In Bhagavad Gita Chapter 6, Verse 16, the speaker delivers a clear, uncompromising rule regarding physical rituals and spiritual practice: extreme physical austerities—specifically the practice of fasting—are completely useless for attaining spiritual growth or success in yoga.
While traditional folk practices (Lokved) often promote fasting as a pious act to please the Divine, the Bhagavad Gita explicitly rejects starving the body, placing it in the same category of self-defeat as overindulgence.
नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः । न चाति स्वप्नशीलस्य जाग्रतो नैव चार्जुन ॥ १६ ॥
Authentic Translation: "O Arjuna, yoga is not achieved by one who eats too much, nor by one who fasts completely; nor is it attained by one who sleeps excessively, nor by one who stays awake constantly."
In Gita 6.16, the speaker directly uses the phrase "Na caikantam anasnatah" (yoga is NOT attained by complete fasting/starving):
[ PHYSICAL EXTREMES ]
│
┌────────────────────────┴────────────────────────┐
▼ ▼
[ OVEREATING ] [ FASTING / STARVING ]
(Creates lethargy & physical discomfort) (Creates mental obsession & weakness)

[ YOGA IS IMPOSSIBLE ]
No. Bhagavad Gita 6.16 explicitly states that yoga and spiritual progress are impossible for someone who fasts (anasnatah). The Gita promotes regulated nourishment rather than starving the body.
Because fasting only torments the physical body without purifying the mind. It distracts the practitioner with hunger and fails to provide any spiritual benefit or liberation (Moksha).
