I've gone without food for nearly a week. During that time I also had a BARE minimum amount of water.
I was about 14/15 years old and I ran away from home for (if memory serves) about 10 days. I left with Garfield strawberry gummy/fruit snacks and I stopped at a store and bought a large pack of Crackle Candy Bars and (by accident) some seltzer water *gag*. I also had a small bottle of Coke that I bought during the beginning of my trek.
This took place in Pensacola, Florida in the early part of the year (March, I think). It was freezing cold that year. Unfortunately, the home I made for myself was in a patch of woods behind a Popeyes Chicken and 2 other restaurants. When the wind blew just right, I was miserable lol
At the end of my stay, I found a small round cactus. I shaved it and ate it. It tasted a lot like kiwii.

From the ages of 18-22 or so I frequently skipped eating for days so my hubby and kids could eat (I told myself he worked and needed his strength and my kids were young and needed the nutrition).

Now, I'm an opportunistic eater. I eat like a queen at the beginning of the week (when I get my allowance) but for the last 3 days or so, I barely eat anything. But my kids still have food. I'd rather have smokes and soda and junk food to stave off hunger pains. But all in all, I'm still packing the pounds because I'm inactive. (My weight is still "perfect" according to the charts though. I want to lose 20 pounds, but I love my junk too much).

I live in a very small country town. We have 1 homeless man. MANY people are on Food Stamps and we have a couple of food banks as well. So, locally, I don't see hunger as being an issue. Junk meat and pasta/potatoes is cheaper than fruits and veggies so there's a LOT of over weight people. West Virginia (where I live) is the 3rd fattest state in the nation.
