How crucial is it to follow the maintenance diet?

Maintenance 1 is just as critical as the VLCD. It is during the 21 days of M1 that your new weight set point is established and your hypothalamus is reset. The entire six weeks of maintenance is part of the treatment – don’t stop until you’re finished! You don’t want all your hard work in VLCD to go to waste…and it will if you don’t follow the Maintenance plan.
