Keto: what’s the science behind the diet?

While other diet fads come and go, the ultra low carbohydrate Keto
diet seems to endure. But as scientists begin to understand how the

interest in personal nutrition. He explains how the diet works,
what it could be doing to our bodies and what could really be
behind the weight loss people experience while on it. Help support
