Straight off the British Isles is another import. It’s not the Beatles or the Rolling Stones; it’s “the fasting diet” and it’s hot. The diet was covered recently by a BBC documentary.
It purports to help patients lose weight quickly by slashing their dietary intake on 2 non-consecutive days per week. This is not a total fast, mind you, just a serious reduction in calories on those 2 days: 600 calories for men and 500 calories for women. To sum it up, for 5 days you eat what you normally consume (don’t gorge, obviously), and on 2 days during the week, not in a row, you do a reduced-calorie fast.
