I take seroquel (quetiapine) for my bipolar disorder what vitamin can i take to counter act the weight gain and help with weight loss?

Vitamins won't help: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and iceberg lettuce (little/no salad dressing). When shopping for fruits, buy small ones no bigger than a tennis ball, because fruits have sugar. Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar & simple starch calories.

Seroquel (quetiapine) & weight: There is no known vitamin depletion associated with taking seroquel, (quetiapine) but it is associated with weight gain, Insulin resistance, and type 2 diabetes in some people. For best results you'll need to make sure you're exercising daily, and eating healthy whole (non-processed w/trans fats) foods -- emphasizing veggies & high-fiber carbs (brown rice, if any) rather than rapidly absorbed sugars.
