When Should I Exercise
When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
What Is 1: 8 Intermittent Fasting
The 16:8 fasting plan is an eating schedule in which you fast for 16 hours each day and eat during an eight-hour window.
This eating schedule comes with all the benefits of other fasting schedules . Perhaps even better, you pick the eating window.
So what should that eating window be? “There’s actually infinite variability. It can be any time. Any time that you don’t eatthat’s fasting,” explains Jason Fung, M.D., fasting expert and author of the book The Complete Guide to Fasting.
If you can’t live without breakfast, slot your food earlier in the day .
If you prefer an early dinner, eat in the middle of the day .
If you’re someone who regularly goes out with friends for late dinners, schedule your eating hours later in the day .
Contrary to popular opinion, there are no rules around how many meals you have to squeeze in or whether or not you have to include breakfast. In fact, no data actually proves breakfast makes you healthier or weigh less.
Intermittent Fasting And Weight Loss
Data shows diets dont work. Theyre unsustainable in the long run and not that useful for weight loss. Yes, youll lose a few pounds initially, but research shows those changes dont last. Intermittent fasting is a fantastic alternative. Since IF is a lifestyle transformation, its more sustainable than any fad diet that tempts you.
Many research studies confirm IF is a sustainable weight-loss method and a valid option if weight loss is your goal. One 2018 study shows IF is also beneficial because it can help you lose weight without focusing on calorie counting an added benefit if you dont want to work that hard.

How Do I Manage My Hunger On If
Hunger is inevitable, but mild hunger is something you can definitely manage. Try sipping on calorie-free beverages like green tea or coffee, chewing on sugar-free gum, or good old-fashioned distraction.
After a while, your body should adjust to your eating window and youll feel less hungry during your fasting window.
HOWEVER, if you start to feel other symptoms beyond a gnawing at your stomach , dont be an IF hero eat!!
Is 1: 8 Fasting Good For Weight Loss
Some studies have found that theres virtually no difference between people who regularly practiced intermittent fasting and those who simply cut back their calorie intake overall.
A growing body of research demonstrates that a better strategy is optimizing the nutritional quality of what you already eat versus fasting or counting calories. Also, science suggests any potential benefit from fasting is quickly undone during the eating part of the cycle, in which appetite-suppressing hormones switch gears to make you feel even hungrierthan you felt at baseline.
But some dieters may benefit from daily fasting if they have trouble sticking to prescribed meal plans or restrictive diets a 2018 pilot study published in the Journal of Nutrition and Healthy Eating suggests that a 16:8 fasting plan can help obese dieters lose weight without having to count every single calorie they eat. This approach to fasting could also aid those battling other weight-related issues namely, high blood pressure. A new scholarly review published in the New England Journal of Medicinesuggests that a 16:8 fasting plan may help the body naturally improve blood sugar regulation, as well as decrease blood pressure overall in the long run.

When To Eat Carbs On Intermittent Fasting
Since no essential carbohydrates exist, the body does not need them to survive. However, our body cannot produce essential fatty acids and amino acids.
But because it can produce glucose through gluconeogenesis, blood sugar levels remain stable if you eat zero carbs .
Nevertheless, there are situations with intermittent fasting where carbohydrates can fit well into the diet.
For example, many athletes do not want to do without carbohydrates, as they continuously empty their glycogen stores. Adding carbohydrates to their diet can contribute to muscle recovery .
Thus, you can time carbohydrates very well during intermittent fasting:
- Training day: More carbohydrates replenishing glycogen stores in the muscles
- Rest day: low-carb or ketogenic diet
Accordingly, you can adapt your intermittent fasting plan to athletic needs through carb-cycling or cyclical ketogenic nutrition.
Nevertheless, so-called loading days are not necessary for muscle building as long as the protein supply is given .
Although the insulin levels increased by carbohydrates can help the muscles recover, it also helps build body fat more efficiently .
For this reason, bodybuilders often claim that they cant gain muscle without also building up body fat.
In short, a low carbohydrate ketogenic diet is still the best option if losing weight is your primary goal.
Intermittent Fasting Type Also Aids Weight And Fat Loss
As we have mentioned, one of the primary 16:8 fasting benefits includes your bodyâs ability to burn fat mass for fuel. This eliminates fat stores in the body, helping you permanently lose pounds through calorie restriction and eating periods, as well as preventing future weight gain.
Instead of just losing water weight, intermittent fasting and ketosis directly target fat build-ups in your body for lasting results.

