What is intermittent fasting?
There are two different periods of intermittent fasting:
- The eating period, during which you eat your meals.
- The fasting period is when you can only consume water, and zero-calorie beverages and not eat anything.
What are the stages of fasting?
When you finish the last meal of your day, your fasting period begins. During the fasting period, your body goes through different stages hour by hour, depending on your fasting plan.
The five main stages of fasting are as follows:
Anabolic (0-4 hours)
Your body starts digesting the food you have eaten. This is your body’s growth stage.
Catabolic (4-12 hours)
The breakdown phase starts when your body starts to look around for a new energy source. Stored glucose (glycogen) becomes your body’s first choice.
Fat Burning (12-18 hours)
The fat-burning stage begins after 12 hours of not eating anything when your body has depleted its glycogen stores.
Ketosis (18-72 hours)
The body keeps looking for more sources of energy and begins transforming fatty acids into small particles, called ketones or ketone bodies. This is when you enter the ketosis stage.
Deep Ketosis (72+ hours)
Rejuvenation of the immune system and production of stem cells begins. But this is not an easy stage to reach and must only be attempted by very advanced intermittent fasters, under the supervision of a doctor.
How does the fasting fat burning stage work?
Your body enters the long-awaited fat-burning phase when it runs out of its glycogen stores. This starts approximately the 12th hour of your fast.
The fat-burning stage continues until the 18th hour of your fast. This is especially important for people who are trying to lose weight without losing muscle mass.
After the 18th hour of the fast, the fat-burning stage continues on a more cellular level as the body consumes ketone bodies for energy.
Does intermittent fasting burn belly fat?
Let’s give you the good news: Intermittent fasting does burn belly fat! People who fast indicate that their waist circumference reduced by 4–7% by the time they had fully adopted this eating pattern in their lives.
The most important thing to be cautious about is that although fasting can help you to a certain extent, burning the fat in specific areas of your body requires a bit more effort.
Doing cardio exercises regularly and building healthy eating habits are essential for losing belly fat.
Here are the top things you can do to burn belly fat:
Whether it’s at-home cardio, swimming, cycling, or bodyweight workouts, your muscles need to work to burn fat. You can get the Fitness Kompanion to get hundreds of bodyweight workouts suitable for all levels.
2. Build healthy eating habits
Eat more protein and fiber-rich foods to feed your muscles with good nutrients and to support your digestion. Eat less refined carbs and avoid junk food too.
You should consume about 2 liters of water a day. This equates to approximately 8 glasses of water. This amount should be increased still further on your workout days. Here are some tips to increase your water intake.
4. Sleep adequately
A healthy adult needs at least 7 hours of sleep per day. Even if you think you’re satisfied with less sleep, your brain needs at least 7 hours of sleep to perform all its functions. If you’re suffering from insomnia, you may be able to combat it with a few lifestyle changes.
To sum up
Fasting is a very powerful tool for weight loss and fat burn. But you also have to remember that it’s not a magic wand and that it won’t be as effective if you continue with bad life habits such as smoking, excessive alcohol consumption, a sedentary lifestyle, and eating mostly junk food.
However, when combined with healthy lifestyle choices, intermittent fasting can create big changes in your body.
