Body composition may be a better predictor of risk for cardiovascular complications compared to weight loss per se in T2DM. In this study we saw a significant decrease in total weight, %FM and significant increases in %LBM over time with no significant difference between diets. This is in contrast to results reported in a recent meta-analysis [30] of 24 short term RCTs comparing an energy restricted SPD to an energy restricted HPD which showed greater reduction in weight and FM together with a lower reduc- tion in FFM resulting in decreased triglycerides and sus- tained resting energy metabolism. It could be speculated that the length of the study would have an effect and that longer duration would show declining effect with declining compliance. However the meta analysis showed no difference between studies of 12weeks however only one study in the meta analysis was long term (52 weeks) and was excluded from the analysis due to lack of data.
