What happens if you break intermittent fasting for a day

If you’re new to intermittent fasting, you may have a lot of questions about what to do while fasting1. Does coffee break a fast? What about diet soda, or tea? Can I eat a banana? Or a handful of almonds? What if I’m really, really hungry? Read on to discover what really breaks a fast, and how to curb hunger while intermittent fasting for greater success.

Strictly speaking: any amount of calories, no matter how small, disrupts the fasting process. If you’re following your intermittent fasting plan to the letter, that means no calories, whatsoever, for the entirety of your fasting window. And while some say it is possible to preserve the benefits of intermittent fasting—burning fat for fuel, controlled blood sugar levels, etc.—it is not generally recommended to consume anything other than a few select beverages during the fasting window.

What Can You Drink While Fasting?

While eating is definitely off the table while in your fasting window, many people find success with a variety of beverages that can help preserve the benefits of fasting while simultaneously curbing hunger pangs. Here’s a rundown of a few of the most common:

  • Water. Staying hydrated is the most important component to a successful fast. Choose still or sparkling, but be sure to check the label on flavored water, which may have hidden carbs.
  • Coffee and teaIf you can’t imagine your mornings without a cup of coffee or tea, don’t fret! Black coffee and tea contain so few calories (3 calories and 2 calories, respectively; though tea varieties may vary) that you may find they don’t impact your fast at all. Or, you may find that the benefits outweigh the negligible calories. Just be careful to reach for low carb and calorie creamers and sweeteners, if at all.
  • Broth. While broth will technically break your fast, it contains high levels of necessary sodium and other minerals, which helps your body replenish electrolytes and stay hydrated while also fighting off hunger pangs. Most broths also contain very few calories (1/2 cup bone broth contains ~15 calories.)

What Can You Eat While Fasting?

As previously stated, any amount of calories will, technically, break your fast. Even foods with extremely low calories, like celery, still contain fiber and other nutrients that could potentially trigger your body’s digestive process. It’s also possible that the effect of chewing may get your digestive system working, which will actually make you feel hungrier. Therefore, it is not generally recommended to eat during the fasting window.

However, everyone is different, and you should always find what works and feels best for you. What’s key to any weight loss plan—and essential to learning how to curb hunger during intermittent fasting—is consistency. If a small boost helps you see your fasting window through to the finish, and to start fasting again when scheduled, then go for it! And, as always, if you’re feeling faint or ill, you should listen to your body and eat or drink when needed.

Plus, even if your body is no longer in fasting mode, you can still benefit from some of its processes; fat-burning ketosis, for example, still occurs after feeding, so long as you remain under 50 grams of carbs per day. Keeping your blood sugar levels stable is also possible after fasting; just stick with low carb foods to avoid spiking your blood sugar, and keep your body in fat-burning mode. Ultimately, what’s important about intermittent fasting is finding the right tools that help you stick to your routine, rather than preserving the technicality of the fast.

We fast without thinking about it when we sleep through the night, but imagine if fasting for extended periods during the day could change our lives for the better? In recent years, intermittent fasting has moved from the fringes into the limelight. Some consider the word fast to have negative connotations and instead call it time-restricted eating – whatever you decide to call it, intermittent fasting is making its way into public consciousness and gaining popularity.   So, what are the benefits of intermittent fasting, and is it as healthy as fans claim? Let’s take a look.

What is intermittent fasting?

Intermittent fasting fundamentally comes down to strict periods of fasting – aka going without food and drinks that contain calories – set against periods of food consumption.

Like with any popular health trend, there are both enthusiasts and critics. And although intermittent fasting may sound like a diet, technically it isn't as you don't need to cut out any specific foods. Instead, intermittent fasting is considered an eating protocol – focused on the time window you spend eating rather than the amount or type of food you eat.

There are many ways to tackle intermittent fasting, but the at the root of all of the different approaches is to try and eat all of your food for the day within a specified time frame (we'll get into the specific protocols later) instead of grazing throughout the day and night.

Fasting may sound like a challenging way to approach eating. After all, some of us have been conditioned to believe that eating five or six small meals a day is healthy. Or perhaps you've had it drummed into you that breakfast is the most important meal of the day. To some, skipping breakfast feels like a downright crime!

The reality is that people have been fasting well before it became the 'it' trend, whether for religious purposes, out of obligation or for warding off illness. Nowadays, people fast for reasons ranging from weight loss to mental clarity – but how effective is it really?

Intermittent fasting benefits

Followers of intermittent fasting tout a wide range of reasons why they choose to intermittent fast. It's time to look at some of the top benefits of intermittent fasting, and see if it's up your alley or not.

Aids in weight loss

For some, intermittent fasting is an effective tool for weight loss. Because the time you spend eating is more limited, you may naturally consume less food and therefore fewer calories. At the same time, intermittent fasting can lead to hormonal changes that make weight loss easier, including increasing growth hormone levels in the body and managing insulin.

