For women who have a high pre-pregnant weight, weight loss is recommended but should be planned carefully and discussed with a physician. Improper dieting or rapid weight loss can interfere with the menstrual cycle and reduce fertility. If pregnancy does occur while a woman is following a severely restrictive diet, the early weeks of pregnancy may be effected. Cease a weight loss effort once pregnancy is established. Pregnancy hormones change the mother's metabolism and, as a result, production of ketones occurs more quickly in pregnant women than others when calories are restricted.
Ketones are toxic to the fetus.
For women who begin pregnancy at a high weight, weight gain goals or pregnancy are set lower. If a slower rate of weight gain is advised and cutting back calories is suggested during pregnancy, this should be done moderately and under the supervision of your physician. All Rights Reserved.
