Adele would only lose weight if it affected her sex life.
The 24-year-old singer - who recently gave birth to her first child with partner Simon Konecki - is happy being her size and does not think she needs to change unless her health worsens.
She said: "I read a comment on YouTube that I thought would upset me 'Test pilot for pies' - but I've always been a size 14-16 and been fine with it."
"I would only lose weight if it affected my health or sex life, which it doesn't."
Karl Lagerfeld has previously criticised her size, saying that despite having a great voice she is a "little too fat".
However, weight woes are not the only problem in Adele's life - she is also terrified of audiences when she performs, and admits she once escaped from a fire exit to get away from them.
Speaking in new book 'Adele: The Biography', she said: "I'm scared of audiences. One show in Amsterdam, I was so nervous I escaped out of the fire exit. I've thrown up a couple of times. Once in Brussels, I projectile vomited on someone."
