Some anti nutrients may be beneficial in small amounts, I get it but at which dose do they start having negative effects?
It’s the same for every food: when we have enough of it we feel it, either by the stuff becoming less and less tasty or by any other feeling such as a slight nausea, for example. This works well enough only with raw, unprocessed, unmixed, unseasoned paleo or nearly paleo stuff.
This is of course a very complex question. It seems most of these benefits that come from anti nutrients and fiber benefit those with medical problems that are most likely caused by the SAD, no?
It’s possible, and we are more or less all in this case. But most wild animals also regularly eat foods containing what is called “anti-nutrients”.
How do these beneficial factors of anti nutrients and fibers fit into a diet like mine? Well, I don't feel the need to eat anything other than meat/fat.
If you’re fully satisfied that way and are never attracted by the smell of other raw foods, then maybe meat and fat are the only foods you need at this time. But such a condition normally doesn’t last more than few months. At least you should check from time to time by smelling all the other foods you stumble upon. In the wild, meat of large mammals is not always very easy to obtain!
Are these alimentary instincts based on foods you crave as well?
It seems the only time I crave something sweet is if I'm unable to get in some good exercise. After exercising the craving completely diminishes. The same thing happens for most people and it has to do with the increased serotonin production/release from exercise. Eating a bowl of cherries or pasta has been known to have a similar affect on serotonin. I'd rather choose exercise.
Our cravings are formed by memory of previous experiences — or worse experiences with the cooked foodstuff and when on standard cooked diet — and since our needs change over time, cravings don’t necessarily reflect our current needs. We shouldn’t rely on them, but rather on our senses of smell and taste.
I don’t know about such effect of exercise, never experienced that and it’s the first time I read something like that. After a lot of exercise I’m generally hungry, not always for meat and also I don’t always have meat at home: in Europe or when traveling around the World, meat suitable for us raw paleo dieters is not easily available. Then I may have sea fish, shellfish or eggs instead. It’s very likely much safer to alternate this way. See this GCB’s post:
