When perimenopause brought severe fatigue, brain fog, weight gain, and irregular periods, Kay applied years of research and natural steps that got her back to feeling like herself.

 

Karrie-Ann (“Kay”) Kubatko believed she understood menopause.

She had spent years researching how it affects women’s biology, helping her best friend and other women live better through menopause and beyond.

But when perimenopause arrived for her, it still took her by surprise.

“I was in my late 30s. Menopause didn’t happen to us, you know? So I had no idea what I was about to get hit with,” she reflects.

Filling a Menopause Knowledge Gap

Kay is a PhD-trained scientist and former nuclear chemist with a long academic career. But her path took an abrupt turn after her best friend faced an emergency hysterectomy and entered surgical menopause overnight.

Almost immediately, one of the strongest women Kay knew saw her energy, cognition, and ability to work all severely impacted.

She dove into menopause research to find science-backed answers — first to help her friend, then to support other women facing the same struggle. That work ultimately led her to leave nuclear chemistry and focus full-time on menopause education and coaching. In doing so, she was filling what she saw as a major gap in women’s health care.

“Only 38% of OB-GYNs receive even an hour of menopause training,” she says. “These are specialists in women’s health, but they’re trained for childbirth.”

When Perimenopause Symptoms Hit Home

In her late 30s, Kay began experiencing symptoms she didn’t immediately recognize as perimenopause:

  • Severe exhaustion that made even basic daily tasks feel difficult
  • Brain fog that interrupted her ability to find words mid-sentence or remember names
  • Weight gain around her middle, despite eating and exercising the same as before
  • Irregular and heavy periods

Because the symptoms appeared during COVID lockdown, she assumed they were tied to the unusual stress, isolation, and disrupted routines.

Unlike surgical menopause — which hits suddenly — perimenopause arrives through gradual shifts that are easy to dismiss. Menopause follows, on average, around age 51.

Many women associate menopause primarily with hot flashes, Kay says. But symptoms often extend far beyond that, including disrupted sleep, exhaustion with midafternoon crashes, weight gain around the belly, brain fog, and irregular cycles.

Working With — Not Against — Menopause Biology

Like many women, Kay thought she could work harder, eat better, and sleep more to change her symptoms.

But eating less and exercising more only made things worse.

That’s when she shifted her approach to match her changing physiology.

“Our body’s needs change because our body’s chemistry changes,” she says.

Although she is pro–hormone replacement therapy (HRT) for women who are good candidates, Kay chose a non-HRT path herself. A family history of breast cancer and dense breast tissue made her cautious, leading her to pursue natural menopause strategies instead.

Rather than guessing, she focused on identifying what was driving her symptoms — insulin resistance, cortisol dysregulation, or changing sex hormones — and adjusted her lifestyle accordingly:

1. Eating Differently

As estrogen declines, insulin sensitivity and cortisol levels can shift, Kay explains.

“The second we hit perimenopause, our nutritional needs change,” she says.

Instead of restricting food, she fueled her body appropriately.

  • She ate about 2,000 calories per day, without skipping meals.
  • She prioritized protein early in the day to stabilize blood sugar and energy.
  • For healthier cortisol levels, she avoided caffeine until after eating. Cortisol is the body’s primary stress hormone, released by the adrenal glands to help regulate energy, blood sugar, inflammation, and the sleep–wake cycle.

2. Supporting Circadian Rhythm

  • Kay made morning sunlight a daily nonnegotiable, helping regulate cortisol patterns, circadian rhythm, and vitamin D levels.

3. Rethinking Exercise

Menopause accelerates muscle loss, which directly affects metabolism, according to Kay.

  • Kay focused on preserving muscle with short, frequent strength moves — squats while cooking, push-ups at the counter, and resistance throughout the day. No expensive gym membership required.
  • She also embraced music as therapy, choosing a daily theme song — “Raise Your Glass” by P!nk — and dancing like no one’s watching.

“I make sure every single day I do something for my muscles,” she says.

As her physiology stabilized, Kay’s symptoms eased.

Her energy returned. The brain fog lifted. She lost 38 pounds in five months. And, she felt like herself again.

A New Playbook for Menopause

Today, Kay helps women reframe perimenopause and menopause as a biological transition, not something to endure or power through. It just takes a new playbook.

The tactics she used and recommends can help women in before and after menopause, but she encourages women to start them as soon as they suspect transitions starting.

“The more women can recognize perimenopause, the more small changes they can make, that will make their transition even more powerful for them, and easier,” she says.

While she did not use HRT personally, she supports its use for women without contraindications, such as estrogen-dominant breast cancer. She also cautions against online HRT without labs and individualized dosing.

For Kay, menopause marked the moment she stopped fighting her body and started listening to it.

Once she did, everything changed.

Today, “Professor Kay” helps women navigate perimenopause and menopause using bio-individual strategies grounded in science and lab data. She guides women through her coaching practice and her Substack newsletter, The Menopause Professor.

The Steps That Helped

  • Morning sunlight — Getting outside within 30 minutes of waking to reset circadian rhythm and support healthy cortisol patterns.
  • Protein-first mornings —Eating protein within the first hour of waking — before caffeine — aiming for about 30 grams to stabilize blood sugar and energy.
  • Caffeine timing — Delaying caffeine until after food to avoid overstimulating stress hormones during a hormonally sensitive phase.
  • Muscle preservation — Protecting muscle daily with short, simple resistance moves to support metabolism and bone health.
  • Daily movement with joy — Using upbeat music and dancing as a form of mood regulation and stress relief.
  • Brain novelty — Challenging cognitive health by learning or trying something new every day, not just repeating familiar tasks.
