Summary

The regulatory effects of the peanut skin extract (Sugarlock®) on body fat and blood glucose was demonstrated in a double-blind, placebo-controlled study. .

Detailed description

Peanut skins, a by-product of peanut processing industry, is usually discarded as a waste in despite of the high content of phenolic compounds. Polyphenol extract from peanut skins has been demonstrated to inhibit α-amylase activity in vitro. Hence, the aim of this study was to evaluate the regulatory effects of the peanut skin extract on blood glucose and body fat by a double-blind, placebo-controlled, clinical study. Subjects with simple obesity (body mass index \[BMI\] ≥ 27 or body fat ≥ 30%) ingested 4 Sugarlock® (n = 16) capsules or placebo (n = 14) a day for a total of 6 weeks. Anthropometric measurements (body weight, body fat, blood pressure) and blood biochemical markers including fasting blood glucose (FBG), albumin, total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, creatinine (Cr), blood urea nitrogen (BUN), AST, ALT were examined every three weeks. Also, 5 subjects were randomly selected for MRI scans to examine the distribution and thickness of abdominal fat layers before and after the trial.

Type	Name	Description
DIETARY_SUPPLEMENT	Sugarlock®	Subjects ingested 2 capsules (Experimental group) in the morning and 2 capsules in the evening (4 capsules/d) for a total of 6 weeks. Anthropometric measurements such as body weight, body fat, waistline, hipline, blood pressure (systolic blood pressure \[SBP\] and diastolic blood pressure \[DBP\]) and blood biochemical parameters including FBG, albumin, TC, TG, HDL-C, LDL-C, Cr, BUN, AST and ALT were measured every three weeks. Five subjects were randomly selected to take MRI abdominal scans before and after the trial. After 6-week consumption, anthropometric measurements were examined on week 8 for a follow-up observation.
