I've been pondering this today thinking about my body and weight at 18 compared to now at 47. I'm 5ft 3in and was then too.
I always weighed clothed back then and on clinical scales and was around 8st 3lb at my lightest and 9st at my heaviest. The contraceptive pill had a big impact on my weight then and I went down to the 8st 3lb after coming off it.
I'm now 8st 11lb and hoping to lose some more and tone up. I've had 3dc and am wobbly.
My highest weight not pregnant was 10st 10lb after lockdown. My highest weight 8.5 months pregnant was 11st 2lb. I gained a stone in each pregnancy. Lowest weight not pregnant since 18 has been 8 st 3lb last summer. I felt amazing at that weight! Although still wobbly.
Does your weight fluctuate over time or are you steady like my mum who is the same as when I was born?
