Welcome to the forums. 3FC is very motivating. When i'm at work I can't wait to come home and get on the forums because the support and encouragement is wonderful.
Last week I was 240lbs but I managed to lose 5 pounds so far by eating less, eating healthy, drinking lots of water, and getting the support I need on the forums.
I believe you can do it. Every time temptation hits me I just tell myself
"i will not let food control me. it isn't worth it. i can do this."
It's your temple and it's only up to you to design it how you want.
You should start off with a small goal first and once it's completed tell yourself
"I have already accomplished this amount of days, Why start over?"
Keep going!
Another thing, Always listen to music that will keep your body moving.
It's much more motivating and it's a good workout.
Good luck with your goal. If you need a support buddy, you've got one right here.
