Tag: Fasting for fat loss

While any calorie technically ends a fast according to the strictest definition, the metabolic response to fat is minimal compared to other macronutrients. This makes the question 'Will 2 grams of fat break a fast?' a nuanced one, heavily dependent on your specific fasting goals.

According to a study review, it takes an average of 18 to 24 hours of fasting for most people to significantly deplete their liver glycogen stores, though this can vary based on individual factors like activity level and diet. Understanding this process is key to maximizing the metabolic benefits of fasting, including triggering a shift to burning fat for fuel.
