Is FTO useful for menopause?

The question of whether FTO is useful for menopause cannot be answered affirmatively with current evidence. FTO (fat mass and obesity-associated gene) is one of the most well-studied obesity risk genes, but its average effect is only about 1–2 kg body weight (human-strong, GWAS). Menopause involves hormonal shifts that affect metabolism and fat distribution, but there is no robust evidence that FTO variants directly predict or influence weight changes during this transition. Most FTO studies focus on general populations, not specifically on menopause. Moreover, lifestyle factors (diet, exercise) dominate weight management during menopause. Therefore, testing for FTO alone is not clinically useful for menopause-related weight concerns. The evidence is best classified as 'unclear' due to lack of direct studies. Caveat: Do not base clinical decisions on this single marker.
