Weigh yourself with a see-saw
This method is also known as the fulcrum method, and it is slightly more practical than some other methods for checking your weight without a scale. But there's a lot of room for error regardless. To use this method, you sit at one end of a see-saw while having the other end loaded with known weights like paint cans which typically weigh about 8 pounds.
You wait till the see-saw achieves equilibrium, and then you count the weight on your side, and that's your body weight. Easy, right? No.
Loading the other side with the right weights can be a hassle. And there's no way to monitor minor weight gains or losses, so this method is grossly unreliable.
Weigh yourself in the bathtub
In the water displacement method, you’ll completely submerge yourself naked in a bathtub, while someone else marks the water level on the tub.
You’ll let some time (perhaps a week) pass and then return to repeat the process, comparing the difference between the last water line and the present water line. If you have taken up more volume this time, you have gained weight; if less, you have lost weight. Do you think it's a ridiculous method? You're not alone in thinking that.
The variables are too many, and the margin for error is enormous. But it is one way to calculate your weight without a scale.
Weigh yourself every morning and night
Experts say that the best time to step on the scale is in the morning after you have emptied your bladders and before eating breakfast or doing any workout. At this time, you're most likely to get a lower number, which will be a more accurate indication of what your weight is.
All through the day, our body weights fluctuate due to water retention and other factors so you must be consistent with your weight checking routine. You may hop on the scale in the morning and at night but make sure to do this regularly. This will enable you to accurately track your weight and get a sense of your weight fluctuation.
When losing weight, when should I weigh myself?
If you’re trying to lose weight, the best time to weigh yourself is in the morning before breakfast, workout or drinking any liquids. That's when you'd realize your actual weight. Make sure to use a calibrated weighing scale that is in proper condition. That’s the only way you can trust the number on the scale which, by the way, is likely to be a number that will make you feel good.
It is also best to weigh in one day each week, every week.
And as an aside, it helps to have accountability partners who you regularly call or email with updates about your progress or lapses in your weight-loss journey.
I wish you the best results.
