Low-Protein Diet With Low-Protein Foods Versus a LPD Without LP Foods in Patients With Chronic Kidney Disease (CKD)

This study is comparing two types of low-protein diets for people with chronic kidney disease (CKD): one that uses specially formulated low-protein food products, and one that reduces protein intake through regular food choices alone. Eating less protein can help slow the progression of kidney disease, but it can be hard to stick to. Researchers want to see which approach works better for patients. **You may be eligible if...** - You have stage 3a to 5 chronic kidney disease and are not on dialysis - You are currently eating more than 1g of protein per kilogram of body weight per day - You are in good nutritional status (not malnourished) - You have not tried a low-protein diet before - You are motivated to change your eating habits - You have health insurance coverage (France-based study) **You may NOT be eligible if...** - You are expected to start dialysis or receive a kidney transplant within 12 months - You have a known allergy to milk, eggs, soy, or nuts (ingredients in special diet products) - Your diabetes is poorly controlled (HbA1c above 8.5%) - You have active cancer, active infection, or an uncontrolled inflammatory disease - You have a psychiatric condition preventing you from following the protocol - You are currently enrolled in another clinical trial Talk to your doctor to see if this trial is right for you.
