The Claim

In obese older adults with age-normal renal function (eGFR ≥ 45 mL/min/1.73m²), a hypocaloric diet with higher protein intake (1.2 g/kg body weight/day) for 6 months does not impair renal function, as measured by unchanged estimated glomerular filtration rate (eGFR) and blood urea nitrogen (BUN) levels compared to a control group consuming 0.8 g/kg body weight/day.

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.

Cause and effect
1 study reviewed
In plain English

For overweight older people with normal kidney function, eating a low-calorie diet with more protein for six months doesn't harm their kidneys, compared to eating less protein.

  1. Study: Markers of Renal Function are Unchanged in Obese Older Adults Consuming a Higher Protein, Hypocaloric Diet for 6 Months

    The study gave older overweight people a diet with more protein while they lost weight for 6 months and found it didn't harm their kidney function, just like the claim says.
