Does Working Out Make You Hungry?

Do you ever find yourself feeling hungrier after a workout? It turns out that there may be a scientific reason for that.


Are you one of those people who always feel the urge to eat after a workout? You are not alone! It’s estimated that up to 70% of people experience increased hunger after physical activity. This phenomenon is often referred to as “exercise-induced hunger.” While it’s a relatively common occurrence, the answer to the question: “Does working out make you hungry?” is nuanced and depends on several factors.

The first factor to consider is the duration and intensity of your workout—the longer and more intense your workout, the more likely you are to feel hungrier afterwards. Short, low-intensity workouts (such as yoga or walking) don’t stimulate strong post-workout hunger responses, whereas high-intensity interval training can be an appetite stimulant. Furthermore, different types of exercise involve different metabolic pathways and hormones that can play a role in altering your hunger response.

Your diet can also influence your post-workout hunger levels—studies have shown that increased protein consumption before and during workouts can reduce feelings of appetite afterward. Additionally, proper hydration is essential if you want to keep your post-workout cravings at bay; dehydration suppresses your feeling of fullness while increasing levels of ghrelin (the hormone that tells us we’re hungry).

Finally, psychological factors such as stress or anxiety can play a role in leading us towards unhealthier snacks; studies show that external influences such as marketing campaigns or environmental cues (for example, being near a fast food restaurant) have an influence on food choices even when we do not feel hungry. Understanding the various factors at play will allow you to better manage any post-exercise hunger pangs that may arise.

The Science Behind Working Out and Hunger

Working out requires energy expenditure which will typically make you hungry. However, the science behind this phenomenon isn’t that simple. There are many different factors that influence how hungry we feel after exercising, such as the type and intensity of workout, our diet and hydration levels, and our hormones. In this article, we’ll explore the science behind working out and hunger.

How Exercise Affects Appetite

Exercise is essential for optimal health, but it can have both positive and negative effects on appetite. Exercise increases your energy expenditure and can help regulate the hormones that control hunger, making it an important part of any healthy diet plan.

Exercise generally has a positive effect on appetite in the short-term; studies show that people who exercise feel less hungry for up to two hours following a workout. This is due to improvements in appetite-regulating hormones like leptin, ghrelin, insulin, and peptide YY (PYY). Leptin helps suppress feelings of hunger while ghrelin stimulates feelings of hunger. Research shows that when these hormones are in balance, your body will respond better to controlling cravings and weight management. Additionally, exercise boosts levels of PYY, which helps with satiety or feeling full more quickly when you eat.

Exercise also increases blood flow throughout the body which means your digestive system functions more efficiently. This allows for faster nutrient absorption and improved digestion which can increase overall metabolism rate and leads to better fullness after meals. In addition to the hormonal changes associated with exercise, the combination of better digestion due to increased blood flow and improved hormone balance can contribute to proper appetite regulation after exercising consistently over time.

The Role of Hormones in Hunger

When you work out, the body responds in numerous ways — both directly and indirectly — resulting in potential changes to your hunger levels. These changes are largely due to hormones released during and after physical activity which can increase or decrease appetite.

One of the primary hormones involved in regulating hunger is ghrelin, which acts as an appetite stimulant by increasing our desire for food. Various studies suggest that exercise has a negative relationship with ghrelin levels, minimizing the appetite hormone’s effects on an individual’s feelings of hunger. While it is true that there may be some reduction in ghrelin levels through exercise, it is not definitive; individuals may still experience hunger and cravings despite their workouts.

Leptin is another hormone integral to our daily life and its primary role is to sense energy balance and energy stores or fat mass. Moreover, it also helps regulate body weight by suppressing hunger while encouraging satiety after eating. Studies have shown that general endurance training can increase leptin levels over time resulting in a decreased urge to eat more than usual after exercising. Leptin has also been found to play a role in impaired motivation for food intake when used regularly alongside exercise; however, this effect tends to be restricted to people who are practicing higher-intensity activities such as running marathons or doing resistance training programs along with cardio workouts two or three times a week.

Cortisol (or the “stress hormone”) functions as part of our body’s fight-or-flight response system, but when present at elevated levels for too long (such as with chronic stress), cortisol can stimulate hunger as well as cravings for unhealthy foods high in sugar and/or salt content — both of which can contribute to unintentional weight gain over time if not managed properly alongside appropriate diet and exercise plans. Exercise itself does not cause cortisol levels to rise; this occurs only when we push ourselves too hard or too far beyond our current abilities (this condition technically known as overexertion).

