Neddy:
I "suffer" from the same "affliction" as well. I generally do well for 2-5 days, then have a complete breakdown and binge on 3000+ calories...it's as if my fullness mechanism isn't working. In fact, it even has a name: Binge Eating Disorder - you can find more information on the internet.
Fortunately, however, I have found triggers that increase the liklihood of these episodes occurring, and I have discovered some strategies to help prevent them on top of avoiding the triggers.
For me, which is not to say that your triggers are the same, being out for dinner is my kryptonite. Because I will normally have a drink when out for dinner, which lowers my inhibition, and the menu is not established for people like us who are cautious about calorie density, sodium intake, calories from fat, etc...I am starting with the cards stacked against me. Toss in some dessert, and I have all the makings to go home and toss back a giant bowl of ice cream with cookie chasers!
I have other triggers as well, such as restricting my calories too much and allowing my blood sugar and hunger to get out of control. Being surrounded with calorie dense foods, particularly in social situation can be difficult as well.
So, some of my strategies to cope with these problems are:
1) Eat when you are hungry! Don't focus too much on weight loss. Eat for your health.
2) Eat to train, do not train to eat. The weight (fat in particular), will come off with patience, not overnight!
3) Find foods that are not calorie dense and enjoy them with abandon. (Well, almost abandon). After all, it's all about calories in versus calories out. As much as you run, your body needs fuel! Restricting calories too much will ONLY backfire by causing drastic blood sugar drops. Read up on the concept of fullness or satiety. Some of my examples are spinach salads (pay particular attention to the dressing - you can find some extremely light dressings which have only 20 calories per serving if you look hard, such as Consortzio Strawberry or Mango vinagrette, apples, popcorn with low calorie and low sodium seasoning, basically lots of fruits and vegetables, Grains and nuts for healthy fats, and lots of fish and lean proteins. Protein is critical for fullness, and I find when mixed with lots of fiber from fruits and vegetables, stays with you longer and keeps you feeling full longer.
4) The other thing that I do almost habitually, is to have a low calorie protein shake as a dessert or a meal replacement. Remember that when you restric calories too much, especially with as much as you run, you can throw your body into starvation mode, and you could inadvertantly start losing muscle mass, and slow down your metabolism. The brand that I use is Dynalean by a company called Dymatize. The powder contains 42 grams of protein, and just 200 calories when mixed with water and ice and blended for an enormous creamy filling shake before bed time. I usually blend in some blueberries too, and the taste starts to grow on you after awhile. My thinking is that I would rather take the extra 200-300 calories with popcorn and a protein shake on a nightly basis, than run the risk of a 3000 calorie binge a couple times a week. It's a fair trade if you consider that just 1 of these binges per week costs you 3000 calories, but, a good strategy such as an apple and a protein shake before bed costs you just 2100 calories per week. That's a 900 calorie savings - IF you dont have ANY dessert for the rest of the week!
5) Resistance training is critical to maintaining lean muscle mass, and stoking your metabolism. Research also indicates that strength training combined with cardio resluts in more fat loss than either strength or cardio alone.
BTW - one year ago, I was 205 Lbs and had high blood pressure and high cholesterol and led a sedentary life. I know weigh 160 Lbs (yes, this still fluctuates, and yes, it is a constant battle), my blood pressure is normal and I am off all medications. I am training for a summer of international distance triathlons, and exercise 7 days a week if possible, either swimming, biking, running and/or resistance training. I love training, and my lifetime secret goal is to train and attempt a full ironman.
I have more fullness strategies, but, even my strategies are not bulletproof. I would be happy to share more of them with you if you are interested, perhaps we could learn from each other!
