A 1995 meta analysis found that studies supporting HCG for weight loss were of poor methodological quality and concluded that "there is no scientific evidence that HCG is effective in the treatment of obesity; it does not bring about weight-loss or fat-redistribution, nor does it reduce hunger or induce a feeling of well-being".
Unha metaanálise encontrou que os estudos que apoian que a hCG é un axente redutor de peso eran de mala calidad metodolóxica e concluiu que "non hai evidencia científica de que a hCG sexa eficaz no tratamento da obesidade; non fai perder peso nin redistribúe a graxa, nin tampouco reduce a fame ou induce unha sensación de benestar".
