Study Arms (2)

Mediterranean diet plus intermittent fasting

EXPERIMENTAL

For 4 weeks participants will be encouraged to adopt the Mediterranean dietary guidelines as recommended by the Mediterranean Diet Foundation in Barcelona, Spain. In combination with these guidelines, an intermittent fasting regime involving two days of the week will be implemented. The regime will encourage individuals to consume of 500kcal per day for women and 625kcal per day for men, resulting in 75% daily caloric restriction during each of these two days.

Behavioral: Mediterranean diet guidelines plus intermittent fasting

Eatwell guide plus intermittent fasting

ACTIVE COMPARATOR

For 4 weeks participants will be encouraged to adopt the UK dietary guidelines (Eatwell Guide). In combination with these guidelines, an intermittent fasting regime involving two days of the week will be implemented. The regime will encourage individuals to consume of 500kcal per day for women and 625kcal per day for men, resulting in 75% daily caloric restriction during each of these two days.
