Abstract

Background and objectives

Orlistat which is taken by obese patients may present some therapeutic assistance through its inhibition of lipase activity. Otherwise, a natural lipase inhibitor as cinnamon is widely used traditional medicine to decrease cholesterol and body weight. The current study aimed to investigate the weight management of orlistat in comparison with cinnamon through different obesity related targets.

Methods

Subjects were divided into: Group 1: subjects received cinnamon capsules for 60 days. Group 2: subjects were received orlistat twice daily for 30 days, then once daily for another 30 days. Blood samples were collected at baseline and after 2 months.

Results

Both orlistat and cinnamon groups showed a significant reduction in BMI, lipid profile, and lipase activity compared with baseline. Orlistat group showed significant elevation (p < 0.001) in glucagon, insulin-degrading enzyme (IDE) and dopamine level concomitant with the decrease of serum glutamate compared with baseline level of the same group and cinnamon group. However, cinnamon reduced serum insulin level and insulin resistance (IR) compared with baseline level of the same group and orlistat group.

Conclusions

Orlistat can be used in weight management not only for its pancreatic lipase inhibition but also, due to its indirect appetite reduction effect through elevated glucagon, IDE and dopamine levels and its inhibitory effect on glutamate neurotransmitter, whereas, cinnamon improves BMI and glycaemic targets.
