A woman in a short sleeve ping shirt is thinking of different ways to hack hunger while fasting because she's sitting at her beige kitchen table and reaching towards a chocolate candy bar sitting in a glass bowl as she makes a face of desperation since she feels like she's starving.

There’s plenty of ways to hack hunger while fasting and in general, they can be categorized by either decreasing appetite, increase feelings of satisfaction, or distracting yourself.10

However, there’s an easy trick to lower appetite and that’s to drink caffeine in the form of coffee or tea.

Of course, some people prefer to avoid caffeine or may not benefit from the suppressant effects so they may want to explore alternate methods, or a combination of the 15 ways to fight hunger below.  

In any case, you don’t have to be miserable while fasting so try out some of the hacks below to reap the benefits of fasting without the downsides of being hungry. 

How To Make Yourself Feel Full When Fasting 

Perhaps the hardest part of fasting is that empty feeling of foodlessness. This feeling can be uncomfortable, and more often than not, will lead to dieters breaking their fast and eating something to fill themselves up. Feeling hungry can even make dieters more susceptible to cravings, and cause them to undo all their hard work! 

Luckily, there are a number of ways to hack hunger and help dieters adhere to their fast, as well as other trending diets like low in carb keto, paleo diets, and low calorie diets for weight loss.

This makes water fasting, in which a person only drinks water, 24 hour fasting, which includes eating nothing for at least 24 hours, and intermittent fasting, where a person only eats during a small window throughout the day, completely possible and sets fasting dieters up for success. 

If attempting to fast, dieters are encouraged to try out any of the easy hunger hacks below, as well as the varying fasting strategies to maximize their fasting adherence. This will help fasters to deal with hunger without eating, and a number of other unforgettable symptoms that comes with fasting for periods of time. Good luck!

#1 Drink More Water to Hydrate & Feel Full

Water is vital for the body’s overall health. But dieters are often unaware that water is a great tool to help with weight loss, too! In fact, it is well researched that drinking more water can aid in weight loss and fat loss for dieters trying to lose extra pounds.1

Furthermore, drinking more water is a great tool for dieters who are fasting. This leaves dieters to be more hydrated, leading to better health outcomes as the body needs water to function.

As an effect of drinking more water, dieters will also feel more full during their fast. This makes fasters less susceptible to cravings, making them much less likely to break their fast. Adding more water into one’s diet can also give the stomach something to digest. This makes dieters less likely to have cramps, bloat, or feel nauseous due to their lack of food. 

There are even some techniques such as water fasting, where a dieter only consumes water for the entirety of their fast. It’s not recommended to do this for a lengthy period of time as the body needs food for overall health. But engaging in water fasting can be helpful to eliminate toxins and clean out a diet’s bodily system. 

#2 Eat Fiber to Survive a Fast

Fiber is a type of carbohydrate that is very important to the body for health and weight loss, and can really aid dieters who are attempting to fast for longer periods of time. When fasting, dieters are eating much less and as a result, have little to digest. This can lead to slower digestion, and might even cause bloating or constipation in some individuals. 

This is where fiber comes in handy. Because fiber is well known to help aid in digestion, eating fiber while fasting can lead to additional weight loss and can prevent some of the symptoms of fasting listed above.2

Try adding high in fiber foods such as vegetables, fruits, or whole grains when breaking a fast. This will help dieters to get important vitamins and nutrients needed for general health, while also supplying lots of rich fiber without too many calories. 

#3 Replace Simple Carbs for Complex or Wholesome Carbs

Complex, wholesome carbohydrates are much healthier than simple, refined carbohydrates. They are known to provide more energy throughout the day, and have a number of vital nutrients such as minerals, vitamins, and essential amino acids that are often stripped away during the processing of simple, refined carbohydrates. 

Their nutrient dense nature helps dieters to feel full for much longer, and aids in weight loss and decreased rates of obesity.3 This makes for the perfect food to break a fast with, as it will provide more energy for fasters and help dieters to fast for longer periods of time. 

Complex carbohydrates can include whole grains, wheat, rolled oats, barley, and quinoa. In fact, this is the answer as to why is quinoa good for weight loss and considered a superfood. It’s a wholesome carbohydrate that is a staple for dieters and fasters everywhere. 

#4 Consume More Protein to Feel Satisfied

Protein is a necessity when it comes with weight loss and muscle building. Not only does this crucial macronutrient help dieters to burn fat and harden muscles, it takes a longer time for the stomach to digest and as a result, dieters feel fuller and satisfied for much longer than if they were to eat simple refined sugars or foods full of saturated fats. 

