I am a skinny guy so my problem is not keeping weight off but rather putting weight on. When I am deep into my work I put off eating and end up skipping meals.

My co-founders and I have started going to the gym for an hour or so every night which is a great break from work. Before it got cold and I started going to the gym I would sneak out for a 30min run every other day, a lot of great ideas come to me while running.
