As series of studies have shown over the past few years the mechanism that causes type 2 diabetes. Recent evidence shows that this mechanism can be reversed back to normal functioning through the restriction of food intake and a weight loss of around 15kg on average. This article summarises new understandings of type 2 diabetes and explores changes to food intake that can help achieve the necessary weight loss for remission and maintenance of normal haemoglobin A1C concentrations.
- The interpretation of remission requires special attention as sometimes the word ‘remission’ is used to describe the state of meeting glycaemic targets even when the hypoglycaemic drugs are being administered
- Different people have different threshold, which explains why only 50% of those with type 2 diabetes are obese
- Avoiding weight regain can be achieved through different dietary interventions, based on an individual’s preferences.The inclusion of physical activity also supports weight loss and maintenance
- RCT show caloric restriction, low carbohydrates diets, and intermittent fasting effective for weight loss, given adherence.
- Factors that affect food intake include age, sex, genetics, percentage of body fat, family and sociocultural factors, in addition to food availability and accessibility, cost, and food advertising and promotion
- Policy interventions are needed to support healthy dietary intakes in populations. These include but are not limited to education, clear dietary guidelines and food labelling, taxation on high caloric foods, and guidance on food portions
