I’m in relatively good shape for a programmer. I’m not overweight, but I have a little bit of extra fat, I usually shave it off during summer. As I got older, I noticed that it’s getting harder to get back in shape. After reading Hacking strength: Gaining muscle with least resistance & Least resistance weight loss by the excellent Matt Might, I started using MyFitnessPal, a food diary application. It has great ratings on Google Play Store with millions of downloads, and I managed to log a full week with it without going crazy.
