@dar858 I agree with joining MyFitnessPal and monitoring your food intake. You will really start getting an idea of conscious eating. What to avoid, what to limit, what to add more of.
Why don't you YouTube workout videos on YouTube... there are so many options using bodyweight exercises. Depending on your level, you can opt for shorter videos, low impact workouts until you build your endurance.
Walking is great. I would get a pedometer and try to make step goals to hit each day
If you like Burgers and Tacos... you can totally continute to eat those things.
I would convince your dad to incorporate healthy substitutes to the foods that you already love.
Examples:
-Use 93/7 ground beef for tacos and burgers vs. 80/20
- Use whole wheat, low carb tortillas
- Use whole wheat hamburger buns
- Oven bake your fries instead of frying
- Eating Baked Lays
- Adding plenty of lettuce and tomatoes to your burgers and tacos
If you need help, just ask. I've been doing MyFitnessPal and making health substitutes for a while.

Lose Weight Eat Pizza is a great FB group as well.