How The 16/8 Intermittent Fasting Diet Works
Like exercise, restricting calories is a helpful metabolic stressor. Eating within a certain time frame pushes your body in a different metabolic direction than if you were eating all the time.
Intermittent fasting can cause autophagy, which is a crucial defense mechanism against malignancy, infection, and neurodegenerative diseases. Its basically your bodys way of cleaning out cells that arent performing at their best.
Research finds short-term fasting is an effective way of starting neuronal autophagy , therefore protecting your brain against neurodegenerative diseases.
Intermittent fasting also triggers a beneficial metabolic reaction that includes:
- A decrease in inflammatory markers
- Reduced blood glucose levels and insulin
- An increase in the neurotrophin BDNF
These are powerful changes that can lead to several health improvements.

The Benefits Of Intermittent Fasting
Fat loss is great, but it isn’t the only benefit of fasting.
1. Intermittent fasting makes your day simpler.
I’m big on behavior change, simplicity, and reducing stress. Intermittent fasting provides additional simplicity to my life that I really enjoy. When I wake up, I don’t worry about breakfast. I just grab a glass of water and start my day.
I enjoy eating and I don’t mind cooking, so eating three meals a day was never a hassle for me. However, intermittent fasting allows me to eat one less meal, which also means planning one less meal, cooking one less meal, and stressing about one less meal. It makes life a bit simpler and I like that.
2. Intermittent fasting helps you live longer.
Scientists have long known that restricting calories is a way of lengthening life. From a logical standpoint, this makes sense. When youre starving, your body finds ways to extend your life.
Theres just one problem: who wants to starve themselves in the name of living longer?
I dont know about you, but Im interested in enjoying a long life. Starving myself doesnt sound that appetizing.
The good news is that intermittent fasting activates many of the same mechanisms for extending life as calorie restriction. In other words, you get the benefits of a longer life without the hassle of starving.
Way back in 1945 it was discovered that intermittent fasting extended life in mice. More recently, this study found that alternate day intermittent fasting led to longer lifespans.

If youve decided you want to follow a 16:8 intermittent fasting style pattern, or any style of intermittent fasting, ensure its safe to do so by talking first to a health professional, such as a GP, dietitian or registered or associate nutritionist, says Nigel Denby, dietitian and founder of Harley Street At Home .
I wouldnt advise the following to take part in intermittent fasting: anyone with a history of disordered eating or an eating disorder, underweight people, children or adolescents, pregnant or breastfeeding women or those with a medical condition.Intermittent fasting for women in general may require a different approach to that of men.

Induced Autophagy May Be Also Linked With The 1: 8 Intermittent Fasting Type
Autophagy is the stage of fasting and ketosis in which the body can essentially repair itself. While in autophagy, your body detoxes itself, purging excessive stress hormone levels, damaged cells, and unhealthy tissue, rejuvenating your entire system on a molecular level.
After being in a calorie deficit for many hours, your metabolism has the opportunity to start the autophagy process and heal itself from the inside out.
We Fasted 2 Days A Week Heres What Happened
Fasting just one day a week worked great for Precision Nutritions co-founder, John Berardi, PhD. Sure, on that first day without food? Hunger dogged him. His family also reported that he was quite crabby.
But he adapted. And with an eat anything day once a week to counteract his eat nothing day, everything felt doable. After roughly five weeks of fasting, I was barely uncomfortable at all, says Dr. Berardi. And by my seventh or eighth fast, I was having great days.
Dr. Berardi lost 12 pounds of body weight during the first eight weeks on this schedule.
Dr. Scott-Dixon? She had similar experiences.
But when they both tried to add a second fasting day? Everything went sideways.
Within two weeks, Dr. Berardis morning weight plummeted from 178 pounds to 171, with an estimated 4 additional pounds of fat lost but he lost 3 pounds of lean mass, too.
He felt small and weak, and was losing too much weight too fast.
People commented on how drawn and depleted Dr. Berardi looked. And he was exhausted. Training became a struggle. Even getting off the couch was a struggle.
Dr. Scott-Dixon had a similar experience.
In particular, people commented on how awful my face looked, she says. Family members worried that I had a terminal disease.
The lesson:When it comes to fasting, do just barely enough to meet your goals.
And maybe even a little bit less than you think you need.

