on the way the altered mitochondrial membranes found in people with metabolic diseases such as Barth syndrome, a rare genetic disorder that weakens the heart, fail to enable cellular power production.

An apple-shaped body could also be a major red flag for your heart. A 2021 review of 31 studies found that extra weight around the midsection is directly tied to a higher risk of heart disease.
