Ketosis

The Metabolic State of Fat-Burning

Ketosis is a natural metabolic state where your body burns fat as its primary fuel instead of glucose. When you restrict carbohydrates enough (typically below 20-50g per day) or fast for extended periods, your liver converts fat into molecules called ketones, which your brain and body can use for energy. This is a normal, healthy process that humans have relied on throughout evolution during times of limited food. Nutritional ketosis produces ketone levels of roughly 0.5-3.0 mmol/L—high enough to provide the metabolic benefits but nowhere near the dangerous levels (over 10 mmol/L) seen in diabetic ketoacidosis. Being in ketosis often brings mental clarity, stable energy, reduced hunger, and easier blood sugar management.
