When Adele joined the music scene in 2008, she was much heavier and unashamed. Adele told People, “I’d lose weight if I was an actress and had to play a role where you’re supposed to be 40 pounds lighter, but weight has nothing to do with my career.”

After her son’s birth in 2012, Adele quit smoking and cut out 10 daily cups of sugary tea. Her nutritionist cited a “clean diet, with lots of fruit and vegetables, plus lean protein and complex carbohydrates” for Adele’s slimmer figure. Regardless, Adele told Rolling Stone she’d “rather have lunch with friends than go to a gym.”
