Sam Smith Reveals He's 4 Pounds From His Goal Weight

— -- For more than a month, Sam Smith has been working hard to get in shape.

Now, he's 4 pounds from his goal weight, he wrote on Instagram.

"Beautiful catch up with the incredible [nutritionist Amelia Freer]," he wrote next to a photo of himself in her kitchen. "Feel happier and healthier than ever."

Smith, 22, said last month that he lost 14 pounds in 14 days with Freer's help. The author of the book "Eat. Nourish. Glow" told ABC News that she doesn't "advocate diets."

"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," she said.
