DrSassy - interesting read with good information, but I don't think much of his diet. Not for a bodybuilder anyway. Perhaps for a healthy person HIS size, or as a strict contest cutter, but I really don't think much of the 'good carb, bad carb' approach when it comes to naturally grown, unprocessed foods.
There IS the argument that mankind was eating meat and veg before it started growing corn, and possibly our digestive systems reflect this and prefer veg. Fibrous veg might be a nutritional substitute for wholegrains on a purely dietary basis - but not for the budding bodybuilder.
I use myself as an example: if I don't have a large helping of oats or pasta before a workout, I'll burn out halfway through or earlier. Oats and pasta for me, interestingly rice doesn't have the same effect - rice being a 'good' carb as he says. This is, of course, a personal thing, but I'd never advocate a low-carb (I consider veggies low-carb) diet to anyone, whether a bodybuilder or an ordinary person. I DO advise a carb cutoff time though, no grains or rice or potatoes after a certain time in the evening (except if it's PWO/PPWO), after which I eat carbs only in dairy and vegetables. Morning cardio the next day should keep bodyfat in check.
What he says about carbs clogging up digestion is however true (carbs are digested partly in the mouth, then in the stomach where they aren't digested as such, just pass slowly to the small intestine): hence why I eat the protein on my plate first, before I touch any carbs. Say I'm eating chicken breasts and rice, I'd eat every last scrap of the bird before the rice. This way the protein gets digested first and optimally - otherwise it'd mix with the rice as he says and not get digested so easily, hence less aminos will be sent to the bloodstream and put towards muscle growth. On this point we agree. Conversely fat also clogs up digestion in this way, hence liquid fats (i.e. oils) being the preferred choice of fat, although it's not often easy to seperate them (i.e. whole eggs, beef).
As for seperating protein and carbs/fat, I do this but I eat pro/carb or pro/fat meals. I would never eat a carb-only or fat-only meal - I will nibble on some celery while I'm cooking maybe, but I wouldn't have a bread-and-butter sandwich or a hunk of bread on its own if I was eating the way I call 'properly'. And I ALWAYS eat the protein first (where possible).
Substituting grains for sweet potatoes and rice might work for you, try it and see. Some people get fat just by LOOKING at a slice of bread, it's all very individual. Personally I couldn't do without oats - I love them, and I'll take a suggested adipose bump (suggested by the article) AND their health benefits any day (oats lower cholesterol - which should be low anyway - and contain a good deal of fibre amongst other things), and as I've said earlier, I find them to be the BEST workout fuel. I would NOT attempt a gruelling workout on just a plate of broccoli.
Remember we're bodybuilders here, our metabolism SHOULD be accelerated through high-protein (eating first), cardio and weight-lifting, so adipose shouldn't be so much of an issue (cardio) - also we need the low GI of oats, pasta etc to fuel our workouts (at least I do).
So, to recap. The article contains scientific truths which I don't argue with, however I will always argue to the death that we shouldn't attempt a low-carb lifestyle. Right carbs, right amount (eat them to get you through the day, not in excess), right time - limit carbs after hours, concentrate them around the workouts if needs be, but to eliminate them would be detrimental to our lifting and lifestyle in general.
And just in case anyone thought I was preferring grains to veg then I didn't mean that all - I eat heaps of veg for their nutritional benefits and to satiate hunger, but not as workout fuel.
(Oh, and if you've ever been on a low-carb diet you'll know it sucks.)
