Yes, every recipe has estimates for the calorie and macronutrient totals calculated using MyFitnessPal.   Note that these values are estimates and exact values for your own meals may slightly vary depending on weights of meat and vegetables or different brands of ingredients.  If you need precise values you should always weigh and calculate everything on your own.  If you just need estimates for calories and macronutrient totals, the values on the recipes should be proximate. 

Most of the meal prep recipes included in the MPM Club have versions to make them more weight loss or weight gain friendly.  However, because calorie intakes for weight gain and weight loss will be different for everyone you ultimately need to determine what serving size you need to fit your needs.

 Yes.  The recipes include both imperial and metric measurements as well as an adjuster for how many servings you need.  As a note, I use metric measurements especially for the dessert recipes.  If you want them to turn out as close to how I make them as possible, I recommend buying a food scale.  They are cheap and available on Amazon.
