Eating healthy...or trying to!!

I am 8 wks 4 days today and I have zero desire to eat vegetables and salads like I used to. All the foods I used to avoid pre-pregnancy such as French fries have been so tempting. Starches in general like potatoes and white rice have been the best tasting foods. I am afraid of gaining unhealthy weight, I miss my salads and vegetables but they just don't taste the same. Anyone else have a similar experience? Also have not had any energy to exercise so I wonder if I start moving around more my worries about unhealthy weight gain might subside.
