Adapting to a new eating window routine -
But which time frame works best depends on the individual. Intermittent fasting is a dietary routine that regularly alternates between periods of eating and fasting. There are many different methods of doing so, with many requiring you to fast for 12—40 hours at a time.
Researchers have already linked numerous health benefits with intermittent fasting and continue to examine them. Plus, for some people, intermittent fasting fits well into their model of a healthy and sustainable long-term diet.
Two main reasons why people try intermittent fasting are to manage their weight and metabolic health. Metabolic health is a marker of how well the body processes, or metabolizes, energy. Fasting or abstaining from food can create a calorie deficit, meaning that your body has fewer calories than it needs to maintain its current weight.
Research shows that some types of intermittent fasting can be as effective for weight loss — though not necessarily more effective — as other diets that also rely on limiting your daily calorie intake 6 , 7 , 8 , 9.
Alternate-day fasting and the diet may also be effective 10 , 11 , 12 , Besides naturally eliminating your calorie intake during the fasting period, intermittent fasting may support weight loss by regulating your appetite to increase feelings of fullness while suppressing feelings of hunger 14 , 15 , Intermittent fasting might sound complicated and intimidating, but it can be simple at times.
In fact, you might even find that fasting helps simplify your day since you need to plan fewer meals. For example, having an early dinner followed by a late breakfast the next day is one way to fast intermittently.
If you finish your last meal at 8 p. However, other people instinctively eat this way already. They may be more prone to trying out an intermittent fasting eating pattern.
For example, intermittent fasting might work particularly well for someone who wants to pair it with a resistance training program and a high protein diet Intermittent fasting is often used to manage weight and metabolic health.
The eating routine might help lower blood pressure, blood sugar, and blood fat levels. For some people, it also works as part of a healthy long-term diet pattern. Intermittent fasting is one way to regulate your calorie intake and work toward improving your metabolic health.
Though the eating pattern can certainly be part of a healthy diet, it will likely take some adjusting to in the beginning. Plus, simply put, intermittent fasting is not right for everyone. For some people, using those tactics to keep your calorie intake within a designated time frame is no problem, but for others, it might feel unnatural at first.
Further, if you prefer not to follow a strict schedule, you might find intermittent fasting frustrating. You may go to bed hungry several times per week. That may naturally feel unpleasant and unsustainable in the long term Plus, at times, it might be necessary to override your natural hunger and fullness cues in order to not break your fast earlier than planned.
Many people adjust to the routine, and some even find they enjoy it after a few months. Yet, hunger and frustration are certainly something to expect and be aware of initially. When you first try intermittent fasting, one of the first things you may notice — aside from feeling more hungry — is ups and downs in your mood.
This is understandable. Besides initially increasing hunger levels, fasting can have side effects, including headaches, constipation, fatigue, sleep disturbances, and more 15 , 27 , 28 , This is a common bodily response to fasting or restricting calories 30 , 31 , Still, like hunger, your emotional well-being may be another side effect of intermittent fasting that will improve with time and practice Especially in the beginning, intermittent fasting can have side effects like hunger, headaches, and fatigue.
The combination of low blood sugar levels from fasting and the stress of adjusting to a new routine could affect your mood and mental health, too. This method has been linked to weight loss, although there is not enough evidence to show is is better than any other method for losing weight.
Many people fast for a hour period, say, from 8. This type of fast can help you avoid late night snacking. A fast can last from 12 to 40 or more hours. It is best to start with 12 hours and only take on a longer fast under medical supervision or after speaking with a doctor. Intermittent fasting is a weight loss tool that works for some people, but not everyone.
It may also be unsuitable for children, people with underlying health conditions, and people who are pregnant or breastfeeding. If you decide to try intermittent fasting, remember that just like with any eating pattern, diet quality is key. To gain the most from intermittent fasting, be sure to eat a variety of nutrient-dense whole foods during your eating window and limit ultra-processed foods.

VIEW ALL HISTORY. Intermittent fasting is a very popular health and fitness trend. It involves eating patterns that cycle between periods of eating and fasting. Before you try intermittent fasting, it's only natural to want to know whether it can help you achieve your goals.
This article tells you whether…. If you're unsure which of many diet plans is most effective for you, it can be hard to start your weight loss journey. Yes, it is okay to move your fasting window.
Being as busy as we are, moving around the hours of time-restricted eating isn't difficult, nor does it cause problems.
A variation in your fasting schedule is fine as long as you are eating well, consuming healthy foods like healthy fats, eggs, veggies, nuts, avocados, and more as described in my post on clean eating.
