My Personal Experience with an Ultra-Low Carb Diet
After trying both approaches, my experience suggests that Dr. Jaminet’s position is more clinically relevant. The challenge is that most people will not be able to lower their carb level to Dr. Rosedale’s suggestion of below 20 percent. This very low level is a long reach from the average American diet, which is actually around 50 percent carbohydrate—it is simply too hard. Achieving Dr. Jaminet’s far more carb-liberal recommendations will be enough of a challenge for most.
When I eliminated all my grains and starchy vegetables, I actually experienced some negative effects. My energy levels declined considerably, and my cholesterol, which is normally about 150, rose to over 200. It appears I was suffering a glucose deficiency and this can trigger lipoprotein abnormalities. It also seemed to worsen my kidney function. So, while carbohydrate restriction is a miracle move for most people, like most good things in life, you can overdo it.
This information really underscores how important glucose is as a nutrient, and some people can’t manufacture glucose from protein as well as others, so they need SOME starches in their diet or else they will suffer from metabolic stress.
About half of your proteins have glucose attached to them, and if they don’t have glucose, they simply don’t work well, if at all. Your body needs glucose both as a substrate and as a fuel in order for these proteins to work well. If you drop below 200 calories of glucose per day, you might notice some negative consequences in the way you feel and even in some of your blood work, as I did.
My experience now shows me that I need to have some source of non-vegetable carbs. I still seek to avoid nearly all grains, except for rice and potatoes. I typically limit my total carbohydrate calories to about 25 percent of total daily intake, and my protein to about 15 percent, with the additional 60 percent coming from healthful fats like butter, egg yolks, avocados, coconut oil, nuts and animal fat.
However, that is what works for me. You must listen to YOUR body and perform your own experiment. The bottom line is how your body responds, and you’re the ONLY one who can determine that.
So, if you are going to try eating some grain-based foods, which ones are the least likely to cause a problem? How damaging is wheat versus rice? Or potatoes? Before casting a vote on this, it is important to understand how grains contain different amounts and types of natural toxins that can create problems with your health.