The Role of Stress in Hunger

Whether working out makes you hungry or not is complicated and can depend on many factors like level of intensity, duration, and even the type of workout. There are two main hormones associated with hunger: ghrelin and leptin. Ghrelin is the hormone that increases your appetite and is released mainly shortly before meals. Leptin is the hormone that suppresses appetite after a meal and increases when your fat stores go up.

The role of stress in hunger, however, cannot be ignored. When someone works out they experience an elevation of cortisol levels (known as the “stress hormone”). This elevation activates an increase in ghrelin production which can make some people more hungry after working out. This hunger spike has been shown to be mostly related to intense or longer duration workouts as opposed to low-intensity exercise, but it does vary from person to person nonetheless.

Another factor that plays into whether someone gets hungry after working out or not is the fact that strenuous activities cause a build up of lactic acid in your muscles. If you don’t replenish this lactic acid loss with proper nutrition post-exercise, you may experience more intense cravings for food later on when that energy source has been depleted from your system. It’s important to take note of how hard you are pushing yourself when exercising so as to avoid experiencing overwhelming cravings for food later on down the line!

Tips for Managing Hunger After Working Out

Working out can increase your appetite, and it can be difficult to control your hunger after a workout. It is important to know strategies to help you manage your hunger after exercising so you don’t overindulge in unhealthy foods. This section will explore different techniques to help manage hunger after working out.

Pre-Workout Snacks

Before heading off to gym or starting your exercise routine, it is wise to prepare with a snack that will give you fuel for your session and help you manage your hunger after the workout. Eating a pre-workout snack high in healthy carbohydrates and protein will provide energy for your body without weighing you down. Depending on the amount of time before and after the workout, snacks that are around 100-200 calories are ideal. Useful examples include:
-Greek yogurt mixed with oats or granola
-Apple slices topped with nut butter
-Whole wheat toast topped with smashed avocado
-Overnight oats mixed with fruit
-Nutrition bars high in protein
-Banana or other fruit plus a handful of almonds

By taking the time to properly fuel up pre-workout, you can prevent yourself from feeling faint during higher intensity exercises, while setting yourself up for a successful post workout snack. This way, you’ll be able to meet your nutritional needs while effectively managing hunger levels when exercising becomes part of your regular schedule.


Hydration plays a major role in regulating hunger. When you work out, your body expends energy and burns calories to fuel your activity and restore lost fluids. Make sure you drink plenty of fluids before, during and after exercise to help avoid dehydration. Water is the best choice, but low fat milk or 100 percent fruit juices are also suitable options. Carbonated beverages should be avoided as they can lead to dehydration and an upset stomach. Additionally, adding a few electrolytes (sodium, potassium) to your water can help replenish any you lose during exercise and make it easier for your body to absorb the water. Eating whole foods that are high in water content, like fruits or vegetables can also help in feeling satiated and hydrated following your workout.

Eating the Right Foods

When it comes to managing hunger after working out, the types of food you eat can be just as important as how much and when. While limiting portions and timing your meals correctly is important, it’s also essential to choose nutrient-dense foods that will not only satiate hunger but also provide the necessary fuel for muscle growth and repair. To maximize your post-workout nutrition, try opting for high-quality proteins (such as lean meats, fish, eggs and quinoa), nutritionally rich carbohydrates (such as sweet potatoes, brown rice, oats, legumes and fruits) and unsaturated fats (such as nuts and seeds). Eating enough protein is especially important, since protein has a greater satiating effect than either fat or carbohydrates. If you want to ensure that your body is getting all the nutrients it needs after a hard workout session without consuming too many calories, then opting for healthy snacks or meal replacements can be a great way to do so. Consider conveniently packaged snacks that are packed with combinations of whole ingredients such as nuts and dried fruits; low-fat Greek yogurt with fresh berries; boiled eggs; nutritional bars made with natural ingredients such as oats or chia; or even smoothies with healthy ingredients such as avocado, banana or almond milk.


After assessing the evidence, exercise appears to have both short-term and long-term effects on hunger. While exercise may temporarily increase appetite, regular physical activity contributes to balanced energy levels throughout the day and can lead to a decrease in overall food cravings. Ultimately, research has demonstrated that those who engage in regular physical activity tend to consume fewer calories than those who do not.

In conclusion, working out is not likely to directly influence short-term hunger, but rather could help promote healthier eating habits and a balanced diet over time. The exact impact of working out on hunger will depend on a variety of factors such as duration of exercise session and individual responses to exercise. Therefore, it is important for individuals to remain mindful of their own food intake both before and after physical activity in order to maintain optimal health and well-being.
