Skool Member Question: When lower carbs are eaten, my cholesterol goes up. Even if I stay lower saturated fat, lower carb makes it shoot up. Everyone freaks out, and I’m never certain if I should also freak out. What becomes very clear, once you step back and look at cholesterol through a true systems biology lens, is that not all elevations are created equal; what we casually call “high cholesterol” is not a single condition, but a collection of distinct physiological states, each driven by a different mechanism, each requiring a different intervention, and each easily misinterpreted if we rely on a single marker like low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC). At the highest level, these states fall into four primary buckets: mobilization (cholesterol is being moved), clearance defects (cholesterol cannot be removed efficiently), overproduction (cholesterol particles are being produced in excess), and genetic risk amplification (cholesterol becomes more dangerous independent of its quantity); layered across all of this, in certain individuals, is a fifth modifier, Saturated Fatty Acid Hyper-Reactivity Disorder (SFAHD), where dietary saturated fat disproportionately amplifies lipid and inflammatory signaling. If you do not identify which of these you are dealing with, you are not treating physiology; you are reacting to numbers. The first category, and the one most relevant during active weight loss, is mobilization; this is where lipolysis is increased, often in the setting of carbohydrate reduction across a spectrum of dietary patterns (Mediterranean, Paleo, Atkins, Keto, Carnivore, whether <150g, <100g, <50g, or <20g), where the body shifts from reliance on incoming glucose to stored energy. As adipocytes release triglycerides, they also release cholesterol; the largest storage depot of cholesterol in the body is not the liver, but the fat cell itself. So when you begin “emptying the warehouse,” you are not just moving out fuel—you are moving out packaging material as well; blood cholesterol rises not because something is broken, but because something is finally moving. This is the “cleaning out the storage unit” analogy, where everything that was hidden is now in the parking lot, and it looks worse before it looks better. A more extreme expression of this exists in the Lean Mass Hyper-Responder (LMHR) phenotype, where lean, insulin-sensitive individuals exhibit very high LDL-C alongside low triglycerides and high HDL; here, the system is not congested—it is operating at high speed, with lipid particles constantly trafficking energy, unloading triglycerides, and returning cholesterol-enriched. This is not a traffic jam; it is a high-speed logistics network. Clinically, the question is not panic, but context; ApoB, LDL-P, and longitudinal markers (like CAC) determine whether this is benign adaptation or emerging risk.
