Serge didn't have any off or on seasons, no Bulk and Cut Periods, he stood shredded the whole year and had a special eating regiment.
Usually he ate 1-2 times a day, with having really big portions like up to 8 pounds of horse meat in one single sitting! He mostly ate during the late evening and never made breakfast as he was trainings his abs in the morning. Serge never counted his proteins but it was usually around 600 grams of proteins. Cheatmeals like pizza were not scripted in his diet but if his body craved for pizza, Serge didn't have a probleme having one. He never drink any shake during his competition days and consumed less carbs than proteins. Aditionally he took multivitamins.
Serge slept around 7-8 hours a night to get his body recovered from his long trainings sessions.
