Hi, TyleRoad.
Those of us who are post-obese, reduced-obese, have different metabolisms than those who were never obese, or who are still obese.
Keeping the blood sugar stable is vital.
I have 15-20g/PRO for breakfast, and about 5g/CHO. Usually a few marinated vegs. Some cream in my tea, and 1-2 Tablespoons of butter with the eggs/meat/fish. I use marinated vegs, as the vinegar at the end of a meal cuts right through that insulin-spurt-caused desire for more food or sweets, for me.
Lunch is the same amounts.
Supper is less protein, usually 12g/PRO. Same amount of FAT. A bit more carbs.
I average 50-60P: with approx. 30C, and the fat varies some. Fat is the only thing to vary, really,--as it causes the least amount of blood sugar change. (Ten percent of fat can be made into blood sugar, through the glycerol.)
About half of protein can be broken down into sugar, through gluconeogenesis.
That is why Dr. Bernstein says to reduce protein, if blood sugar is still too high. (With carbs being constant at 30g/day.)
Dr. Bernstein recommends, as a general rule, 6 grams of carbs for breakfast, and 12 for lunch, then, 12 for supper. I do better with smaller amounts of carbs at a time.
It does take some experimenting. Weighing the food, for constant amounts, really does help keep the blood sugar stable.
Also, anything with volume, stimulate nerve endings in the intestines, signaling hormonal responses, which can raise blood sugar. (Chinese restaurant effect. No such thing as a free food, etc. A head of lettuce can raise blood sugar, etc.)
Abnormal glucose regulation requires attentive measures.
I wish you success.
