Of course, this SNP isn’t entirely to blame if you have weight problems. Your dietary choices, activity level, and other genetic variants also come into play. One study showed that this FTO SNP is associated with an average increase in weight of 7lbs. Another study linked it to an increase of 1.4 to 2.8 BMI points.[ref][ref]
- A/A: higher risk of obesity, increased BMI
- A/T: increased risk of obesity, increased BMI
- T/T: normal
