Energy balance

Exercise training reduces visceral adipose tissue (VAT) independently of total body weight loss, whereas hypocaloric diets reduce total body weight but show minimal change in VAT when weight loss is absent.

If your goal is to reduce dangerous belly fat (visceral adipose tissue), exercise is superior to diet alone when you aren't losing weight on the scale. Dieting reduces overall weight but may not specifically target visceral fat if you don't lose weight. Exercise reduces visceral fat significantly (6.1%) even if your total body weight stays the same, likely because it preserves muscle while burning fat. Stop using the scale as your only measure of success; use waist circumference or imaging if possible.
