You went low carb.

You added the protein and the fat.

Your blood sugar app says you’re “stable.”

And the scale has climbed 15 pounds in the last two years. Your belly is bigger. Your energy is lower. Your sleep is worse. 

And every “expert” is telling you to cut MORE carbs and add MORE protein.

I’m Ciara, a 49 years young nutritionist specializing in women’s health and hormones for over 20 years, and here’s what they’re not telling you:

Chronic low carb after 40 doesn’t fix insulin resistance. It hides it.

A high-fat, low-carb meal “controls” a glucose spike for a couple of hours. But it suppresses your body’s ability to oxidize carbs for days afterward. 

You become metabolically inflexible. Your body forgets how to burn glucose efficiently. And the moment you eat any carb, your blood sugar rockets and you store it.

That’s not insulin resistance reversed. That’s insulin resistance protected.

Then there’s your thyroid. A 1986 study showed women on a low-carb very low calorie diet had a 34.6% drop in active T3 versus 17.9% on a higher carb version of the same calories. 

Your active thyroid hormone tanks. Your metabolism slows. Your hair thins. Your hands get cold. The 2025 ketogenic literature confirms the same mechanism: low carbohydrate availability impairs T4 to T3 conversion.

Then add perimenopause, which independently reduces metabolic flexibility because of falling estrogen.

You are not failing. You’re using the wrong tool for the wrong stage of your life.

This is exactly what I teach in the Hormone Stacking Method. The ORDER you fix things in. Not more rules. Not more restriction. The sequence.

I’m running a free masterclass on it May 29th.

Comment METHOD and I’ll send you the link.

Save this for the next time someone tells you to cut more carbs.

Follow for the metabolic science your trainer doesn’t have.
