Can working out cause loss of appetite?

Studies have now shown that aerobic exercise — such as running, cycling, and swimming — actually decreases appetite by changing the levels of hormones that drive our state of hunger.

Why do I lose my appetite when I start working out?

How does exercise affect appetite?

Most research shows, for example, that exercise decreases levels of the appetite-stimulating hormone ghrelin and increases levels of the appetite-suppressing hormone leptin. But other research suggests that exercise’s apparent hunger-suppressing effect doesn’t apply to obese women the same way it does to lean women.

Does your appetite change when you start working out?

Can you train your body to be less hungry?

Bottom Line: Both aerobic and resistance exercise can help increase fullness hormones and lead to reduced hunger and calorie intake.

Why do I eat more when I don’t exercise?

There is evidence that exercise influences all of these components. For example, during times of energy deficit (e.g. the day after a big training day), our appetite hormones are signalling for us to eat more, and this may contribute to increased hunger levels.
