Jillysmom: You say that you usually don't get in all of your points---by this, do you mean that you do not reach your minimum level? If so, then your body might have entered its self-protective mode, whereby metabolism slows in response to perceived "starvation." If you're exercising regularly, you need to get those points in----and may even need to exceed your point range by using earned exercise points.
Kelly's right---you need to make sure you get at least a couple points' worth of "good" fat in each day. This is one of the easiest ways to boost point intake without overstuffing. Personally, I steer clear of margarine, because its trans-fatty acids scare me more than the animal fat in butter (which I only rarely use). Instead, I use olive oil in my salad dressing, toss a handful of almonds into things here and there, add flax seed to my oatmeal, use peanut butter, etc. I know that my diet does not provide all of the essential fatty acids I need, so I also supplement my intake with GLA (the essential fatty acid in evening primrose oil---great for PMS).
Another thing you might want to consider is the way you are distributing your points across the food groups. The Week 4 (I think) booklet contains a questionnaire that helps you determine whether your satisfied with a diet higher in carbs, higher in protein, or one that is balanced. For each of these approaches, there is a suggested distribution of points. I know that I do not do well with many refined carbs--following the higher-protein plan (which isn't high-pro, low-carb like Atkins by any stretch of the imagination) has made a tremendous difference for me, both in terms of how I feel and how I lose. If you don't have the info, feel free to email me (
[email protected]) and I'll be happy to pass them on to you.

I also have journals for each of the three approaches--makes it easy to just check off boxes to make sure you get in all of the good things your body needs to run efficiently.
