• IQP-AE-103 (330mg) (Dietary supplement): High dose capsules
• IQP-AE-103 (165mg) (Dietary supplement): Low dose capsules
• Placebo (Dietary supplement): Placebo identical to verum capsules

Primary outcomes

• Mean change in body weight (kg) [12 weeks]: Difference in mean change of body weight (kg) between the higher dosed verum (1980 mg a day) and placebo group after 12 weeks of intervention in comparison to baseline.

Secondary outcomes

• Mean change in body weight (kg) [2, 4, 8, 12 weeks]: Changes in body weight (kg) after 2, 4, 8, and 12 weeks of intervention, each in comparison to baseline, between the two active and placebo group
• Mean change in body weight (%) [2, 4, 8, 12 weeks]: Changes in body weight (%) after 2, 4, 8, and 12 weeks of intervention, each in comparison to baseline, between the two active and placebo group
• Proportion of subject weight loss [2, 4, 8, 12 weeks]: Proportion of subjects who lost at least 3% and 5% of baseline body weight after 2, 4, 8, and 12 weeks intervention, each in comparison to baseline
• Change in waist circumference (cm) [2, 4, 8, 12 weeks]: Changes in waist circumference after 2, 4, 8, and 12 weeks intervention, each in comparison to baseline
• Change in hip circumference (cm) [2, 4, 8, 12 weeks]: Changes in hip circumference after 2, 4, 8, and 12 weeks intervention, each in comparison to baseline

Other outcomes

• Safety parameters (lab parameters, vital signs) [12 weeks]: Change in safety lab parameters, vital signs
