@SkinnySally I am very similar, I tend to find a new thing, go all out on it for a few weeks, buy all the kit, read all the research, then abruptly drop it and never think about it again.
Back in 2020 when the world stopped for Covid I went on a weightloss and fitness binge, lost 5 stone March-October, felt fantastic and managed to maintain for about 6months then slipped back into my old ways.
I need to get a handle on it for good!
I am a spreadsheet freak so I've got my new sheet all set up, I've set myself goals based on weight, size, activity levels so even if the scales aren't playing ball I'll be able to congratulate myself for non-scale victory's .
My watch has already congratulated me on an improvement in my resting heart rate since starting Ozempic 4 weeks ago.
There's also other ideas like putting a £1 coin in a jar for every 1lb you lose so that once you hit target or reduce clothes size you have clothes money set aside to spend.
