I keep wanting a teacake. :-)
By the end of this you'll be having the crackers with cheese...
@lugeforlife I've been having a bit of a think about your post, before replying.
I think I'm older than you but were probably in a similar place when I was younger. So in my late 30s, I was a size 20-24 and very unfit, couldn't move well, etc. I got really fit, lost 14kg, etc. Cleaned up my diet with IF, then paleo, the whole kit & caboodle. The through my 40's gradually gained all the weight back (tho interestingly, I'm now a 14/16/18, not entirely sure, so much more compact) and not as fit but still better off than I was, can move better.
I have got very shirty with people saying things like that thread over the years, including online groups, GPs and dudes down the gym.
However, I now know I eat better than the majority of them (same diet as DH, who is 70kg @ 6ft), my bone health is probably better & my muscle mass is sufficient. I'm managing a load of autoimmune stuff, the ND issues and the stress about things/people in my life but beyond my control...
Best to stay away from those threads, as MN is notorious for competitive undereating & fat shaming. And one thing I did learn off my PT course is that people do not understand the risks of continuous undereating on bone and brain health. Seriously, better to be a bit fat, statistically the best place to be!
The other thing is shame and the pervasive & destructive nature of it. Brene Brown is a good read/watch on this. I would never have thought that I suffered from shame but I do and it's apparent in food (never ate in front of people from when I was a kid, as I knew I'd get judged) and the state of my house (don't let people come visit...that's still a work in progress.)
Your goals are excellent. Manageable, realistic, pragmatic and fit in with your life and how you want to live it. Add in a bit of resistance training (weights/bodyweight/pilates) and you'll get more solid and protect your muscles and joints, bit of walking (heart, bones and fluid movement) and you're golden!
I will say tho that regardless of the progress above, I'm better with outside help. It doesn't have to be particularly onerous, just a bit of coaching or a course, just to keep me on track.
The other thing is keep on top of menopause/thyroid/arthritis issues. Do not ignore slowing down,being abnormally tired or feeling cold or anything where you say "it's just my age!".
