Should I consume fatty foods with Accutane pill even though fatty food like peanut butter and avocados make me breakout? (photo)

I've been taking accutane for about 1month and 3weeks. My skin is no longer oily and i do not have one single blackheads. On the other hand i've been having cysts on my left cheek for quite some time now (i had around 3 and have 2 currently). Overall fatty foods (peanut butter, nuts, avocado, oils) make me breakout, i've adopted a high carb low fat vegan. Should i take accutane with a fat dense meal even though fatty foods make me breakout?
