This is what I was getting at. I am sure there is a small segment of the population that it is impossible for. I am sure there is another large segment of the population that it is impossible for them, meaning they don't have the dedication to accomplish it. There is nothing wrong with that. I was and still mostly am one of those guys LouisEly spoke of who is at the gym religiously but was platoed for years. The problem (and this is just me specifically) wasn't that I had reached my peak due to test levels. The problem was that I would drink and eat as much as I wanted every weekend and wasn't getting enough protein. And I was fine with that (still am) since I am youngish and like to have fun with my friends. I am sure there is some truth to what LouisEly is saying, he is in the business so he knows more about it than the rest of us as far as I can tell, but I think he accidentally overestimated things. I would guess there is an extremely small segment of the population that has actually reached their genetic limit. For nearly everyone who thinks they have reached that limit, they could probably work out more effectively, eat more protein, or eliminate a cheat meal and have more success. Back to the original topic though, I don't think Fish Oil in and of itself will do much of anything for fat loss. You should take it to be healthy though. If I wanted to lose some weight, I would work out at least 3 times a week (cardio and weights), eat as much veggies and meat as I could but still at a caloric deficiency, and supplement with just whey protein. Most people will probably also say Omega 3s and a multivitamin as well and they are probably right.
