I had always been slim due to exercise.
However it was a shock that once I hit tbe menopause I went up to a size 18.
I am back down to 12.
What worked was less cardio, although I still do some cardio for stamina, and ifting heavy ( for me)weights. I do a full body routine 4 x a week.
Just a word of warning though, I have always loved doing Romanian Deadlifts but have been strongly advised to stop due to vaginal prolapse. Even if you haven't had a prolapse yet, RDLs aren't your friend as you get older.
I also spend time doing flexibility and functional moves daily. Nothing massive, maybe 10 mins in the morning as part of my get ready routine. I wish I did this years ago, it really makes a difference to how I feel.
Diet wise I have more or less stopped drinking alcohol and sodas. I never have orange, pineapple or any other juice unless im on holiday.
I have found it difficult to give up chocolate bars( I love Picnic bars!) so still have them but only occasionally.
I know it's a controversial topic but I have given up UPF as much as I can ( except Picnic bars!!!) It has made me think about what I'm eating and has definitely made a difference.
The other things that have helped is drinking more water, especially at work. There's a big tea/ coffee/ chocolate culture going on there but I've got into the habit of asking for a glass of water. It's not always fun of course.
All these things meant lifestyle change which isn't always easy but once you get into the swing of things you will definitely see a difference.
I'm 60 in a couple of weeks and I'm not going to bullshit saying that I look 10 years younger or anything, but I definitely look better. I also feel like I've got my pre menopause mojo back which is great.
