What is Intermittent Fasting and How does it Work
The term "intermittent fasting" refers to a type of eating plan in which the time between
meals is varied. Intermittent fasting has been shown to help with weight loss, disease
prevention, and reversal in some cases.
How, though, do you accomplish this feat? Is there any risk involved?
Simply Put
What is intermittent fasting?
Unlike other diets, which tend to center on what to eat, intermittent fasting is solely focused on how often you eat.
Following an intermittent fasting schedule means restricting your food intake to a single-time of day. Scientific studies suggest that one could improve one's health by skipping meals, fasting, or eating only one meal per day.
Mark Mattson, a neuroscientist at Johns Hopkins, has spent 25 years researching the effects of fasting cycles. He claims that we have the biological capability to fast for long periods of time (several days). Humans had evolved to survive and even thrive for long periods without food while they were hunters and gatherers in the past, before they discovered farming. Hunting game and gathering nuts and berries required a significant investment of time and effort, so they had no choice.
They say it was simpler to keep a healthy weight in the United States 50 years ago. People stopped eating at 11 p.m. because they went to bed and there were no computers or TV shows after that time. The portions were noticeably reduced. More people got out into the fresh air and did more physical activity as a result of working and playing outside.
Due to the accessibility of media, both adults and children are staying up later to engage in activities such as watching television, using the internet, playing video games, and chatting with friends online. That often entails a sedentary lifestyle, full of snacking well into the night.
A higher risk of developing obesity, type 2 diabetes, cardiovascular disease, and other diseases is associated with consuming more calories than one burns off in a given day and engaging in less physical activity. Intermittent fasting may help counteract these tendencies, according to the findings of recent scientific studies.
So...
What are the mechanics of intermittent fasting?
While there are many variations on intermittent fasting, they all revolve around setting specific eating and fasting windows. To lose weight, you could, for instance, try fasting for 16 hours every day and eating only during the first eight. Alternately, you could skip two meals on two different days of the week. Intermittent fasting can be done on a variety of timetables.
After several hours of not eating, the body starts burning fat instead of sugar, according to Mattson. That's what he calls "metabolic switching," by the way.
Most Americans eat continuously throughout the day, so "intermittent fasting" is a stark contrast to their typical eating pattern, as stated by Mattson. "If you eat three square meals and a couple of snacks every day but don't get any exercise, you're just putting the calories you consume each time to use as energy instead of burning off your fat reserves."
Intermittent fasting is effective because it increases the time between meals, allowing the body to burn more fat after the last meal has been digested.
The Plan
A daily strategy involves limiting your eating time to just six to eight hours once per day.
For instance, you could try 16:8 fasting, in which you eat every eight hours and go without food for the remaining 16.
Limiting your daily time window of eating does not prevent weight gain over time or yield significant weight loss results, according to one research study that was not designed specifically to look at an intermittent fasting pattern. The findings of that study suggested that limiting the frequency of large meals and increasing the frequency of smaller meals might help people maintain their weight or even lose weight over time.
The 5:2 method is another type of intermittent fasting in which you eat normally for five days out of seven. One meal of 500 to 600 calories on the other two days. To illustrate, let's say you've decided to restrict yourself to eating only once per day, every Monday
and Thursday, and that the other six days of the week you'll eat normally.
24-, 36-, 48-, and 72-hour fasts are not necessarily healthier than shorter fasts, and 72- hour fasts may be harmful. If you go without food for an extended period of time, your body may respond by storing more fat.
Based on his findings, Mattson concluded that it takes about two to four weeks for the body to adjust to intermittent fasting. Until you find your groove with the new schedule, you may experience some temporary discomfort, such as hunger or irritability.
However, he notes, study participants who make it through the adjustment period tend to stick to the plan because they feel better.
Can you recommend some foods that would be good to eat during my fasting periods?
Water and calorie-free drinks like black coffee and tea can be consumed between meals.
"Eating normally" does not refer to bingeing during your eating windows. High-calorie junk food, super-sized fried items, and treats are not likely to help you lose weight or improve your health, according to studies.
Some experts, however, praise intermittent fasting for facilitating the consumption of a wider variety of foods. The pleasure and health benefits of eating well are amplified when good food is shared with others and enjoyed in the context of a social gathering.
The Mediterranean diet is recommended by many nutritionists regardless of whether or not you are engaging in intermittent fasting. Greens, healthy fats, lean protein, and complex, unrefined carbohydrates like whole grains are safe bets when making dietary decisions.
Pros of Intermittent Fasting
Reducing your body fat
Intermittent fasting has been shown to have additional health benefits beyond just reducing body fat. According to Mattson, "when changes occur with this metabolic switch, it affects both the body and the brain."
When one of Mattson's studies was published in the New England Journal of Medicine, it provided evidence for a wide variety of health benefits linked to the practice. Longevity, weight loss, and mental acuity are just a few.
Fasting "protects organs against chronic diseases like type 2 diabetes, heart disease, age-related neurodegenerative disorders, even inflammatory bowel disease, and many cancers," he says.
Pros of Intermittent Fasting
Numerous advantages
So far, studies have shown the following advantages of intermittent fasting:
1. Memory and thinking. According to research, intermittent fasting improves working memory in animals and verbal memory in adults.
2. Cardiovascular health. Intermittent fasting increased blood pressure, resting heart rate, and other heart-related measurements.
3. Physical ability. Fasting for 16 hours resulted in fat loss while maintaining muscle mass in young men. Mice fed on alternate days had greater endurance when running
4.Obesity and type 2 diabetes. Intermittent fasting prevented obesity in animal studies. In six brief studies, obese adult humans lost weight by fasting intermittently. People with type 2 diabetes may benefit from the following:
The majority of available research indicates that intermittent fasting can help people lose body weight and lower their fasting glucose, fasting insulin, and leptin levels while also reducing insulin resistance, decreasing leptin levels, and increasing adiponectin levels. According to some studies, some patients who practiced intermittent fasting under the supervision of their doctors were able to eliminate their need for insulin therapy.
5. Tissue well-being. Intermittent fasting reduced tissue damage and improved surgical outcomes in animals.
Is intermittent fasting safe?
Some people try intermittent fasting to lose weight, while others use it to treat chronic conditions like irritable bowel syndrome, high cholesterol, or arthritis.
However, intermittent fasting is not suitable for everyone.
1. Children and teenagers under the age of 18.
2. Women who are pregnant or nursing.
3. People who have type 1 diabetes and use insulin. While a growing number of clinical trials have shown that intermittent fasting is safe in people with type 2 diabetes, no studies in people with type I diabetes have been conducted.
4. Those who have had an eating disorder in the past.
Keep in mind that the effects of intermittent fasting could vary from person to person. Make an appointment with your doctor if you experience any strange symptoms after beginning intermittent fasting, such as increased anxiety, headaches, nausea, or other digestive issues.
