I'm not a breakfast eater. I start every day with a cup of chai, but usually I don't eat anything until around 11-12. If I know I'm going to have a tough day, I might start with bacon and eggs. But usually any kind of food before 11 slows me down.
I tend to eat a biggish lunch, and then a smallish dinner. Our metabolisms slow down at night, so there's no need to load up during dinner.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
