New Delhi, Mar 14: While protein shakes, protein bars and high-protein meal plans have become increasingly popular among fitness enthusiasts, medical experts caution that excessive protein intake may place added stress on the kidneys.
According to Saiprasad Sahoo, protein is essential for muscle repair and overall health, but consuming it in excessive amounts can burden the body’s filtration system.
“Kidneys play a crucial role in clearing nitrogen waste formed during protein metabolism. When protein intake goes far beyond the body’s requirements, the kidneys are forced to work harder for long periods,” said Dr Sahoo of Manipal Hospital Bhubaneswar.
When the body breaks down protein, nitrogen-based waste products are produced, which must be filtered out of the bloodstream by the kidneys. A consistently high intake of protein means these organs must eliminate larger quantities of waste, increasing their workload over time.
Experts warn that the risk may be greater for people who already have undiagnosed kidney conditions. While healthy individuals can usually tolerate moderate increases in protein consumption, a sudden surge in intake could worsen hidden kidney problems.
Dr Sahoo said some individuals may appear healthy but could have early kidney issues that remain undetected. In such cases, aggressive high-protein diets may accelerate stress on already vulnerable kidneys.
Another concern is the increasing use of protein supplements such as shakes and powders. These products, often promoted in restrictive fitness diets, can lead people to consume far more protein than they would through a normal balanced diet.
According to experts, extreme high-protein diets may also create nutritional imbalances. Such diets can sometimes lack adequate fibre, carbohydrates and essential vitamins or minerals, which may affect digestion, energy levels and overall health.
Health specialists emphasise that protein is only one component of a healthy diet and should not be consumed excessively in pursuit of fitness goals.
“Fitness goals should never come at the cost of health. Adequate hydration, balanced meals and professional guidance are essential before increasing protein intake,” Dr Sahoo advised.
