What Is The 1: 8 Diet
The 16:8 diet is a form of intermittent fasting where you break the day into two parts: a 16-hour fasting period and an 8-hour period where you consume all your calories.
The 16:8 stems from the 8-Hour Diet book by author David Zinczenko and Peter Moore , former editor-in-chief of Men’s Health. The two created the plan off the back of the popular 5:2 diet, with the main difference being the longer fasting time between eating sessions. This, they say, gives the body the time it needs to process food and burn away extra fat.
The 8-Hour Diet by David Zinczenko and Peter Moore –
Suzie Sawyer , founder of Nutrition Lifestyle, says, “There are no restrictions on the types or amounts of food that a person can eat during the 8-hour window. This flexibility makes the plan relatively easy to follow.”
Intermittent Fasting The Best Diet For Type 2 Diabetes
Type 2 diabetes was once thought to be a chronic disease that could never be cured. You can start medications to control it, but those medications will be with you for life.
Now we know better. As Dr. Jason Fung has said, People are focused on giving drugs to type 2 diabetes, but it is a dietary disease.
He and his team at Intensive Dietary Management Program set out to prove that they can do better than drugs. They recently published a case report of three men with type 2 diabetes who were able to completely stop their insulin and most of the oral drugs while still improving their diabetes control.
How did they do it? Intermittent fasting.
The subjects fasted for 24 hours three to four days per week, going from dinner to dinner without food, while eating lunch and dinner on the other days. They lost between 10 and 18% body weight and between 10 and 22% from their waist circumferences.
But here is the amazing part.
Starting from a daily average of 70 units of insulin, they safely stopped their insulin as quickly as five days into the protocol, with the longest taking only 18 days. That is a dramatic result!
When done correctly, however, intermittent fasting combined with a low carb diet may be the best treatment of type 2 diabetes that we have ever seen.

Common Obstacles To Eating A Healthier Diet
Varady dabbles with intermittent fasting herself, typically for a few weeks after the holidays to lose a few pounds. The 16:8 plan is less intense than the other plans, but if she wants a more rapid weight loss, shell opt for alternate day fasting.
The first five fast days are pretty tricky, but once your body gets adjusted to that kind of up-down pattern of eating, it actually gets really easy, Varady told TODAY.
So how do you boost your chances of intermittent fasting success?

How Often Should You Do 1: 8 Intermittent Fasting
You can do anywhere from one day of intermittent 16:8 fasting to seven days a week, because, unlike other intermittent fasting diets, each day of the 16:8 works independently to the rest.
Evidence differs, however, on whether it’s healthy to do intermittent fasting all the time. While research from Queen’s Medical Centre has proven that short-term fasting boosts the metabolism, longer fasts of around three or more days can actually suppress it and slow it right down. Plus, going without food for a long period of time can lead to an increased level of cholesterol, feeling sick in the morning , dehydration and spells of low blood sugar.

May Reduce The Risk Of Cancer
Numerous animal studies suggest that intermittent fasting may reduce the risk of cancer. Such an effect may be the aftermath of weight loss, reduced inflammation, and insulin levels, which are caused by this eating pattern.
A 2019 review in people with cancer states that fasting reduced some of the side effects of chemotherapy and increased its effectiveness. The review suggests that fasting may deprive cancer cells of nutrients, making them more susceptible to the toxins in chemotherapy .
What Does Intermittent Fasting Do
The main benefits of intermittent fasting are weight loss and improving metabolic health, including better blood sugar control in type 2 diabetes.
There are different mechanisms to account for the success of intermittent fasting.
First, skipping meals and cutting out snacking naturally reduces the amount of calories one eats during the day. Thats why it is important to try not to eat more during your eating window to make up for the missed meal. That would negate one of the main benefits of fasting!
The second potential reason for IFs success is its ability to lower insulin levels. Studies show that fasting tends to lower insulin levels, although it is not scientifically clear the extent to which lower insulin levels can directly explain better weight loss.
However, a 2020 study from Dr. Ethan Weiss and colleagues created some doubt about whether short fasts of 16 hours, in the absence of any other dietary modification, can lead to improved weight loss and metabolic health. The studys authors concluded that time restricted eating was no better than eating throughout the day for weight loss.
We wrote about this study, noting that the fasting group did not reduce caloric intake, which puts it at odds with other studies that have suggested at least part of the benefit of fasting comes from reduced caloric intake.
But even though human data on longevity are lacking, the other benefits of IF and its ease of use likely make it worth a try.

