Ask HN: Best practice to stay healthy?

For the past few years I've been doing the most boring thing but it works. I'm eating minimally processed foods, sticking mainly with vegetables, fruits, and meat, avoiding bread, pasta, and any drink with calories.

For exercise I've been focusing on weight training, specifically compound movements with a barbell (squats, presses, cleans, pulls) and HIIT for cardio. I had been working out at home but recently I joined a CrossFit gym and I like it better.
