I'm wanting to create a mobile app for my local gym that is tied to what you eat and what the punishment would be for eating that food.
For example; if a cheeseburger requires 100 pushups to make up for the cheeseburger, then I want the app to calculate the number of pushups required for a certain meal.
I can provide the number of calories a specific workout requires. For example, 1 pushup burns 5 calories, so a cheeseburger with 500 calories would equal 100 pushups.
What I don't know how do do is pull data about food information such as apps like this: https://itunes.apple.com/us/app/fast-food-calories/id402447013?mt=8
I would need to get access to all of the fast food places and would need the option to manually put in certain types of food manually.
