It promises weight loss and tight abs with no restrictions on the foods you eat. Sooner or later, carb-cutters will crave cakes, the fat-avoiders will be unable to resist the cheese board and fasters will just feel too hungry to carry on.

Which is why “flexible dieting” is such an attractive proposition.
