Overweight and obesity are leading health problems. The study investigates the effect of a food ingredient from two different sources at two different doses on food intake and appetite markers over a 10 hour period. All participants reported to the laboratory first thing in the morning and remained in the laboratory until after their evening meal. A fixed breakfast was served but the participants were free to eat as much as they liked at lunch and dinner. Blood was taken at regular intervals during the day and assayed for glucose and several hormones related to appetite. Subjective measures of appetite were also collected over the 10 hour test session.
