A note from Martin: Sarah has insisted on taking over the column this week so she can bleat on about her favourite topic - herself.
Yes, it's true, I'm taking over the column but I'm not talking about my favourite topic ... that would be chocolate. This is like the anti-chocolate topic: fat loss.
Three months ago, I decided to enter a fat-loss challenge through a fitness group in Hawke's Bay called Extreme Fitness.
Embarrassment was the main emotion felt when I went for my first weigh-in. I wasn't so ashamed about my weight (I've been seeing the same number on the scales for a few years now) but more the expanse of tape needed to measure around my waist and hips, and just how far those dreaded calipers had to stretch.
I almost cried but like the trainer told me: "It can only get better from here."