Intermittent Fasting May Affect Men And Women Differently
There is some evidence that intermittent fasting may not be as beneficial for some women as it is for men.
One study showed that blood sugar control actually worsened in women after three weeks of intermittent fasting, which was not the case in men .
There are also many anecdotal stories of women who have experienced changes to their menstrual cycles after starting intermittent fasting.
Such shifts occur because female bodies are extremely sensitive to calorie restriction.
When calorie intake is low such as from fasting for too long or too frequently a small part of the brain called the hypothalamus is affected.
This can disrupt the secretion of gonadotropin-releasing hormone , a hormone that helps release two reproductive hormones: luteinizing hormone and follicle stimulating hormone (
For these reasons, women should consider a modified approach to intermittent fasting, such as shorter fasting periods and fewer fasting days.
Intermittent fasting may not be as beneficial for women as it is for men. To reduce any adverse effects, women should take a mild approach to fasting: shorter fasts and fewer fasting days.
Intermittent fasting not only benefits your waistline but may also lower your risk of developing a number of chronic diseases.

Benefits Of Intermittent Fasting
Can intermittent fasting improve your health? Recent research has found that using intermittent fasting for weight loss may have some benefits in the short term.
It appears that fasting for a short time can produce ketosis, which is a process that occurs when the body doesn’t have enough glucose for energy, so it breaks down stored fat instead. This causes an increase in substances called ketones. This, coupled with fewer calories consumed overall, can lead to weight loss. Research suggests that alternate-day fasting is about as effective as a typical low-calorie diet for weight loss.
Fasting also affects metabolic processes in the body that may work to decrease inflammation, as well as improve blood sugar regulation and physical stress response. Some research shows this may improve conditions associated with inflammation like arthritis, asthma and multiple sclerosis.
Little long-term research has been done on intermittent fasting to examine how it affects people over time. As a result, long-term health benefits or risks are unknown.
Frequently Asked Questions Concerns And Complaints
Im a woman. Should I do anything differently?
I havent worked with women on implementing an intermittent fasting schedule, so I cant speak from experience on this one.
That said, I have heard that women may find a wider window of eating to be more favorable when doing daily intermittent fasting. While men will typically fast for 16 hours and then eat for 8 hours, women may find better results by eating for 10 hours and fasting for 14 hours. The best advice I can give anyone, not just women, is to experiment and see what works best for you. Your body will give you signals. Follow what your body responds favorably to.
Also, if youre a female, there is an allfemale page on Facebook that discusses intermittent fasting. Im sure you could find a ton of great answers and support there.
I could never skip breakfast. How do you do it?
I dont. Breakfast foods are my favorite, so I just eat them at 1pm each day.
Also, if you eat a big dinner the night before, I think youll be surprised by how much energy you have in the morning. Most of the worries or concerns that people have about intermittent fasting are due to the fact that they have had it pounded into them by companies that they need to eat breakfast or they need to eat every three hours and so on. The science doesnt support it and neither do my personal experiences.
I thought you were supposed to eat every 3 hours?

How Much Weight Can You Lose On The : 8 Diet
If done so correctly, theres a typical weight loss of around seven to 11 pounds over a ten week period, according to a review of studies by Sydney Medical School . They found, on average, someone weighing 90kg would lose 5% of their body weight in 10 weeks.
But how much weight you lose on the 16:8 diet depends on eating fewer calories than youre burning. According to a leading study by the University of Vienna , this energy deficit can be achieved in many ways but is ultimately the only method of weight loss. When you eat food, your body metabolises it to create energy used for daily activities everything from breathing to walking around. If you have more energy than your body uses, the extra is mainly stored as fat. If you have less energy than what your body can burn, your body will turn to fat stores for energy. This is the calorie deficit.
While intermittent fasting has benefits, eating in a 8-hour period alone will not automatically mean you lose weight. The plan is just one way to achieve the deficit without having to count how many calories you burn in a day . The given eating time aims to automatically restrict the amount of food you can eat, leading to weight loss.
The Paleo Diet And Intermittent Fasting
Both the paleo diet and intermittent fasting harken to an era where humans lived as hunters and gatherers, eating as food was available versus three steady meals per day.
Intermittent fasting and the paleo diet work together in the following ways:
- Whilefasting promotes insulin sensitivity and low blood sugar, the paleo diet prevents these numbers from spiking once you eat again.
- Grains cause a predictable inflammatory response in many people, by avoiding them, you reap the benefits of reduced inflammation achieved by fasting.
- A paleo diet prevents hunger and cravings by putting an end to the insulin spike and subsequent crash triggered by high glycemic foods. This makes it easier to stick with your fast.
- The paleo diet can help ensure your nutritional needs are met during intermittent fasting by focusing on protein intake and a variety of nutrient-rich vegetables instead of grains.
