what is leucine

Sugar is kryptonite that make us weak! Nature has provided us with the “anti-kryptonite” to fight the evils of sugar in our diet. The essential branched-chain amino acid called Leucine is just the “anti-kryptonite” that we need to combat the ill-effects of sugar. The Leucine Factor Diet focuses on the leucine content in our diets because:

  1. Leucine is very special in its ability to directly stimulate muscle growth and maintenance; no other amino acid has this distinct ability.
  2. Leucine is one of the amino acids that our bodies can’t convert to sugar (the other is lysine)
  3. Leucine is able to boost insulin production, release, and sensitivity. Insulin is the hormone that clears toxic sugar from the blood.
  4. Leucine is unique in its anabolic effects on muscle and catabolic effects on fat.
  5. Leucine and its metabolite HMB limits maintains muscle when dieting to burn fat.

The Beef With Meat

Why is it that the media and doctors have such a “beef” with red meat? Although I eat more fish than meat, I don’t really have much of a beef with lean grass-fed red meat. The problem with red meat is in the inconsistency in the science.
