Loaded carry
Walking while holding something heavy, like shopping bags or dumbbells.
Mobility

The key differences

  • Haver puts more of the week into strength: about 55% against 10%.
  • Haver puts more of the week into aerobic base (zone 2): about 40% against 30%.
  • The Starretts put more of the week into mobility and stability: about 60% against 5%.
  • In plans in their style, both use 1-minute intervals for hard sessions.
  • We rate the evidence behind Haver's protocol higher: strong, against solid for the Starretts.
  • Supplements that go into a plan: Haver, none (food first); the Starretts, none (food first). Prescription items and personal stacks stay out of every plan.
  • Only the Starretts have a mobility or movement routine of their own.

Protocols side by side

Each line is rated for the evidence behind it. “Doctor only” items never go into a plan.

Training

Mary Claire Haver

  • Full-body weight training at least 2 days a week (she does 3–4), progressing gradually, ideally with a trainerStrong evidence
  • Walk at least 3 days a week; beginners start with 5–10 minutes a dayStrong evidence
  • To progress: add a weighted vest to walks, more steps, or a third lifting dayPersonal habit
  • No exercise types need to be avoided in menopause; strength, cardio, stretching and mind-body work all matterNote

Kelly & Juliet Starrett

  • Walk 8,000–10,000 steps a day, up to 12,000 if you canStrong evidence
  • Sit on the floor for at least 30 minutes a day, changing positions (cross-legged, 90/90, long sitting)Personal habit
  • Practise getting down to and up from the floor; test with the sit-and-rise testSome evidence
  • Daily deep-squat time: hold your deepest squat for five breaths as a test, plus sit-stands from a chairSome evidence
  • Daily balance practice; test standing on one leg with eyes closed (SOLEC) and putting on shoes while standingSome evidence
  • Optional rucking: start with about 2 kg for a mile, three times a week, and build up over about a monthPersonal habit

Eating

Mary Claire Haver

  • Protein about 1.5 g per kg of healthy body weight a day, with about 1.8 g/kg as a stretch goalSome evidence

  • Eat about 30 different plant foods a week (vegetables, fruit, nuts, seeds, grains, herbal teas)Some evidence
  • Anti-inflammatory, Mediterranean-style eating: limit added sugar and processed carbohydrate, add leafy greens, olive oil, berries, nuts and fermented foodsStrong evidence
  • Spread protein across meals and snacks, each paired with a healthy fat and a healthy carbohydratePersonal habit
  • She originally promoted 16:8 intermittent fasting but has pulled back, saying it can make enough protein hard to reachNote

Kelly & Juliet Starrett

  • About 800 g of fruit and vegetables a day (roughly six cups)Strong evidence
  • Protein about 1.5–2.2 g per kg of body weight; some later talks cite 1.8 g per kgSome evidence

Brain health

Mary Claire Haver

  • Points to observational data linking longer lifetime oestrogen exposure, including hormone therapy, with better cognition; not a licensed reason to start hormonesDoctor only

Weak spots to know

Mary Claire Haver

  • Several menopause specialists, quoted in a 2024 New York Times report, said she promotes hormone use beyond official guidelines; one said patients now ask for hormones to prevent heart disease or dementia, or testosterone for general wellbeing.
  • Commercial ties, stated neutrally: she owns The 'Pause Life (a multimillion-dollar business selling supplements, programmes and online courses) and a cash-pay menopause clinic. The Menopause Society discourages doctors from selling their own products, and the advertising watchdog Truth in Advertising flagged some product claims; according to the New York Times, she then hired a consultant to review the claims on her website.
  • An independent review by ConsumerLab found some of her supplements costly for what they contain, with creatine claims that overstate the evidence and a vitamin D dose at the upper safe limit.

Kelly & Juliet Starrett

  • Several central tests rest on observational data: the sit-and-rise and one-leg balance studies show that people who do poorly die sooner, not that practising the test makes you live longer. Both studies were also in Brazilian cohorts and could not rule out other explanations.
  • Some tests have no validated scoring for the general public; the Starretts themselves describe the breath-hold test as a rough benchmark rather than a lab-grade measure, and practices such as mouth-taping have little evidence behind them.
  • Built to Move deliberately leaves out cardio and strength training; for adults over 50 those remain important for heart health and muscle, so the plan works best as a base layer rather than a complete programme. Kelly's earlier Supple Leopard was criticised by one reviewer for a trial-and-error approach rather than a systematic method.
