Hi all,
just looking for some pointers that might have worked for you. I'm wondering about what I need to eat to lose fat AND build muscle. It's a bit confusing

I've heard people have phases where they work on losing fat and once that is down, they THEN eat and train to put on mass etc etc.
My goal is not to compete, so I don't want to be too regimented about my diet. I would like to have some more upper body muscle and definition and lose fat.
Is it possible to eat to lose fat AND build muscle at the same time or is that just too difficult?
(in the last four months, I've had a balanced diet low in fat, protein shake after training and I've LOST fat and LOST weight rather than gain it - but look better???)
Any advice on your experiences appreciated, thanks
