Question: What were his favourite foods?
Response: You might be surprised that he relished good food. He was from Andhra and so, relished food that was hot and spicy. He was very fond of sweets and would eat them in great quantities. With all this he would always have ghee. Ghee formed a very important part of his diet and whatever the food, it would be accompanied with large quantities of ghee.
Of course, he was also doing Āsana for three to four hours daily in addition to his Prāṇāyāma. His practice was extremely rigorous and that may account for his being able to handle these large quantities of spicy and sweet foods.”
