Mariah Carey's diet snub

(BANG) -

Mariah Carey could never diet.

The 'Hero' singer - whose weight has fluctuated in the past - admits she is prone to piling on the pounds but says she could never deny herself her favourite foods.

She said: "I'm very muscular. So I mustn't lift weights. I should rather go swimming or do pilates. And of course I should stick to a diet. But I don't want to do that. I'm always on the go. What could I eat and how would I be able to follow a diet?"

Mariah, 40, also says she would never want to be a size zero and thinks there is too much pressure placed on young girls to be unhealthily skinny.

She told German newspaper Bild am Sonntag: "It's society's fault. We grow up with these magazines which are full of size zero models. But people are just people. It's about personal qualities."

"I don't want to be a size zero. And also, I couldn't be one. My bones would look very ugly. I am the happiest when my curvy parts fit into a US size six."
