00:0075 minutes. One session. That may be all it takes. Researchers at the University of Hong Kong
00:06ran a randomized trial with 315 overweight adults, all carrying excess fat around the waist.
00:14The trial ran for three years, from September 2021 to September 2024. One group did brisk
00:21interval walking once a week. Another split the same 75 minutes across three sessions.
00:26A third group just attended health education classes. After 16 weeks, both exercise groups
00:33had reduced total body fat mass, body fat percentage, and waist circumference. Both also
00:39improved cardiorespiratory fitness compared with the control group. Body fat was measured with
00:44dual-energy X-ray absorptiometry, so this was not a scale-and-mirror study. Professor Parko-Sue
00:50says once-weekly interval training offers similar benefits and represents a practical exercise
00:56strategy. For anyone juggling work, study, and family, that changes what a realistic exercise
01:02plan can look like. Disclosure. This video contains stock footage and content created or enhanced
