Summarize this article in one sentence.
Contrary to what some might like to believe, there's a lot more to building muscle than pumping iron. You'll need to make sure you're getting the right kind of nutrients to encourage muscle growth as well. Many find it helpful to plan out their meals on a weekly basis. You should focus on natural proteins (like red meat), green vegetables and fruits.   If you have any excess weight on you, cutting carbs will help you lose weight and better define your muscles. Try to eat at the same times every day. This will help you digest foods better. Eating meat is not necessary for good muscle growth, so long as you balance it out with protein-rich grains and legumes. There is nothing so detrimental to one's health progress as empty calories. This includes fast food and especially soft drinks. If you have any issues with weight, you'll find your progress will get a lot faster without these. Try replacing them with water; if you need something sweet, fruit juice should usually do the trick. You should be drinking at least three liters of water a day. Not only will this give you added energy; it'll keep your muscles from tiring out as easily. Particularly if you're working out a lot, it's very important to make sure you're constantly supplying your body with new water. Dietary supplements can be very helpful, especially if you think your diet might be missing a few key ingredients. Organic, whole foods-based multivitamins are recommended over their synthetic counterparts; they may be more expensive, but they'll leave you with more energy in the long run. It should be a granted that you should stay away from artificial muscle enhancers like steroids. All of the same benefits can be gained from pure hard work, and the long-term consequences of abusing enhancers can be life-ruining.

Summary:
Make a meal plan. Cut out empty calories. Drink lots of water. Take a whole foods multivitamin.
