Have you ever had a friend who takes and takes and takes from you? It's exhausting and draining to spend time with her. You love her and care for her but her neediness has become a burden. You feel drained and stressed because she demands so much from you.
That is what fructose does to the liver. It is a needy burden. Glucose is utilized by nearly every cell in the body. Only about 20% of it is broken down in the liver. But not fructose. You see, when you consume fructose it is up to your liver alone to metabolize it. And when you consume excess amounts of fructose, it becomes quite the burden.
