The Claim

In women with obesity, adding 60 minutes per day of supervised high-intensity interval exercise to a 1200-kcal/day calorie-restricted diet for two weeks suppresses post-meal acylated ghrelin levels and reduces feelings of hunger compared to calorie restriction alone, despite equal energy availability between groups.

Cause and effect
1 study reviewed
In plain English

In women with obesity, combining two weeks of daily 60-minute high-intensity interval exercise with a 1200-kcal/day diet lowers post-meal acylated ghrelin levels and reduces hunger compared to the same diet without exercise, even when total calorie intake is identical.

See the scientific wording

In women with obesity, adding 60 minutes per day of supervised high-intensity interval exercise to a 1200-kcal/day calorie-restricted diet for two weeks likely suppresses post-meal acylated ghrelin levels and reduces feelings of hunger compared to calorie restriction alone, despite equal energy availability between groups.

Why this might work

Intense exercise bursts activate the body's stress response system, which directly shuts down the stomach cells that produce the hunger hormone. This causes less hunger hormone to circulate after eating, so the brain receives fewer signals to feel hungry, even when the body is in a calorie deficit.

  1. Study: Short-term interval exercise suppresses acylated ghrelin and hunger during caloric restriction in women with obesity.

    In women with obesity, adding short bursts of intense exercise to a low-calorie diet made them feel less hungry and lowered a hunger hormone after meals, even though they ate the same amount of food as those who didn’t exercise.
