My gym membership may be a little bit pricey, but a)it gives me an incentive to get out the house b)it has huge health benefits. I pay a monthly fee and have unlimited use of gym, sauna/steamroom, sports activities, aerobics etc. Too many benefits to choose from.
I think anything that involves making you physically and emotionally healthier is worth it.
As for all that other stuff, I cut down on my cable a little bit because I don't watch as much TV nowadays as most stuff is net based anyway.
Food, I've relapsed this week because I was too lazy to cook, but I'm gonna shape up on that come next week.
Electricity bills aren't high and expecially now that its summer I don't turn the lights until after 8pm and don't use the heating and England doesn't get hot off enough on a consistent basis where you need AC.
Other than that, I trust try and keep everything to a minimum and save up as much as possible.
