BITESIZE: Ketogenic Diet Dangerous? Breaking Down the New Study
Notas del episodio
A new study claims ketogenic diets cause liver damage and early death. Here’s what you need to know.
A 2025 mouse study recently made headlines, warning that ketogenic diets may lead to fatty liver, high triglycerides, and a shortened lifespan.
But here’s the catch:
These findings were in genetically altered mice fed a 90% fat diet, filled with highly synthetic components, and they contradict what human trials have shown again and again.
In real people, ketogenic diets have consistently been linked to:
✅ Lower liver fat and improved liver enzymes
✅ Reduced triglycerides
✅ Improved insulin sensitivity and A1c
✅ Medication reduction or even remission in type 2 diabetes
So why the disconnect?
In this video, Dr. Bret Scher breaks it down:
- What the mouse study really showed (and what it didn’t)
- Key biological differences between mice and humans
- Why human evidence still supports a well-formulated ketogenic diet’s safety and benefits
- What to look for when evaluating nutrition headlines
Animal data can provide hints and raise important questions, but when human trials show clear benefits, that’s the signal we should trust.
