A few points:
1) eating fat is not what makes you fat.
2) if your goal is to get strong, you will need to eat enough to put on fat. Especially in the initial stages, if you were skinny to start with, fat gain is inevitable. It will slow down as you add more and more muscle.
3) genetics determines where you store fat. For you, you obviously naturally store fat around your belly. Join the club. That's life.
4) your goal is to 'get cut'. Starting Strength is not at all conducive to that goal. Starting strength will get you really strong, really fast, and allow you to add on a significant amount of muscular body weight.
5) if you decide that you would like to get big and strong, you better decide to say goodbye to your dreams of a six-pack - at least for the time being.
