Yep. Me too. I was 112 kg on 1st January and the most depressing thing was when I opened the old spreadsheets to start recording - I was more or less the same every time I started on a diet. I work hard, get close to 100kg, then CBA... I'm back to my cruisisng weight of 110kg before I know it.
This time, I'm trying a "decision zone" in the kitchen.
That's the area in which I make most stupid food decisions. So every time I step in it, I have to pause a second and decide whether to chose a piece of friut or the usual cheese sandwich.
Will it work? Past history suggests not.
