Rules for weighing by JayEll (not to be confused with expert opinion

)
1. Always weigh at the same time of day.
2. Always weigh on the same scale while wearing the same or similar clothes if possible (or no clothes if that's how you started).
3. Expect variation. Two to three pounds variation isn't unusual due to mystery factors (salty foods, exercise, time of month for women). And if you are heavier, you can see even more variation.
4. Don't weigh too often or the variations will drive you insane!
As for me, I always weigh LESS after my workout. I think I must evaporate...
Good luck!
