<human>: Provide a brief overview of the text.

Hey guys,

First post here, and I have been successfully dieting now for about 5 weeks at around 1200 calories a day.  The specifics are not too important for my question.

Basically, I'd like to know if there are some specific foods that I can eat during weight loss to prevent health problems from developing and prevent nutritional deficiencies.  As an example, I know that gallstones can be a problem during weight loss, and I understand that eating nuts like almonds on a regular basis has been shown to reduce the chance of gallstones forming.  I'm looking for some specific suggestions similar to this one just to try to make sure I don't harm myself unintentionally during weight loss.

Thanks guys!
<bot>: Curious about specific health problems that can come about directly because of low calorie intake/weight loss.  You guys have any examples such as the gallstones one above and possible diet changes to minimize chances of having the issue?***
