So we just took measurements for ourselves and it's worse than I thought. Then again maybe it isn't.

I have thighs of 74.5cm, a bum of 126.5cm, a waist of 101cm, chest of 98cm, a bust of 116.25 and a belly of 117cm.

It's helped to answer some questions for me - things like why when I sit down I see more belly than boob lately. It has also given me a far more visual picture of myself than a weight in kilos or stone. I do not know whether it will help or not but so far so good in scaring me into acting on things!

I've been thinking about loosing weight lots recently. I've had two friends lose dramatic amounts of weight just by being more careful with what they eat.

I have no intention of shrinking to Kate Moss size. For me it is sexier for a lady to have curves. As a lady who appreciates the female form I like small bums but I am far more of a fan of ladies who I can get my arms around and cuddle up close to.

My main wishes from this whole exercise are to eventually find myself at a size 14. That's two dress sizes. That's a fair few pounds. That's a whole lot less eating and drinking out. That's a whole lot less alcohol. That's a whole lot less chips.

A friend one said to me - it's pointless loosing weight for anyone other than yourself. You have to want to do it. After looking at myself in a mirror and not fitting my clothes properly I want to do it.

Ahh the oh so subtle hints. A Trinny and Susannah book. An F Plan book. Both found their way into my Christmas stocking. It doesn't matter though as my mind has already been made.

While puffing and panting on a short walk earlier I thought to myself how there has to be more to life than this. I do not want to die an early death - short, fat and stumpy. I want to be more galmorous. I want to fit my clothes. I want to have a more positive body image.

A few more days then the diet begins.

Well Christmas dinner has finished with too much of everything. Too much turkey. Too much veg. Too much coffee. Too much alcohol. I feel bloated. I feel full. I feel ultimately happy. I feel chilled.

I look forward to the next few months and a return to a new and slimmer Sian. I look forward to less of these excesses. I look forward to feeling more positive about myself.

A week to go before the new regime starts.

A week to go before I starve lol.

This blog is to document my transformation from blob to svelte slim model. Okay, well maybe not that slim but slimmer than at present anyway!

Following on from Christmas I intend to loose some weight. Whilst I have never been the thinnest of people I have never been as large as I am at present. I am finding it slightly difficult being the size I am as I am less energetic than I was, my clothes don't fit and I feel achey too.

So, the post Christmas challenge is to go from a size 18 (almost 20) to eventually a size 14. I know this will take time but I am prepared to do it.

As a greyhound fanatic it is my intention to donate £1 for every 1lb I gain or lose to Hall Green RGT in a hope to both motivate myself and do some good for charity.

I will not be following any set diet just cutting back and being more healthy. I will be endeavouring to exercise more and have less chocolate, sweets and crisps.

We will see how it goes but I will aim to record my findings in here on a daily basis - whether that will happen or not I do not know!