Remember, your food intake, meaning what you eat in your eating window is just as important as when and how long your fasting window is. Sure, ketosis your body switches from using glycogen to ketones is essential to autophagy, when the body cleans out old cells and replaces them with new ones, but what you eat in your "fed state" is crucial to intermittent fasting success too.
If you need to move your fasting window for work scheduling or because the kids' soccer game time changed, that's okay. This scenario really works with the knowledge that our bodies are adaptable.
Think of what our bodies do for us each and every day! To do this simple Intermittent Fasting move, simply make a shift. If you are used to fasting from 7 pm to 11 am but have had say, a change in your work schedule and now need to eat earlier, just make a simple change.
Change the start of your fasting window at night to 5 pm if it used to be 7 pm for example and end it at 9 am rather than the later 11 am. If you were extending your fasting window to a longer one, perhaps from 12 hours to 14 hours, then yes, I would say make the change gradually by adding a chunk of minutes to your fasting window every day to extend it from 12 to 14 hours slowly.
Moving your fasting window is like moving your run time. This is all about optimizing your eating window to your new routine. Studies back the fact that counting your macros is a good thing for optimum health and doing so is also a bonus when moving your fasting window.
This scenario works well in the case of big changes, like moving across time zones or any other scenario when you need to move your fasting window 4 to 5 hours. Eat when your body requires it.
Doing so will give you the energy and nutrients to get you through these big changes. Once your circadian rhythm adjusts, you can get the eating and fasting windows back on track with your new requirements. Lengthen your non-eating period bit by bit. The goal is to keep eating healthy. With my IF lifestyle, I like to take cues from my body as to what I should eat.
It's important to keep eating well when you move your fasting window. You want to feel well even with the alterations in your eating schedule. I have a video on what I eat in a day and why it works for me. With these foods and IF, you'll see fat loss, improvements in lean muscle mass, and better digestion.
And inflammation? No worries there! You'll feel better with Intermittent Fasting. The healthiest way to fast is to take care of yourself first and make sure you feel good.
Whether you are new to fasting or someone who has been enjoying the benefits of fasting for a while, there are things you should always remember.

However, based on what we just described about the circadian rhythm, you are probably not reaping all of the benefits this diet can offer you. If you are changing times by going outside of your window by a small amount, maybe a half hour or less, or if you go way outside your window every once in a while, you are probably fine.

Saeed notes that men and women may experience weight loss differently, though. Pelz says after 18 hours in a fasted state, your body will experience a wide array of positive short-term benefits like enhanced mental clarity and cognitive function 9.
Fasting is also being researched as a preventive tool against cognitive decline and disorders like dementia and fasting reduces those conditions," Jason Fung, M.
Fasting especially when paired with a keto eating pattern can also stimulate ketone production, which has been shown to boost neural metabolism 11 , giving you more energy and mental clarity, Pelz says.
Saeed shares that IF has also been shown to affect the growth hormone brain-derived neurotrophic factor BDNF 12 , which plays a role in stimulating new brain cells and the boosting performance of existing neurons. Saeed says IF, specifically the model, activates the Nrf2 gene pathway 13 that improves detoxification and stem cell activation.
This triggers new cell formation, increases mitochondrial function, and promotes autophagy —the body's natural cleansing process that removes damaged proteins, clears damaged cellular parts, and assists with cellular repair and regeneration.
She adds that restricting your eating window has also been shown to help protect against conditions that have an inflammatory component, such as cardiovascular diseases There are numerous ways to structure your eating plan.
Here's a sample schedule to get you started and provide some structure to your fast. As mentioned earlier, is more restrictive and difficult to follow than other types of fasting that have longer eating windows. Here are some tips to make it more doable:.
Like any other lifestyle change, gradual steps can be more sustainable than diving in headfirst. Saeed recommends first starting out with a hour fasting window, then gradually achieving 14 and 16 hours before making your way to 18 hours.
And you can always return to these fasting plans if you find too difficult. Saeed says you're far more likely to achieve your goal if you write it down and get clear on your "why.
Weight loss, improved metabolic flexibility, reduced insulin or leptin resistance, resetting your poor eating habits and lifestyle habits, anti-aging, lowering inflammation? The idea is that if you have a purpose in mind, you'll fast with more intention and thus be more likely to stick to the plan.
You're more likely to successfully adapt to an IF lifestyle if you believe you can do it. Work on changing limiting beliefs and replacing them with positive affirmations. Saeed suggests picking a schedule that supports your lifestyle and sticking to it.
For most folks, that would look something like starting your first meal at p. and ending your eating window at p. She urges folks starting IF to maintain their normal daily schedule and to keep busy.
