How wrong is this?

I know it's misleading, but...

Okay, I had a prenatal visit yesterday and I really didn't feel like being lectured about losing two pounds. So I spent the entire day stuffing my face with everything imaginable to get myself back up to last weeks weight. I barely made it, too. I feel bad about being sneaky and sort of a liar, but I'm just sick of being lectured. It would be different if I only went once a month, but I have to hear this every single week! 

I never weighed myself before I got pregnant and was perfectly happy that way. Now I find myself having to check every other day to make sure I'm not losing any more. It gets so frustrating!!!! I seriously need someone to tell me exactly what I'm doing wrong. Here's a list of what I typically eat every day, keeping in mind that I can't have any salt or processed foods, and only three ounces of meat a day.

2-3 bananas

1 large bowl grapes

1-2 grapefruits

1 apple

2-3 oranges

1 bowl fresh veggies (carrots, broccoli, tomatoes...)

1 cup unsalted peanuts and raisins

about 3 ounces of meat with a baked potato

That's a whole heck of a lot of food to me! I'm practically eating all day long and it's not cheap either. I want to make sure I have a healthy baby, and I'm really worried that it's not getting everything it needs because I keep losing weight. If anyone has a suggestion, I'm all ears.
