Why? When? and How? Should I Fast

Three frameworks for fasting practices: daily circadian rhythm fasting (10-14 hours), monthly Ekadashi fasting (36 hours twice monthly), and yearly seasonal fasting (36-100 hours).

Scientific Explanation: Discusses telomeres -- protective DNA caps that shorten with cell division. The more telomeres, the longer you live. Research suggests caloric restriction and plant-based eating help preserve telomeric length and extend lifespan.

Astronomical Explanation: Emphasizes alignment with natural circadian rhythms and lunar cycles. Recommends consuming most nutrition before 3 PM and fasting during Ekadashi (the 11th lunar day) because grains retain water affected by moon gravitational pull.

Spiritual Explanation: References the Bhagavadgita's concept of Upavas -- drawing closer to spiritual consciousness through disciplined fasting practices combined with meditation and service.
