Why Does Working Out Make Me Hungry?

You’re not alone if you find yourself ravenous after a workout. Here’s what’s really going on and what you can do about it.


Exercising can give you more than just a good sweat – it can also increase your appetite in a way that might seem counterintuitive. But why does working out make you hungry? It’s all about biology, hormones, and energy needs. To understand why exercise leads to an increased appetite, we need to take a look at the biological mechanisms behind hunger and satiety (the state of feeling full).

When we think about hunger and satiety, two hormones come into play: ghrelin and leptin. Ghrelin is often referred to as the “hunger hormone” because it helps regulate appetite by increasing hunger or the desire for food. On the other hand, leptin is known as the “satiety hormone” because it decreases hunger and increases feelings of fullness.

Ghrelin and leptin are both affected by exercise – hence why working out makes you hungry. During exercise, ghrelin levels rise while leptin decreases. As a result, these changes in hormones can lead to increased hunger post-workout even if you’ve been eating regularly beforehand. Likewise, if your body isn’t well-fueled before an intense workout session (lack of carbohydrates), ghrelin will become particularly active in order to satisfy your body’s energy need – this exaggerates post-exercise appetite even more!

What is Physiological Hunger?

Physiological hunger is the type of hunger you experience after exercising or any kind of physical activity. It’s the feeling of being hungry that occurs as a result of your body needing more energy to recover after the workout. This can often lead to cravings for unhealthy foods or even overeating. Now, let’s take a closer look at this phenomenon and how it affects people’s eating habits.

How does exercise affect hunger hormones?

Exercise can certainly make you feel hungrier and cause you to eat more, but underlying physiological factors may help explain why. The body has different hormones that control hunger, including ghrelin and leptin. Ghrelin is known as the hunger hormone because it signals your appetite to increase when it senses a decrease in energy stores. Oftentimes physical activity can cause ghrelin levels to jump, resulting in cravings of all types of food, even if the body does not need them. Leptin, on the other hand, is known as the satiety hormone; it works to shut off hunger signals when energy reserves are replenished. It is thought that exercise may reduce leptin concentrations and also lead people to consume more calories than they burned during their workout. Thus, exercising can result in an imbalance of these two hormones that regulate hunger and may push someone’s caloric intake beyond the amount burned during physical activity.

What happens when we don’t eat after exercise?

It’s important to understand the difference between psychological and physiological hunger. Psychological hunger is the urge to eat based on emotions, cravings, and habits. Physiological hunger is directly related to biochemical changes in your body in response to physical activity.

When you exercise, your body not only needs energy but also amino acids (the building blocks of proteins), vitamins, and minerals — all of which are found in the food we eat. After a workout, physiological hunger signals send messages to your brain causing feelings of hunger — even if you’re not truly hungry. This hunger can be overwhelming if it has been awhile since your last meal or snack and can lead to overeating or cravings for unhealthy foods if it is not managed properly.

If you don’t eat anything right after exercise, you can begin to feel weak or lightheaded as well as having difficulty concentrating due to low blood sugar. It’s important not only to replenish energy stores with a healthy meal or snack but also provide needed nutrients such as vitamins and minerals from nutritious foods after each workout session. Eating the right balance of protein, carbohydrates, fats and other nutrients can help enhance post-workout recovery, promote sustained energy levels throughout the day and support muscle growth over time.

What is Psychological Hunger?

Working out can make many people hungry, even when they haven’t exercised intensely enough to burn a lot of calories. This is because working out can cause psychological hunger, which is the desire to eat more even when your body doesn’t need more fuel. Understanding this phenomenon can help you better manage your diet. Let’s take a closer look at why working out can increase your hunger.

How does exercise affect our psychology?

Regular exercise, for the most part, is seen as essential for leading a healthy lifestyle. But how does it actually affect our psychological health? One of the most striking side effects psychologists have noticed among people who exercise regularly is increased feelings of hunger. This phenomenon has been termed “psychological hunger”.

Psychological hunger occurs when people’s psychological states are altered by physical activity and they start to crave food more than they would otherwise. The underlying cause is believed to involve multiple complex psychological and physiological processes, including hormonal changes and neural pathways that influence mood and appetite.

