The Claim
In overweight and obese adults who have baseline hyperfiltration, defined as an estimated glomerular filtration rate (eGFR) greater than 120 mL/min/1.73 m², participation in a high-protein weight loss program is associated with a median reduction in eGFR of 8 mL/min/1.73 m², which may indicate a return toward normal glomerular filtration rather than the development of kidney dysfunction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're overweight and your kidneys are working too hard at the start, going on a high-protein diet to lose weight might make your kidney function look more normal—not worse—by bringing down their overactivity.
See the scientific wording
In overweight and obese adults with baseline hyperfiltration (eGFR >120 mL/min/1.73 m²), a high-protein weight loss program is associated with a median reduction in eGFR of 8 mL/min/1.73 m², suggesting a normalization of glomerular filtration rather than renal impairment.
What the research says
1 studyThe study looked at a high-protein diet in overweight people with high kidney filtration and found it didn’t hurt their kidneys. This supports the idea that the drop in filtration is normal, not harmful.
