na te sayanasya nirudyamasya
brahman nu hartho yata eva bhogah
abhogino ’yam tava vipra dehah
piva yatas tad vada nah ksamam cet
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O brahmana, fully in knowledge of transcendence, you have nothing to do, and therefore you are lying down. It is also understood that you have no money for sense enjoyment. How then has your body become so fat? Under the circumstances, if you do not consider my question impudent, kindly explain how this has happened.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Generally those engaged in spiritual advancement take food only once, either in the afternoon or in the evening. If one takes food only once, naturally he does not become fat. The learned sage, however, was quite fat, and therefore Prahlada Maharaja was very much surprised. Because of being experienced in self-realization, a transcendentalist certainly becomes bright-faced. And one who is advanced in self-realization must be considered to possess the body of a brahmana. Because the bright-faced saintly person was lying down and not working and yet was quite fat, Prahlada Maharaja was puzzled and wanted to question him about this.
