24-h severe energy restriction impairs postprandial glycaemic control in young, lean males

Intermittent energy restriction (IER) involves short periods of severe energy restriction interspersed with periods of adequate energy intake, and can induce weight loss. Insulin sensitivity is impaired by short-term, complete energy restriction, but the effects of IER are not well known. In randomised order, fourteen lean men (age: 25 ( sd 4) years; BMI: 24 ( sd 2) kg/m 2 ; body fat: 17 (4) %) consumed 24-h diets providing 100 % (10 441 ( sd...
