The 27-year-old singer said her new curvy figure is a result of altering her "obsessive" exercise regime and going vegetarian, reported Contactmusic.
"I'm petrified of anything like that. My friends will think that's hilarious. I ran every day for seven months, maybe too obsessively, and when I stopped I became curvier.
"People underestimate how you can shape your body. Since I stopped eating meat and fish, my body is better than ever," she said.
Goulding credits her vegetarian diet for making her feel healthier and more calm.
