When you eat a meal at a social gathering, be aware of what a healthy plate should contain. Approximately one half of your plate should contain vegetables and/or fruits. These foods are low in fat, high in fiber and allow you to feel fuller for a longer period of time. The other half of your plate should contain a type of meat and alternatives. However, it is easy to choose the wrong selections for this portion of your plate. Choose lean cuts of meat, fish or choose a vegetarian fare, such as vegetarian chili.
