While the free version already allows you to add calories to recipes, with WP Recipe Maker Premium you can add all the standard nutrition facts to your recipes:
Once you’ve added nutrition data you can use the [wprm-nutrition-label] shortcode to show a nutrition label:

Total Carbohydrates 71g
Dietary Fiber 4g
