(Tobias, 2013) Physical performance depends on multiple variables such as strength, which mainly means muscle strength and the only way to increase muscle strength is through muscle breakdown and the synthesis of the muscles being torn down. Protein is the overall number one factor that plays a role in the rebuilding of the muscle being broken down. When protein is consumed in any matter, such as supplements or through natural protein in food, the protein is used to rebuild and help structure muscle and all other parts of the body (Wolfe, 2000). “A study published in the International Journal of Sport Nutrition and Exercise Metabolism concluded that "whey protein supplementation during resistance training offers some benefit compared to resistance training alone." In addition, "males who supplemented with whey protein had a... ... middle of paper ... ...Williams, Michael F. Carey, and Alan Hayes (2006).
The Zone Diet High-protein/ low-carbohydrate diets are nothing new to Americans these days; they seem overwhelmingly to be the most popular among those people trying to lose weight. Ph.D. Dr. Barry Sears’ books on his version of the high-protein diet, the Zone Diet, are among the best selling diet books on the market. The diet seems to be yielding quick and noticeable results to those who follow Dr. Sears’ plan. Many people are desperate to lose weight and have tried numerous methods that have not produced sufficient and long lasting results. This could perhaps be the reason for the recent craze for the high-protein/ low-carbohydrate diet- it really does cause weight loss.
High Protein Diets for Weight Loss The Role of Dieting in Society Today The preoccupation of modern society with appearance is reflected in part by the preponderance of Americans who engage in dieting behaviors. Despite the nutritional and fitness literature which pervades society today, 33% of the American population continues to be overweight (Bates, 1997). The USDA recommendation for a low-fat, high-complex-carbohydrate diet over the years has seemingly not been effective, since the proportion of overweight Americans has increased. Many frustrated Americans have in turn looked beyond the high-carb, low fat diet to other less conventional measures (http.//web.usatoday.com/life/health/lhs641.htm). Dietary fads have sprouted over the years to meet this need for a novel approach to weight loss.
The digestive system is important for breaking down food and turning it into nutrients. The body uses the nutrients for energy, growth, and cell repair. The food and drinks that a person must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. Compared to the other systems in the body, the digestive system is one of the most diverse and important.

Recently, there has been more interest by the public, geared towards the Revolutionary Atkins’ diet. Although the Atkins’ diet appears to be the dream diet in the battle against the bulge, it can cause serious health problems if done incorrectly ( Dr. Atkins’ 72-80). The Atkins’ diet is a high-protein, low-carbohydrate diet, which has been attributed to the weight loss success of thousands. The Atkins’ diet is based on the belief, that by increasing protein and decreasing carbohydrates, the body is forced to burn stored fat. Many researchers, who study the success of diets rich in protein, believe that insulin is the hormone that makes people fat.
The American culture today presents a rift between many different lifestyles: to the rest of the planet, we’re known as the fattest country in the world, the creator of fast food and drive-throughs, and as a nation constantly seeking indulgence. Within the United States however, we see a growing trend in fitness and overall health consciousness (although we still have a long way to go). We celebrate the shredded bodies we see on places like Instagram and MTV, and marketing companies have taken notice. The experts tout supplements, pills, and powders as the elixir to a muscular, strong physique. Anyone who regularly lifts weights at the gym will easily notice the protein-shaker bottles, supplements, and various additives that athletes use to “get big.” With so much misinformation presented by unknowledgeable peers and paid sponsors, how can we acquire meaningful instruction on healthy living?
Firstly, fat is necessary as it is a source of energy and energy store for the body, and provides certain fatty acids that the body cannot produce. However, eating food with high fat content can eventually lead to serious health problems such as heart diseases, diabetes and high blood pressure. Protein intake is another important component of nutrition as the body can only create 10 of the 20 essential amino acids. The other 10 have to come from the food consumed. Proteins are essential for tissue repair, enzymes, hormones for metabolic processes and most importanly, antibodies that make up part of the immune system.
So when they are adjacent, an enzyme can cause them to join by catalyzing dehydration synthesis. ("Amino Acid") Moreover, essential amino acids are those that cannot be synthesized in the body and must be taken to obtain protein from rich foods that contain them. Our body breaks down protein to get the essential amino acids and form new proteins. Essential amino acid can be found in eggs, dairy, seafood, and beans. Out of the twenty amino acids in our body, nine are essential in our diet.
