Is doing a bunch of short fasts better? HELP!?!

I want to fast to lose some weight and don't honestly believe I can go for long periods of time. If say I do a five day fast then eat healthy for 3 days then do another 5 day fast will this be more beneficial then say doing something like thirty days in a row? Or should I tough it out and try doing one long fast. Which one would give me better results? Anyone??? Tweet
