The singer shared the secret to his weight-loss success on Instagram, crediting his dietary success to nutritionist Amelia Freer.
"[Amelia Freer] has completely transformed my relationship with food,” Smith wrote on an Instagram photo of himself holding Freer’s book. “Everyone go check out her incredible book, and start to live healthy. It's not even about weight loss it's about feeling happy in yourself. Love you Amelia & thank you for making me feel so happy inside and out."
