Sam smith weight loss good morning america

— -- Sam Smith is the British pop star who took home awards in four big categories at the Grammy Awards last month.

But Smith is also losing big, revealing Tuesday on Instagram he shed 14 pounds in two weeks.

Smith, 22, said his relationship with food has been “completely transformed” and the secret to his weight-loss success is the book “Eat.

Nourish. Glow.” by Amelia Freer, a British nutritionist to the stars.

In an interview with “Good Morning America,” Freer said she doesn’t “advocate diets.”

Instead, she proposes 10 principles by which to live, including tips such as cutting out processed foods and sugar, stocking the refrigerator with fresh produce and lean proteins and creating one healthy habit at a time to avoid failure.

“So for me the key is about it being real, getting back in the kitchen, cooking from scratch, making sure they are not relying on junk processed convenience food,” Freer said.
