I've heard the same, although it was only with one person I know. I was talking to my friend about Ramadan and how I thought it was a really healthy behavior. She laughed and told me that a lot of people eat garbage (her word, not mine - a lot of fatty and fried foods) and she had to take the initiative to eat healthier stuff during Ramadan.

Still, it definitely gives you the opportunity to reset every year.