What To Eat During Intermittent Fasting 16/8
Though intermittent fasting isnt a diet in the sense that there are food-specific restrictions imposed, it is recommended that you eat as many whole foods as possible and avoid processed foods. The quality and nutritional value of food matters greatly when practicing any kind of health plan, advises Wandzilak.
According to Grant, what you choose to eat will depend on your goals. When doing any type of fast, water is the most common beverage to consume during your fasting period. However, if you’re looking for a lifestyle rebootor if your goal is weight losscoffee or tea is acceptable during fasting periods as well.

If gut rest is your ultimate goal with fasting, then no food or beverages, aside from water, should be consumed during a fast, explains Grant. However, if longevity, weight loss or metabolic benefits are your goal, then sometimes a few calories, such as plain coffee or tea, can be consumed during your fasting period without having much of a negative impact on the outcomes.
Most experts agree that standard diet recommendations are also encouraged when intermittent fasting, though Grant specifies that prioritizing protein during your first meal of the day can help your body as it rebuilds and repairs as it prepares to once again enter the digestion phase.
Psychological Advantages Of Intermittent Fasting
Intermittent fasting is more of a lifestyle than a diet.
Diets are eating patterns we follow for a short period of time. They often require considerable willpower, which is why they have such an incredibly low success rate.
On a traditional diet, each time you eat, you face a decision about whether to eat what you should eat or to eat what you feel like eating.
With intermittent fasting, theres no decision to be made about what to eat when youre most likely to make a poor decision. You just dont eat.
Researchers have found this to be the case as well. Adherence to intermittent fasting is much better than other diets.
Try it tomorrow morning. When you walk into your kitchen at your usual breakfast time, instead of asking, What should I eat for breakfast? simply say out loud, I dont eat breakfast.
Eliminate the opportunity to be tempted, and you save yourself from making a poor decision.

Are There Any Risks
Intermittent fasting is not safe for some people, including people who are pregnant, children, people at risk for hypoglycemia or people with certain chronic diseases.
If youre at risk for an eating disorder, you shouldnt attempt any sort of fasting diet, advises Taylor. Intermittent fasting has also been known to increase the likelihood of binge eating in some people because of the restriction.
If youre interested in trying intermittent fasting, you should also be aware of some not-so-pretty side effects. It can be associated with irritability, low energy, persistent hunger, temperature sensitivity, and poor work and activity performance.
Ultimately, you should contact your healthcare provider and discuss these options. They know your health better than anyone else and can offer the right guidance on whether or not any of these intermittent fasting options are right for you.
How Can You Start The 1: 8 Intermittent Fasting Schedule

Put simply, on this plan, you will fast for 16 hours, leaving you with 8 hours to get your meals in. And while that might sound terrifying at first glance, it actually isnt nearly as dreadful as you think.
In fact, a 16:8 intermittent fasting schedule provides the perfect window to get in all of your much-needed nutrients while still giving your body a break to properly digest it all.
And to put you at further ease, you will actually be sleeping through half of your fasting period anyways.
So, say goodbye to those Tum Tums and that 24-pack of ginger ale because most of your bellyaches and digestive issues will cease to exist in just a couple of weeks or so.

How To Get Started 16/8 Intermittent Fasting
16/8 intermittent fasting is simple, safe, and surprisingly easy to get started with.
Just pick an 8-hour feeding window, eat 1-3 nourishing meals within that window, and abstain from anything except coffee and water the rest of the time.
The most popular 8-hour window is 12 pm to 8 pm. That said, 16/8 fasting is highly flexible.
You can structure it around your work schedule, workout schedule, or family time. You can eat from 12-8 on weekdays and switch things up to 8-4 or 2-10 on the weekends.
Others opt to eat between 9 am and 5 pm, which allows them to have a more standard breakfast, lunch, and early dinner. This type of circadian eating is thought to be good for digestion.
IF becomes even easier if you already skip breakfast. Youll just need to refrain from snacking or drinking calorie-containing beverages outside of your preferred 8-hour window.
Most people find that their body adjusts to 16/8 fasting within a few days, after which the fast becomes surprisingly hunger-free.
Filling up on superfoods during your eating window can boost satiety enough to make your daily fast even easier. Consider including a nice balance of animal-based fats and proteins in each meal.
