Group A -5 lbs of red meat per day
Group B-Chronic heavy weightlifting
Group C-Chronic AS use
Group D-All of the above
If each group consisted of 50 test subjects, each measuring blood cholesterol, cardiac hypertrophy, sclerotic plaque formation, HTN, increased LDL, hypercholesterolemia etc. Obviously, you'd get the biggest change in group D, but taking Group D (matarazzo type) out of the equation...over a long term trial, you would see the most DRASTIC effects on the heart (not necessarily bad) from group B and group C. That's considering all things being equal. Hell, just being heavy has an impact on the heart! I remember Flex saying when he was over 270, he couldn't walk up a flight of stairs without stopping for a breather, which organ do you think is taking the worst, minute-by-minute pounding?
But that's not to say that there's not much to be said about red meat consumption. Nobody puts out more studies on the adverse effects of a meat based diet than SDA's. Who have done study after study showing the benefits of a plant based diet, in terms of longevity, cholesterol, obesity, HTN etc. etc. etc. etc.
(oh, but group A will definitely have the highest risk of Colon Cancer
)
