Looking for advice and other women’s experiences of exercise in combination with intermittent fasting.

I’m nearly 53 and two years post-menopausal, and having been reasonably active but never an athlete nor into systematic workouts for much of my life, I first started exercising regularly just before the pandemic, then stopped after I fell and broke my arm, and have been more or less back on a fitness routine for about a year.

For about a year and a half, I’ve been fasting for longer and longer periods (first 14-10, then 16-8, and now most days I only eat once, though I’m not strict about it, and 16-8 is still the case pretty often.

I exercise lightly, as far as I can tell - 45 minutes bodyweight and suspension trainer 4 times a week, plus 10 - 15,000 steps a day. I don’t push myself hard, and I’m not the kind of person who will ever nerd out on the numbers or details - not going to keep track of macronutrient intake or anything. I’m slowly getting stronger and leaner and more flexible- I feel pretty good about what I’m doing.

All the same, I can’t find specific advice about being post-menopausal and gaining muscle (a friend andI have a kayaking trip planned for the summer and I want to be sure I’m strong enough to get the most out of it)

I try to eat a lot of protein, but eating once a day makes that difficult. I know I shouldn’t be eating my meal of the day at night, but my current life circumstances make that the only option. I don’t feel hungry, I don’t feel weak, or anything. I feel good, better than what has been my normal in adulthood, and as I say above, I know I’m gaining strength. I was just wondering if any of the gyns here have experiences or wisdom to share - I can’t find anything on the broader internet that aimed at women my age exercising and fasting.
