* Make exercise a part of your daily routine to the point you’re not thinking about it, ie cycling to and from work. * Eating clean. So cooking all your meals with fresh ingredients. * Get involved in a sport you enjoy doing. I notice people punish themselves, ie running when they don’t like it. It’ll never work long term. Climbing seems to sit well with the IT crowd. Find what works for you. * It takes time. Potentially years to get where you want to be. Being patient is important. On the more extreme side * Move country. I had a healthier lifestyle in Indonesia than I did in London. Lack of alcohol and chocolate snacks is something you get used to when it’s not accessible.
