8 Week Challenge!

Okay, so a friend of mine posts an open invite to anyone who would like to join her for an 8 week weight loss challenge. She found an interesting points/reward system from a blog called the sixsisters. Their site even gives you free downloads of journals to keep track of your food choices and points. I decided to join her along with five other women and we start tomorrow.
This is basically how it goes:

"This is an 8-Week Challenge that starts on a Monday (you pick what Monday to start on)
-Decide an amount that each person pays to enter the challenge (we did $25 a person)
-There is a weekly point calendar for each of the 8 weeks. You earn points by eating healthy, exercising, drinking water, etc... It's not just for weight loss!
-Beginning on Week #2 there is a double point challenge (highlighted in yellow)
-You can exercise each day, but you will only receive points for exercising 5 days a week.
-You can choose to not each sugar/treats each day, but you will only receive points for not eating sugar on 6 days (everyone needs a free day!).
-There is a sample food journal that you can use or you can use your own kind of food journal to keep track of what you eat.
-Weight yourself anytime each Sunday and tally up all points by 9 PM. Make sure that you weight yourself under the same circumstances each week (for example: Morning/Night, Empty/Full stomach)
-Choose someone in your challenge who will be the one you send a weekly email/text to with your totally weekly points and totally weight loss points for the week. They will have to keep track of everyone’s points and then have them send out an email or text with everyone’s standings on Mondays. We said that all points had to be emailed/texted by midnight on Sunday. If you didn’t send an email/text by that time, you received no points for that week. So each week you will send in 3 numbers: Your weekly points, you weight lost for the week, and your total points for that week.
-Daily contact with teammate: It’s amazing the strength that comes from encouragement from your teammates! We decided as a team that you could email, call, or text someone on your team to encourage them to have a healthy day. It helps knowing that you are all in this together and makes you accountable for what you do or don’t do.
-Example of weight loss points: You will get 5 points for maintaining your lowest previous weight AND 10 points for each whole pound. For instance, if you gained weight, you will report 0 points AND you don’t get any weight loss OR maintenance points in future weeks until you return to the lowest weight you had already achieved. If you maintained your previous lowest weight, you report 5 points. If you lost 1 pound, you would get 5 points for maintaining plus 10 points for that pound, so you would report 15 points.
-Cash prize money will given to the person who has the most total weekly points.

So here goes everything!