It's a common misconception that you can still reap the benefits of IF while loading your body with oversize portions of your favorite comfort foods. She recommends avoiding processed foods that contain added sugar, gluten, seed oils , and chemical food additives. Breaking up longer fasts by drinking a cup of broth can also help stave off hunger though it will technically "break" your fast.
Hunger pangs might be the most distracting bodily mechanism in the world. But if you don't give in to them right away, you'll be promoting your body's fat-burning processes, according to Saeed. A break in your eating routine may understandably trigger a stress response.
Saeed encourages you to use stress management techniques like meditation, mindfulness, grounding, belly breathing, nature, exercise, and tech breaks to get through it. Detoxing may be one of IF's most prized benefits, but it can initially present itself in uncomfortable ways, according to Saeed.
You can manage these symptoms by supporting your body's natural detoxification pathways. But if symptoms continue for a few weeks, it's a sign you might want to adjust your fasting schedule.
It's not enough to simply fast—the success of IF requires adequate hydration. If you're looking for more excitement than plain water, Saeed says you can also hydrate with plain green and black teas and other teas like ginger and herbal, which are packed with polyphenols and other compounds that stimulate autophagy.
Keep in mind that when you fast, you run the risk of flushing out electrolytes like sodium, potassium, magnesium, and chloride that impact every cell of your body. And, "During your feeding window, make sure to salt your food.
If this all sounds a little daunting, remember Pelz's advice: "Unlike any other diet, fasting gets easier with time, so hang in there! It's easy to get confused between the two popular IF modalities, but they impact the body differently.
To find out which style is best for you, Saeed says to "See how you feel. Start with fasting most days of the week, and from there you can throw in the occasional challenge day where you try to extend beyond the hour mark to spur a boost in metabolic flexibility.
Keep in mind that you'll likely experience certain days when you don't feel like eating or don't have access to real, nutrient-dense food, according to Saeed, so that's when you might want to seize the opportunity for an extended fast.
While there's no universal recommendation for the amount of time you can do an fast, Saeed says women will want to be extra cautious about fasting length, due to their hormone fluctuations. If you're age 35 or under, Saeed recommends a more flexible fasting schedule, such as every other day or for a few days a week, and to avoid fasting if you plan on becoming pregnant or are pregnant.
Read this guide to intermittent fasting for women for more information. Overall, she says it's crucial to speak to your doctor to determine if you are a suitable candidate for this type of fasting, and if so, for how long you can safely tolerate it.
The most common side effects of this type of fasting include increased hunger, tiredness, and weakness. Because it can feel restrictive, it can also trigger binge eating, especially in those with a history of eating disorders.
You may also experience digestive issues, "as it may be difficult to fit all your nutritional needs in a smaller window," says Saeed. Pelz warns some people might experience detox reactions with flu-like symptoms, constipation, skin rashes, brain fog, or even gain weight.
Saeed says IF can create nutrient deficiencies or trigger hypoglycemia that may impact and disrupt the production of reproductive hormones. She says if you're unable to regulate your blood sugar, it's a sign that IF may not be the right strategy for you. While IF during menopause and perimenopause can be beneficial, she says it's crucial to pay extra attention to getting proper sleep , managing stress , and getting proper nutrition.
Other populations who should stay away from fasting include children and teens under age 18; pregnant women; those who are breastfeeding or trying to conceive; those being treated for serious kidney, cardiovascular, lung, or liver issues; those with disordered eating or eating disorders; and those who are underweight.
Competing female athletes, those who have undergone recent hospitalization, those struggling with alcohol use, and anyone experiencing significant or prolonged stress should also avoid fasting.
The amount of time you're able to tolerate an fasting lifestyle depends on your doctor's recommendations, as well as the state of your hormones. Saeed says as each stage in a woman's life—whether they're cycling, perimenopausal or menopausal—requires a unique approach to fasting and nutrition and should be done under a doctor's supervision.
It's safe to fast for 18 hours a day so long as you're able to regulate your blood sugar, according to Saeed. Primary signs of low blood sugar or hypoglycemia include fast heartbeat, shaking, nervousness, sweating, and dizziness, according to the CDC.
But once your body adjusts, IF should become easier. While men and women usually see results at different speeds, Pelz says she's seen many people lose around five to 10 pounds in the first month. Intermittent fasting for 18 hours a day can be an incredibly helpful tool in regulating hormones, decreasing brain fog, boosting immunity, and reducing inflammation.
However, due to the nature of negative side effects like tiredness and increased hunger, this type of IF may be tough to adhere to in the long term and may not even be right for you.
