Arnold Schwarzenegger Uncovers Link Between Protein Consumption and Kidney Stones

Arnold Schwarzenegger has been busting dieting myths in his fitness newsletter since 2023. The 76-year-old bodybuilding legend has highlighted the need for adequate protein consumption. However, despite the benefits, various myths surround the building blocks of our muscles. In the latest edition of Arnold’s Pump Club, the former Mr. Olympia exposed yet another one.

You may have heard one of the most common protein myths, stating excess intake stresses the liver. However, this time, Arnold Schwarzenegger discussed the myth linking protein intake to kidney stones. Kidney stones are formed when your urine contains excess crystal-forming substances like calcium, oxalates, and uric acid. However, the myth says protein contributes to it.

However, Arnold Schwarzenegger provided evidence that states such an assumption is false. “Studies suggest that higher-protein diets are not a direct cause of kidney stones,” Arnie explained in his newsletter. Yet, it also hinted at why such a myth took root. “Ignoring other nutritional needs while eating more protein could increase your risk,” said the bodybuilding icon.

The study uncovered that kidney stones are linked to a sedentary lifestyle and obesity. So proper exercise and nutrition are essential to preventing the painful condition. They also found that lack of a balanced diet and chronic dehydration were triggers for kidney stone formation. 

“Some research suggests too much animal protein is associated with kidney stones,” wrote Arnold Schwarzenegger. However, those who drank enough water and had all their macro and micronutrients didn’t develop stones despite consuming excess animal protein. Besides not harming your kidneys, Schwarzenegger has cited the many benefits of protein.

The 76-year-old bodybuilding legend once advised everyone to take protein powders if their diet lacked adequate amounts. “Protein is not just for bodybuilders,” Arnie wrote in his Instagram story. Schwarzenegger advised that people, who are looking to lose weight and preserve muscle need to increase protein. He also said that protein helps people better blood glucose and lipid profiles.

The Terminator highlighted several other benefits of protein, including better hunger regulation and immunity. Arnold Schwarzenegger even cited a study that showed those who took more protein showed healthier signs of aging. The researchers found that these individuals showed lower chances of developing nearly a dozen chronic cognitive and physical diseases.

Protein is among the most important macronutrients out there. Arnold Schwarzenegger doesn’t want people to be deficient in this essential nutrient thanks to unproven myths.
