Are scales always accurate?

Updated: Jul 10, 2018




Scales are the most common tool we use to control our weight. However, this does not mean that it is the most accurate method to control the changes that occur in our bodies.


It is very common the number of the scale to stick for weeks in the same number while you feel more comfortable in your clothes or you can get into your old clothes that you have not been in for a long time. How does this happen?


Our weight is determined by 3 different values ​​(body fat, muscle mass and body fluids). The weighing scales we have in our house do not analytically analyze body composition, so it's not clear whether the weight lost is fat mass, fluids or even muscle mass. It is commonplace someone who has started a diet for weight loss in conjunction with exercise and for weeks the weight is the same. A common explanation is that body fat starts to decrease and there is an increase in muscle mass. As you understand the number of the scales does not fully reflect our body image.


In which cases does our weight deviate?

  • In women: 4 days after, during and 4 days after menstruation due to the intense retention that might be present.

  • In the presence of reduced bowel function or constipation.

  • Once you have eaten or drunk something. Try not to eat or drink something 2 hours before weighing.

  • Immediately after exercise or other physical activity.

  • When consuming medicines.

The ideal body measurement is at the same time (preferably in the morning) under the same conditions (wearing about the same clothes) and the same day of the week for more valid results.
