“If my kidney function is poor, should I eat as little meat as possible?”
This is one of the most common dietary questions among people with chronic kidney disease (CKD). After seeing elevated creatinine or a lower eGFR, many patients begin avoiding meat, eggs, soy products, or even adopt a very low-protein diet in the hope of reducing stress on the kidneys.
However, protein intake in CKD is not simply a matter of “the less, the better.”
Excessive protein intake may increase the metabolic workload on the kidneys, while inadequate intake can increase the risk of malnutrition, muscle loss, and sarcopenia. This is particularly important for older adults, patients with poor appetite or unintentional weight loss, and those receiving dialysis. [1–3]
The appropriate amount of protein therefore depends on CKD stage, dialysis status, diabetes, nutritional status, and the presence or risk of sarcopenia.
How Much Protein Should a Person With Chronic Kidney Disease Eat Per Day?
According to the KDIGO 2024 Clinical Practice Guideline, adults with CKD stages G3 to G5 who are not receiving dialysis may generally aim for approximately 0.8 g of protein per kilogram of body weight per day. [1]
The American Diabetes Association Standards of Care in Diabetes—2026 also recommends approximately 0.8 g/kg/day for people with CKD stage G3 or higher. For individuals receiving dialysis, approximately 1.0–1.2 g/kg/day should be considered. [2]
For example, for a 60-kg patient for whom a target of 0.8 g/kg/day is appropriate:
60 × 0.8 = 48 grams of protein per day.
Importantly, 48 grams of protein does not mean 48 grams of meat.
The actual protein content of meat, fish, eggs, soy products, and dairy products must be considered when planning meals. [1]
Does Poor Kidney Function Always Mean You Need a Low-Protein Diet?
Not necessarily.
Recommendations regarding the degree of protein restriction differ somewhat among kidney nutrition guidelines.
KDIGO 2024 suggests maintaining protein intake at approximately 0.8 g/kg/day for adults with CKD stages G3 to G5 and avoiding high protein intake above 1.3 g/kg/day. More intensive protein restriction may be considered only in selected patients at higher risk of kidney failure who are willing and able to follow the diet under close professional supervision. [1]
The KDOQI 2020 nutrition guideline takes a more restrictive approach in selected metabolically stable patients. It recommends approximately 0.55–0.60 g/kg/day for certain non-dialysis CKD stage 3–5 patients without diabetes and suggests approximately 0.6–0.8 g/kg/day for those with diabetes. [3]
Therefore, patients should not automatically reduce protein intake to extremely low levels simply because kidney function is abnormal.
The appropriate target must balance the risk of CKD progression against the risks of malnutrition and muscle loss.
Can People With CKD Follow a High-Protein Diet?
In general, people with chronic kidney disease should avoid starting a high-protein diet without professional guidance.
KDIGO 2024 recommends avoiding protein intake above approximately 1.3 g/kg/day in adults with CKD who are at risk of disease progression. [1]
High-protein diets, whey protein supplements, and large amounts of meat are common among people trying to build muscle, but these approaches should not automatically be applied to people with CKD.
Before increasing protein intake, it is important to consider eGFR, albuminuria or proteinuria, current dietary intake, body weight, and nutritional status.
The goal is not to eliminate protein but to avoid chronically consuming substantially more than the body requires.
Do People With Diabetic Kidney Disease Need an Even Lower Protein Intake?
Not necessarily.
The ADA 2026 Standards of Care recommend approximately 0.8 g/kg/day for people with CKD stage G3 or higher. In people with diabetes and CKD, reducing protein intake below 0.8 g/kg/day has not been shown to improve glycemic control, cardiovascular risk measures, or the course of GFR decline. [2]
Therefore, nutrition management in diabetic kidney disease should not focus only on reducing protein.
Blood glucose, blood pressure, albuminuria, total calorie intake, sodium intake, and overall diet quality all contribute to long-term kidney and cardiovascular health.
Why Do Dialysis Patients Need More Protein?
This is a common source of confusion.
“If protein needs to be controlled before dialysis, why should I eat more after dialysis begins?”
The nutritional situation changes after dialysis starts.
Dialysis patients are at increased risk of protein-energy wasting due to factors such as treatment-related nutrient losses, chronic inflammation, poor appetite, and metabolic changes.
For this reason, protein requirements are generally higher in dialysis patients than in people with non-dialysis CKD.
The ADA 2026 Standards of Care recommend considering approximately 1.0–1.2 g/kg/day of protein for individuals receiving dialysis. [2]
This is why the simple statement “kidney disease means eating less protein” does not apply to every patient or every stage of kidney disease.
What if Chronic Kidney Disease Is Accompanied by Sarcopenia?
This is especially important in older adults with CKD.
If a patient already has sarcopenia, frailty, unintentional weight loss, poor appetite, cachexia, or malnutrition, protein restriction needs to be approached much more cautiously.
KDIGO 2024 advises against prescribing low- or very low-protein diets to metabolically unstable people with CKD. The guideline also recognizes the potential adverse consequences of protein restriction in people with sarcopenia, cachexia, or undernutrition. [1]
The clinically important question is therefore:
What is the more immediate risk — progression of kidney disease, or worsening malnutrition and muscle loss?
