Hi DMHelner,
I believe you can change to 1200 calories by editing the weight in your profile. Other than that you follow a 1200 calorie per day plan.
You try to prevent weight gain while on certain types of medications by still following the usual routine of exercise and reduced caloric consumption and by understanding why a particular medication causes weight gain. With depakote, your hunger centers in the brain may be altered due to neurotransmitter (brain hormones) balances so you need to be more vigilant when you are eating and watch those calories.
Hope this helps.
