Hi there!
I would not worry
WW says in their materials that after 3 weeks on the plan, you should be losing a max of 1% of your current body weight a week, or 2 pounds. If people weigh more than 200 pounds, than the 1% can be bigger
The first 3 weeks are a "settling-in" period, and you are going to lose
quite a lot of water weight.
Your 1st week, you lost 2.4 or about 1%. Your 2nd week, you say you will probably lose 7 pounds, but this is after getting over your TOM.
My guess would be that you have lost 2 pounds of fat PLUS 5 pounds of water retention from your period. (Speaking for myself, I always lose about 5 pounds of water after TOM.)
If you find, after Week 3, that you losing more than 1% of your body weight per week, I would say to:
* Definitely stick to eating all your Daily Points, plus...
* Eat all your Flex Points too... plus, if needed...
* Eat all your Activity Points
This is my first week back on WW (was on it 1999-2001.) I am probably going to lose anywhere from 5-6 pounds this first week (not my TOM either.) I am eating my Daily Points plus the Flex and Activity Points. I would not panic if I were you... but if you need to slow it down, try the above
