20 week weight loss Challenge! (With SpreadSheet!) 8/13 to 12/31

Link to spreadsheet: Click here

Hello!
There are 20 weeks left in the year and I am ready to get back on the weight loss wagon.
I am here to propose a challenge, a 20 week weight loss and accountability Challenge.
I have created a spreadsheet anyone can access to log their weight for the next 20 weeks and set up goals along the way!

*Starting picture to be taken on the 13th is reccommended but not required.*
Weigh-in dates are listed below
8/13
8/20
8/27
9/3
9/10
9/17
9/24
10/1
10/8
10/15
10/22
10/29
11/5
11/12
11/19
11/26
12/3
12/10
12/17
12/24
12/31

Each week, I will go through the list and find the "biggest loser" (by percentage of course) so that each week we can celebrate everyone's losses.

I hope people decide to join! Good luck!
