It has often been said that proteins are the building blocks of muscles - and while there are a number of other factors involved, to a large extent this is true. No matter how well-structured your workouts are, without proper nutrition your muscles just won't grow and may even get smaller each week. Fortunately, today you have a lot more nutritional information readily available and much more is known about which proteins are best at different times of day.
A Fitness Fairy Tale Update...
Decades ago, little Miss Muffet sat on her tuffet eating her curds and whey, when along came a spider who sat down beside her and scared little Miss Muffet away. These days her granddaughter Ms. Fit Muffet works out regularly and gets her proteins from eggs at breakfast, tuna or salmon at lunch, whey protein isolate in her pre- and post-workout shakes, chicken or lean beef at dinner and cottage cheese an hour or so before bedtime... Spiders everywhere are very, very afraid.
The Biological Value (BV) Of Proteins...
There are 7 different sources of protein listed above and all of them are derived from animals. Animal proteins have a higher Biological Value (BV) than plant-based protein sources such as soy or beans. Simply put, this means a greater percentage of the protein you ingest is assimilated and used by the body. As such, you need to eat a lesser amount of food to supply your body with sufficient protein.
Years ago bodybuilders did most of their 'bulking up' during the off-season and went on what many thought of as a 'see food' diet - if they saw food, they ate it. So while they did get more than enough nutritional intake, they also put on 30 - 50 pounds of unnecessary bodyfat, and lost some of their new muscle as they lost weight to get back in shape for the next competitive season.
