Average BMI in the UK (I think thats where the video is from) rose from 22-23 in 1984 to 27-28 in 2014. Genetics cannot explain such a large change in just 30 years any more than it can explain the concept of people losing weight through dieting or for example why BMI in Germany is higher than France. BMI varies across short time spans because attitudes can change in 30 years even though genes dont. BMI varies between neighboring countries because attitudes and customs vary even if genes dont.
You are not a victim of your genes.
