Intermittent energy restriction improves weight loss efficiency in obese men: the MATADOR study. - PubMed - NCBIwww.ncbi.nlm.nih.gov
Breaking up your diet 2 weeks on / 2 weeks off might be a good idea:
"[The 2 on / 2 off group] had greater FM loss (12.3±4.8 vs 8.0±4.2 kg; P<0.01) [...]."
CONCLUSIONS: Greater weight and fat loss was achieved with intermittent ER. Interrupting ER with energy balance 'rest periods' may reduce compensatory metabolic responses and, in turn, improve weight loss efficiency.
