Meat-Only vs. mediterranean: which diet wins for your heart?
NCT ID NCT07462871
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
