She runs five days a week. Forty-five minutes every morning. She has done this for years.
She used to be lean, strong, and full of energy. Now she is gaining weight around her midsection, her knees hurt, she is exhausted by noon, and she cannot figure out what changed.
So she runs harder. Adds an extra day. Cuts more calories.
And the weight keeps climbing.
If you understand the menopause transition, you already know what is happening.
Her body is not the same body it was five years ago. Her hormonal environment has shifted, and the exercise that once worked is now working against her.
Here is why:
Every long cardio session produces a sustained cortisol spike. For a woman with already-elevated cortisol from hormonal shifts and poor sleep, that daily run is adding fuel to the fire. Chronic cortisol drives insulin resistance, which tells the body to store fat around the midsection.
Chronic cardio is catabolic. It breaks down muscle. She is losing the metabolically active tissue that burns calories at rest, which means her metabolism is slowing while she is working harder. Less muscle equals a lower metabolic rate equals easier weight gain.
She is not building what her body actually needs. Running does not prevent sarcopenia. It does not load her bones. It does not improve insulin sensitivity the way resistance training does.
What does she need instead?
Resistance training 3–4 times per week to build and preserve muscle. Daily walking as her low-cortisol cardio baseline. Functional cardio 1–2 times per week. Rest days that are non-negotiable. And more food, not less.
Her body is not broken. Her approach is outdated for the body she has now.
That is what root-cause practitioner training teaches you to see.
