Beyonce has opened up about her struggle to lose weight following her first pregnancy last year.
The popstar revealed that she gained 57lb while carrying her daughter Blue Ivy, who was born in January 2012.
The 31-year-old star told America's Shape magazine: "I'm not a person that is naturally very thin. I am a person that has to work at keeping my body in shape."
However, Beyonce admitted that she regretted putting herself under pressure to get back in shape so quickly after the birth.
She said: "I didn't have a lot of time to lose the weight because I scheduled a show three months after I gave birth, which I would never do again!"
The singer also revealed some of the baby weight loss methods she used following her pregnancy, saying: "I ate a very low-calorie diet. I stayed away from red meat and ate a lot of fish, replaced pasta and rice with quinoa.
"I always have breakfast, say, scrambled egg whites, a vegetable smoothie, or whole-grain cereal with low-fat milk. For lunch and dinner, I eat a lot of fish and vegetables. And throughout the day, I try to stay hydrated.
"I always treat myself to one meal on Sundays when I can have whatever I want. Usually it’s pizza, which is my favourite indulgence."
