Long: (Summary) Sometimes elimination is easier than moderation.
Just chiming in to say that I'm one who has eliminated an entire food group--carbs. I try to eat <20 grams/day, although that's pretty flexible and I mostly go over, but just by a little bit. That means that, in addition to eliminating refined carbs like sugar, and unrefined carbs like whole grains, fruits, and legumes, and dairy, I also watch the carb count of starchy veggies including green beans, onions, tomatoes. An unbelievably large portion of my carbs comes from cauliflower and broccoli--one instance in which I could say, "then I should eat more kale and leafy greens instead," but I like broccoli and find it easy to eat in quantity, so that's my choice. My body wants carbs badly and eating a little produces the opposite of satiety--I want more and more and more. There is no moderation. Zero tolerance is the only way I've found to get off that hamster-wheel and manage my weight and cravings. Even though I enjoy baking breads and sweets and I love pasta--it is EASIER to say goodby to it all than to fight the metabolic result of trying to accommodate a little bit of carbs. Actually, the urge to eat those things retreats entirely when I am good about watching my intake and I don't even feel denial about skipping those foods. (Yea! Priceless piece of mind about that!)
If I consume carbs, I feel hungrier--often right away. I'll find myself hungry before every meal and often stooging around the kitchen peeking in the cupboards looking for something to eat. I'll fight the desire to binge on whatever form of carbs is available--starts with the cookie and ends with flour tortillas and sandwich bread. I'll get lightheaded and nauseous and need food immediately (blood sugar issues). My pulse will race and I'll have trouble sleeping as if I'd consumed caffeine. Worse yet, I'll wake up the next day, SUPER hungry and wanting only carbs. It can take three or four days (if I last that long) of scrupulously watching every morsel of everything I put in my mouth to repair the damage from the binge and settle back into my stride. It is HARD to string together four successful days as the raging hunger and desire to binge will be with me the entire time and, if I slip up, I'll just repeat the cycle from the beginning. Artificial sweeteners produce the same effect, so those are completely off the list, too.
Just putting this out there for all the people for whom moderation does NOT work--and also as a peek into my metabolism for all the people for whom moderation DOES For me, eliminating carbs feels more like freedom than denial.
