biggest problem might be
rats from the commercial area, coming and eating your food while you snooze. Heck, just mice. Crickets. Ants.
Let's count calories:
a pack of noodles? 190.
One pound of spinach- 104 (suppose wild greens are comparable for the sake of argument)
Cup of pitted cherries 77
One medium potato 163- You get about four medium potatoes per plant, if they do well, in full sun (but you're in the woods right?)
It's a long way to 2400- 3000 calories per day. Every day.

But hey, go for it! Read up on what long trail hikers carry for food. Take Hatchet by Gary Paulsen for reading material too.
I could play in the woods too, if I didn't have anyone else worrying about me. I just wouldn't assume I could feed myself without a lot of learning and work.
