Yes, there are times when it would be appropriate to briefly pause from the fast, but do so after consulting with the Holy Spirit. For example, last year when I was fasting I visited my son and his wife who live about 120 miles from me. My son is adopted from Ethiopia and three years ago he returned to Ethiopia and while there married a lovely woman. They now live in Seattle.
During my visit, she had prepared a very special Ethiopian meal for me (parents are very honored in Ethiopia) with lamb. I quickly consulted the Holy Spirit who showed me the way of love for her would be for me to pause my fast. She followed the meal with an Ethiopian Coffee Ceremony, again an act of honor toward me. I felt the freedom to engage in both the meal and coffee ceremony and then returned to my fast the next day. It was the loving thing to do .
