If you check out their analyses...all they looked at were weighted means. WTF! They don't even rationalize why they are ignoring effect size, except for implying/saying that it was easier to look at means.  We note, however, that the number of studies that had long-term follow-up measurements was surprisingly low given the large number of published dieting interventions.  Maybe that's because they only looked through reference lists of studies on Google Scholar and PubMed to find their sources!! Hahahahaha!! Wow, even research hams have a laziness that shows through in their work - or lack thereof!
