Yes, I would definitely measure yourself. I took loads of measurements all over my body the morning before I went in for my op. 3 weeks post-op & I was a bit disappointed at how slowly the weight seemed to be coming off when I was eating so little, I was losing it faster on the pre-op diet! So I decided to redo all my measurements.
I had lost an inch and a half from round my neck, an inch from the tops of my arms, an inch from my waist, 2 inches from my hips, an inch from my thighs, and even half an inch from my calves!!! And that was in just 3 weeks!!!
It definitely made me feel a lot better & I stopped worrying about what the scales said - although yes, I do still weigh myself every morning, lol.
