It is imperative that patients are asked to monitor blood glucose levels more frequently for the first few days (at least 4 times per day – once before each meal and before going to bed). For optimum management, it is recommended that patients start the regimen on the weekend, when they can be at home and thus more attentive to the symptoms of hypoglycaemia. It is extremely important that patients diagnosed with Type 1 diabetes continue insulin treatment, no matter how low the insulin dose is, to maintain euglycaemia. For further information on the management of patients with Type 1 & Type 2 diabetes please refer to the OPTIFAST® VLCD™ Co-morbidity Guidelines.
