Movement comes with appetite

07. Zurich - ETH Zürich - . A body that is provided with food too often gets caught up in the maelstrom of a lack of exercise, obesity and ultimately diabetes. The trigger is a molecular switch that is controlled by insulin, a new study by scientists from ETH Zurich has revealed. Eat breakfast like a king, lunch like a prince and dinner like a pauper. And nothing in between: no snacks, no sweets, not even anything we think of as healthy. For in order to stay healthy the body needs to fast between meals.
