We can definitely see that to advance in Kṛṣṇa consciousness one must control his bodily weight. If one becomes too fat, it is to be assumed that he is not advancing spiritually. ÅšrÄ«la BhaktisiddhÄnta SarasvatÄ« ṬhÄkura severely criticized his fat disciples. The idea is that one who intends to advance in Kṛṣṇa consciousness must not eat very much. Devotees used to go to forests, high hills or mountains on pilgrimages, but such severe austerities are not possible in these days. One should instead eat only prasÄda and no more than required. According to the Vaiṣṇava calendar, there are many fasts, such as EkÄdaśī and the appearance and disappearance days of God and His devotees. All of these are meant to decrease the fat within the body so that one will not sleep more than desired and will not become inactive and lazy. Overindulgence in food will cause a man to sleep more than required. This human form of life is meant for austerity, and austerity means controlling sex, food intake, etc. In this way time can be saved for spiritual activity, and one can purify himself both externally and internally. Thus both body and mind can be cleansed.