May reduce the risk of diseases

Intermittent fasting can reduce insulin resistance in the body, making it helpful in preventing type II diabetes. It's also showing promise in terms of lowering so-called "bad" cholesterol, which can cause heart disease. Although more human studies are needed when examining the correlation between fasting and disease, results so far have been exciting.

Simplifies life

Once you get used to intermittent fasting, you may end up enjoying the simplicity of a reduced eating window. It requires less planning and meal prep, and could even save you a pretty penny or two!

May increase energy and focus

Many fans of intermittent fasting claim that their concentration and energy levels improve during a fast. The reason? It could be due to the body's release of norepinephrine, a hormone similar to adrenaline that enhances cognition and may also burn fat.

There are many other intermittent fasting benefits on top of all that, but every person is different and may experience different effects. As such, always consult with a primary care physician or medical professional before embarking on any new diet or lifestyle change.

How to intermittent fast  

If you're interested in all the different ways to intermittent fast, here are some of the most common styles and methods:

16/8

The 16/8 protocol is one of the most common methods of intermittent fasting. Also known as the Leangains method, Swedish fitness coach Martin Berkhan popularized this form of intermittent fasting. This method is popular because it can be adapted to busy schedules.  

Instead of eating and snacking from the time you wake up in the morning until it's bedtime, with the 16/8 protocol you fast for 16 hours and consume all of your food within an eight-hour window. What makes this style of intermittent fasting so common is that it's very flexible – it's up to you to decide when your eight-hour eating window begins and ends.

Let's say, for example, that you're not a big fan of breakfast. In that case, you could skip your morning meal and break your fast at around 1 pm; then make lunch your first meal and eat as you usually would and finish by 9 pm. Begin your fast, then repeat.

If you can't imagine life without your morning oats, change your eating window to one that suits your schedule or natural eating rhythm – you could skip dinner instead and begin your fast at 5 pm and end it (with breakfast) at 9 am.

20/4

This fast follows the same logic as the 16/8; the only difference is that your eating window is only four hours rather than eight. As an example, you could start eating at 5 pm and finish at 9 pm, then fast during the other 20 hours. This is a pretty intense fast, and not for those of you new to fasting, so try not to jump into a fast like this quickly. It's a good idea to work your way up slowly by starting with the 16/8 method and adding on the extra hours of fasting over time.

5/2 Diet

Another one of the most popular intermittent fasting methods is the 5/2 Diet, also known as the Fast Diet. This one differs from 16/8 and 20/4 because the fasting (other than sleep, of course) doesn't need to happen every day. Instead, while following 5/2, you would eat as you usually would for five days, then on the remaining two "fasting" days, you would restrict your diet to just 500 - 600 calories.

It doesn't matter when you have your two low-calorie days, as long as you don't do them back-to-back. Some people find this approach easier because it offers them the possibility to eat regularly for most of the week, while others find it more difficult. It's all about finding something that works for you and your lifestyle.

Is intermittent fasting healthy?

Intermittent fasting is healthy only if you make sure to eat nutritious food during your eating window. If you fast for hours only to binge on junk food during your feeding time, then you won't get the benefits of intermittent fasting that people go on about.

It's also important to note: If you have a history of disordered eating, are underweight, pregnant, breastfeeding or on prescription medications, be sure to consult your doctor or a specialist before trying intermittent fasting, as it could be dangerous for your situation.

Intermittent fasting and working out

You may be asking yourself if it's ok to get in your 8fit workout during the fasting period, and the answer is, yes. In fact, many people prefer to work out while fasting as they feel lighter and more energized. For instance, you could time your workout to just before your fast ends, that way you can enjoy a post-workout meal as soon as you're done exercising.

In the end, deciding on how to get the most out of intermittent fasting and exercise depends on when you time your eating window and workouts. Your best bet is to experiment with different methods until you find the perfect intermittent fasting protocol to fit your lifestyle. If intermittent fasting doesn't seem to work for you or you feel unwell, then listen to your body and return to your usual eating routine.

Can I take a one day break from intermittent fasting?

It's totally okay to take a break if you need to. Give yourself a day to refocus. Stay on a healthy eating track but allow yourself treats like an awesome protein smoothie or a serving of healthy beef and broccoli and jump back in the next day.

What to do if you break your intermittent fasting?

Stick to whole foods and opt for a mix of macronutrients when you break a fast. Avoid carb-loaded meals and sugary drinks and avoid eating a huge meal or you might experience symptoms like bloating.

How often can I break intermittent fasting?

You abstain from food for the remaining 16 hours, though you're still allowed to drink water and other no-calorie beverages, like plain coffee or tea. You can repeat this cycle as frequently as you'd like — from just once or twice per week to every day, depending on your preference.

Do you need to intermittent fast every day?

How Often Should You Use It? In other words - do you need to use Intermittent Fasting every day to reap the benefits? In short, yes and no. By using Intermittent Fasting even a couple of days per week, you're allowing your body to get some amount of gut rest and lower insulin levels in order to achieve your goal.
