Other than ethical reasons, what's the issue here? Not being snarky; just legitimately curious. I would love to see some hard science and longitudinal studies behind the ostensible benefits of a vegan diet, or the drawbacks of a diet high -- but not overly high -- in animal protein. I realize cooked animal protein and preserved/processed animal protein contains carcinogens, and that too much protein (regardless of source) can cause a variety of problems ranging from kidney impairment to gout. But plant-based sources have their costs as well (phytoestrogens, antinutrients, oxalates, etc.). I've never felt better in my life, and my various lab stats have never looked better, than when I went on a Paleo-esque high fat, low carb diet that was quite rich in animal sources, but which also contained a healthful amount of vegetables (and no fruit). I took the diet as far as ketosis, and after breaking through the ramp-up hurdles, I settled into it and got into fantastic shape. Anecdotal, yes. But I've struggled with "skinny-fatness" for much of my life, and this particular combination made a remarkable improvement on my physique without any changes in my exercise routine. Maybe my caloric consumption shifted a bit, but if anything, it probably shifted north. |
