give flavor but I got a hard road to go and would like some support.
