Dr. Ted Naiman Discusses Diet



Dr. Ted Naiman, M.D., discusses the impacts of macronutrients (protein, fat, carbohydrate) on blood sugar and insulin levels (i.e. glycemic index and load), insulin resistance vs. insulin sensitivity, naturally selected human metabolic adaptations to prehistoric diet (wild foods), our likely maladaptation (from an evolutionary perspective) to foods relatively recently introduced (on an evolutionary time scale) to the human menu, and how this all may explain why the many diseases of civilization rarely or never occurred among hunter-gatherers.

I enjoyed the video presentation and website info. So I dropped my carbs down to 1/2 cup of berries and 1/2 cup of cultured cottage cheese (stopped eating beans, potato, orange, cherries/grapes).

Also eating a lot of non-starchy vegetables. Not counting the low-carb vegetables, I'm around 10 or 12 grams carbs.


Protein today: 3 eggs, cottage cheese, sardines, 4 oz chicken breast--about 80 grams.

Increased my coconut oil to 2 tbs, and more olive oil.

Feel better, stronger, so far.

Next week, after my blood draw, I may buy some bacon, butter, and ground beef for more saturated fat. Haven't eaten these for three months, I don't especially enjoy my present low animal fat diet. In early November I'll get the lab results and will know if the low animal fat diet improved my LDL-P.

After a few days, I found out the hard way why Dr. Naiman advises eating LOTS of green vegetables on this diet. Potassium! Fortunately, I found some old spinach in the fridge and was able to get back on my feet in a few hours after eating a meal including all the vegetables I had available.

Then I drove to the store and bought vegetables, especially spinach, and a bag of oranges. One orange per day, and spinach with every meal, for more potassium, and now I feel fine.

In the future, I may occasionally eat some sweet potato for variety, but not regular potatoes, grains, or beans. The concept of elevated insulin and its repercussions is just too disturbing, especially for someone who was formerly insulin resistant.

On another video, an interview with Ivor Cummins, Naiman mentions that he (like Cummins) has an elevated LDL-P score, but has patients with a zero coronary calcium score (heart scan) who also have elevated LDL-P scores. He thinks the jury is still out on LDL-P.

Silvertabby,

Some advocates of low carbohydrate eating say that the reason one experiences potassium losses on a low carbohydrate diet is that insulin stimulates water retention, so when insulin drops, you start releasing water and with that goes minerals down the drain.

These doctors recommend ensuring higher sodium intake to reduce water and mineral losses. When I tried low sodium and low carb, I got symptoms of potassium deficiency, mainly cramps in calves. When I increased my sodium (salt) intake, it appears to take care of this.

Also, some doctors say that so-called "keto flu" or low-carb flu – general malaise when eat low carb, is often due to loss of sodium, potassium and other minerals due to the same mechanism. Keeping sodium intake up can prevent or eliminate this malaise.
