This master thesis shows that how to make a transition in everyday life and how to amplify the transition to the system level. Specifically, this research takes a practical case about 'protein transition' in the Netherlands. Based on Transition Design, practical theory, and thing-centric approaches, it designs a new framework for the change of eating habit. For instance, the study explores how different practices and values converge in the ‘kitchen’. Then, it demonstrates opportunities for ‘protein transition’ around the new 'kitchen' concept.
