What we actually do

Menopause is Mount Everest. We're your sherpa.

Nobody summits Everest alone, and nobody should have to figure this out alone either. We carry the heavy part of the pack: the reading, the research, the sorting through what's real and what's marketing. You climb. We guide, we carry, and we make sure you come back down feeling like you conquered something.

01
We read the research so you don't have to

We follow published work from leading women's-health specialists — endocrinology, oncology, sleep, metabolic and menopause medicine — and summarize what actually matters for your day. Plain English, no jargon, no 300-page book.

02
We tell you what's worth buying — and what to skip

Supplements, trackers, creams, powders, programs. Most of it isn't worth your money and we'll say so out loud. When something does earn its place, we tell you why and what to expect from it.

03
We give you the daily actions

Nutrition, movement, light, sleep and stress — turned into small specific things to do today, matched to your cortisol type and your stage. Not a lifestyle overhaul. The next right step.

04
We stay with you — that's the accountability

A coach who knows your answers, a community of women in the same season, and check-ins that keep the streak alive. Knowledge without accountability is just more reading.

To be clear about what we're not: we're not your doctor and we don't diagnose or treat anything. We're the guide who's read everything, walked the route before, and knows where the footing is bad. Bring what you learn here to your clinician — the best results happen when you do.

In their words

We asked women why they clicked. Here's what they wrote.

"I just want to feel like myself again."

Post-menopause

"I have been working out for a year and can't seem to get the fat under control."

Post-menopause

"I want to be able to feel better about myself and to run with my grandchildren and to take pictures and not feel embarrassed."

Post-menopause

"I've always been at a good weight my whole life. Perimenopause started and I went up two sizes in five years."

Perimenopause

"I'm tired of everyone telling me I'm fine when I know I'm not. I'm tired of the sugar cravings and my belly fat."

Menopause

"I don't recognize myself, and I miss the old me."

Menopause

"Just want to feel better. I'd developed the 'must just be old age' attitude and I want to change that."

Post-menopause

"I want to start living life again instead of just watching it pass by."

Post-menopause

Hi, I'm Curve — your cortisol coach.

I'll walk you through a 60-second diagnostic and help you spot the exact place your rhythm is breaking — sunrise spike, 3AM wake-up, 4PM crash — then coach you through it daily, alongside a community of women on the same curve.

Cortisol 101 · 90-second read

Cortisol isn't the villain. A mistimed curve is.

You've been told to "lower your cortisol." That's the wrong goal. Cortisol is your body's morning espresso — you want it high early and low late. The problem is when the timing flips.

1 · The rhythm you want

In a healthy woman cortisol peaks 30–45 minutes after waking (the Cortisol Awakening Response), then declines all day. That morning spike wakes your brain, mobilizes energy, and primes focus. Low cortisol at night is what lets you sleep.

Adam & Kumari, Psychoneuroendocrinology (2009)
2 · The rhythm that breaks you

Under chronic stress the curve inverts: flat in the morning, spiking in the afternoon and night. That's the 3 PM crash, the sugar craving, the 2 AM wakeup, the puffy morning face — same broken curve, different symptoms.

Hirotsu et al., Sleep Science (2015)
3 · Why the belly

Mistimed cortisol drives fat storage specifically to the abdomen — even in lean women. Epel's landmark study measured it: women with higher cortisol reactivity carried significantly more visceral fat, regardless of diet.

Epel et al., Psychosomatic Medicine (2000)
The upshot

The goal isn't zero cortisol. It's a properly timed curve — high morning, low night. You can't out-diet, out-run, or out-meditate a broken rhythm. The 5-day transformation resets the timing, and step one is knowing which of the 4 broken patterns you're on.

If you recognize 3+ of these

You're not lazy. You're not broken. Your cortisol curve is inverted.

  • You wake up between 2 and 4 AM with a racing mind — even when you're exhausted
  • The belly weight won't move no matter what you eat or how much you walk
  • You need caffeine just to feel human, then crash at 3 PM
  • Your face looks puffy in photos — especially mornings
  • PMS or perimenopause symptoms have gotten noticeably worse
  • You've tried keto, fasting, therapy, supplements. Something's still off.
The diagnostic

The 4 cortisol types

Your quiz result will match you to one — with a personalized transformation.

Type 1 · Most common
Wired & Tired
Elevated evening cortisol. Belly fat, 3 AM wakeups, puffy mornings.
Type 2 · Depleted
Burned-Out
Flat cortisol curve. Bone-deep fatigue, coffee stops working, hair thinning.
Type 3 · Reactive
Cortisol Craver
Spike-crash-crave loop. Sugar cravings, weight cycling, afternoon crashes.
Type 4 · Elevated
Restless Runner
Cortisol never drops. Anxiety, racing mind, can't unwind at night.
The 5-day transformation

You will feel the difference by day 3.

The research

Built on peer-reviewed cortisol science.

Every protocol in the transformation traces back to a published study. A short reading list:

  1. Morning light within 30 min of waking anchors the cortisol rhythm.
    Wright et al., Current Biology (2013). Entrainment of the human circadian clock to the natural light-dark cycle.
  2. Chronic stress inverts the daily cortisol slope.
    Adam & Kumari, Psychoneuroendocrinology (2009). Assessing salivary cortisol in large-scale studies.
  3. Higher cortisol reactivity → more visceral abdominal fat in women.
    Epel, McEwen, Seeman et al., Psychosomatic Medicine (2000). Stress and body shape.
  4. Poor sleep raises next-day cortisol; high cortisol wrecks next-night sleep.
    Hirotsu, Tufik & Andersen, Sleep Science (2015). Interactions between sleep, stress, and metabolism.
  5. Slow diaphragmatic breathing (e.g. 4-7-8) reduces cortisol within minutes.
    Perciavalle et al., Neurological Sciences (2017). Deep breathing lowers cortisol and improves attention.
  6. Perimenopause amplifies the cortisol–weight loop.
    Woods et al., Menopause (2009). Cortisol patterns across the menopausal transition.
