Cholesterol: The Numbers You’re Watching — and the Ones That Actually Matter

Few lab results cause more panic than cholesterol numbers.

A single blood test comes back “high,” and suddenly:

• Saturated fat is blamed

• Eggs are questioned

• Medication is suggested

• Fear replaces understanding

But cholesterol is not the villain it’s been made out to be. In fact, cholesterol is essential for life, and most people are focusing on the least important numbers while ignoring the real drivers of cardiovascular risk.

Let’s clear the confusion.

What cholesterol actually does in the body

Cholesterol is not waste. It is a critical biological building block.

Your body uses cholesterol to:

• Build and stabilize cell membranes

• Produce stress hormones (like cortisol)

• Produce sex hormones (testosterone, estrogen, progesterone)

• Support brain function and memory

• Manufacture vitamin D

• Produce bile, which allows you to digest fats and absorb vitamins A, D, E, and K

This alone should make one thing obvious:

The body does not treat cholesterol as poison.

“Good” vs “bad” cholesterol — the oversimplified story

There is only one cholesterol molecule.

What differs is the carrier protein that transports cholesterol through the bloodstream.

• HDL carries cholesterol back to the liver for reuse or recycling

• LDL carries cholesterol from the liver to tissues that need it

LDL is not inherently dangerous. In fact, most cholesterol is transported safely every day without incident .

The problem is not LDL itself — it’s what type of LDL.

The real problem: small, dense LDL (sdLDL)

The most atherogenic (artery-damaging) particles are small, dense LDL (sdLDL).

These particles:

• Penetrate artery walls more easily

• Oxidize more readily

• Trigger inflammation

• Contribute to plaque formation

Larger LDL particles are far less problematic.

Key insight:
Many standard lipid panels do not measure sdLDL unless specifically requested, yet this marker is far more predictive of cardiovascular risk than total cholesterol or LDL alone.

Triglycerides: the metabolic red flag

Triglycerides are not cholesterol — they are stored energy, created when excess sugar is converted into fat.

High triglycerides usually indicate:

• Excess carbohydrate intake

• Excess sugar intake

• Chronic insulin elevation

• Metabolic dysfunction

Optimal triglyceride levels are:

• Below 150 mg/dL

But an even better metric exists.

The triglyceride-to-HDL ratio (one of the most important numbers)

The triglyceride-to-HDL ratio is a powerful indicator of insulin resistance and cardiovascular risk.

• Lower ratio = better metabolic health

• Higher ratio = higher risk

Improving this ratio almost always involves:

• Reducing carbohydrates and sugar

• Improving insulin sensitivity

• Supporting liver function

Where cholesterol really comes from

A crucial fact that often surprises people:

• ~75% of your cholesterol is produced by your liver

• ~25% comes from food

This means cholesterol levels are far more reflective of:

• Liver health

• Metabolic health

• Insulin levels

• Inflammation

—not simply dietary cholesterol intake.

Cholesterol, keto, and the liver connection

Some people see cholesterol rise when transitioning to keto. This does not automatically mean danger.

Often, it reflects:

• A liver still adapting

• Fatty liver or bile flow issues

• Gallbladder removal or dysfunction

The liver clears cholesterol using bile. If bile production or flow is impaired, cholesterol can accumulate in the bloodstream.

BBHC strategies to normalize cholesterol (without abandoning keto)

1. Eat plenty of vegetables

• Aim for 7+ cups daily

• Fiber binds cholesterol

• Antioxidants support liver detoxification

2. Support bile production

• Purified bile salts can help

• Especially important if you’ve had gallbladder surgery

3. Use choline

• Helps transport fat out of the liver

• Supports bile production

• Found in egg yolks or supplements

4. Consider niacin (vitamin B3)

• Can lower LDL

• Raises HDL

• Reduces triglycerides

5. Give your metabolism time

As liver fat decreases and insulin normalizes, cholesterol processing often improves naturally on a healthy ketogenic diet .

So in a Nutshell:

Cholesterol is not the enemy.

The real drivers of cardiovascular risk are:

• Insulin resistance

• Inflammation

• Oxidized sdLDL

• High triglycerides

• Poor liver function

Obsessing over total cholesterol while ignoring these factors is biologically backwards.

When you improve metabolic health, cholesterol usually takes care of itself.