The research in this area has found that regular physical activity can lead to an increase in ghrelin, which is a hormone involved in controlling appetite. Exercise also affects brain centers such as the hypothalamus, which can increase feelings of pleasure after consuming certain foods and make them more attractive to us. Furthermore, exercise leads to increased levels of serotonin, which is linked with feeling more relaxed and less stressed – making us more likely to turn to comfort foods when we are feeling low. Last but not least, engaging in physical activity can boost motivation levels by providing a sense of accomplishment and increasing self-esteem – leading to desires of reward via food consumption!
So while exercising may make us feel hungrier at times than we would normally be compared with sedentary behavior – this doesn’t mean our diet will suffer if we listen out for our bodies’ signals! With careful considerations for portion sizes according to hunger cues rather than eating until full – psychologically-induced hunger sensations can be managed without undermining health goals (or showering away the calories from our morning run!).

What happens when we don’t eat after exercise?

When we don’t eat after exercise, it can lead to psychological hunger. Psychological hunger is a sensation of extreme hunger that’s caused by a combination of physical and mental factors. It’s something most of us have experienced after exercise, but few understand why.

Physical elements that may lead to psychological hunger include low blood sugar levels due to intense exercise, as well as an increased production of hormones in the body such as ghrelin, which is often referred to as the “hunger hormone.” Mental factors such as deprivation from regular eating patterns or cravings triggered by exposure to certain foods can also trigger psychological hunger.

Not eating immediately after working out can cause us to experience psychological hunger and lasting sensations of intense cravings. If we want to maximize our workouts while minimizing or avoiding any kind of post-workout cravings, we should plan ahead be sure to eat a meal or snack that contains both carbohydrates and protein within 30 minutes after exercise. Eating too soon after working out can cause physiological issues such as nausea or stomach cramps—so it’s best not to fill up right away either way! Timing your meals correctly is key for controlling our physical and mental reactions when it comes to food.

What Should You Do?

Working out can increase your appetite, but that doesn’t mean you should just eat whatever you want after a workout. Exercise triggers several hormones and neurotransmitters that help our bodies respond to the physical demands that we put it through. Understanding these changes can help you decide what to eat to avoid over-eating while still getting the nutrients you need. Let’s take a look at what you should do.

Pre-workout nutrition

If you some kind of pre-workout snack, such as a smoothie or a protein bar, it will provide your body with energy and fuel during exercise. Eating prior to working out helps to optimize calories burned and performance. If you are an early morning exerciser, for example, aim for a light snack within 30-45 minutes before exercising.

Focus on macronutrients like healthy carbohydrates and protein that will provide lasting energy for your workout session. Keep in mind that overly large meals may cause GI distress such as bloating or cramping during exercise. To escape this risk, keep your pre-workout carbohydrate meal smaller than usual and go easy on the fiber or fat content when choosing snacks.

You can also consider adding caffeine to your nutritive plan — research has suggested that coffee consumption before exercise is beneficial in terms of reducing perceived effort during intensive workouts and increasing stamina during endurance exercise. Be sure to listen to your body so you can accurately adjust what works best for you and ensure optimal performance!

Post-workout nutrition

In addition to proper pre-workout fueling, replenishing your body’s glycogen stores with carbohydrates and protein after a workout helps build and repair muscle. It is important to devote the same attention to post-workout nutrition that you do to pre-workout nutrition since this will provide your body with the nutrients it needs for recovery. Eating shortly after a workout can also help manage hunger hormones and regulate blood sugar levels, which may help reduce feelings of hunger or cravings by allowing you to feel fuller longer.

When it comes to post-workout nutrition, there are several things you should consider:
• What type of foods should I eat? Carbohydrates like whole grains and fruit, as well as lean protein sources such as yogurt, eggs, or fish provide important building blocks for muscle growth and repair.
• How much food should I eat? Aim for 20-50 grams of carbohydrates within 30 minutes of your workout in combination with 10-20 grams of protein. This can be in the form of a meal or snack depending on when you exercise and how long it takes for your body to digest food.
• When should I eat? If possible, plan ahead so that you can eat around 30 minutes after finishing exercise — this is when your body has the greatest need for energy replenishment and muscle building materials like proteins and carbs.


In conclusion, while there is no definitive answer as to why exercising may prompt some people to become hungry, the science suggests that it could be related to responding to cues such as a notable decrease in weight, feeling hungrier after a workout than ususal due to reflexive digestive responses or the potential stress reaction of wanting additional fuel for later activities. Ultimately, it is important for individuals to understand what works best for them when it comes to responsible eating habits surrounding exercise for optimal health and energy levels. Always remember that physical activity is essential for overall health and wellbeing and fueling your body sufficiently with necessary nutrients should be a priority.
