High-Fat Diets Disrupt Metabolism, Lead to Weight Gain
Imagine your body's cells are like tiny factories.
Eating too much fatty food can mess up these factories.
Researchers found that a high-fat diet can cause these factories to make too many harmful molecules and become resistant to insulin, leading to weight gain.
But, scientists also discovered that giving mice an antioxidant can help fix some of the problems.
This is because the antioxidant helps the factories work better and reduces the amount of harmful molecules, bringing them back to a healthier state.
High-fat diets cause metabolic dysfunction at the cellular level.
Mice on high-fat diets developed weight gain and insulin resistance.
Researchers mapped changes to metabolic enzymes.
Metabolic enzyme dysregulation involves sugar, lipid, and protein metabolism.
Antioxidant treatment reversed many negative effects.
