You should really watch the HBO show The Leftovers , if that ' s not already what you ' re referencing . <| sep |> I was specifically told not to cut carbs too much during pregnancy with gd . A lot of doctors will actually test your urine for ketones as ketosis is not healthy for a developing baby . Your body needs carbs to create the energy and building blocks to form a fetus and a healthy fetus brain . If you look at proketopaleo web sites they ' ll say ' nah it ' s fine ', if you ask most doctors they ' ll say it ' s not worth the risk of doing harm to your body or baby .
