Lifestyle does play a role in kidney health, but usually through several interconnected pathways rather than by directly “wearing out” the kidneys.
Obesity and physical inactivity can increase the likelihood of:
* high blood pressure
* insulin resistance
* type 2 diabetes
* cardiovascular disease.
All of these conditions can increase CKD risk. Obesity and smoking are themselves also recognized kidney-disease risk factors.
Regular activity, a balanced diet, maintaining an appropriate weight, and avoiding tobacco can therefore support kidney and cardiovascular health together.
## 6. What About High-Protein Diets?
This topic is often exaggerated online.
Eating protein does not automatically damage healthy kidneys, and high-protein diets should not be presented as a proven major cause of kidney failure in otherwise healthy young adults.
However, people who already have chronic kidney disease may need to adjust the amount and type of protein they eat because impaired kidneys have more difficulty handling certain metabolic waste products.
The National Kidney Foundation notes that people with CKD may need individualized management of protein, sodium, potassium, phosphorus, and other nutrients depending on their kidney function and blood tests.
Anyone with known kidney disease should therefore avoid making extreme dietary changes without medical or dietetic guidance.
