Happy new year! Given the eating binge you may of had at xmas, here’s a free diet book that I thoroughly recommend:
“The Hackers Diet” by AutoDesk creator John Walker
I found this very helpful a few years back when I needed to drop a few(!) pounds myself, it does a good job of explaining weight control from an engineers perspective. Since then, I’m a firm believer in ‘eat less, exercise more’ and try to avoid the extreme forms of ‘eat less’ (i.e. being on a diet) at all costs!
