I do have a scale that also measures body fat, water and bone percentages and I don't generally mention those numbers, but it's interesting to note my percent body fat went from 45.8 at the start of my weight loss to 40.1 today, while water percentage was 39.5 at the start and 43.7 today. As I lose fat it stands to reason water would make up a larger percentage of my total weight. But the one I worry about is bone ... that went from 6.9% to 6.2%. That may not sound like a lot but it means I was 8.99 kg (19.82 lb) bone at the start and 6.06 kg (13.33 lb) now. I have read you can lose bone when losing weight and it concerns me at my age. I'm considering adding a daily women's multi-vitamin to help ensure I get enough nutrients including calcium. I think getting nutrients from your foods is always best, and the vitamins and minerals in pill form are not always easily used by our bodies but as I'll be on a reducing diet for at least another six months, it might be a good idea.
Unfortunately my scale doesn't give percentage of muscle, but I have definitely been doing a lot of weight-bearing exercise lately. This past week I exercised 6 out of 7 days and 3 of those included jogging intervals. Two were half hour walks and one was a 6K brisk walk that took us about an hour and ten minutes. With that and plenty of protein in my diet, hopefully I'm building muscle.
I got my 1901 Singer treadle sewing machine up and running yesterday ... now I just need to get some practice in before I attempt to take in some of the slacks that are just too big now. As I said, I'm no seamstress but I'll give it a go. Wish me luck!
