I see this as a continuum going from Anabolic <—> Catabolic with people tending to fall on either side of point 0, tending toward one or the other. Me, I’d say I’m a 2 on the right side of point 0.
Metabolism 5- 4 – 3 – 2 – 0 – 1 -2 – 3 – 4 – 5 Catabolic Metabolism
Hallmarks of the Anabolic Metabolism:
• Put on muscle easily
• Has difficulty getting lean
• Will respond well to lower carb intakes (approx 30%)
• Responds well to higher training volumes
Hallmarks of the Catabolic Metabolism:
• Has difficulty adding LBM
• Gets lean easily (but has difficulty retaining LBM)
• Responds well to higher carb intakes (approx 50%)
• Responds best to lower training volumes
Where do drugs factor in?
The above is based on non drug using people. Drugs are the great genetic equalizer: those who add muscle easily but can’t get lean are able to do so, and those who have great difficulty adding LBM, but have no problems staying/getting lean, can do so while retaining LBM. Obviously, genetic traits still play a role (or everyone would look identical and respond identical, etc) but drugs allow for genetic limitations in the above, faster recoup, ability to tolerate higher training volumes, etc.
