I'm working 12:30 to 9. I get so tired at about 7 but I get to sleep in a lot!
So I found this on the web when I looked up LC and Morning Sickness....O NO THEY DIDN'T!!!

Research on high protein, low carbohydrate diets and pregnancy
Some animal and human research has shown that high protein, low carbohydrate diets may have adverse effects on the fetus, as well as the offspring later in life. In rat studies, maternal dietary carbohydrate is essential for fetal growth and survival of the newborns.8 Even with a diet that is adequate in calories and protein, restriction of dietary glucose lowers tissue glycogen reserves (i.e., the stored form of glucose) and interferes with the normal development of the glucose-regulating system – the system that uses insulin and other hormones to control blood glucose levels and insures that glucose is delivered to all the cells that need it after birth.8
In research presented at a 2004 conference of the European Society of Human Reproduction and Embryology, a moderately high protein diet (25% of calories) adversely affected genetic imprinting in mice embryos, embryo implantation in the womb and subsequent fetal development. This may be due to the high ammonium levels in the reproductive tract that result from eating a high protein diet. Whether these findings in animals apply to humans is unknown, however the researchers advised women trying to conceive to limit their protein intake to less than 20% of total calories.9
In a British study on humans, pregnant mothers who ate a high meat/fish diet in late pregnancy were shown to have increased cortisol levels.10 This is a concern since in animals, high fetal exposure to cortisol may lead to elevated blood pressure in the offspring later in life. The researchers suggested that high maternal cortisol levels may expose the fetus to excess cortisol and program lifelong excess secretion of cortisol in the offspring. Additional research, with more sensitive measures of food intake, is needed.
In gestational diabetes—when a pregnant woman gets diabetes, but didn’t have it before pregnancy—the top priorities are to promote optimal growth and development of the fetus, normalize blood glucose levels and prevent excessive maternal weight gain.11 In a study investigating the relationship between maternal diet composition and newborn birth weight, a higher carbohydrate diet was linked to a lower occurrence of large birth weight babies.11 Having a large birth weight baby can make delivery more difficult. There were no large birth weight infants among women who consumed over 210 grams of carbohydrates a day. It was suggested that to improve insulin sensitivity in women with gestational diabetes, a high carbohydrate diet, that is also low in fat to limit daily calories, is recommended.
In addition, spreading out carbohydrates throughout the day and using carbohydrates with a low glycemic index—such as most vegetables, fruits, legumes, dairy products and whole grains—can help limit the rise in blood sugar after eating a meal.11 Here again, the idea is not to restrict carbohydrates in the diet, but to choose them wisely.

Why do people still believe that people on LC diets only eat lots and lots of meat!!!! |
