The Claim

In overweight and obese individuals, 8 weeks of moderate-intensity continuous training performed three times per week resulted in a statistically significant reduction in body weight and body mass index, while high-intensity interval training performed for a shorter duration showed a non-significant weight reduction compared to baseline.

In plain English

In overweight and obese people, 8 weeks of moderate-intensity exercise three times per week lowered body weight and body mass index, while shorter high-intensity interval training did not produce a statistically significant change in weight compared to before the training.

See the scientific wording

In overweight and obese individuals, 8 weeks of moderate-intensity continuous training performed three times per week resulted in a statistically significant reduction in body weight and body mass index, while high-intensity interval training performed for a shorter duration showed a non-significant weight reduction compared to baseline.

Why this might work

When a person exercises at a steady moderate pace for a longer time, their body burns more fat for fuel and uses more total energy than it takes in, which causes fat stores to shrink and weight to drop. Short, intense bursts don't burn enough extra energy over time to make fat stores shrink reliably.

  1. Study: Effect of high-intensity interval training vs. moderate-intensity continuous training on cardiometabolic risk factors in overweight and obese individuals

    In the study, people who exercised at a steady, moderate pace for 35 minutes three times a week lost a noticeable and statistically reliable amount of weight and BMI. People who did shorter, intense workouts lost some weight too, but not enough to be sure it wasn’t just random. So yes, the steady workouts worked better for showing clear weight loss.
