Yeah i do basically all protein and fiber. The key is to keep your insulin response low. I was loosing a kilo a week back in june when i was strict with it. Good thing is protein really fills you up and stops the production of hormones that tell your body "im hungry" even though you just ate a bag of chips and three migoreng sachets. (Speaking of my old eating habits)
Also get good sleep that cuts down cortisol and boosts serotonin. Also stress goes down and so does anxiety. Good all around.
