- VLCD

Literature review demographics and FPG in different studies. Search was performed using http://www.pubmed.gov with “VLCD” in combination with either “glucose”, “aspartame” or “fructose” as search text. The review was arbitrarily limited to articles published the last 20 years, between 1993 and 2013 and only to include full-text publications. Abstracts were reviewed in order to find results related to the aim of this study; primary outcome FPG levels after VLCD. Fasting serum glucose was treated equal to fasting plasma glucose [11]. All studies except Jackness et al. are observational regarding VLCD. Both groups in Wikstrand et al. received similar VLCD-regime. *Presented as mean (standard deviation). ^‡Presented as mean (standard error). ^#Presented as median (inter quartile range).
