i tried sticking to a balance diet and i did lose about 20 lbs, but after that i just got tired of it and gain it all back and more.
Well ... hm.

The thing is you have to make the commitment to be healthy and eat right.
This is something that I post here a lot - I'm sure people get tired of hearing me say it. But it really is at the heart of my philosophy about healthy eating.
There are things that we all do in life that we don't necessarily want to do all the time or that we get tired of. I'm tired of getting up at 6:30 every morning to go to work. Trust me, I'd much rather sleep in and get up around 10 a.m. But "getting tired" of going to work and jsut not doing it any more isn't an option. Not if I want to pay my bills.
I get tired of doing laundry, but deciding to just not do it any more isn't an option. Not unless I want to wear dirty, smelly clothes to work.
I get tired of paying my bills. Trust me, I could find MUCH more fun and interesting stuff to do with my money. But I like having a roof over my head and electricity and running water.
For me working out and eating healthy is that same kind of thing. Sure I get tired of it. There are days that I dont' want to go to the gym. There are days that I get home and think "god, it would be so much easier ot just order pizza". There are days that it's all just too much. But I do it anyway. Just like I get up in the morning when the alarm goes off and I do my laundry (3 loads last night - ick) and I pay my bills each month.
I've decided that being healthy is as important to me as having a job, paying my bills, and living a reasonably clean life. So I am committed to it.
Only you can make that commitment. If you choose not to, then you have ot live with the consequences.
