When Does Fat Burning Start During Intermittent Fasting?
Intermittent fasting has become a popular diet trend in recent years, as it is a great way to lose weight and improve your overall health. But many people are wondering: when does fat burning start during intermittent fasting? The answer may surprise you.
By 12 hours, you’ve entered the metabolic state called ketosis (Anton et al., Obesity 2018). In this state, your body starts to break down and burn fat. Some people can enter a fat-burning stage in as little as 12 or 13 hours of fasting, while others may need to wait until 16 hours. It all depends on your diet and how much carbs you are eating.
The human body usually starts to burn fat after remaining in a fasted state for over 12 hours. This is because the body thinks the lack of food is a sign of starvation, so it starts to break down stored fat for energy. This starts approximately the 12th hour of your fast. The fat-burning stage continues until the 18th hour.
This is especially important for people who are on a low-carb diet. Research has found that people eating a low-carb diet may enter a fat-burning stage in 12, 13, or 14-hours of fasting. However, people eating high carbs need to enter phase 3 (16+ hours of fasting) before they can start burning fat.
How Intermittent Fasting Works
Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat. This brings us into Phase two, 4 to 16 hours. Phase two is when fat burning can begin. After you process the meal over the last four hours, you enter the fasting state and your body begins to burn fat.
For most people, the fat burning stage begins after 12 hours of fasting. During this period, your body continues to burn fat for energy, until you reach the 18th hour. This is when you enter the third phase of fasting, and your body starts to break down muscle for energy.
