Green light foods are okay all the time. You have a green light to eat them (in the correct serving size). These foods are GOOD FOR YOU!
Beans and legumes
Yellow light foods are foods that you need to precede with caution. These are usually your proteins. They tend to be higher in fat and calories. Ensure proper SERVING SIZE!
Red light foods are a treat and should be eaten rarely if at all. These are foods that are high in fat, sugar, salt etc. These foods ARE BAD FOR YOU.
Juice (I know, what about 100% fruit juice, no sugar added? If you have this in the correct portion size, it's not bad for you but too many calories too easily)
Until next time! Good luck and enjoy your new color coded foods! :)
