If you're flat broke but eating out everyday, you're doing it wrong.

I've no idea what will work for you but here's what worked for me: Limit carbs to; during rides, after rides and in preparation for any racing you may do. Cut out sugars, boost vegetables and meat consumption.

I used to make ice cream and desserts for a living so I know all about a wicked sweet tooth. It gets easier to adapt the longer you abstain or reduce your intake. I still have the occasion bowl of ice cream/cereal but it's not a routine thing anymore.

Also understand that being healthier isn't a one-shot deal; it's a lifestyle change with minor deviations, and real change is slow and difficult.
