Summary: MyFitnessPal is probably the most common fitness app or food tracker on the market but registered dietitian, Melanie Douglass has a warning when it comes to tracking your food. People make two common mistakes with fitness apps. One is that they overestimate how active they are and they don't track or measure the correct foods. It is important to pick a food tracker that gets into calorie and nutrition information from the USDA, not user generated.
