Protein – When protein is digested, amino acids are released. Amino acids are the building blocks the body uses to construct and repair damaged tissue, to build muscle. When you work out intensely, you damage the body, and force it to make itself stronger and able to exert more effort. Amino acids and protein also work as hormones, enzymes, and transporters of other chemicals in the body. Protein provides structure for the body. However, you don’t need excessive amounts of protein to get big muscles, or for any of the other reasons that the supplement companies try to shove down your throat.
When adequate energy is available, amino acids are used to build and repair damaged tissue, to work as hormones, enzymes, and to transport chemicals in the body. However, to the body, energy for survival is more important than growing bigger. If you don’t eat enough carbohydrate-rich foods, the liver breaks down amino acids to make glucose for fuel. The body breaks down ALL non-essential protein to ensure that it has energy for the cells. You don’t get bigger. Your body goes into a catabolic state, where it feeds on the muscle, instead of growing it.
The body CANNOT use more than 1.7 grams of protein per kilogram of bodyweight per day to make tissue. That’s a scientifically proven fact, folks. 1.7 g protein/kg bodyweight/day. The body is unable to store excess protein as protein or as amino acids. It is either used as energy or stored as fat. Protein produces more by-products than carbs, and more harmful by-products at that.
The average sedentary fatass civvies male needs about 64 g/day of protein. An 80 kg (175 lb) soldier training heavily can use up to 136 kg/day. You don’t need to intake massive quantities of protein powders and pills, and cans of tuna very 20 minutes to reach this. The average North American diet supplies more than enough protein for athletes. By choosing a sensible amount of food from the four food groups, and eating 4 – 6 small meals a day, you can easily reach 136 g of protein. Eat a healthy diet, as outlined by Canada’s Food Guide to Healthy Eating, and you WILL get enough protein. Even a vegetarian will get enough. Anyway, during an intense strength- training program, you only require an additional 28g of protein to meet your body’s needs. The majority of the protein you require is resynthesized from protein that you break down during training.
So, you see where I’m going here? Carbohydrates are actually more important to building an athlete than protein. And, being a hard-core carnivore, that breaks my ******* heart. But, science has proven it. You only need about 10 –35% (at most) of your daily energy intake from protein. If you’re very active, you don’t need to increase your intake of protein alone, you need to increase your food intake, period. You need to eat more carbs and fat, as well as protein. As long as 10% of the food you eat in each sitting (meal or snack) is protein, you’re getting enough. And, that’s easily done by simply following the Food Guide. If you eat very little throughout the day, then you need to increase the amount of protein in each sitting to the 35% mark. But, then, you’re not going to perform as well, anyway.
It’s ridiculously easy to eat enough protein for muscle growth. Foods from all 4 groups contain protein, it’s only the amount of protein in each that varies. Meat obviously has the most, with cereals having the least. Even a snack of crackers and an apple has protein in it, even though you don’t have meat or a meat-alternative in there. Throw a tiny bit of peanut butter on the crackers, and you’ve got a high-protein, high-carbohydrate, after-workout snack.
Protein Supplements – They’re not all evil. They’re not totally a waste of money (just mostly). Some protein supplements, and many meal-replacement supplements, also contain carbohydrates, vitamins and minerals and, as such, can have a place in situations where perishable food is not an option. In this situation, choose a supplement that has a greater carbohydrate content. But, they are never supposed to replace actual, you know, FOOD!
In terms of nutrient value, food is a much more economical and nutritious choice. Supplements lack the important extras such as fiber, phytochemicals and the proper balance of vitamins and minerals that foods have. Your body was designed to extract the nutrients it needs from food, not from chemically created supplements. Too, many of these supplements provide low quality protein, too much of a single amino acid or too few essential amino acids, resulting in waste and strain on the digestive system. Ingesting protein as a single amino acid can inhibit the absorption of other essential ones as they compete for the same absorption sites in the digestive tract.
If you want extra protein, rather than spending big bucks on protein or amino acid powders, try good old skim milk powder – it’s cheaper and contains whey as well as other proteins. Mix it into milk, puddings, soups, sauces, even meatloaf. Believe it or not, the best supplement out there is probably Carnation Instant Breakfast, with some fruit, say a banana.
