eeek... I'm not medically trained but I believe the 500cals or so a day are needed for your body to basically function. I think it would be harmful not for you to eat all 4... I know it seems stupid because there's no hunger and I end up having 2 or 3 left at night but you should force yourself to have all of them.
I'm sure i remember reading somewhere too that if you don't get enough cals/vitamins etc., your body will burn the muscle tissue rather than the fat for energy!
I'm not sure if it's ok to skip the occasional foodpack on the total plan because each pack has been worked out to provide nutrients and vitamins.
I'm on the lite plan and had to miss out packs in my first week because of the meat flavours such as chili con carne but when I asked about this out at my group meeting we were told we must eat all of our 3 packs.
I suppose if you missed one or two a week you won't do any harm but if you regularly miss a pack then in the long term you won't be getting the benefit of the vitamins which could cause health problems.
As a woman it is very beneficial to get the b vits and stuff like magnesium and iron.
My LLC has been very adamant that we must make every attempt to eat all 4 foodpacks a day, for 2 reasons:
1. You don't get 100% of your daily nutrients if you don't
2. You actually lose LESS weight by eating less than the 4 foodpacks. Reason being that if you eat 4, you've got the minimum requirements that your body needs to function. But if you eat only 3, your body goes into starvation mode and actually tries to retain as much as it can (i.e. your excess fat) instead of burning it up for energy.
So really, don't skip foodpacks.

EAT ALL YOUR PACKS! I was on packs for almost nine months and can safely say that in the weeks I didn't have them all I lost less weight. Yes, it sounds bizarre that you need to eat more to lose more but it's true. There was even one week when I put on 1lb because I was stupidly working on the theory that the less I had, the more I'd lose. Can you imagine how disheartened I was thast week?
You might feel fine but the long term effects of actualt starvation are not worth risking.
Some days I'd 'double up' and have two at a time. Make them lovely and thick.
They tell you to have four for a reason. Because that's what works! If you want to lose your weight quickly, have them all!! x