Dieters who are fasting may struggle to find a high in protein, low in carbohydrate and low in fat food. So for those who are interested in increasing protein in their diet, it is recommended to utilize protein shakes diet plans to properly get enough protein for weight and fat loss.

As an additional benefit, fasters will not only feel full for longer and more satisfied after meal times; dieters who use protein shakes will have additional muscle building and increased metabolism effects. 

#5 Adjust Meal Timing & Frequency to Manage Satiation & Insulin 

Most dieters do not know that insulin, the hormone that helps to regulate blood sugar, follows a 24 hour internal cycle known as the circadian rhythm.4 More simply put, this 24 hour cycle of insulin regulation leaves people to be hungrier and fuller during certain times of the day. 

Fasting dieters should be aware of their insulin cycles to better adjust their meal timing and frequency. This can require trial and error seeing as everybody is different with varying dietary needs. But as a general rule of thumb, insulin often spikes in the morning and evening times.

Dieters attempting to fast should make their fasting window to incorporate these two time frames in order to help combat their body’s natural spike and resulting hunger. 

Ways to Curb Your Appetite While Fasting

While eating filling foods is important, sometimes that’s just not enough and finding ways to lower your appetite can be beneficial. However, one word of caution is to always stay hydrated while fasting, and especially so if using appetite suppressants. 

#6 Appetite Suppressants for Intermittent Fasting

Many dieters looking for ways to hack hunger while fasting might find themselves struggling with their appetite, especially when engaging in intermittent fasting that calls for only eating during a participle window of time frame. This is where appetite suppressants can come in handy!

#7 Drink Coffee or Tea to Fight Fasting Hunger Pangs

Coffee and tea are high in caffeine, which is a well known appetite suppressant. It has been well researched that drinking coffee with a meal will reduce food consumption, leading to less calories being consumed and greater weight loss effects.5

In fact, caffeine can help improve overall energy and increase metabolic rate, further helping fasting dieters to stay active and lose more weight.

Drinking coffee or tea can help aid in the digestion by giving the stomach something to do. Because the stomach is busy digesting these liquids, coffee and tea can help prevent hunger pangs that are often associated with fasting. 

Coffee specifically is well known for its appetite suppressing effects. In part, this is due to the high caffeine content. Additionally, coffee has a bitter taste that acts as an appetite suppressant in most people. So enjoy a cup of coffee instead of breakfast, and try it black to make sure the drink is fasting friendly and minimal calories. 

#8 Try Sparkling Water to Combat Hunger When Fasting

Sparkling water is like water with a bit of a kick. This drink of choice is carbonated, which helps fasting dieters to feel more full after drinking and even reduce appetite too. This is an especially useful way to hack hunger while fasting if a dieter enjoys drinking soda and is attempting to kick the bad habit. 

Sparkling water can even come in a variety of flavors. This helps fasting dieters to reduce their hunger and cravings, allowing them to feel more full and decreasing their likelihood of breaking their fast due to a desire for a tasty treat. Plus, sparkling water can be delicious, while also providing the body with the hydration that it needs. 

#9 Use Apple Cider Vinegar to Reduce Hunger While Fasting

This can include giving the brain something to do that requires a lot of focus, so that it won’t think about food or the hunger it may be experiencing.

Keeping busy with easy distractions can help too, such as cleaning or reading a book. In fact there are a number of distractible ways to hack hunger while fasting; being creative and keeping occupied are key to successfully using this strategy. 

#11 Chew Gum to Ignore Your Tummy Growling 

Sometimes fasting dieters may be craving the sensation of eating rather than eating itself. This is why chewing gum can be an easy and successful hack to help dieters adhere to their fasting regime. 

Gum can provide a lot of flavor on top of the chewing or mastication sensation that the body often associated with eating food. This can help to trick the body into thinking that it is eating food, and can help ease hunger pains, decrease appetite, and even aid in long term weight loss. 

#12 Take a Walk Around the Neighborhood to Get Your Mind Off of Food

Remember, distraction often works when it comes to tricking the body during a fast! And one way to distract the body is to put it to work. Taking a walk around the neighborhood or in a local park is a great way to be active and remove oneself from the presence of food. 

Furthermore, walking is a great way to burn additional calories and to stay healthy, not to mention the associated fat and weight loss with moderate amounts of step taking per day.7 In fact, many dieters using this strategy often wonder can you lose weight by walking 2 miles a day?

#14 Adjust Your Fasting Window

Fasting can look different for every dieter, depending on their overall weight loss and health goals or religious reasons for fasting. So with this in mind, a dieter’s fast can be tailored to each individual and their fasting window can be adjusted for successful outcomes.
