There are several factors that can cause your weight
to go up or down - from the food you eat, the fluids you
drink, the amount you sweat, etc.
In the video below you'll see a real world example of this, where I purposely lose 2.5 pounds
in just 90 minutes... and then re-gain it all back again
within 30 minutes!
I know it sounds crazy, but your bodyweight is going up and down like this all the time, whether you are consciously aware of it or not.
Now this brings up the question:
How can you accurately track your body weight if it's constantly fluctuating?
Well in the video below I'm going to show you how to get your "True Body Weight" that you can use for tracking your progress when trying to lose weight (or gain weight).
