Abstract

AimTo compare the impact of 2 long‐term weight‐maintenance diets: High‐protein (HP), low‐glycaemic index (GI) and moderate‐protein (MP), moderate‐GI, combined with high‐intensity (HI) or moderate‐intensity (MI) physical activity (PA) on incidence of type‐2 diabetes (T2D) after rapid weight loss.Mate...

Primary endpoint was 3&#x2010;year incidence of T2D analysed by diet treatment. Secondary outcomes included glucose, insulin, HbA1C, and body weight.ResultsTotal number of T2D cases was 62 and cumulative incidence rate 3.1%, with no significant differences between the 2 diets, PA, or their combination. T2D incidence was similar across intervention centres, irrespective of attrition. Signficantly fewer achieved normo&#x2010;glycemia in the HP compared with the MP group (p&lt;0.0001). At 3&#x2010;years, normoglycemia was lowest in HP&#x2010;HI (11.9%) compared with the other 3 groups (20.0&#x2010;21.0%, p&lt;0.05). There were no group differences in body weight change (&#x2010;11% after 8&#x2010;weeks weight reduction; &#x2010;5% after 3&#x2009;years weight maintenance) or in other secondary outcomes.ConclusionsThree&#x2010;year incidence of T2D was much lower than predicted and did not differ between diets, PA or their combination. Maintaining the target intakes of protein and GI over 3&#x2009;years was difficult, but the overall protocol combining weight loss, healthy eating, and physical activity was successful in markedly reducing the risk of T2D.
