How can I gain weight during pregnancy without eating too many calories?

Before I was pregnant I weigh 275. It was not from poor intake habits as I singular ate 700 calories daily and walk a mile a day and 30 minutes, not to mention I worked 8 hour days. My doctor found out. When I found out I as pregnant, I started ingestion 2800 calories daily. However I am very soon 24 weeks pregnant and weigh 225. My doctors said I need to gain substance but am still losing. My doctor said that with the hypothyroid medication I would lose shipment (he said that it is slower because I am pregnant) and more weight afterwards. I am a reliable calorie recorder as I have be fat and thought if I reduced my calories and excercised and ate robust then I would lose immensity. Now that I am pregnant I record my calories to gross sure I am getting enough calories to provide nutrition to me and our child but am losing mass. The doctor said our baby girl is thriving, but I eat so much as is and find it tough to take within 2800 calories sometimes.

Any pregnancy surrounded by which the mother has a chronic medical problem IS high-risk, and wants to be treated as such.

Don't take no for an answer here. You figure out full well that in attendance are two lives at stake here. Your doctor ought to understand it as in good health.
