So, my 75-year-old MIL just got her bodyfat tested. At 5'2" and 125 lbs, it's 44%. Her doctor's recommendation is to get her weight between 106-118 lbs; her set-point for many years was about 110 lbs, but she now has osteopenia and almost no muscle mass. I don't think losing pounds is going to help her health.
I'm at a bit of a loss of what to tell her to do (considering the below info).
She lost 45 lbs in 9 months three years ago, after being diagnosed with diabetes and going low-carb, and she's kept it off since - maintained her current weight all this time. She's very good at complying with her diet, her blood sugar is great. She eats until she's full, but doesn't eat much food, and mainly for this reason her diet could surely be more nutrient-dense; but she eats mostly meat and veggies, snacks on nuts and some fruit, doesn't eat low-fat. More 'paleo' than almost anyone else I know.
I can't believe her BF is so high still. She does a lot right. If anyone has an explanation for why this would happen, I'd be curious to know.
She works retail (constant movement) 3-4 days per week and does all her own housework (lives alone in a large 3-bedroom house and cooks every night), so she's pretty active for her age, but I think more structured exercise could help a lot; at least it would build her a little more muscle, even if there was no fat loss. I might try to get her lifting weights/doing bodyweight stuff a couple times per week.
I don't think she'd be down with the 'leptin reset'; she just doesn't eat that much food! I'd be surprised if she got anywhere near 50g protein in an entire day.
If anyone has any other suggestions on how to help her, I'd much appreciate it.
