Abstract

Management of type 2 diabetes has now been simplified by the understanding that the condition is caused by excess fat in the liver together with suppression of beta cell function by the associated excess liver export of fat. These factors can be reversed by substantial weight loss leading to remission in the early years after diagnosis, or at least major decrease in cardiovascular risks and improvement in glucose control for all. Weight loss by any means is successful, but it is most easily achieved by rapid action using a low or very low calorie diet of around 800 kcal/day followed by sustained modest restraint of dietary habits. Oral hypoglycaemic agents and one antihypertensive drug can be withdrawn on day 1 of the weight loss diet, raising the importance of appropriate deprescribing.
