The Science: Why Some People Stay Slim No Matter What They Eat
In a landmark study published in Diabetes, researchers examined 26 pairs of identical twins, where one twin was overweight, and the other remained lean. The only significant difference between them? The lean twin had 25% more mitochondria than their obese sibling.
A separate 10-year Harvard study following 1,700 American women found that those with higher mitochondria levels remained slim, while those with lower levels gained an average of 44 pounds—despite eating the same number of calories.
Even more astonishing, animal studies at the University of Florida found that simply
increasing mitochondria levels led to a 60% reduction in fat mass—without changing diet or activity levels.
