Mark Rippetoe: Losing Bodyfat or Gaining Muscle Mass: Which is More Important?

“Muscle mass comprises between 30 and 50 percent of your body’s total weight — the more the better. Composed of more than 650 muscles, it is the primary user of calories in the active human body, and the storage facility for most of the body’s protein. Muscles are the motors which move the skeleton — the system of levers we use to interact with our environment — and are therefore responsible for our physical relationship with our surroundings.

Fat, on the other hand, is where calories are stored, not used. Mostly, fat just lays there, using very few calories itself but hoping you’ll use the calories it stores as fuel for muscle contraction. In great quantities, the few hormones produced in adipose tissue may become metabolically significant, and in great quantities adipose tissue can become the host of significant amounts of inflammation.”

  1. I am going to get my mom to read this article and see what she thinks about it. She is definitely one of the “the thinner, the better” persuasion and I have been trying to gently encourage her at gaining a bit of muscle and mass would be really helpful as she gets older.

    • Cool!
      Hope it will have some influence on her.
      In this text Rippeote points out another brilliant text from dr. Jonathon Sullivan.
      Maybe you can give her that as well to read?
      “Let’s take muscle atrophy (loss of muscle mass) and sarcopenia (loss of muscle cells) as examples. Muscle loss is endemic in older individuals, and it predicts frailty, illness, loss of independence, injury, and all-cause mortality. [14] The impact on health care costs is significant, and the impact on quality of life and human suffering is incalculable.”

      • She read the article yesterday and she was very surprised, I think. She mentioned, “So maybe as we get older we are supposed to gain a little weight.”

        She was a nurse in the eighties so this kind of stuff is the opposite of what she was taught.
