I am creating a fitness app for the iPhone. The target audience is NORMAL people who try to work out a couple times a week. The target is not hardcore gym buffs; I'm aiming for people who go to the gym from time to time to stay healthy and feel good. They sometimes make fitness goals, but don't always have the time to achieve them.
I would like a row of buttons which display six different food groups. Each button should be 44x44. Here is what I consider to be the food groups:
Icon 1: Meat, chicken, eggs
Icon 2: Fruits, vegetables
Icon 3: Grain (bread, wheat, rice)
Icon 4: Milk, cheese, yogurt
Icon 5: Sugary foods (donuts, cookies, cakes)
Icon 6: Fatty foods (potato chips, pizza)
Do not put any text on the buttons. Don't make them way too complex, since they are so small and will be displayed on a tiny device.
