Hypertension: What If the Problem Isn't Salt or Fat?

Hypertension: What If the Problem Isn't Salt or Fat?

by Laurent Glatz – for Athletic Carnivore

Hypertension is often presented as a simple story: too much salt, too much fat, not enough discipline. This explanation has the advantage of being easy to repeat. But it fails to explain why so many people remain hypertensive despite reducing salt intake, nor why blood pressure sometimes improves rapidly in those who primarily cut carbohydrates.

The body doesn’t regulate blood pressure solely through salt. It regulates it through the kidneys, blood vessels, the nervous system, blood volume, insulin, cortisol, inflammation, the endothelium, and the liver. Reducing this entire complex system to “eat less salt” is like looking at an electrical panel and blaming a single light bulb.

Insulin is one of the major blind spots. When insulin remains elevated, it promotes sodium retention by the kidneys. More sodium retained often means more water retained, thus increasing circulating blood volume. In certain profiles, this can contribute to higher blood pressure. The problem isn’t sodium alone—it’s sodium in a hormonal context that favors retention.

This is precisely why some people on low-carb or carnivore diets actually need to increase their salt intake. When insulin drops, the kidneys retain less sodium. Water levels decrease, blood pressure can shift, and cramps or dizziness may appear. The same amount of salt does not have the same effect in a hyperinsulinemic body versus one with low insulin. Context is key.

Triglycerides tell another part of the story. A profile with elevated triglycerides, low HDL, increased waist circumference, and probable fatty liver often indicates insulin resistance. This condition alters vascular function. The endothelium, the inner lining of blood vessels, becomes less flexible, less responsive, and more inflammatory. Pressure rises in a system that has lost its elasticity.

The liver also plays a central role. When saturated with excess glucose, fructose, and energy, it produces more triglycerides, stores more fat, and contributes to metabolic inflammation. Fatty liver is not isolated from blood pressure—it belongs to the same silent syndrome: hyperinsulinemia, visceral fat storage, inflammation, vascular stiffness, and lipid disturbances.

Cortisol adds yet another layer. A stressed organism mobilizes more energy, heightens alertness, alters blood sugar, and can increase vascular tension. Poor sleep, excessive caffeine, inadequate recovery from training, or fluctuating blood sugar can make blood pressure reflect an overactive nervous system. Again, blaming salt alone is too simplistic.

A well-managed carnivore or low-carb approach acts on multiple levers simultaneously. It reduces carbohydrate load, thus lowering insulin demand. It often decreases triglycerides. It can reduce liver and visceral fat. It stabilizes hunger and energy. It sometimes lessens retention. But it also requires intelligent management of salt, water, potassium, magnesium, sleep, and stress. The goal is not to replace one dogma with another but to understand the terrain.

In the short term, some people see their blood pressure drop quickly when they reduce carbohydrates. In the long term, improvement often depends on losing visceral fat, lowering insulin, vascular recovery, and nervous system stability. It’s a transformation of the terrain, not just a condiment adjustment.

The real question is not: “How much salt do you eat?” It is: In what hormonal, inflammatory, and metabolic context does this salt arrive?

What if your blood pressure told not just the story of your salt shaker, but the full state of your insulin, liver, triglycerides, and nervous system?
