Only Type 1 diabetics can be in a state of ketosis and have high blood sugar which will lead to ketoacidosis.

In normal humans, insulin will down regulate the production of ketones in proportion to the presence of sugar in the blood, preventing ketoacidosis.

I hope that helps 4 months late.

Many of the complaints made about Atkins center around the extremely restrictive “induction” phase, a two-week period during which only 20 grams of carbohydrates are allowed. This is not, however, the basis of the entire diet – it is meant as a “detox” period to purge the body of carbohydrate dependence before gradually reintroducing healthy carbohydrates to the diet. The purpose of this is to determine an individual’s ability to deal with carbohydrates, as the number of grams one can consume while continuing to lose weight varies from individual to individual.

Hey everyone. My girlfriend is a Type 1 diabetic and has often mentioned “going into keto(acido)sis” and “ketones”, referring to an abnormally high blood sugar level. Since ketones are produced in fasting, which implies low blood sugar, I’m seeing a possibility of contradiction in terms. (In other news, I’m trying to get her to go paleo. Health benefits, people!!)

Does anyone have any experiences with Diabetes and info on this? Thanks!

Dear Mark and friends,

I’ve started going paleo Jen 2009, joyfully rediscovered my 6pack after years and felt better than ever
..only to find that training brazilian jiujitsu 3 days/week + 2 sessions of weights + the occasional walk/sprints ate away some kgs of lean mass as well, making me gaunt!
Guess I should have eaten more carbs..

I’d love to know your suggestions for “intense trainees” like me and Zoran! Thanks again,

Tommy

Zoran,

It’s probably impossible to compete as a pro athlete – or even a top age-grouper – on only 150 grams carbs a day…unless your events last less than 45 minutes and you train hard for less than 45 a day. I guess I will have to do a post just for the athletes who want to be “primal” but also want to train incessantly long and hard.

Maya, zbiggy,

I do mean to “carb up slightly” with some healthier choices, like yams, sweet potatoes, berries, fruits etc. Only to 250-300 grams total for that day and only once in a while (not the 1000 grams that some body-builder sites suggest for “mass”). It would mimic a day Grok found a stash of tubers or honey. That little added carb-up simply has your pancreas secreting a bit more insulin for that day, which is OK if you haven’t been secreting much for a few weeks. If you are coming off years of insulin insensitivity, it might make sense to stay “primal” for a few months before experimenting with a slightly higher carb day. OTOH, if you were to never “carb-up” you’d be fine – it’s just that we want to try to mimic the non-linear, feast-or-famine style of Grok in a more controlled fashion.

markus,
I think you are probably right about that, but hardly anyone eats liver anymore, let alone from animals naturally raised on pasture. Now that I have some non-factory farmed source of liver, I’m trying to cultivate an appreciation for it, abut it isn’t happening overnight and especially for beef liver, requires a lot of mustard or other distraction.

I was very interested to learn how sugar and Vit C compete for uptake in the cell and that a high sugar/grain diet is probably what caused scurvy on the long distance European exploration ships, not so much lack of Vit C. Those crew sailors lived on a high glucose diet of hard tack (dried flat bread), molasses, jams, and only bits of dried meat/fish – non-perishables mainly and very little fresh food (I think the captain and officers had better fare). Eventually some provisions included barrels of sauerkraut, which would have displaced some of the high glucose foods as well as provided extra Vit C to compete for uptake. And of course limes were added to the British navy’s rations.

whole fruit and veg are nice and nutritious – and that’s why i eat them – but they are not unnecessary – organic outdoor naturally reared liver, eggs and whole dairy will provide almost all your mineral and vitamin needs in abundance, along with protein and fat. The only issue is vitamin c, and on a low carb diet you only need a fraction of the RDA. so a little fruit goes a long way

Hey, Mark. All this low-carb and fasting got me thinking: Is it possible to be a pro, or a semi-pro athlete and still run on 100-150g of carbs with a couple of fasts per week? I have done a lot of experiments on myself with switching from high carb to low-carb&high-fat but… I never ever managed to have a good workout followed by a normal recovery with fasting. When I say good workout, I mean 1.5 hours of wrestling or weightlifting or gymnastics. Ofcourse, I have to be partially recovered for the workout the next day. If I don’t eat anything 3 hours after my post-workout meal (25g of protein and 70g of carbs from dried berries or pure glucose) I’m a wreck the next day. If I don’t eat my breakfast, the same thing happens. I won’t even start about the days when I have two workouts.

So… How about a little sport-tuned Paleo diet? (Does it then become the Zone diet?)

P. S. Sorry about my English, I’m from Croatia.
