According to nutrition and health experts, we should weigh the weight body in the morning, after we empty the stomach and before we breakfast or exercise.

This not only produces lower scales, but we also get accurate figures about how much we weigh actually.

Also, make sure the scales are on a hard and flat surface, without carpeting, then place your feet in a balanced position on it. That way you'll get the exact numbers that get you to know accurately about your weight.
