Sikhism
Sikhism is one of the two religions that does not promote fasting except for medical reasons. In fact, it rejects fasting terming it ‘a blind ritual’. The Sikh gurus discourage their followers from engaging in fasting as those who observe fast are considered to be “rewarded with less than a shell” according to the holy Scripture of Sikhism, the Guru Granth Sahib. So, mostly Sikhs never undertake a fast of any kind.
