Ive Made The Decision To Fast So How Long Should I Fast For
There arent any studies right now that state exactly how long one should fast. Researchers, like Dr. Peterson, are working on that. The minimum amount of time it takes to make fasting efficacious hasnt been proven via study, but the prevailing notion is its somewhere between 12 and 18 hours. But it can take a few days sometimes weeks of fasting regularly for your body to start burning fat for fuel. Brooke Alpert, nutritionist and author of The Diet Detox, suggests starting by moving your last meal to around 7 p.m. She said the reason for this is our bodies are better at doing some things at certain times. Our bodies are better at processing sugar in the morning than at night, said Dr. Varady. So eat bigger meals in the morning, for example.
And how often do you have to do daily intermittent fasting to see the benefit? Again, there hasnt been a study thats shown exactly how many days you need to fast, but a recent study in rodents showed they get about the same benefits fasting five days per week as they did fasting every day. The great thing is that were learning is that this type of fasting isnt all or nothing, said Dr. Peterson.

Is 16/8 Intermittent Fasting Right For You
16/8 intermittent fasting can be a sustainable, safe and easy way to improve your health when paired with a nutritious diet and a healthy lifestyle.
However, it shouldnt be viewed as a substitute for a balanced, well-rounded diet rich in whole foods. Not to mention, you can still be healthy even if intermittent fasting doesnt work for you.
Though 16/8 intermittent fasting is generally considered safe for most healthy adults, you should talk to your doctor before giving it a try, especially if you have any underlying health conditions.
This is key if youre taking any medications or have diabetes, low blood pressure or a history of disordered eating.
Intermittent fasting is also not recommended for women who are trying to conceive or those who are pregnant or breastfeeding.
If you have any concerns or experience any adverse side effects while fasting, be sure to consult your doctor.
16/8 intermittent fasting involves eating only during an 8-hour window and fasting for the remaining 16 hours.
It may support weight loss and improve blood sugar, brain function and longevity.
Eat a healthy diet during your eating period and drink calorie-free beverages like water or unsweetened teas and coffee.
Its best to talk to your doctor before trying intermittent fasting, especially if you have any underlying health conditions.

So Is Intermittent Fasting As Good As It Sounds
I was very curious about this, so I asked the opinion of metabolic expert Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School. Here is what she told me. “There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally she recommends that people “use an eating approach that works for them and is sustainable to them.”
So, heres the deal. There is some good scientific evidence suggesting that circadian rhythm fasting, when combined with a healthy diet and lifestyle, can be a particularly effective approach to weight loss, especially for people at risk for diabetes.

How does intermittent fasting make you lose weight?
When you fast, you consume fewer calories than you normally do or no calories at all. As with the weight-loss basics go, the fewer calories you consume, the more weight you lose.
Intermittent fasting simply helps reduce your overall calorie intake. And this reduction in calorie intake is essentially what causes you to lose weight on IF.
But thats not all.
Fasting also causes several changes in the way your body stores and burns fat.
One is insulin.
Insulin is a hormone that converts your glucose, sugar into energy for fuel. Its a driver of your fat storage and its levels rise when you eat and decrease when you fast.
In short, fasting may drive fat loss, prevent additional fat storage, and result in weight loss.

So What Is Intermittent Fasting
Intermittent Fasting is an eating pattern where you cycle between periods of eating and fasting.Most of us already fast every day, while we are sleeping. Intermittent Fasting can be as simple as extending that fast for a few hours longer.However, if youre thinking about fasting as a long-term lifestyle change, you can choose from a number of Intermittent Fasting methods that are easy to implement into your daily routine.
Heres one example: Skip your breakfast and have your first meal at noon. Then have your last meal at 8 p.m. Thats it! Youll have fasted about 16 hours in a day, which would be the 16/8 method eating for 8 hours and fasting for 16 hours.Thats one of the most popular methods of fasting. Generally speaking, women should fast for about 13 to 14 hours a day. Men should fast up to 16 hours a day.One of the most important aspects of Intermittent Fasting is timing. In order to adjust the release of hormones in your body, its better to fast around the same time each day. This way, you will be able to ease your body into this new eating pattern and, of course, stick to the plan for the long term.
Why When You Eat Matters According To Scientific Research
In a study published in Obesity Journal, researchers randomized 93 overweight and obese women into two groups who ate the same foods. One group ate half their 1,400 daily calories for breakfast. The other group ate half their calories for dinner. While both groups lost weight, compared with the nighttime calorie group, the morning calorie group lost more weight, reduced their waist circumference by more, and lowered their fasting glucose and insulin levels by more.
Timing is everything when it comes to eating, Peeke says. We now realize that we spent so much time studying how much we eat, we never paid enough attention to when we eat.

