Weight management is more urgent than ever due to the burgeoning obesity epidemic and its consequences. As hard as many people strive to lose fat stores, the extra pounds somehow sneak back uninvited. Researchers are finding that there is more to weight gain than just what we eat or how we exercise. Many factors can stealthily conspire to pack on weight, gradually or suddenly. They do include dietary and activity choices, but underlying health conditions may also factor in.


1. Low-Calorie Sweeteners

In small amounts, artificial sweeteners such as sucralose and aspartame may assist in weight loss and enhance metabolism. However, George Washington University scientists found that these alternatives could also cause our bodies to create and store fat. Their stem cell studies suggest that these sweeteners heighten the activity of glucose transporters, genes that increase glucose entry into fat cells.
