My son eats 30-35 grams of carbs per meal with 1 unit of humalog. His A1C is down from 8.7 to 5.9 in 10 weeks. His average meal and bedtime blood sugar is under 100 for the last 4 months. He was diagnosed in January. At the time he had been eating a high carb diet, about 270 grams of carbs a day, and at only 50 pounds. That is in line with the basic USRDA. It was about 65% carbs. I personally had moved myself gradually to fewer carbs. My Dad, uncle, grandpa and great grandpa all had diabetes, presumed type 2. I was a biochemist and exercise nutritionist and chemistry teacher over the last 26 years and my wife is a cardiologist. I personally started feeling good when my carbs came down. A lot of the newer science in exercise nutrition has helped confirm that saturated fat and cholesterol is not a cause of heart disease. Actually most of the new research implicates sugar, particularly the fructose fraction, and high omega 6 plant oils. Cholesterol rises primarily as a RESULT of inflammation caused by a high sugar and high Omega-6 diet (in my researched opinion). Butterfat negatively correlates to heart disease. Whole milk negatively correlates to heart disease. Corn oil has a strong correlation to development of type II diabetes while butter and monounsaturated fats do not (butter is negatively correlated). So in my opinion, I personally have come to the conclusion that dietary fat, except for omega-6s, are perfectly healthy and should make up most of one's daily calories (50-70%). Among animals, very few get less than 50% of their calorie net from fat, and mostly from saturated fat (fiber is turned into saturated fat/butyrate in the intestines of large animals like gorillas and cows). My son eats starch, fruit, veggies and full EXTRA fat dairy with each meal, and also has a mix of chicken, beef and egg but only 1-2 ounces per meal). His plate looks like a normal plate of food. For example he has 4-5 small homemade pancakes, banana and a cup of milk for breakfast. Its 30 grams of carbs and 450 calories. That's about what every meal is in macronutrients. He was underweight, and now he's growing, and happy and he comes to every meal with a blood sugar of 85-100. I think that combining carbs with fat also lets the basal work on it. The first thing to realize is that many fats are good and the body's preferred energy source. The brain of children uses about 100 grams of glucose a day. Anyway, I don't use a "low" carb approach as that generally means less than 100 grams a day, but I use a "glucose needs met by diet" approach in which it is presumed that 100-150 grams of carbs a day provides glucose for the brain and nervous system. The body uses 85% fat most of the time anyway. The percentage drops a little with exercise but even running 6 miles in an hour is only going to burn about 40% carbs and 60% fat. The body lives on beta oxidation from oxidized fatty acids. If you eat over 150 grams a day, it gets turned into fat and then used for energy! Anyway this is my educated "opinion" but I don't have time to prove everything on this site. I don't advocate Bernsteins ketogenic diet. Essential carbs are needed to protect the lining of the intesties and mucous membranes, and when you go under 100 grams a day the body will show greater spikes in blood sugar. A study of men who ate less than 50 grams of carbs a day for a year found that their fasting blood sugar was 115, an their glucose after a glucose tolerance test was over 200 for 2 hours. After 2 weeks of eating 125 grams of carbs a day they had fasting blood sugar under 100 and were under 150 throughout the GTT. Also, Bernstein is wrong in some of his conclusions. He assumes that a normal fasting blood sugar is 83 (which it is on a high carb diet) and that ketogenic diets are safe (which they may be) and that someone on a ketogentic diet with enough calories to meet their developmental needs should also have an 83 fasting blood sugar, which is wrong. Someone without diabetes on a ketogenic diet will develop an increased fasting blood sugar of 100-115 over time and its considered to be healthly. He is also dead wrong about how high most people (and kids) peak after a full meal.
