Three things we learned this week. None of them requires a prescription.
Monday named the math. Ten percent spine bone loss across the transition. Thirty percent strength gone by 60 if untrained. One in two unable to get off the floor unassisted by 80. Wednesday named the conversation. The single most effective pharmaceutical intervention for the window, twenty years of clinicians too cautious to offer it, twenty years of patients too afraid to ask. Friday closes the week with the three deposits that compound regardless of where the HRT conversation lands.
The card shows three numbers: 40 (DEXA baseline year), 1.6 g/kg (protein floor), 2/wk (resistance sessions).
Save this. Three deposits, none of them in a prescription pad.
1. DEXA at 40.
The baseline. Most adults in the deposit decade have never had a bone scan. T-scores and Z-scores at 40 tell you where you are starting, which lets you see whether the deposits are working at 45 and 50. The scan also catches the small subset who arrive at the transition already in the osteopenia band, where the case for weighted training, the HRT conversation and the clinician who knows you lands earlier and louder. Cost typically $80 to $200 depending on city. Search the closest provider.
2. Protein floor at 1.6 g/kg.
The dose. Morton et al, Br J Sports Med 2018, the systematic review and meta-regression of 49 trials and 1,863 healthy adults, found the dose-response curve for muscle and strength gains plateaus at 1.62 g/kg/day. A 65-kilogram woman lands at roughly 105 grams a day. Most women in the deposit decade eat half that. Spread it across three to four meals so the leucine threshold gets crossed each time.
If you supplement, the brand line that matters is third-party testing. Two certifications carry weight: Informed Sport and NSF Certified for Sport. Both involve batch-level screening for banned substances and label-accuracy verification. Three brands clear that bar. ARTSN (the brand of this publication, clean-ingredient line), Momentous (grass-fed isolate, both Informed Sport and NSF Certified for Sport), and Thorne (whey isolate, NSF Certified for Sport, the clinical-brand default).
3. Two resistance sessions a week.
The signal. Saeidifard et al, Eur J Prev Cardiol 2019, the meta-analysis covered on Mon Jun 8, found two sessions a week of resistance training carried roughly 21 percent lower all-cause mortality versus none. The mechanical signal to bone is what slows the spine and hip loss across the menopause transition. The mechanical signal to muscle is what holds the strength curve. Walking does not deliver this signal. Yoga does not deliver this signal. Two sessions a week of squat, hinge, press, row and carry, heavier than feels easy, is the minimum effective dose the literature converges on. If you have never lifted before, Forever Strong by Gabrielle Lyon is the cleanest survey of why muscle is the longevity organ.
Pick one. The deposits compound. The DEXA if you have never had a baseline scan. The protein math if your meals are landing under 100 grams a day. The lifting if neither of the first two is the bottleneck. All three are decisions you make this weekend.
If you are reading this for the woman you love, the most useful thing you can do today is forward it to her. The deposits are easier to make together.
Until Monday.
