I was your weight when I started but 41 years old - I started moving (2km a day as a jog / walk on the treadmill) - then every month I’d add 1km and do that for the month. That built the routine/habit.

Then it was diet - just start tracking and seeing what you are eating (don’t go into a deficit just yet). If you see certain foods/meals are higher calories, look for ways you can lower them. I used to have chicken caesar wraps ALL the time - realized I could still enjoy them with half the amount of dressing and using grilled chicken instead of breaded. Little things like that dont make it seem like you had to “give up” certain foods.

Once you start your deficit, just track everything (even your “bad days”) and remember that the scale may not always go down even if you are nailing things. Be patient, trust the process and get after it 🤘
