Bhagavad Gita 6.16

Yoga is not for one who overeats or starves, nor for one who sleeps too much or never sleeps.

नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः ।
न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन ॥

natyasnatas tu yogo 'sti na caikantam anasnatah |
na catisvapnasilasya jagrato naiva carjuna ||

Yoga is not for one who overeats or starves, nor for one who sleeps too much or never sleeps.

Food and sleep change messengers. A verse is not a diet plan. A physician still belongs.
