Abstract

Purpose

This study aims to examine the effect of lesser yam-based cookies on glucagon-like peptide-1 (GLP-1), blood glucose and lipid profile in overweight and obese individuals.

Design/methodology/approach

This was an experimental study on overweight or obese adults aged 21-50 years old. The intervention was done by giving 87g of cookies made with lesser yam flour in combination with wheat flour (80 and 20 per cent, respectively) for six weeks. Anthropometric measures, fasting plasma glucose, lipid and GLP-1 were measured before and after the intervention.

Findings

There were no changes in anthropometric measurements and glucose level after the intervention (p > 0.05). However, plasma low density lipoprotein (LDL) and total cholesterol decreased after the intervention (p = 0.033 and p = 0.035, respectively). Although fasting GLP-1 level (p = 0.121) was unchanged, we found that the slight changes in GLP-1 concentration was associated with changes in LDL and total cholesterol (p = 0.002 and p = 0.001, respectively).

Originality/value

The lesser yam-based cookies reduced fasting plasma LDL and total cholesterol, but not glucose level after six weeks of intervention. Additionally, reduction of LDL and total cholesterol level was negatively associated with the changes in GLP-1 level.
