Summary

This study will compare a carnivore diet (only animal foods) with a Mediterranean diet (fruits, veggies, grains, legumes) in 30 adults aged 30-60 with high LDL cholesterol. Over 3 weeks, researchers will measure how each diet affects cholesterol clumping, blood fats, and blood vessel function. The goal is to see which diet improves heart and metabolic health more.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Carnivore Diet and Mediterranean Diet
What this could lead to
If this trial succeeds, it could show which diet pattern better supports heart health in people with high cholesterol, guiding future dietary recommendations.
What could go wrong
This is a small, short-term study with only 30 participants over 3 weeks. Results may not apply to everyone, and longer-term effects or risks are not assessed.
