That matches the low protein diet given to the test subjects. The study subjects were tested for their blood urea nitrogen BUN , urine concentration, and other lab values every two weeks during the study. The BUN test is one performed routinely as an indicator of kidney function. It measures the breakdown products of protein that are cleared by the kidneys. Alarmingly, the BUN reached the abnormal range when the student athletes ate the high protein diet.
Their urine was also more concentrated, which is a sign of dehydration. Their values returned to normal when they went back to their usual diet. They didn't feel thirstier when on the high protein diet, and so they might not have been drinking enough water to meet the needs of their kidneys to dispose of the waste products of digesting protein.
The American College of Sports Medicine's position on nutrition and athletic performance recommends staying well-hydrated before, during, and after exercise to balance fluid losses. Sports drinks with carbohydrates and electrolytes can decrease the risk of dehydration and hyponatremia. Get nutrition tips and advice to make healthy eating easier.

You're gaining weight. If you've bulked up on the protein in your diet without cutting calories in other areas, you may find yourself gaining weight. In a study, researchers found that people assigned a high-protein diet gained the same amount of fat as people assigned to a low-protein, high-fat diet , when both groups overate. The high-protein eaters gained more lean body mass, like muscle, as well, TIME reported. You have kidney problems.
The kidneys take care of some filtering of waste products made when our bodies digest protein , and there's some evidence to suggest that diets higher in protein put a greater strain on the kidneys to do this crucial job. A study found that the damage was only noticeable among people with early stages of kidney disease , particularly harmful because these people often are not aware their kidneys are affected, WebMD reported. You're dehydrated.
One of the waste products created by the kidneys during the filtering process is blood urea nitrogen. Researchers and physicians use blood urea nitrogen levels to evaluate kidney function , and it's also a measure of how hydrated a person is, WebMD reported.
Dehydration isn't necessarily a reason to avoid extra protein as long as water intake is increased simultaneously, she said. News U. Remember that fruits , vegetables , soups, and dairy products are also good sources of water.
