For me a couple of things. I lost the final 2 and a half stone last year, taking me from an obese bmi to one of 22.5 so ideal weight, a place I haven’t been since 2008!!
exercise - I’m short so not only did the couple of hundred calories burnt make it easier to stay in a deficit, it was addictive to see progress. I went from only being able to run 30 seconds in February to easily doing 5ks in just over 30 minutes by the end of the year. Even when I had days off tracking for holidays I stuck with exercising running 3 times a week and lifting weights at home twice a week. Being able to see the shape of my body change even when the scale wasn’t moving much was a great motivator!
tracking accurately what I was eating. I use MacroFactor and apart from planned diet breaks I track every day, whether I was over or under target. This helps the app estimate tdee better but the fact that the app is ‘adherence neutral’ meant it didn’t tell me off for going over calories, I was more likely to log them and learn from past behaviour.
finally going vegan, which I didn’t do for health reasons but I have lost the last couple of stone as a bonus!! I naturally eat more fibre and veg now and have to plan my diet a bit more so have less room for processed food. It’s also far easier to refuse tempting snacks at work etc, as most shop bought cakes/biscuits aren’t vegan!
in total I’ve lost over 6 stone from when I started in 2020, and the mantra it needs to be a lifestyle change not a diet has been true for me. I now am more active in general and want to fuel my body with good food, rather than binge on junk like I did in the past. Challenge for 2024 is now maintaining this weight and lifestyle, but I feel so much happier, more confident and just better in general I’m confident I can get it to stick this time.
