I'm not a Primal skeptic, I truly believe in Primal but I don't support the idea of Mark advocating a lower carbohydrate intake and, in my opinion, the misleading and flawed 'carbohydrate curve'.
Ketosis and low carbohydrate dieting is for people with very damaged metabolisms who have been consuming processed foods excessively for prolonged periods of time, i.e. older folk, morbidly obese individuals, those who are extremely metobically resistant etc. and only for a temporary period of time, where one can successfully gradually increase carbohydrate consumption.
There are so many health risks associated with low carb, it affects your hormones, thyroid, develops insulin resistence etc. the VLC folk here can disagree with me and that's fine, but the experiences of some who have restricted carbohydrates for a prologned period of time is enough to prove anybody wrong. Young people especially need to avoid glucose deprivation, it will destroy your organs, destroy hormone balance, rapid aging, fatigue, overall poor mental clarity and uncertainty.
What young man eats green vegetables and limited fruit for glucose? Bake some sweet potato (I prefer white) fries, eat bananas, eat white rice. These are all good sources of starch and provide immediate energy. Eat berries, apples, grapes, oranges etc. you NEED sugar. Just enjoy Primal foods overall. I seriously suggest you increase your carbohydrates immediately before your blood sugar drops too low with all that protein and no sugar or starch. I had moments where I was unalert and disorientated after an omelette or steak so severely I had to lay down and my father nearly called an ambulance. Do you know that your electrolytes are probably out of whack, too? You don't eat dairy so minimum calcium and you have limited vegetables and fruit so limited potassium and magnesium. Just research the defeciency symptoms of each of these minerals.
I better stop before I get attacked lolz. I am not diagnosing you, I'm not a nutritionist, just speaking from experience and research. Please forget the idea of ketosis. Primal isn't a meat-only diet. Vegetables and fruits are more nutritious, starch and sugar works wonders for energy and protein builds strength and also provides energy. Fat is great for satiation.
