Shedding weight during pregnancy: not a good thing

This is why making the prenatal nutrition guidelines more stringent in dangerous. This woman was on a 'weight loss' eating plan throughout her pregnancy:

Even though her midwife told her she could stay on the plan (she had been losing weight before falling pregnant for a second time after the birth of her first son) because it was just 'healthy eating', I still find it disturbing that she was not on the plan to 'eat healthfully', she was on the plan with the intention of losing weight.
