Yes I used all the crap you mentioned. I was having fish oils, both supplemental form and from fish like Tuna etc...several times a day. I would have flaxseed caps too.
My vitamins were taken, did the low fat route by cutting all visible fat off steak, pork chops or no skin on the chicken. My shakes were low fat, the milk was non-fat.
Every meal was no less than 2-3 hours apart. With the last two meals being as close to pure protein (all meat and maybe some veggies) as possible. Cottage cheese usually finished my night, every night.
I was doing many sessions of cardio, usually one 30-40min session in the morning on an empty stomach, and then again about 2 hours before bed, in which I'd rest 30min before eating and then eat, hit the sack.
IMO, carbs are just evil. They sure as hell taste great, but they're evil from many views.
Again, there is NO such thing as an essential carbohydrate!
