6. Okay, so we are not going to pretend like you are not going to enjoy greasy food while being on vacation. Its normal to behave like that! You are finally feeling relaxed and you want to eat whatever you want. Also, local cuisine is very tempting, and we understand that too. But you can solve this problem by eating badly only once a day. You are feeling particularly hungry in the morning? No problem, eat whatever you want for breakfast, and then eat healthy for lunch and dinner.
