By the time most women find me, they've already put in the work.

They've tightened up their diet, sometimes significantly. They've added workouts, changed workouts, increased intensity. They've gone to their doctor, had labs drawn, and been told everything looks normal. Some have been told it's stress. Some have been told it's depression. Almost all of them have been told, in one way or another, that aging is the explanation and adjustment is the prescription.

They arrive skeptical. Not of me specifically, but of the possibility that there's actually an answer.

This is something I hear often. And it makes complete sense, when every test comes back normal and every provider sends you home with the same non-answer, eventually you start wondering if you're the problem.

You weren't debugging the wrong effort. You were debugging the wrong system.

In perimenopause, fat cells, particularly around the abdomen, begin developing insulin resistance independently. Not because of what you ate. Not because of what you didn't do. Because estrogen is part of the signaling system that keeps fat tissue functioning as a metabolic buffer, and when estrogen declines, that buffer fails.

Think of it this way: healthy fat tissue is supposed to absorb excess energy and hold it. Estrogen helps run that system. When estrogen drops, the fat cells stop absorbing efficiently. Energy that should stay in fat tissue spills instead into the liver, the muscles, the bloodstream. Body composition shifts. Triglycerides rise. Fasting insulin climbs. Energy drops. The brain that used to process information fast and cleanly starts working harder for the same output.

And a standard lab panel, fasting glucose, A1c, basic metabolic, often shows nothing yet.

This isn't a subtle distinction. It means that for the two to three years before conventional screening catches anything, a woman can be symptomatic, frustrated, doing everything she's been told to do, and receiving zero clinical confirmation that anything is actually wrong.

That gap is where most of my patients have been living.

What changes the outcome

The intervention window in early perimenopause is real and it matters. Fasting insulin and triglycerides are more sensitive early markers than glucose. Identifying fat cell insulin resistance at this stage, before it becomes systemic, is where the most meaningful clinical work happens.

Three things move the needle, and each one targets the exact mechanism that changed.

Protein at every meal reduces the demand on compromised fat tissue to manage blood sugar on its own. Resistance training builds skeletal muscle, which is your body's largest alternative system for absorbing and using glucose when fat tissue can't. And sleep is not a lifestyle preference at this stage. It is a metabolic intervention. One night of poor sleep measurably worsens fat cell insulin sensitivity by morning. For women already dealing with disrupted sleep in perimenopause, which is most of my patients,  this compounds faster than any other variable in the picture.

This is why the protocol is sequenced the way it is. Sleep first. Metabolism second. Not because the other pieces don't matter-  because none of them work as well on a foundation of broken sleep.

The solution isn't complicated. What's been missing isn't the effort. It's the correct identification of the problem.

The complete system

If the clinical picture I've described here matches what you've been living, the next step is a protocol built around it, sequenced in the order your body needs it, with the clinical reasoning behind every recommendation.

That's what Get Your Edge Back was designed to do. Not generic wellness advice. A six-week system built around the specific biology of what actually changed.

If you've been told you're fine when you know you're not, that's not a gap in your effort. That's a gap in who's been looking.
