My leader says we have a tendency to underestimate the points of our food and overestimate the activity points we earn. I really try to be honest with myself, if I try and get away with skimping on the points, I'm the one who's going to suffer.
I think it's better to mark it down, even if you go over all your points for the week, you're better off keeping track, rather than giving up because you're over, I've lost weight many weeks where I tracked and went over my allotted points for that week. Maybe it was because of overestimating, who knows..
anyway, moderation is key, make sure you eat enough, I don't usually have that problem either
best to all
