Firstly there is no such thing as a pure protein diet. If you eat all kinds of food, you eat fat, fat-soluble vitamins and minerals.
While protein is essential for good health, it is not the only ingredient needed for healthy metabolism. Current high protein diets also prescribe low carbohydrate intake. If you can not tolerate carbohydrates due to hypo- or hyperglycemia after eating a high carb meal, low carb diets can be good for you
High Protein and Weight Loss
However, consuming pure protein not only impossible, but such a radical diet may not deliver all the ingredients your body needs for a healthy metabolism.
According to Dr. Michael R. Eades, author of protien Power, “The liver requires energy to convert protein into glucose. The energy comes from fat. As the liver breaks down fat to release its energy to power gluconeogenesis, the conversion of protein to sugar, it produces ketones as a byproduct. and what a product they are. ketones are initially water soluble (which means that they dissolve in the blood) fat as a source of energy for many tissues, including muscle, brain and heart. in fact, ketones act as a stand in for sugar in the brain. “As a result, dieters on high protein / low carbohydrate diets experience rapid weight loss.
Real Protein Needs
According to The American Journal of Public Health, published in 1943, the amount of protein in the diet, (when other nutrients were also given) did not affect the health or fitness of the study participants. However, the study found, a diet high in protein (not pure protein) increases the absorption of calcium and essential B vitamins such as niacin and riboflavin. They also cited studies of Eskimo’s traditional diets high in protein and fat, find Eskimos enjoyed superior bone and teeth health. But Eskimos also ate raw organs, providing them with vitamins and minerals other folks get from fruits and vegetables. This is not part of the current high protein trend.
Predators vs. omnivorous
When you think of predators, you probably think meat eater. But even big cats, one of Earth’s most carnivorous species, have metabolisms designed for high protein. Nevertheless, they do not eat pure protein. Consuming whole animal means big cats also ingest the contents of their herbivorous prey belly getting their vegetables. For example, a rabbit about 1/3 lean protein, 1/3 legs and 1/3 vegetables -. A balanced diet carnivorous
Rats, at least, has shown the ability to customize their metabolisms to digest a very high protein diet. According to the Journal of Nutrition, triggering change in diet gene expression of specialty enzymes to break down proteins. In a study between the high protein diet (P50) and the control (P14) showed P50 rats increased enzyme activity. “Corresponding activities were alanine aminotransferase, arginase and serine dehydratase significantly higher in liver from P50 rats compared with P14 rats.”
While too little protein will result in the consumption of the body’s own tissues, much remains a subject of debate. According to the Journal of Nutrition’s “Metabolic Effects of a high protein diet,” excessive protein intake can lead to metabolic acidosis. This condition has been linked to muscle wasting, poor functioning thyroid and insulin resistance. The magazine reports, “An association between high protein intake, renal acid and calcium in the urine have been reported.” This means a chronically acidic state can lead to calcium depletion and bone loss.
Fortunately a cure for acidosis is fresh fruits and vegetables. Remember, while we were not made to live on pure carbohydrates, we can not consist of pure protein, either. Humans evolved as omnivores, not carnivores-so forget about a pure protein diet. Limit your carb intake, and eat lots of organic fruits and vegetables.
