alt Hacker NewsThis study is completely unsurprising to me having read a lot of fitness studies over the years. Work muscles harder, muscles get stronger. That is how hormesis goes. The fat loss is simple energy expenditure. You are still producing roughly the same work as someone doing more steady state work. Only effect that might come up is post exercise metabolism elevation but that effect is relatively small and probably present for both groups.

But it's not, unless there is a calorie deficit.
If you do aerobic exercise, almost all the energy comes from burning fat. Because your body will have used very little glucose, you're unlikely to feel particularly hungry after that exercise.
If you do anaerobic exercise, almost all the energy comes from glycogen stores. Your body will crave carbohydrates immediately after exercise, and only resort to glucogenesis burning fat if you don't fuel enough afterwards.
There's a significantly higher risk of over-consumption after doing anerobic exercise and aerobic exercise because your body wants to replace the glycogen that got used up.
