Which of the following is NOT listed as a reason for being overweight?

Eating healthy meal options is considered beneficial for maintaining or achieving a healthy weight rather than a contributing factor to being overweight. Nutrition experts emphasize that a balanced diet enriched with whole foods, fruits, vegetables, lean proteins, and healthy fats supports weight management and overall health. In contrast, the other factors listed, like genetics, fast food consumption, and under eating, can contribute to an imbalance in energy intake and expenditure, leading to weight gain or difficulty losing weight. Genetics may predispose individuals to certain body types or metabolic rates, fast food often contains high levels of calories, fats, and sugars, and under eating can disrupt metabolism and lead to compensatory overeating later, all of which can contribute to being overweight.
