The Cholesterol Playbook

What cholesterol does, and why context matters

Cholesterol is used in cell membranes, steroid-hormone production and bile-acid production. Understanding those roles is part of reading the panel without treating cholesterol as a substance the body should simply eliminate.

Total cholesterol combines information from several circulating lipoproteins. Our framework therefore asks what sits underneath the total: LDL, HDL, triglycerides, particle measures where available, and the person’s metabolic and family history.

The point of expanding the assessment is to add useful information. It should not turn a high LDL result into an automatic reassurance or make the standard panel irrelevant. We interpret LDL as a risk signal alongside the other findings.

Particles and the environment they move through

We look closely at oxidation, inflammation and insulin resistance. The metabolic environment matters, and two superficially similar panels may need different follow-up.

Particle number and particle size answer different questions. ApoB and LDL-P help describe particle burden; a particle-size result adds different information. A triglyceride-to-HDL ratio is not a direct measurement of either.

We therefore consider the particle picture alongside blood pressure, glucose regulation, smoking history, family history and known disease. A favourable finding in one area does not cancel the rest of the assessment.

The markers our framework brings together

Triglycerides and HDL: a readily available view of the lipid and metabolic pattern, including a ratio calculated in the correct units.

Fasting insulin and glucose: context for glucose regulation and the metabolic concerns that may accompany a triglyceride pattern.

hs-CRP: inflammatory context. It does not identify the location or cause of inflammation by itself.

LDL-P and ApoB: ways to examine particle burden when the question requires more than cholesterol concentration alone.

Lp(a): a distinct inherited-risk consideration that should not be assumed from the ordinary LDL result.

The usefulness of an additional marker depends on the question it will answer. We explain that question before adding more testing.

How we use house reference ranges

Wesnoski uses functional reference points to organise the coaching review. Examples include ApoB below 80 mg/dL, LDL-C below 100 mg/dL and hs-CRP below 1.0 mg/L.

These are coaching reference points, not a complete treatment decision. Existing cardiovascular disease, inherited risk, age and the rest of the clinical picture can change the appropriate goal.

The reference points are read alongside the person’s history and trajectory. The purpose is to decide what deserves attention and what the next result will help us evaluate.

Calculate the triglyceride-to-HDL ratio correctly

Use triglycerides and HDL in mg/dL for the ratio examples in this guide. Divide triglycerides by HDL: 75 divided by 65 is approximately 1.15; 110 divided by 52 is approximately 2.12; 180 divided by 38 is approximately 4.74.

These examples show different patterns worth interpreting alongside the rest of the panel. They do not prove which LDL particles are present or establish a person’s future outcome.

If your report is in mmol/L, multiply triglycerides by approximately 88.57 and HDL by 38.67 before calculating the mg/dL-based ratio. Do not compare an unconverted ratio with a target taken from a differently expressed panel.

The insulin connection in our teaching

The liver packages triglycerides into VLDL. Changes in glucose regulation and lipid exchange can accompany higher triglycerides, lower HDL and changes in LDL particles. This is why our lipid review often includes fasting insulin and glucose.

The coaching response connects the panel with the actual routine: meals, alcohol, liquid calories, movement, resistance training, sleep and recovery. We also review other relevant contributors rather than assuming every lipid pattern has the same cause.

The Metabolic Panel Cheat Sheet explains the daily levers in more detail. The two guides belong together because a lipid result and the person’s metabolic circumstances should not be interpreted in isolation.

Lp(a) and inherited risk

Lp(a) is a lipoprotein with an additional protein component, apolipoprotein(a). Our framework treats it as a distinct inherited-risk consideration, rather than assuming a healthy routine makes it irrelevant.

Read the result in the units provided by the laboratory. mg/dL and nmol/L describe different quantities and should not be converted using one universal multiplier.

An elevated result adds context to the management of the other risk factors. It does not make an adverse outcome inevitable, and a favourable result does not remove other concerns.

What a calcium score adds

A coronary artery calcium scan measures calcified plaque. In our educational framework, that is different information from a blood marker describing a risk factor.

A score of zero means no detectable calcified plaque on that scan. It does not describe every kind of plaque or decide medication use on its own. Age, symptoms, family history and the rest of the assessment remain relevant.

Remember that different tests answer different questions. The test should be selected for a reason, and its result interpreted within the person’s circumstances rather than used as a stand-alone permission slip.

The food and training work

We emphasise recognisable meals, appropriate protein, tolerated plant foods, suitable fats and a routine the person can sustain. Practical food examples include fish, olive oil and eggs.

We review highly processed foods, alcohol, liquid sugar and the balance of the diet. We review cooking-fat choices, but one ingredient cannot account for the entire lipid profile. Individual responses still need to be followed.

Fish and omega-3 support appear in our triglyceride discussion. The choice of food or supplement, its purpose and its compatibility with the rest of the plan should be explicit rather than attached automatically to every cholesterol result.

Training and daily movement sit beside nutrition. We use the repeat panel and the wider response to assess the plan rather than promising that one swap will settle every marker.
