Intermittent fasting is a well-known technique used by many professionals. Some of these people include Gwyneth Paltrow, Tim Ferriss, and Richard Branson. If followed correctly, fasting can help you become leaner, stronger, healthier, and significantly fitter than ever before. There are different types of intermittent fasting depending on how often the fasts occur with differing benefits
Intermittent fasting is a dieting method that allows people to eat whatever they want, whenever they want. It’s also known as the “5:2 diet.” There are 3 different types of intermittent fasting. The first one is called “The 16/8 Diet,” and it’s where you only fast for 16 hours a day, and then you eat within 8 hours. The second type is called “The 5:2 Diet,” and it’s where you only fast for 2 days a week, and then you eat within 24 hours on your non-fasting days. The third type is called “The Eat Stop Eat Diet,” which is when you stop eating after an hour or two of having your last meal in order to force yourself into ketosis.
Imagine being able to eat anything you want most days of the week and still losing weight by restricting your consumption for one or two days at a time. Intermittent fasting, believe it or not, is beneficial and helps to normalize blood sugar levels, decrease inflammation, and keep your heart healthy.
Intermittent fasting may be done in a number of ways, and several research back up the numerous health and wellbeing advantages.
Intermittent fasting (IMF) may be a simple strategy to enhance your health while also achieving your weight reduction objectives, ranging from fasting for a few hours each day to missing meals two days a week.
Intermittent Fasting and How It Works
Intermittent fasting, also known as cyclic fasting, has been more popular in recent years as fresh research uncovers additional intermittent fasting advantages.
The authors of a paper published in Cell Metabolism in 2016 titled “Fasting, Circadian Rhythms, and Time-Restricted Feeding in Healthy Lifespan” highlight how fasting allows people to depend less on glucose reserves and more on ketone bodies and fat stores for energy. As a consequence, “both intermittent and periodic fasting have health advantages ranging from illness prevention to improved therapy.” Even while fasting mimicking diets (FMDs) are not actual fasting, they may produce positive effects comparable to those seen during fasting.
Intermittent fasting, on the other hand, is not a novel notion. It’s been utilized for millennia in times of scarcity of food, and it’s even a prominent figure in many major faiths. In truth, Muslims celebrate Ramadan, a month of fasting from sunrise to sunset, once a year.
It’s tough to describe intermittent fasting since there isn’t a single right way to fast. In reality, there are several variants of intermittent fasting practised all around the globe. Each has a distinct eating pattern that is frequently followed religiously in order to accomplish physical or even spiritual goals.
What is the mechanism behind it? Intermittent fasting seems to work in two ways to enhance separate aspects of health, according to comprehensive study. Intermittent fasting, for starters, reduces oxidative stress in cells all throughout the body.
Fasting, on the other hand, boosts your body’s capacity to cope with stress at the molecular level. Intermittent fasting stimulates your body’s stress response by activating cellular stress response pathways in the same manner as extremely mild stressors do. As this happens on a regular basis, your body becomes more resistant to cellular stress and hence less prone to cellular aging and disease development.
The most prevalent varieties of intermittent fasting, sometimes known as fasting diets, include:
- Fasting every other day is known as alternate-day fasting. On fasting days, some people eat nothing and others consume a tiny quantity of food, usually about 500 calories. Eat regularly (but healthily!) on non-fasting calorie days.
- The Warrior Diet entails eating solely fruits and vegetables throughout the day and one huge meal at night.
- 16/8 Fasting (also known as Time-Restricted Feeding): This strategy involves fasting for 16 hours a day and eating for just eight hours. The most common method is to miss breakfast the following morning and not eat anything after supper.
- Eat-Stop-Eat: Try the “Eat Stop Eat” strategy by fasting for 24 hours one or two days a week and then eating nothing from supper one day to dinner the following. On the other days, you should consume a typical amount of calories.
- 5:2 Diet: You eat regularly on five days of the week. You should limit your caloric intake to 500–600 calories per day for the next two fast days.
