Is water fasting/starving better to get to a lower body fat percentage than working out?

It's definitely requires lower effort if you ask me. I fast for three days, eat normal after that for one day and repeat the cycle. Should I keep doing this until I am at a low body fat percentage or just go the gym instead?

I dislike going to the gym and kinda want to start boxing but perhaps the gym is better for getting muscular. Being able to fight would be useful and more fun though I suppose.
