The Claim
Chronic consumption of a high-protein diet (2.51–3.32 g/kg/day) for one year in healthy, resistance-trained men results in no harmful effects on kidney function, liver enzymes, blood lipids, or body composition, despite a 32% increase in protein intake and higher total energy consumption.
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.
In healthy men who lift weights, eating a high-protein diet for a year does not damage the kidneys, liver, or blood fats, and does not change body composition, even though they eat more protein and more total calories than usual.

Chronic consumption of a high-protein diet (2.51–3.32 g/kg/day) for one year in healthy, resistance-trained men has no harmful effects on kidney function, liver enzymes, blood lipids, or body composition, despite a 32% increase in protein intake and higher total energy consumption.
When a person eats a lot more protein, the kidneys filter more waste products from the blood, and the liver and muscles use the extra amino acids to build and repair tissue instead of storing them as fat, so no damage occurs to organs or blood markers.
What the research says
1 studyFor healthy guys who lift weights, eating a lot of protein — even way more than recommended — for a whole year didn’t hurt their kidneys, liver, cholesterol, or make them gain fat, even though they ate more calories overall.
