I've posted about this somewhere else recently, but I can't remember where, so please forgive me for repeating myself.
I'm only weighing myself once every four weeks because after years of dieting I know that I find slow patches or set-backs incredibly demoralising and obsession-inducing, making dieting harder and sometimes causing me to give up completely.
I have committed to doing the Exante Total Solution for 28 days, come hell or high water, so it doesn't really matter what interim weight losses or fluctuations happen before then, because I will still be following the diet. Good, bad or indifferent, I can't influence the results beyond following the plan to the letter. And I have promised myself to do that anyway. So I don't really gain anything by checking my weight in the meantime, other than satisfying my curiosity. Yes, I'll be pleased if it is going well, but I'll be devastated if it isn't. On balance, I'd rather not know, and just wait for the surprise at the end.
So I'm saving my weigh-in for Day 26, in time to re-order from Exante if I want to continue for another month on the same basis. (This will be exactly four weeks after my first weigh-in, which I dashed off to do when they asked me my weight during the checkout process when I was buying my first month's food packs.)
