I keep hearing different things from different posters about this. I figure if I've earned the points, I'm darn well gonna eat them if I'm hungry
According to the week 3 book (the one on exercise) the policy is somewhat ambiguous. Page 12 says
all activity points count toward your weekly activity goal. Then you decide - Swap activity points values for food or don't swap to help boost weight loss. Page 14 says limit the points value to no more than an average of 4 per day.
However, the part on page 14 is emphasizing not to overdo it, not to exercise more just to be able to eat more. It also says if you are ready to earn more, consult a trainer, etc.
Nowhere do I see that it says you can't eat every point that you earn. Most of the time I eat fewer than I've earned. Although there are days I wish I had more
I guess this is like most everything else, try it one way for a few weeks and see how it's working for you. If you're not happy with the results, change things up and see if that works.