1. Assists in weight loss
One of the most significant advantages of intermittent fasting is increasing fat burning and aiding weight loss. In fact, many individuals prefer intermittent fasting over standard diets since it eliminates the need to measure meals and keep track of calories and grams ingested.
By pushing your body to utilize fat storage as fuel, IMF leads in greater fat burning and rapid weight reduction. When you eat, your body burns glucose (sugar) for energy and stores the rest as glycogen in your muscles and liver.
When your body is deprived of a continuous supply of glucose, it starts to break down glycogen for fuel. When glycogen is exhausted, your body looks for additional sources of energy, such as fat cells, which subsequently break down to provide energy.
This is comparable to the ketogenic diet (sometimes known as the “keto diet”), which involves depriving your body of carbs and forcing it to rely on stored fat for energy.
A 2015 evaluation of the effects of alternate-day fasting on body composition found that it reduced body weight by up to 7% and body fat by up to 12 pounds on average. Fasting during the whole day had comparable outcomes, but with a 9% drop in body weight. It’s unclear what happens to your important muscle reserves if you fast for the whole day.
Another research found that the 16/8 strategy of intermittent fasting dramatically decreased fat mass while maintaining muscle mass and strength. For this reason, I most often advocate this kind of intermittent fasting.
2. Lowers blood sugar levels
Carbohydrates are turned down into glucose (sugar) in your bloodstream when you consume. Insulin is the hormone responsible for transferring glucose from the circulation to the cells, where it may be utilized for energy.
When you have diabetes, your insulin may not continuously operate properly, resulting in high blood sugar levels and symptoms such as tiredness, thirst, and frequent urination.
Intermittent fasting has been shown in certain trials to enhance blood sugar levels by keeping them stable and minimizing spikes and crashes.
Participants with diabetes fasted for an average of 16 hours each day for two weeks in one research. Intermittent fasting resulted in weight loss, reduced calorie intake, and a substantial reduction in blood sugar levels.
According to another research, fasting reduced blood sugar by 12% and insulin levels by almost 53%. This is because insulin can act more effectively if it isn’t allowed to build up, and your body is more sensitive to its effects if it isn’t allowed to build up.
3. Maintains the health of your heart
One of the most remarkable effects of intermittent fasting is its positive impact on heart health. Studies have shown intermittent fasting to promote heart health by decreasing specific heart disease risk factors.
Fasting was shown to affect numerous aspects of heart health in one research. For example, it raised levels of healthy HDL cholesterol while lowering levels of harmful LDL cholesterol and triglycerides.
Intermittent fasting generated an increase in adiponectin levels in one animal research published in the Journal of Nutritional Biochemistry. Adiponectin is a protein involved in fat and sugar metabolism that has been linked to a reduced risk of heart disease and heart attacks.
In one research, mice that fasted every other day were almost 66 percent more likely than those on a regular diet to survive a heart attack.
4. Assists in the reduction of inflammation
Inflammation is the body’s natural reaction to harm. Chronic inflammation, on the other hand, may result in long-term health problems. Certain studies have related Inflammation to heart disease, diabetes, obesity, and cancer.
A research published in Nutrition Research examined 50 people who fasted throughout Ramadan and found that they had lower levels of several inflammatory markers. A 2015 research revealed that a longer period of nocturnal fasting was linked to lower levels of inflammatory markers. Alternate-day fasting was shown to help lower oxidative stress indicators in the journal Rejuvenation Research.
While additional study is required, these results demonstrate that IMF may aid in the reduction of inflammation and the prevention of chronic illness.
5. It protects your brain
Intermittent fasting has been shown in certain studies to safeguard the health of your brain, in addition to keeping your heart healthy and warding off illness.
When compared to a control group, an animal research found that intermittent fasting improves cognitive performance and protects against alterations in memory and learning ability. According to another animal research, intermittent fasting preserves mice’s brains by altering proteins involved in brain aging.
