23andMe’s genotyping results has provided scientific support for something I’ve been telling people over the years without many believing me… that I can become fat. At 5’2″ and 108 lbs. of a marathon runner’s body, I can’t say I blame them. I don’t look like much at this weight, never mind the 90 lbs. I used to be at before I started distance running 16 years ago. Yet, I can eat a lot, with consequences almost like any over typical person if I don’t run it all off.

When I first started learning about genetics for 23andMe’s genotyping services, I started on their site where there was some material. One of the articles was on variations, and more specifically, the “speed gene” with the scientific name of ACTN3. Being a multiple marathon runner who knew I was more of the fast twitch muscle variety for short bursts of speed rather than endurance running, I wanted to know if I, indeed, had this gene and was going to check on it among the first things I do, unless it were really hard to find. To be more correct, I wanted to know if I had the correct configuration of this gene. Everybody has this gene. It’s just a matter of which configuration it was in to enable the benefit of physical speed and power.
