I didn't cut sugar out, but I didn't cut anything out. I eat whatever I like now. Which, yesterday, was 3 donuts & 2 mars bars. Completely fell off the wagon with overwhelming stress & depression. Today though, I'm back to normal: cheese & onion omelette for breakfast, then whole wheat pasta with pesto for dinner. No sugar in my tea. Oh, and a mug of hot water with lemon first thing.
I'll say one thing about how I managed to get Intuitive Eating to work: I stopped putting sugar in my tea. Then in my coffee. The constant hunger I was having (I mean, constant as in "I had a meal 30 minutes ago... why do I want to pass out with hunger?!") went away. I can never say I cut it out, because I can't do the cutting out thing. But when I go through 10+ cups of tea/coffee a day, a spoonful of white sugar in each one just played havoc with my hunger signal.
I picked up New Scientist last month as they had an article that looked relevant. I think it was this article that basically said that past a certain point, chronic elevated intake of processed sugar messes with your hunger hormones. You have insulin, and processed sugar contributes to making you insulin resistant. You also have grehlin, the hormone that tells you to eat. When eating too much refined sugar, cells would let energy IN, but would continue to produce grehlin, keeping you hungry. Also, it suppressed the production of leptin, the hormone that tells you to stop eating. (ps: this is from memory so correct me if I've got that wrong! I did read studies on it, either a confirmed or suspected link). I'm no endocrinologist, but this is useful stuff for me to know, as in part, I can now pay attention to why my hunger signal is behaving the way it is on response to what I eat, instead of just assuming I have a "willpower problem" and losing my head over it.
Perhaps the more prolonged your access to refined sugar is, the more "addictive" it becomes? As in, over time you'll go through the stages right up to full blown diabetes and then your body has more trouble regulating its response to sugar? Being a possible reason why some can do "in moderation" and some can't, maybe it's as much a hormonal thing as a mental thing? It does seem like both healthy and unhealthy behaviours have a cumulative effect on the entire body.
Sorry for going on a bit, this is kind of my pet subject right now
