Oh, ((Harmony)), I wish you could find a different doctor. Advising an 800 calorie diet is completely irresponsible on her part. Even if her advice wasn't actually dangerous to your health, she never seems to encourage you in any way. You never feel better having seen her. That is unacceptable!
I never count calories, but even I know that 800 is way too low. Even at 1200 you would have to be careful to choose highly nutritious foods to have a healthy diet. There would be no room for empty calories.
I wish you the best. You truly deserve it.
And..........today I have officially lost all the baby weight. I weigh what I did when I got pregnant with our first child. Never thought it would happen. I'm six pounds under my original goal weight. It feels great. I encourage everyone to keep trying to add more nutrient dense foods, get some exercise, and really go for it. It's totally worth it!!!
