A big part of the program is eating more calories to fuel growth and sustain progress. You simply have to accept that it is going to be more challenging for you to comply with that part of the program. You will need to be observant over what triggers your flare ups in terms of the sort of foods consumed, the macronutrient ratio etc. Many people have had some success by moving towards paleo, and supplementing with fish oil probably wouldnt hurt. When the flare ups occurr you will just have to take the effects on the chin and deload as necessary and build back up. It will take you more time, but you still should be able to maintain an overall upwards trajectory.
