Effect of Bitter Melon Seed Oil on Body Weight

Status Completed

Clinical Trial Summary

To investigate the metabolic benefits of bitter melon seed oil (BMSO), overweight or obese healthy Taiwanese adults (n=60) were randomly assigned to receive capsules containing either olive oil (OO; placebo) or BMSO at 4.5 g/d dose for 12 week. Across intervention period, body weight, BMI, waist-to-hip ratio, and body fat mass were measured. Blood were collected before and after intervention for measurements of blood lipid and inflammatory cytokines. The anti-obesity effect of BMSO was further assessed by stratification of participants according to UCP1 rs1800592 polymorphism.

Clinical Trial Description

Bitter melon is a common Asian vegetable. Its seed is not edible and discarded as a waste product. However, the seed oil is enriched in cis9, trans11, trans13-conjugated linolenic acid or alpha-eleostearic acid (alpha-ESA). Investigators previously demonstrated the anti-obesity functions of bitter melon seed oil (BMSO) in animal trials. Herein, a RCT was conducted to test the potential of BMSO in developing as a functional culinary oil for weight control.

Considering UCP-1 played a pivotal role in anti-adiposity function of BMSO as demonstrated in animal studies, the anti-obesity effect of BMSO was further assessed according to UCP1 rs1800592 polymorphism.

Healthy Taiwanese adults with overweight or obesity were recruited by advertisement and were assessed by a family medicine physician for eligibility. All participants signed the consent form. Blocked randomization was used to randomly assign participants into one of two groups to receive indicated supplement (BMSO or OO capsules with identical appearance; 4.5 g oil/d) for 12 week. Subjects were requested to maintain their usual diet and physical activity during the study period (0-12 week).

Anthropometric measurements were done on week 0, 4, 8 and 12. Three-day food records, collection of blood samples and physical health check were conducted on week 0, 4 and 12. Indirect calorimetry was done on week 0 and 12. Questionnaires about self-reported side effects, such as trouble sleeping, constipation, diarrhea, increased heartbeat, palpitations, headache, anxiety, or dizziness, were collected in each visit. Group allocation was concealed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
