"Struggling to eat better? You're not alone. Eating healthy is not always easy. And science tells us that it's not entirely our fault. In a world where food (especially the unhealthy and highly processed kind) is so readily available, it can be tough to change your unhealthy eating habits. However, Why don't our bodies crave the stuff that's good for us? First of all, processed and fast foods can truly be addicting. In fact, a 2010 study published in Nature Neuroscience found that when rats were regularly fed fast food, their brain chemistry changed-and not for the better. The rats became obese and lost the ability to determine when they were hungry. At the same time, it's important to remember that creating new habits (both good and bad) takes time. It's safe to assume that you'll have a hard time sticking with your healthy diet if you go from regularly eating french fries to strictly salads in one day" claims Jessica Smith,certified wellness coach, fitness expert, and personal trainer.
