    Long-term weight-loss maintenance: a meta-analysis of US studies
    James W Anderson, Elizabeth C Konz, Robert C Frederich, and Constance L Wood
    http://www.ajcn.org/content/74/5/579.full

    Concluded that " Successful very-low-energy diets (VLEDs) were associated with significantly greater weight-loss maintenance than were successful hypoenergetic balanced diets (HBDs) at all years of follow-up. "

    "Most investigators used VLEDs of <800 kcal/d (3347 kJ/d) or HBDs during the weight-loss phase." HBD is a moderate calorie deficit, usually through counselling / behaviour therapy.

    http://archinte.jamanetwork.com/article.aspx?articleid=623599 concluded that "The overall weight change from pretreatment to the 5-year follow-up was greater in the VLED+BT group than in the BT group (-16.9 kg vs -4.9 kg, respectively; P=.03). Men succeeded better in the VLED+BT group than in BT. Among the dropouts, the mean weight change from baseline was +5.2 kg in the VLED+BT group and +13.0 kg in the BT group." (BT = behavioral therapy).

    So very low calorie interventions do yield a better long term weight loss, not least because they achieve a bigger weight loss to start with.
