No chance you could stick the body of the garmin in your bra life? I did that with my Fitbit and it worked well til my new strap came.
My slight indulgence last night resulted in big spike, so I'm recording yesterday's 163 as this weeks weight. I had been steadily dropping 164.6, 164.4, 164, 163 so no bloody way am I putting in 165.2! Get to feck as we say. Especially considering my week of steps and absolute angelic eating.
Welcome mrs, we're a mix of methods here. I calorie count, sometimes taking notice of macros. Best advice I could give is to use some sort of food diary, a notebook if MyFitnessPal isn't your thing, being aware of what/how much you're eating is a great help. If you don't know why you're gaining, you can't fix it
