Many dance students want to know about natural muscle building, and build those muscles up. Perhaps you want to lose weight and keep it down, or simply build healthy muscle for your ballet training. Whatever your reason, understanding how protein functions as the body's prime fuel, and aids in maintaining a healthy weight, will influence your choice of a protein supplement. If you are on a fat burning diet, please bear in mind that most protein supplements are not meal replacements, but can be used to help you restore muscle that you break down with exercise.
So why think about adding protein if you eat healthy meals? At one end of the spectrum you can get the drive-through hamburger, reduced in calories by having a lettuce wrap instead of a bun. However, you still have the load of saturated fat, with questionable quality beef. Beef fed with grains, which give you too much omega 6 oils, and not enough omega 3 oils. The abundance of omega 6 fatty acids promotes inflammation in the body. Inflammation is natural, but should always be a temporary healing process in the body. Chronic inflammation leads to the "killer diseases": cancer, Diabetes, arterial disease, heart disease, everything a natural diet will help you avoid.
By natural - the other end of the spectrum - I mean organically produced foods, vegetables and fruits and salads uncontaminated by cancer-causing pesticides and herbicides. And when it comes to meats - why shouldn't those animals eat organically and naturally too? Fortunately, many herds do.
You can then benefit by getting protein powder made from healthy whey - milk from not miserable cows, spared the grains, growth hormones and antibiotics that most bovines are fed. Cows that get sunshine and get to wander around munching on juicy green grass. You get the benefit of higher anti-inflammatory omega 3 fats in the resulting foods. And the key here is that when your body is fed enough protein, it is triggered to allow the burning of fat for energy.
Years ago I spent a weekend in the country at a fellow performer's family farm. At the end of every hearty home-grown meal, all the leftovers were wiped into a huge bowl to be taken out to the pigs. I commented on how well their pigs were fed. My friend's grandmother quipped "Well, we're going to eat them!".
That was the first time I ever thought about what the animals I ate, ate. I was very ignorant of the "progress" in the food industry. I recommend that you eat well-fed protein products if you are trying to improve your natural muscle building.
