How would fasting once a week affect me?

I feel like I'm constantly stuffing my face. Whenever I'm not actually eating a meal, I'm sucking on hard candy, chewing on a tooth pick or grabbing snacks. I've been told I have an oral fixation lol ;)

Needless to say, I'm overweight and I want to fix that, but I also want to address my cravings.

I do exercise-- in fact, if I wasn't so active I'd REALLY be in trouble...

In addition to changing the way I eat and what I eat, I'm thinking about fasting.

Some people have told me that fasting can help break the constant craving for food all the time. I also think I'd just like to feel really empty for once and give my body a break from the constant cycle of eating. I've also heard that fasting is more "natural" for your body, since humans haven't had such a huge amount of food available 24/7 until really recently in history.

So, how would fasting affect me? I'm thinking 1 day each week-- is that realistic or effective?

Would it ACTUALLY reduce my food cravings over time?

Is it possibly dangerous for your health, or good for you?
