Prediabetes may be managed with diet, sleep and support.

Experts and research cited here note that dietary approaches, including the Mediterranean diet and structured behavioral programs, are associated with reduced progression to type 2 diabetes, and that shorter or poorer-quality sleep is linked to higher prediabetes risk.

Prediabetes describes blood sugar levels that are higher than normal but below the threshold for type 2 diabetes. Health organizations and recent reviews bring together evidence on diet, behavior programs, sleep, and peer support as ways to address progression. The American Diabetes Association provides resources on meal composition and related topics, and research has examined dietary patterns such as the Mediterranean diet. Reviews and studies from the National Institutes of Health and medical journals point to links between sleep quality and prediabetes risk and to the effects of behavioral programs. Key points: - The American Diabetes Association provides materials on plate composition, the glycemic index, protein foods, and cites research on the Mediterranean diet and reduced incidence of type 2 diabetes. - The National Institutes of Health reports an association between sleep duration and quality and the risk of prediabetes, and has published a review on prediabetes diagnosis and treatment. - Harvard Health offers practical guidance on improving sleep that is widely referenced alongside clinical reviews. - A systematic review in the Annals of Internal Medicine examined behavioral programs for type 2 diabetes, and the Defeat Diabetes Foundation highlights peer support and self-empowerment resources. Summary: These sources collectively describe several evidence-informed approaches being discussed for people with or at risk of prediabetes, including dietary patterns, behavioral programs, sleep improvement, and peer support.
