Conclusion
This study shows that weight loss is the driving force in
the improvement in metabolic control in this group of
participants with type 2 diabetes. Overall the HPD had a
beneficial effect on metabolic control comparable to the
benefits achieved with the SPD in this weight loss study
with no adverse effects demonstrated. Whilst the metabolic
improvements were modest further research could
focus on less well controlled subjects where weight loss
and dietary interventions may show a greater benefit.
