What's up with sprinting?

So I have been trying to research sprinting and it's effectiveness for weight loss but all the results are varied. I'll read one website that tells me that distance running is better for weight loss and one that tells me that sprinting will get you the same results but with half the time. So I want to know from people who have experience.

Does sprinting help for weight loss?

Is it just as effective as long distance?

How many times a week should you do it?

Will it make my legs bulky?

I'm really confused about the actual results of sprinting haha
