This unusual study examined what's called a "Lean Mass Hyper-Responder" - a lean, healthy person who develops very high LDL ("bad") cholesterol levels when following a ketogenic (very low-carb) diet. These individuals typically see their cholesterol jump above 200 mg/dL despite being metabolically healthy, which creates a puzzle for both patients and doctors about whether this poses actual health risks.
The researchers conducted a fascinating experiment on one such person whose LDL cholesterol had reached 384 mg/dL on a ketogenic diet. In the first phase, they had this person eat 12 Oreo cookies daily (adding 100 grams of carbs) while maintaining ketosis through supplements. Remarkably, this reduced their LDL cholesterol by 71% to just 111 mg/dL. After a three-month break where cholesterol returned to high levels, they tested rosuvastatin (a powerful statin drug) for six weeks, which was less effective than the cookie intervention.
The study supports the "lipid energy model," which suggests that in very lean people on ketogenic diets, the body may increase cholesterol production and transport to meet energy needs when carb stores are depleted. Adding carbohydrates appears to reduce this demand, thereby lowering cholesterol levels.
While this is only one person's experience and shouldn't guide treatment decisions, it highlights the complex relationship between diet, body composition, and cholesterol metabolism. For patients experiencing similar cholesterol elevations on low-carb diets, this research suggests the importance of working with knowledgeable healthcare providers who can interpret these findings within the context of overall metabolic health rather than focusing solely on cholesterol numbers.
