Tag: Fasting and ketosis

According to a study published in the journal *Nutrients*, intermittent fasting can promote weight loss and reduce risk factors for heart disease by triggering the metabolic state of ketosis. If fasting, the time it takes to enter ketosis can range from as little as 12 hours for some individuals to several days for others, depending on various personal factors.

It is generally understood that it takes most people 2 to 4 days of consuming very low carbohydrates, or less than 50 grams per day, to enter a state of ketosis. This process, however, can vary significantly depending on individual factors, impacting precisely how long without sugar to go into ketosis.

The human body possesses an impressive ability to switch its primary fuel source from glucose to fat when food is scarce, a process central to fasting. This metabolic flexibility is crucial for understanding how much fat does your body use when fasting, as it allows for the efficient mobilization of stored energy reserves.
