  Purpose
Epidemiological studies have indicated a positive health impact of coffee. Nevertheless, intervention studies testing the effect of daily coffee consumption over a longer period are lacking so far. Moreover, there is a lack of knowledge about the properties of different coffees and their influence on weight development. Therefore, we tested the effect of two coffees differing in their alkyl pyridine content over a period of 3 months on weight development.

Condition Intervention
Overweight Dietary Supplement: test coffee Dietary Supplement: control coffee

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Health Effects of Coffee Consumption
