Eat healthy food a lot. Your parents will be more likely to give you fast food, if you ate more healthy meals in the short-term. Then your parents will be more likely to think that you can have fast food and that your health will not collapse into disrepair and neglect.

Give preference to whole grains such as whole-wheat bread, corn tortillas, brown rice, air-popped popcorn, and oatmeal. Look at menus. Check out the menu before going to the restaurant and look up the nutritional facts. Most fast food places have begun to roll out healthier menus, and you may be able to convince your parents to buy you some of the healthier options, like the lower calorie Fresca menu at Taco Bell or some healthier sides at McDonald’s.

Know that as long as you aren’t eating more calories than you need every day, you won’t gain weight, even if you only eat fast food. [4] X Research source

Keep an eye on deals. Often, fast food chains will offer deals that drop the prices of meals substantially. Restaurants often advertise on the radio or TV, so watch for two-for-one deals, coupons, or limited-time-offers that might make a meal more affordable. [5] X Research source
