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
