Other alternatives to oral supplementation are protein powders as a meal supplement and/or meal replacement. Protein shakes are used as a "quick" and "convenient" meal or snack. One seeks these alternatives during the weight loss phase as well as the maintenance phase of weight loss. We have all been made aware of the studies performed by Dr. Atkins and the benefits of a high-protein diet. Why do we need protein? We need protein to make sure that we do not lose valuable body protein from our muscles and organs since they may never be able to be replaced. Why do high protein diets help facilitate the weight loss process? Protein has a thermogenic effect on the body by boosting the metabolism to a much greater extent than anything else in the food ingested; thus, burning more calories. Protein also helps rebuild lean tissues instead of breaking them down. The essential amino acids found in proteins are converted into neurotransmitters that govern mood, hunger, appetite and metabolic status. Studies that were performed showed that women on a low caloric diet who did not get sufficient protein had abnormal metabolism of serotonin, which manifested as minor psychiatric disturbances. The body uses energy to process food that one eats. More energy is required to digest and metabolize protein than is required to digest and metabolize carbohydrates and fats. Higher protein, lower carbohydrate eating plans give much better rates of weight loss with the same number of calories. It is known that persons who easily put on weight have a poor thermogenic response to dietary fat, but still tend to respond to protein. Protein helps one feel full more quickly when eating and stops one from feeling quite so hungry, both of which help one stick to their diet. Protein takes a longer time to digest than carbohydrates, making the glucose/insulin spikes a more gradual response; thus, decreasing cravings and hunger. Not everyone can obtain enough protein via their daily meals because of their lifestyle. The hectic life of the twenty-first century requires more time spent at work and on the road and makes kitchen appliances less accessible. Traditional meals eaten family style for so many has become a thing of the past. Thus, the use of protein powders has become popular as either a meal supplementation or a meal replacement. |