Health Benefits Of Fasting
The big benefit of picking intermittent fasting for your nutrition plan is its so sustainable. With other diets youre either constantly counting calories, can only eat certain foods, or always cutting macronutrients. For example, the keto diet is quite effective for weight loss but the fact that you have to cut out your carbs forever isnt a sustainable diet for the majority of people . I mean imagine never being able to eat pizza, pasta, cookies, cereal, beer, wine, etc. ever again.
With intermittent fasting the big thing you have to be mindful of is to not eat during your fast. This is so simple anybody can follow it long term. But that doesnt always mean its easy. There are times when youre going to get hungry and tempted to eat. And then there are other times when social situations put you in a sticky position that practically force you to eat.
But lets say you go out with friends for dinner and end up eating and drinking until midnight. The good part with intermittent fasting is you just restart your fasting clock and wait a little longer to eat the next day. Its not like every other diet where you mess up by eating the wrong kind of food and then all your results go out the window.
So with intermittent fasting, you can keep your motivation going even if you have a little slip-up. If you ever have trouble with the hunger pangs during your fast then you could drink some of my approved fasting drinks:
- zero cal sparkling water
- water

How Do Fasting Diets Work To Help Rev Weight Loss
The idea behind intermittent fasting is that it increases your metabolic rate, which helps you burn more calories. And by restricting the time periods during the day when you eat, you take in fewer calories each day.
Going into diet change, I knew there was only early evidence that fasting can lead to temporary weight loss, and that more research is needed especially on the potential long-term health effects of this diet. As it stands, experts warn that fasting may not be safe, or smart, for everyone. Fasting is not recommended for some groups, such as pregnant or lactating women, some people with diabetes, people dealing with eating disorders or issues such as low blood sugar, according to the Mayo Clinic. Thats why experts stress that its important to consult your healthcare team before trying any type of fast.
Despite the lack of comprehensive research on intermittent fasting, this eating style has helped me lose weight, regain my energy, and become more mindful about my eating choices.

Isnt It Important To Have Breakfast Every Morning
Not necessarily. This appears to be an old misconception, based on speculation and statistics, and it does not hold up when its tested.57 Skipping your morning meal gives your body more time to burn fat for energy. Since hunger is lowest in the morning, it may be easiest to skip it and break your fast later in the day.58

Does Intermittent Fasting Work For Everyone
Varady and her colleagues hoped the review would help debunk some myths regarding intermittent fasting. Two such myths that intermittent fasting negatively affects metabolism, and that it causes disordered eating are not true, according to the studies reviewed. People are often concerned that fasting will make them feel lethargic and unable to concentrate, says Varady. Yet many people in these studies reported experiencing a boost of energy on fasting days, she says.
Although its different for each person, I would say that its a very small subset of patients who really notices improved mental clarity or energy with intermittent fasting, says Fatima Cody Stanford, MD, MPH, associate professor and obesity medicine physician scientist at Massachusetts General Hospital and Harvard Medical School in Boston, who was not involved in the review. Many people dont feel great while they are fasting for a variety of reasons. In some cases, their blood sugar might get too low during the fasting period, she says.
There are several groups who should not fast, according to the studies. Those individuals include:
- Those who are pregnant or lactating
- Children under 12
- Those with a history of disordered eating
- Those with a body mass index, or BMI, less than 18.5
- Shift workers, who studies have shown have difficulty with fasting regimens because of the changes in work schedules
- People who need to take medication with food at regimented times

Intermittent fasting is becoming a popular way to lose weight, with recipe collections, diet plans and apps dedicated to it. Research suggests that cycling between periods of fasting and eating may be able to help people manage their weight and health – and may even help to reduce the risk of diseases such as type 2 diabetes.

Why I Chose To Try Time
The definition of intermittent fasting is pretty basic. Its really just a period of eating, followed by a period of not eating, says Krista Varady, PhD, an associate professor in the department of kinesiology and nutrition at the University of Illinois in Chicago. For over a decade, Dr. Varady has researched the effects of intermittent fasting. Intermittent fasting is kind of an umbrella term, but there are three major types of intermittent fasting. Theres alternate-day fasting, which means that you would eat fewer than 500 calories every other day and eat however many calories you want on the remaining days of the week. Theres also whats called the 5:2 approach to intermittent fasting, which means you would eat fewer than 500 calories for two days per week and however many you want on the other days. And then theres whats called time-restricted eating, which means you can eat within a certain window of time each day, like between 10 a.m. and 6 p.m., says Varady.
Given that I was becoming more active through exercise, I wasnt sure that taking in only 500 calories a day would be the best idea for maintaining my energy levels. With that in mind, I decided to try time-restricted eating instead.

Wont Intermittent Fasting Burn Muscle
That depends on the person and the duration of the fast. During fasting, the body first breaks down glycogen into glucose for energy. After that, the body increases body fat breakdown to provide energy.
Excess amino acids are also used for energy, but the body does not burn its own muscle for fuel unless it has to.49
Some studies, however, suggest that leaner individuals are at higher risk of lean body mass loss, and even reduced metabolic rate. Yet it appears this is less of a concern with overweight subjects.50
In my experience with over 1,000 patients on various intermittent fasting regimens, I have not yet seen a single case of significant muscle loss.51Learn more

Is It Ok To Skip Breakfast
Yes, Varady said. The notion that omitting a morning meal is bad for your waistline likely began with studies sponsored by cereal companies, and most of that research looked at the effects of breakfast skipping on cognition in children, she noted: Im not sure how that all got translated to body weight.
