Walking fast would be a bit more helpful than walking slowly, right?

I was watching a health program the other day

I heard a woman saying she couldn't lose weight no matter how much she walked, but when I watched the video, she was really walking leisurely while sipping coffee. Of course, it wasn't instant coffee mix.

Anyway, I thought it would be better to walk at a bit of a pace rather than slowly. That's correct, right?

Slow learning is trending these days, too.

In a way, I wonder if walking fast isn't exactly that.
