Obesity is associated with glomerular hyperfiltration leading to renal impairment and is a risk factor for the progression of kidney disease.Weight loss can reduce proteinuria and improve eGFR.Intermittent fasting is safe and effective, and in addition to improving body shape and weight in obese patients, it can also improve glucolipid metabolism, reduce proteinuria, improve kidney function and delay the progression of kidney disease.
KDOQI clinical practice guideline for nutrition in chronic kidney disease (CKD) uses a low-protein diet to reduce renal impairment and delay progression. The current research hotspot is dietary intervention. Time-restricted feeding was used to intervene in the progression of CKD. It restrict the time of eating but not the eaten calories, which have a higher compliance and safety. Studies have shown that intermittent fasting in obese patients with CKD is not only reduce body weight, but also improves glycolipid metabolism, reduces proteinuria and delays the progression of kidney disease. Intermittent fasting is currently a scientific research hotspot, and there are few international studies on the implementation of intermittent fasting to delay the deterioration of renal function in obese CKD patients, and lack of data on Chinese patients, which has great research potential. Based on the above background, this study was conducted as an pilot clinical trial to explore the effects of intermittent fasting on obese patients with CKD and to observe its effectiveness, safety and compliance.
