Weight Loss: Why You Can’t Separate Hormones from the Nervous System (Episode 52)

When people talk about weight gain in midlife, estrogen is usually the first hormone mentioned — and for good reason.

Estrogen is not only a reproductive hormone. It influences:

When estrogen levels decline during perimenopause and menopause, multiple systems shift at once. Fat storage patterns change. Insulin sensitivity can decline. Sleep may suffer. Mood fluctuates. Energy drops.

If you’ve gained weight during this stage of life, it is not irrational to consider that hormones are involved.

However, here’s where nuance matters.

Many women are told their labs are “normal for their age.” But “normal” is a statistical category. It does not mean optimal. And it certainly does not mean you have no room to improve how you feel.

Hormones and weight loss are deeply connected — but hormones do not function in isolation.

If we’re serious about hormones and weight loss, we must talk about insulin.

Insulin is produced by the pancreas. Its job is to manage blood sugar. When you eat carbohydrates and sugar, insulin rises to shuttle glucose into cells.

But insulin does something else:

When insulin is elevated, fat burning is inhibited.

When insulin drops, fat burning becomes available.

This is why many experts in metabolic health emphasize carbohydrate reduction as a powerful lever in weight management.

The thyroid is also part of this conversation. Thyroid hormones (T3 and T4) influence metabolism and directly interact with insulin regulation. If thyroid function is suboptimal — even if labs are technically “normal” — weight loss may feel nearly impossible.

Hormones and weight loss are inseparable from metabolic regulation.

After years of experimenting, researching, and listening to clinicians and scientists, I adopted a carnivore diet — meaning I eat only animal products (with small exceptions like coffee and basic seasonings).

Yes, that challenges mainstream dietary advice.

I chose this approach because:

Carnivore functions as an elimination diet. Removing plant compounds that can trigger inflammation or digestive distress in some individuals simplifies the metabolic environment.

What benefits did I see?

I do not claim this diet is for everyone. But I do believe insulin regulation and metabolic flexibility are foundational for weight loss — especially in midlife.

When carbohydrate intake is significantly lowered, insulin drops. The body shifts toward burning fat and producing ketones. Many people report steadier energy, fewer cravings, and improved mental clarity once fat-adapted.

If someone tells me they eliminated sugar and carbs but continue gaining weight, I become curious about how consistently insulin is being lowered — and what other hormones (thyroid, cortisol) are doing.

Another controversial topic in midlife health is Hormone Replacement Therapy (HRT).

For decades, many women were taught to fear HRT due to interpretations of large clinical trials that linked it to breast cancer and cardiovascular risk. More recent analyses by physicians such as Dr. Peter Attia, Dr. Sara Gottfried, and others have brought nuance to those interpretations.

Some women may benefit from HRT — not just for hot flashes, but for brain health, metabolic function, and overall quality of life.

I personally chose to begin HRT before menopause, after careful consideration and research, because I rely professionally on cognitive sharpness, memory, and communication. For me, preserving brain health was not optional.

Do all women need HRT? No.

Should women be informed enough to make educated decisions? Absolutely.

Hormones and weight loss intersect here as well. When estrogen declines, fat distribution shifts. Insulin sensitivity changes. Muscle mass can decrease. Strategic hormone support may help some women stabilize these variables.

Weight loss is not just about food and hormones. It’s also about recovery.

During periods of high stress in my life, I developed insomnia. Meditation apps didn’t help. Sleep hypnosis didn’t help.

What helped was stabilizing my body.

Once my hormones were better regulated and my diet supported metabolic health, I noticed something powerful: my nervous system calmed down.

Exercise — especially moderate outdoor activity — improved my sleep. Stabilized energy reduced anxiety. Nourishment created safety signals in my body.

The nervous system does not regulate well in a metabolically depleted body.

This is the piece I believe many conversations miss.

After the early health-focused episodes of my podcast, I shifted toward business, money, and communication.

Why?

Because financial stress is one of the strongest chronic stressors in adulthood. And chronic stress affects hormones. And hormonal dysregulation affects weight, cognition, and resilience.

You cannot build a stable business or make strong financial decisions in a chronically inflamed, sleep-deprived, hormonally unstable body.

Health and wealth are not separate domains.

If you are struggling with weight gain in midlife, educate yourself about what happens hormonally during this time so that you know what options you have. You do have options! Weight loss is not a moral issue. It is not a willpower issue. It is often a metabolic and hormonal issue — intertwined with nervous system regulation.

The more integrated your thinking, the more empowered your choices.
