For the past year the "Stay with Me" singer has been shedding the pounds and sharing his progress on Instagram.

He revealed that the secret behind his transformation was nutritional therapist Amelia Freer and her cookbook, Eat. Nourish. Glow. Posting on Instagram, Sam explained that Amelia had "completely transformed" his relationship with food. "It's not even about weight loss it's about feeling happy in yourself," he wrote.
