de-lurking for an update (because the results look permanent now; didn't want to post tentative results) :
I have had 2 binges in the last 6 months and cut both short after one big meal. In the past the binge would last a week.
I've kept my 60 pound loss off for ~4 years now.
I stopped doing any active Shangri La diet techniques for seems like more than a year because I
1. stopped eating almost all processed food (protein powders being the only exception)
2. cook for myself all the time. since boiling is the zenith of my cooking ability I just toss ingredients together (mostly a chopped/cubed lean meat plus a bunch of spices and some filler like an egg or tomato paste, onions, ginger, garlic ... standard stuff)
With the protein powder I got a bunch of different flavours and mix up different amounts each time.
So I'm having near zero ditto foods, and weird-spicing (not crazy spicing) most of my caloric intake. IMHO this is probably why I've rarely binged and the binges were short lived.
I've gone from a previous low carb, high fat high protein diet to a medium carb, medium protein, currently low fat diet. Adding a small amount of carbs to the old high fat diet used to put weight on me fast.
I finally bit the bullet, went whole hog and
cut out as much fat as possible and replaced it with carbohydrates (potato, whole fruit, white rice - no liquid calories, no juices or colas, no grains). I've been maintaining since then, not changing anything to see if "damaged metabolism" stuff happens to me before I try any other changes.
Typing this up, I realized that in the last year I have
1. not had any bacon (I used to have at least a pound per week)
2. had 2 steaks (used to be 2 per day, several times per week at one time, when I believed "zero carb means infinite calories lost as ketonuria")
3. a dozen eggs per month at most
I tried intermittent fasting (IF) before as a compliance / adherence technique and a week into it I started losing strength. I raised the calories to maintenance but kept losing strength, so that first IF experiment was a bust.
I tried it again starting 9 months ago, this time with the same (maintenance) calories, but (as noted above) much reduced fat, the same protein and a lot more carbohydrates. I didn't lose strength this time (I'm just doing enough lifting to maintain strength right now).
I haven't changed anything for a while, just to establish a "known base" to work from. I hope I've got a good grasp on this whole thing now, having lost weight and maintained it by counting calories on high fat/low carb and on high carb/low fat, used all kinds of techniques to stay in control of hunger and other eating triggers.
I'm now ready to start really crazy-spicing a lot more of my calories. I might even see a 6 pack some day (without manscaping my torso hair to look like a topiary 6 pack)
