The Claim

In overweight female college students, high-intensity interval training performed three times per week for 12 weeks results in a mean reduction in body weight of 0.99 kg, body fat percentage of 0.82%, and waist circumference of 1.76 cm that is significantly greater than the reductions achieved with moderate-intensity continuous training.

In plain English

Among overweight female college students, 12 weeks of high-intensity interval training three times per week leads to greater reductions in body weight, body fat percentage, and waist circumference compared to moderate-intensity continuous training.

See the scientific wording

In overweight female college students, high-intensity interval training (HIIT) performed three times per week for 12 weeks leads to a mean reduction in body weight of 0.99 kg, body fat percentage of 0.82%, and waist circumference of 1.76 cm, which is significantly greater than the reductions observed with moderate-intensity continuous training (MICT), suggesting HIIT may be a more effective exercise modality for fat loss in this population.

Why this might work

Short bursts of intense exercise cause the body to release more stress hormones, which keep the metabolism running at a higher rate for hours after the workout. This makes the body burn more fat for energy, especially around the waist, compared to slower, steady exercise.

  1. Study: Comparison of the Effects of HIIT and MICT on Weight Loss in Female College Students: A Meta-Analysis

    This study found that overweight female college students who did short, intense workouts three times a week lost more weight, body fat, and waist size than those who did steady, moderate exercise — exactly what the claim says.
