Having a healthy and complete body is one of the ways of serving Hashem.
היות הגוף בריא ושלם מדרכי עבודת השם הוא
היות הגוף (hiyot ha'guf) means "the body being."
בריא ושלם (bari v'shalem) means "healthy and complete" (or whole).
מדרכי עבודת השם (midarchei avodat Hashem) means "from the ways of serving Hashem."
הוא (hu) means "is."
This statement reflects the idea, found in various Jewish teachings, that maintaining one's physical health is not just a personal responsibility but a component of serving Hashem. The idea is that a healthy body allows a person to fulfill mitzvot, study Torah, and engage in acts of kindness with greater energy and focus. It emphasizes that caring for one's physical well-being is integral to a life of spiritual service. This concept is famously mentioned in Rambam's (Maimonides) writings, where he discusses the importance of a healthy lifestyle as part of divine service.
