Intermittent Fasting by Chronotype: Adjusting Your Eating Window for Optimal Results
Intermittent fasting is a popular dietary strategy that has been gaining traction in recent years. It is a form of time-restricted eating that involves shortening your eating window and fasting for a period of time. Research has shown that intermittent fasting can improve “verbal memory, executive function and global cognition” as well as memory. You can boost your brainpower and mood by incorporating intermittent fasting into your diet. But the key to success is understanding your chronotype and following an intermittent fasting schedule that best suits your individual needs.
Intermittent Fasting by Chronotype: Bears, Lions and Dolphins
Your chronotype is your body’s natural sleep pattern and it can provide important insights into your dietary needs. There are three primary chronotypes: Bears, Lions and Dolphins. Bears tend to be night owls and prefer to go to bed late and wake up late. Lions are early risers and prefer to go to bed early and wake up early. Dolphins are somewhere in between, tending to go to bed a bit earlier but still enjoy a later wake up time. Understanding your chronotype is essential for successful intermittent fasting.
Intermittent Fasting for Bears
The best intermittent fasting schedule for bears is a 16/8 plan with an 8-hour eating window between noon and 8 p.m. This schedule allows for plenty of time to rest and relax before hitting the hay and gives the body time to digest its food before beginning the fast. If you take on intermittent fasting but are picking a window that goes against your chronotype, not only are you less likely to stick to it, but you may also experience some unwanted side effects like feeling tired and sluggish during the day.
Intermittent Fasting for Lions
Lions, or early risers, thrive on a shorter eating window. The optimal intermittent fasting plan for lions is a 14/10 protocol, with a 10-hour eating window between 7 a.m. and 5 p.m. This plan allows for a longer fast and more time for your body to rest and recover. If you are a lion who has been struggling to get through a longer fast, this might be the perfect plan for you.
Intermittent Fasting for Dolphins
Dolphins are the middle ground between bears and lions. They tend to prefer a slightly longer eating window than lions but still benefit from intermittent fasting. The best intermittent fasting plan for dolphins is a 12/12 protocol, with a 12-hour eating window between 8 a.m. and 8 p.m. This plan allows for plenty of time to enjoy meals while still providing enough time for digestion and rest.
Adjusting Your Intermittent Fasting Schedule to Your Chronotype
Some trials show that specific diets adjusted to your chronotype are more effective in countering this tendency (1). If you’ve mustered up the courage to crush intermittent fasting, don’t be afraid to adjust your eating window to better suit your natural rhythms. When you learn your sleep chronotype, you can partner that with your body type to determine the length of your fast, producing a realistic view of when you should begin and end your eating window.
Intermittent Fasting Meal Plans by Chronotype
Bear: Eat breakfast at noon — a balance of carbs and protein. Have lunch at 4pm. Have dinner at 8pm.
Lion: Eat breakfast at 6:45am — high protein and healthy fat. Have lunch at 12:30pm. Have dinner at 5:30pm.
Dolphin: Eat breakfast at 8am — a balance of carbs and protein. Have lunch at 12pm. Have dinner at 7pm.
Intermittent fasting by chronotype is an effective way to boost your energy, improve your cognitive function, and improve your overall health. By understanding your chronotype and adjusting your eating window accordingly, you can set yourself up for success with intermittent fasting and enjoy the many benefits that come with it.
What is the practice of fasting at certain times of day based on one’s individual body clock?
A time-restricted diet involves eating within an 8- or 12-hour window, which is believed to boost metabolism and aid in weight loss. The optimal eating period for an individual is largely determined by their individual chronotype, or unique biological clock.
Which fasting schedule works best for those with a bear chronotype?
The best intermittent fasting plan for bears is an 16/8 approach with an 8-hour eating window between noon and 8 p.m. This plan provides optimal energy levels while allowing for a more traditional workday routine.
What are the benefits and risks of Lion intermittent fasting for people with a chronotype Lion profile?
Lion Chronotypes are individuals who tend to be most productive in the mornings, usually between 8 a.m. and 12 p.m. These individuals make up around 15% of the population and often find it difficult to stay focused and productive in the evening. Intermittent Fasting Plans are available to help Lion Chronotypes manage their meal times and energy levels.
Which intermittent fasting schedule is best for maintaining optimal health?
If you want to practice intermittent fasting, restrict the time of day when you eat to early hours, such as between 7 AM and 3 PM, or 10 AM and 6 PM. Avoid snacking or consuming any food after these times.
