Recently, I decided to measure my body fat percent on a body composition machine and boy oh boy was I nowhere near happy by the numbers. I’ve been going to my workouts religiously and watching what I eat, for the most part. My pant size has gone down 2 sizes, I’m much more toned and definitely stronger than I’ve ever been before. Why haven’t my numbers changed?? Here are some reasons as to why numbers do not really reflect that change that is DEFINITELY going on within you.
Equipment used to measure body fat percent is not always accurate!
The most common of all equipment to measure body fat percent is the bioelectrical impedance, and despite the fact that this machine is commonly available and easy to use, it is probably the least accurate way to measure body fat percentages. Bioelectrical impedance works by sending electrical impulses through the body and measuring how long they take to return; the quicker the return of the impulses are equates to a leaner body (fat hinders the movement of the impulses). This technique is not always accurate because hydration levels can also affect how fast the electrical impulses move through the body. The more hydrated you are the faster the impulses move; therefore if your body was somewhat dehydrated, you will be getting a false reading in regards to your body fat percent. The calipers are probably the most accurate, BUT you need to have a skilled person taking measurements and the measurements need to be taken in the same place at different times to ensure accuracy. It can be hard to remember the exact skin-fold that was measured previously.
The scale and BMI are the worst measures of weight loss.
Both the scale and body mass index (BMI) do not take your muscle mass into account. Therefore if you are someone that is working out and doing a lot of resistance training – you are building muscle. Muscle weighs more than fat. So, your weight might increase or stay the same regardless of the fact that you are actually losing fat and dropping in size. If you are not exercising and only restricting your food then using a scale to monitor your weight loss could actually be beneficial. Although to be completely honest with you, I do not like the term weight loss and prefer to focus on fat loss. Taking a look at BMI, it is a calculation of your weight and height. It does not take into account how much of your weight actually comes from muscle or fat, therefore it is the worst indication of whether or not you are at a healthy weight range.
The numbers may frustrate you, but don’t let them bring you down! Numbers do not always reflect everything. As long as you feel good about yourself, then that is all that matters. Make sure you are exercising, eating and sleeping well. Remember, any change you make should be a lifestyle one and not a temporary one. I hope this helps you if you’ve been let down by your weight.
