Can certain types of exercise like HIIT or resistance training affect appetite and satiety signals?

Exercise and Appetite

Certainly different types of activity including High Intensity Interval Training (HIIT) and resistance training can indeed influence our feelings of hunger and fullness. The impact of exercise, on our appetite is a process that involves factors like hormones the nervous system and even psychological aspects.


To begin with HIIT typically involves bursts of exercise followed by periods of rest or lower intensity. Studies suggest that HIIT can reduce exercise appetite by lowering the production of ghrelin (a hormone that stimulates hunger) and increasing levels of peptide YY (a hormone that promotes satiety).

Resistance Training

Resistance training, which focuses on building muscle strength using weights or body resistance also has an impact on appetite. Regular resistance training can improve body composition by increasing muscle mass and reducing fat. An increase in muscle mass can lead to a resting metabolic rate over time potentially influencing our hunger and fullness cues.

Effect of Exercise on Appetite

Both forms of exercise can also have an effect on hormones involved in regulating appetite. Additionally the psychological benefits of exercise such, as improved mood and stress reduction may also contribute to how we perceive our levels of hunger and fullness.

However it's important to note that everyones response to exercise is highly individualized. Some individuals may experience an increase, in their appetite after exercising while others may find that it suppresses their appetite. Various factors such as the time of day when exercise is done the intensity and duration of the workout and individual fitness levels can all play a role, in how exercise impacts ones appetite.

High Intensity Interval Training and Resistance Training

To summarize both high intensity interval training (HIIT) and resistance training have the potential to influence feelings of fullness and hunger which could ultimately affect eating habits and body composition. However it's important to note that the way these exercises affect appetite can differ significantly from person to person.

Can certain types of exercise like HIIT or resistance training affect appetite and satiety signals?

Sure lets delve into the connection, between types of workouts like High Intensity Interval Training (HIIT) and resistance training and how they affect our hunger levels and feeling of fullness from a perspective.

When we look at HIIT this particular style of exercise involves alternating between periods of giving it our all and short recovery breaks. This intense training might have an impact on our ability to control our appetite through mechanisms which're different from those involved in traditional endurance exercises. For example the high intensity nature of HIIT could potentially influence how our brain responds to signals of hunger or even affect blood flow to areas in the brain that regulate appetite.

On the hand resistance training includes activities like lifting weights or doing bodyweight exercises. It challenges our muscles by applying a load that's often heavier than what they're used to handling. The energy required for repairing and growing muscles after a workout may indirectly impact how our bodies send signals for hunger and satisfaction. As we build muscle mass it can raise our basal metabolic rate (BMR) which's the amount of energy we burn while at rest. This increase might lead to changes in how our body communicates its need for fuel.

It's worth noting that these forms of exercise not have immediate effects, on hormones related to feeling full but also potentially bring about term regulatory changes.

For example regularly participating in resistance training can help improve insulin sensitivity. This in turn can lead to blood sugar levels and prevent the fluctuations that sometimes cause hunger to spike or drop.

Moreover it's important not to overlook the aspects. The feeling of accomplishment, after a high intensity interval training (HIIT) session or the muscle fatigue experienced from a resistance training routine can temporarily distract us from our hunger cues. Additionally our personal expectations and dietary habits influenced by exercise regimens may consciously or subconsciously alter our eating patterns.

Considering the implications of this topic it's worth noting that while both HIIT and resistance training have the potential to affect appetite and feelings of fullness the overall effects are complex and can be influenced by factors such, as genetics, body composition, diet choices, hydration status and overall lifestyle.
