The Baal Shem Tov and his talmidim didn't preach abstinence from the pleasures of this world. Rather, the attitude was to enjoy the pleasures of this world, be always joyful and elevate everything to holiness.
So - eat gezunt! But li-shem shomayim in order to fulfill the dictum בכל דרכיך דעהו.
Know Hashem even when you eat:-)!!!