Intermittent fasting’s anti-inflammatory properties may potentially aid reduce the course of neurological diseases like Alzheimer’s disease.
Fasting is also said to stimulate autophagy, or “self-eating,” which is our natural body process of cellular regeneration — a process that is allegedly accelerated by fasting, but more scientific data is required to be sure.
6. Reduces Hunger
The satiety hormone, commonly known as leptin, is a hormone generated by fat cells that helps communicate when it’s time to quit eating. When you’re hungry, your leptin levels decrease, and when you’re full, they rise.
Because leptin is created in fat cells, people who are overweight or obese have more leptin circulating in their bodies. Too much leptin, on the other hand, may create leptin resistance, making it more difficult for it to successfully turn off hunger impulses.
Leptin levels were tested during intermittent fasting in a research with 80 individuals, and levels were shown to be lower at night throughout the fasting phase.
Lower leptin levels might mean less resistance to leptin, less hunger, and perhaps even greater weight loss.
Most Effective Intermittent Fasting Method
As previously said, there are many different varieties of IMF with various alternatives to match any schedule or lifestyle. It’s wise to try a few different things until you discover one that works best for you.
The intermittent fasting 16/8 technique, a kind of time-restricted eating, is the best place to start for novices. This usually entails foregoing your evening snack after supper, as well as missing breakfast the following morning.
You’ve already fasted for 16 hours if you don’t eat anything between 8 p.m. and 12 p.m. the following day.
It’s important to remember that intermittent fasting is more of a lifestyle shift than a diet. Unlike traditional diets, there’s no need to track points or calories or keep a meal journal every night.
To get the most out of intermittent fasting, be sure to concentrate on filling your diet with nutritious whole foods on the days you do eat. This will help you get the most nutrition out of your day.
Also, constantly pay attention to your body. If you feel weak or tired after going a whole day without eating, consider boosting your intake and having a small meal or snack. Alternately, try one of the other intermittent fasting approaches to see what works best for you.
Although intermittent fasting has several health advantages, it may not be appropriate for everyone, and some individuals may want to avoid it.
If you have low blood sugar, going without food for a whole day may cause hazardous reductions in blood sugar, resulting in symptoms such as shakiness, heart palpitations, and weariness. Whether you have diabetes, see your doctor to see if intermittent fasting is a good option for you.
This may not be suitable for you if you have a history of eating problems since it may promote harmful habits and provoke symptoms. Intermittent fasting is not suggested for children or teenagers who are still developing.
Those who are unwell should think twice about intermittent fasting since it deprives your body of the constant supply of nutrients it needs to heal and recover.
Is it possible for women to fast intermittently? Those who are pregnant, of course, should avoid intermittent fasting and instead concentrate on a healthy, vitamin- and mineral-rich diet. And some women may have hormone troubles if they fast for days on end; they may benefit from intermittent fasting just a few days a week rather than every day, for example.
Fasting should also be avoided if you have gallstone disease since it might raise the risk of gallbladder troubles.
Finally, research demonstrates that fasting may affect thyroid hormone levels. Therefore, if you have thyroid problems, you should try intermittent fasting to prevent changes in these vital hormones.
Intermittent fasting and working out are OK if you’re physically active. While you may workout on fast days, don’t overdo it, and be sure to drink lots of water. However, if you’re fasting for more than 72 hours, you should minimize your physical activity.
- Intermittent fasting may be suitable for you if you’re seeking for a technique to boost fat burning and weight reduction while also reaping some additional general health advantages.
- Fasting may help you lose weight and burn fat while also managing your blood sugar, preserving your brain, keeping your heart healthy, and lowering inflammation.
- Intermittent fasting comes in a variety of forms, with modifications that may fit into any lifestyle.
- Intermittent fasting may not be suitable for everyone, particularly those with specific medical issues. However, it may be a great complement to an otherwise healthy lifestyle for many individuals.
