Researchers have developed a new drug approach that prevented mice from becoming obese even after prolonged exposure to a high-fat, sugar-rich diet. The study focused on blocking the MRS2 gene linked to magnesium movement inside mitochondria, helping cells burn fat and sugar more efficiently

A new drug kept mice from becoming obese even after long-term exposure to a sugar-rich, fat-heavy diet.

The work points to magnesium movement inside mitochondria, the energy-producing structures found in cells.

When magnesium enters mitochondria through a gene called MRS2, it can slow the cell's ability to burn sugar and fat. Researchers removed the MRS2 gene in mice.

After 52 weeks of a fat-heavy diet, normal mice gained weight and developed signs of metabolic disease, while mice without MRS2 stayed lean.
