Will I be able to do this again?

When I was 21 I went 4 days without food before feeling a little hungry. It took 4 days without food for me before I began to feel hungry. I lost 10 pounds and never gained the weight back. Or at least it took about 6 years for me to gain the weight back. I want to try this again because I don't have a gym membership and I figure if I can go another 4 days without food I can lose another 10 pounds.
Will I be able to do this again?
