Eating Right vs. Working Out?

What is more important eating right or working out? In my experience it has been eating right. You could work out all day burn a ton of calories and then go gain it back by eating a Big Mac, fries, and drink. Yes you'll gain muscle and get in better shape but in the end your not helping yourself be healthier. I started out just eating right and lost 17 lbs. fast. It's really important what you put in your body. I try to only eat and drink the best things for my body. I know whatever I put into y body has an effect on me for good or bad. I eat a chicken salad and I feel great afterwards. But when I eat a cheeseburger I always feel awful afterwards. So if you have to pick between making a healthy meal or working out. Eat something healthy
