Walking vs HIIT for visceral fat: which should you choose?
Exercise can reduce visceral fat, but “HIIT is always best” is too broad a conclusion. Walking can be a practical way to build regular aerobic activity; higher-intensity training may suit some people. The useful choice depends on total activity, ability, recovery, health and whether the routine is sustainable.

A winner needs a fair comparison
Exercise studies vary in session duration, intensity, total energy expenditure, participants and the method used to measure abdominal fat. Comparing a headline from one walking study with a percentage from a different HIIT trial does not create a head-to-head result. The broader randomized-trial evidence supports exercise as a way to reduce visceral fat, without giving every person the same winning workout.
Where walking fits
Walking is accessible for many people, can be broken into manageable periods and may be easier to repeat than demanding intervals. Pace and duration can be adjusted. It is still activity even when it does not feel like an extreme workout. For someone starting from little movement, establishing a repeatable routine may be more useful than attempting an intensity they cannot maintain.
Where higher intensity fits
Intervals can be an option for people who enjoy them and can train safely. They require suitable progression and recovery. Breathlessness, joint problems, cardiovascular conditions or other limitations may call for adaptation and clinical advice. More demanding is not automatically better if it produces injury or makes the routine unsustainable. Resistance exercise can address strength alongside aerobic fitness.
Judge the plan by more than your waist
Fitness, strength, energy, adherence and appropriate metabolic markers are useful alongside body-size trends. Avoid checking an internal-fat score after every workout. No single session selects abdominal fat for removal. Choose a plan that can evolve over months and that fits nutrition, sleep and any clinical care, rather than treating one exercise style as a cure.

No. The evidence does not make HIIT a universal requirement. Regular activity can take several forms.
Do crunches count as the same thing?
They train abdominal muscles, but they do not selectively remove the internal abdominal fat depot.