If kidney function is relatively stable but the patient is losing weight, muscle strength, walking speed, or physical function, a standard low-protein approach should not be applied automatically.
What Are the Signs of Sarcopenia in CKD?
Patients with chronic kidney disease should be assessed for sarcopenia or malnutrition when they develop:
• Progressive weight loss
• Visible loss of muscle in the arms or legs
• Reduced grip strength
• Increasing difficulty standing from a chair
• Slower walking speed
• Increased fatigue or reduced activity
• Poor appetite
Nutritional assessment should not rely on a single blood test. Changes in body weight, dietary intake, muscle mass, muscle strength, and physical function should also be considered.
Can CKD Patients Start a Low-Protein Diet on Their Own?
Strict low-protein or very low-protein diets should not be started without professional guidance.
KDOQI emphasizes that protein restriction requires adequate energy intake. If total calorie intake is insufficient, the body may break down its own tissues for energy, increasing the risk of malnutrition and muscle loss. [3]
This is particularly important for older adults, patients with poor appetite or recent weight loss, those with sarcopenia, and people receiving dialysis.
Ideally, protein targets should be established with a physician and renal dietitian based on CKD stage, body weight, eGFR, proteinuria, dietary intake, and nutritional status.
Can Traditional Chinese Medicine Help CKD Patients With Sarcopenia?
From a Traditional Chinese Medicine perspective, CKD accompanied by muscle loss, fatigue, poor appetite, and reduced physical function may be assessed according to individual patterns such as spleen and kidney deficiency, qi and blood deficiency, dampness, or blood stasis.
Clinical research has also begun to examine Traditional Chinese Medicine interventions for sarcopenia in dialysis patients.
A randomized, double-blind, placebo-controlled trial published in Phytomedicine in 2025 enrolled 128 dialysis patients with sarcopenia. Participants received Shen-Qi Paste or placebo for 12 weeks, while both groups also performed low-intensity exercise. The study reported greater improvement in some outcomes, including skeletal muscle mass index, in the Shen-Qi Paste group. [4]
A 2024 systematic review and meta-analysis of Chinese herbal medicine for sarcopenia included 17 randomized controlled trials involving 1,440 participants. The analysis reported potential improvements in muscle mass, grip strength, and some measures of physical function. [5]
However, high-quality evidence specifically involving CKD or dialysis patients with sarcopenia remains limited. These findings do not mean that the same herbal treatment is appropriate for every patient.
Can CKD Patients Take Chinese Herbal Medicine to “Tonify the Kidneys” or Build Muscle?
Self-medication is not recommended.
Patients with chronic kidney disease may have reduced kidney function and often take multiple medications for hypertension, diabetes, cardiovascular disease, and other conditions.
Chinese herbal treatment therefore needs to take kidney function, electrolyte status, existing medications, potential herb-drug interactions, and the individual TCM pattern into account.
For CKD patients with sarcopenia, Traditional Chinese Medicine is best considered as part of an integrated treatment plan rather than a replacement for nutritional therapy, exercise, or standard nephrology care.
FAQ: Common Questions About Protein Intake in Chronic Kidney Disease
Q1: How Much Protein Can I Eat if My Kidney Function Is Poor?
For adults with non-dialysis CKD stages G3 to G5, approximately 0.8 g/kg/day is commonly used as a general reference. However, the actual target should be individualized according to CKD stage, diabetes, nutritional status, and risk of sarcopenia. [1,2]
Q2: How Much Protein Can a 60-kg CKD Patient Eat Per Day?
If a target of 0.8 g/kg/day is appropriate, a 60-kg patient would consume approximately 48 grams of protein per day. However, 48 grams of protein does not equal 48 grams of meat. [1]
Q3: Can People With Poor Kidney Function Drink Whey Protein?
It depends on the individual situation. People with CKD should generally avoid excessive protein intake. If whey protein is being considered for exercise, sarcopenia, or nutritional support, total protein intake and kidney function should be assessed first.
Q4: Do Dialysis Patients Still Need a Low-Protein Diet?
Usually not. Dialysis patients generally have higher protein requirements because of the risk of protein-energy wasting and malnutrition. The ADA 2026 Standards of Care recommend considering approximately 1.0–1.2 g/kg/day. [2]
Q5: If I Have CKD and Sarcopenia, Should I Protect My Kidneys or Increase Protein Intake?
Both need to be considered.
When significant sarcopenia, frailty, or malnutrition is present, a standard low-protein diet should not be applied automatically. Treatment should balance slowing kidney disease progression with preserving muscle mass, nutritional status, and physical function. [1,3]
The most important point in CKD nutrition is that protein requirements are not the same for every patient.
People with non-dialysis CKD generally need to avoid excessive protein intake. Dialysis patients often require more protein to reduce the risk of protein-energy wasting. Older adults and patients with sarcopenia or malnutrition should not sacrifice muscle and nutritional status simply to achieve stricter protein restriction.
The most appropriate protein target should therefore be based on kidney function, CKD progression, dialysis status, nutritional risk, and the patient’s overall clinical condition.
