If the gap between lunch and dinner has you agitated, unable to concentrate or just plain hangry, consider Rishi Sunak, who commits to a 36-hour “monk fast” each week. According to the Sunday Times, Sunak consumes no food from 5pm on a Sunday until 5am on a Tuesday, with water, tea or black coffee the only things to pass his lips.
Many people fast – for religious reasons, say, or for the potential health benefits. It has taken off in recent years due to diets such as the 5:2 (five days eating normally, two days eating 500 to 600 calories) and time-restricted eating (whereby people consume all their calories for the day in a fixed window).
