Your body is a car
You may not be an Olympic athlete but having a well-balanced diet will help improve your overall health and fitness levels. Think of your body as an engine that runs on synthetic oil. Of course the engine can take regular oil (processed foods) but it does not perform the same. It becomes slower and burns gas faster. It’s the same with our bodies. If you aren’t properly fueling your body, you can’t train hard and you always feel tired.
Make sure to fill your diet with a variety of whole foods and be sure to get enough protein, healthy fats, and vitamins. Eat clean and train dirty!
