Participants were 44 overweight and obese persons, male and female, age 18-59 years. Participants were divided into 2 groups consisting of 23 asparagus capsules and 21 placebo capsules groups. They received health screenings including history taking, mental health questionnaire, and vital signs, height and body weight, body composition, fat distribution measurements and oral glucose tolerance test. Then, a venipuncture was conducted to determine blood glucose, insulin, lipids malondialdehyde and protein carbonyl levels.

The study design was cross-sectional. Participants were 44 overweight and obese persons, male and female, age 18-59 years. Participants were divided into 2 groups consisting of 23 asparagus capsules and 21 placebo capsules groups. They received health screenings including history taking, mental health questionnaire, and vital signs, height and body weight, body composition, fat distribution measurements and oral glucose tolerance test. Then, a venipuncture was conducted to determine blood glucose, insulin, lipids malondialdehyde and protein carbonyl levels. Analysis of covariance was used to analyze parameters between groups and paired t-test was used to analyze parameters intra-group.
