Arms Assigned Interventions
Active Comparator: Alginate based beverage Dietary Supplement: Alginate beverage
The dosage is 3x500ml daily

Detailed Description:
The study consists of a parallel RCT with 96 overweight/obese subjects enrolled into two treatment arms: placebo or active for 12 weeks. They will undergo examination at time points 0 and 12 weeks where a DXA scan will be performed to assess body composition and a fasting blood sample will be taken. At time points 0, 2, 4, 6, 8, 10 and 12 weeks their weight and waist circumference and number of test products not consumed will be recorded. In addition all subjects receive dietary counselling during the 12 weeks.
