So, my body tends to swell and shrink on a daily basis. One day my engagement ring fits, the next day it’s hard to take off. Or my pants will fit differently day by day. I can even see a physical difference over the course of 24 hours. Am I holding water?
Very possibly. When the body is in a hypometabolic state, the tendency toward edema (water retention) is much higher.
As you get healthier, you’ll likely find that this issue subsides. Though based on all sorts of factors, everyone does have some daily fluctuations in weight and water retention.
