Enjoy food and eat slowly is a line I saw on an Italian menu board. I have enjoyed a variety of delicious Italian food on my holiday in Tuscany. I am managing to stay in shape by exercising and choosing to truly enjoy food. I look for a level of enthusiasm I feel in the foods I eat. If I am not really enthused, I choose other foods to eat. For example, I am no fan of bread dipped in olive oil, so I skip bread most of the time here in Italy. I love pasta, so I enjoy that regularly. A daily dose of a small gelato is great. The cheese is awesome! I love desserts too.
So I believe the making life good secret to staying in shape while on holiday is to exercise and enjoy foods you love, plus eat green veggies daily.
