Disadvantages of eating High-Protein Diets
Its a common idea that a high protein diet will help us grow healthy but do you know overeating proteins can be injurious to health. So your buddy tells you he’s starving and has a case of hunger breath. After your workout, you guys head to lunch. He orders a cheeseburger deluxe platter, no bun, extra cheese, no fries. He explains the carbs are totally bad for him and that he’s on a high-protein diet. Whether it’s the Atkins Diet, Zone Diet, The South Beach Diet, Meat-Mania, Proteinopia or whatever fancy name they call that high-protein diet he’s on, it’s doing more harm than good.
The calling card of high-protein diets is that your body burns fat for energy and that, in turn, will result in weight loss. Prolonged consumption of high protein sends the body into a state of ketosis. That’s top of the list of cons of high-protein diets. Ketosis occurs when the liver converts fats into fatty acids for use as energy and the by-product, ketones. Ketones increase the acidity of the blood and can be detected in the urine. In extreme cases of starvation or fasting, the body undergoes gluconeogenesis, which is the production of glucose from sources other than carbohydrates, primarily protein.
Possible kidney damage
High-protein diets place a lot of stress on the kidneys. The initial weight loss on high-protein diets is from water loss. When carb intake is restricted, the body uses muscle and liver glycogen for energy. For each gram of glycogen, two grams of water are used or “lost.” The minute you give into your carb craving, that weight will come back. The diuretic effect of eliminating carbohydrates from your diet stresses the kidneys while they remove urea, a by-product of protein synthesis, from the body. Compounding that problem, when the body is in a state of ketosis, increased levels of calcium are excreted — that can lead to kidney stones; a build-up of calcium in the urine. Think about the experiment when you put a nail in a cup of Coke: After a few days the acid in the soda starts to dissolve the nail. The same breakdown happens to your bones. Calcium (along with other minerals) is leached from bones and teeth because of the increased acidity of the body. Literally pissing away calcium is a major con of high-protein diets because that will have a negative effect on your workouts. Calcium is a necessary mineral for muscle contraction and nerve impulse. Calcium loss can also lead to stress fractures.
Increased risk of cardiovascular disease
A balanced diet consists of approximately 60% carbs, 25% protein and 15% fats. However, 30% to 50% of calories come from protein on diets like Atkins. That shift also means an increase in fat consumption: up to 50% of calories come from fat, and increased calorie consumption. For every gram of carbohydrates there are four calories compared to nine calories per gram of fat. Meats, cheese and eggs — animal and dairy products — all contain saturated fats and cholesterol, even the leaner varieties. When you think about it, how healthy does eating sausage, egg and cheese for breakfast, a cheeseburger and milkshake for lunch and (let’s say you’re trying to be healthy) a salad for dinner with chicken, egg, bacon bits, nuts, and with Ranch, Caesar or blue cheese dressing sound? Over time, consumption of this ort of diet, along with limited fiber and fruit consumption will raise LDL cholesterol levels and increase the risk of heart disease.
