Besides discouraging fasting, did Baba offer any guidance on the right amount of food to eat?

Yes, Sai Baba advocated for a balanced approach to eating, discouraging both extremes of deprivation and overindulgence. While he was strongly against fasting, which he called "terrible" and a cause of "continuous discomfort," he also cautioned that "Excessive eating is also not beneficial." Chapter 32 clearly states his recommendation: "Moderate eating is truly comfortable." This shows that Baba's guidance was not simply to eat, but to eat in a way that brings comfort and strength to the body, thereby making it a suitable vehicle for spiritual pursuits, rather than a source of distraction or weakness.
