It only takes a few days in the high mountains to feel as lively as a poultry raised in the great outdoors. With 150 grams of cheese, the same amount of cold meats, 300 grams of potatoes and two glasses of dry white wine, the bill will come to around 1600 calories.

The trap lies in gluttony and conviviality, as well as in alcoholic drinks, which do not have a satiating effect. In short, no more raclette – in moderation, then – and no more Roussette de Savoie.
