Okay, so no foods really have zero calories, but you can eat food that takes more energy to digest and absorb into the system than the actual energy in the food itself. This means that some foods have less calories than the calories your body uses to process it. So theoretically, you can eat these foods as part of your daily diet and not worry about counting the calories. Here’s a short list, courtesy of Train Mean Stay Lean, that gives you some ‘zero calorie’ fruits and vegetables. Feel free to do some more research on the subject or to find more similar foods!
