Question

Studies have shown that people who carry the FTO gene may experience higher levels of hunger and have a greater tendency to overeat. Although the FTO gene has been linked to obesity, it is not the sole gene responsible for body weight regulation. The thrifty gene hypothesis suggests that certain genetic variations evolved to help humans store energy during times of famine, but in modern times, high-calorie foods are more readily available, leading to overeating and weight gain. The prevalence of the FTO gene varies among populations, but it is estimated that approximately 40% of Europeans carry at least one copy of the gene.
