Back on the Wagon, any help appreciated

get counting them calories and remember why you started in the first place !

always reflect back on why you started, it will get you further than anything else

This is what worked for me:

weigh/measure/log every morsel of food
eat at a calorie deficit that will be healthy for YOU
find something you like to do and then do it consistently
have patience
stop quitting - do it every day

If you do this every day, you are building healthy habits that will outlast all the motivation and will power you can imagine. Good luck.
