Fat Is Not the Enemy

For decades, we were told that fat makes you fat. That low-fat was the goal. That the less fat you ate, the healthier you’d be. So we replaced butter with margarine, swapped whole milk for skim, filled grocery carts with fat-free cookies and reduced-fat everything — and somehow got sicker, heavier, and more hormonally out of balance than ever.

Turns out, fat was never the problem. The wrong kind of fat was the problem. And cutting out the right kind may have been one of the biggest nutritional mistakes of the last 50 years.

Your Hormones Are Built from Fat

Here’s the part that doesn’t get talked about enough: your body literally cannot make hormones without fat. Estrogen, progesterone, testosterone, cortisol, DHEA — these are all steroid hormones, and every single one of them is made from cholesterol. Cholesterol is a fat. No fat, no raw materials. No raw materials, no hormones.

That means when you drastically cut fat from your diet, your body loses access to the building blocks it needs to produce the hormones that regulate your menstrual cycle, your mood, your energy, your sleep, your metabolism, your stress response, your libido, and your ability to build and maintain muscle. If you’ve ever felt like something was “off” hormonally and you couldn’t figure out why — take a look at how much fat you’re actually eating.

But the Type of Fat Matters — A Lot

Not all fat is created equal. The fats that support your body and the fats that work against it are very different — and the easiest way to think about it is in three categories.

The fats your body loves:

These are your monounsaturated and omega-3 polyunsaturated fats. They support hormone production, reduce inflammation, protect brain function, and help your body absorb fat-soluble vitamins like A, D, E, and K. You’ll find them in avocados, extra virgin olive oil, wild-caught salmon, sardines, mackerel, walnuts, almonds, chia seeds, flaxseeds, and egg yolks (yes, eat the whole egg). These foods have been fueling human health for thousands of years.

The fats that get a bad reputation but deserve a second look:

Saturated fats. For decades they were demonized, but the picture is more nuanced than we were told. Saturated fat from whole food sources — like coconut oil, grass-fed butter, ghee, and pasture-raised animal products — plays a role in hormone production, cell membrane structure, and brain health. Your brain is nearly 60% fat, and it needs saturated fat to function. The key is sourcing: a grass-fed steak and a fast-food burger are not the same thing, even if they both “contain saturated fat.”

The fats your body does not want:

Trans fats and heavily processed industrial seed oils. These include partially hydrogenated oils (the kind found in many packaged baked goods, margarine, and fried fast food) and highly refined oils like soybean oil, canola oil, corn oil, and cottonseed oil. These fats are processed at high heat with chemical solvents, which damages their structure and makes them inflammatory in the body. They’ve been linked to increased inflammation, insulin resistance, and disrupted hormone signaling. They’re in more foods than you’d think — salad dressings, crackers, coffee creamers, granola bars, restaurant meals. Flip the label and look. If it says “soybean oil” or “canola oil” in the first few ingredients, your body is getting fat it doesn’t know what to do with.

What This Looks Like on Your Plate

This doesn’t have to be complicated. Here’s what eating enough of the right fats can look like in a normal day:

Breakfast: Two eggs cooked in grass-fed butter or ghee with half an avocado. Coffee with a splash of coconut cream.

Lunch: A big salad with olive oil and lemon dressing, grilled chicken, walnuts, and feta cheese.

Snack: An apple with almond butter. Or a handful of macadamia nuts.

Dinner: Wild-caught salmon with roasted sweet potatoes drizzled in olive oil and a side of sautéed greens cooked in avocado oil.

That’s a day full of healthy fat from real food. Nothing extreme. Nothing restrictive. Just intentional choices that give your body what it needs to keep your hormones humming.

The Takeaway

Fat doesn’t make you fat. It doesn’t clog your arteries by default. And it’s not something to be afraid of. Fat is a building block. It’s the raw material your body uses to create the hormones that make you feel like yourself — energized, balanced, clear-headed, and strong.

The question was never “should I eat fat?” It was always “what kind?” Choose the ones that come from real, whole food sources. Skip the processed, industrial ones. And watch what your body can do.
