About Meal Prep Calories Calculator

Frequently Asked Questions

Should portions be weighed?

Yes. Weighing is far more accurate than dividing by eye, especially for calorie-dense dishes.

Does cooking change the weight?

Yes. Water loss concentrates calories, so density should be calculated from the cooked weight.
