High-intensity interval training helps people lose weight.

Is it true that high-intensity interval training helps people lose weight?

Partly. Several sources partially support the claim: a Wikipedia overview reports moderate body-composition improvements from HIIT, a small workplace trial combining HIIT with calorie restriction found body-weight improvements, and a qualitative cardiac-rehab study reports perceived weight loss. A 2023 systematic review and meta-analysis, however, found HIIT not superior to continuous aerobic training for reducing body fat, so the evidence is mixed and does not fully settle whether HIIT by itself causes weight loss.
