I have a similar problem. To keep myself in check I’ve been journaling my food at FitDay.com (It’s free!), and keeping a chart on my fridge that I mark daily.
My chart has a line item for each day of that week and a column for each of the following:
Took Vitamin X, Took Vitamin Y, Ate healthy breakfast, Ate healthy lunch, ate healthy snacks, didn’t eat after 9pm (I have a hard time with binge eating at night), Cardio (30 mins+), Yoga/Pilates (20+), Walking (15+), Journaled (my food for that day)
When I complete each section, I cross it off and at the end of the week if I have 35+ marks, I put $10 into my clothes shopping fund. If I have 25+ I put $5 into my clothes shopping fund. If I have less than 25, I get nothing for that week. I may only buy clothes with the money I gain from my charts and may not supplement it with any additional money.
I’m also implementing a monthly reward system where just for filling out each chart (regardless of outcome) for 4 consecutive weeks, I treat myself to a pedicure or something else of approximately the same monetary value.
The rewards systems can always be adjusted (i.e. New video game, new DVD, etc)
I also only have three rules that I MUST stick to.
One, journal my food. All of it. If I miss a day, I have a default caloric entry which is way higher than I probably ate and makes me feel like a total pig.
Two, keep up with my charts. Even if I can only mark off one thing per day, I just make it a point to do so.
Three, make concious food choices. No more mindless feedings while watching the ballgame or chatting on IM. If I’m going to eat some graham crackers and a bowl of sugar, I’m going to question why I’m doing it and I’m going to know exactly how much I’m eating.
This system keeps me from feeling like I’m locked into a particular diet and instead tackles the mentality behind overeating.
I’m down 24 lbs in the last 3 months (since the journaling/charting began) and 41 lbs from one year ago (which is when I started really thinking about why I was overeating and began to listen to WW and Dr. Phil a bit regarding portion control and mindful eating).
It’s slow progress, but it’s the kind of progress that you’re not as tempted to sabotage once you reach your goal. Good luck!
