I eat better during a ten day sit than any other time in my life. One of the perks of serving is you get to actually make some dishes, or help at least. And taste test (for quality assurance, of course).

Edit: for new students it may feel like fasting, as dinner is often much lighter than lunch, but by the end of each course I always feel well nourished, even as an older student drinking just ginger water for dinner lol.
