Why does aspartame make you fat?

Aspartame itself does not directly cause weight gain; it is a low-calorie artificial sweetener used to replace sugar in many products. However, some studies suggest that consuming aspartame might lead to increased cravings for sweet or high-calorie foods, potentially resulting in overeating. Additionally, the psychological effect of consuming "diet" foods may lead some individuals to indulge more, offsetting any calorie savings. Ultimately, the impact of aspartame on weight can vary among individuals based on their overall diet and lifestyle.
