Eating healthy is one of the most important aspects when keeping fit. If you're looking to loose weight, don't stop eating, just eat the right food in the right ammounts. Same goes for gaining weight! To ensure you're eating the right portions of good foods, keep your body type in mind! Call your doctor and plan a good diet to follow to ensure that you can follow-up on everything you're eating and in what portions. Stay away from eating too much 'junk', and NEVER eat right after a workout!
