How can you lose weight and what type of food you should eat if your mom doesn't cook and if you don't cook well?

So I'm been having poop problems. I want to be healthy. I'm 196 lbs and 5'9. Give me examples on what type of food should I eat if my mom doesn't cook and I don't know how to cook well. And what I can do to workout? my mom and I don't have a car. We are always home.
