Rocky1,
I appreciate your rational and objective position. Most people in your situation would be completely biased against LC, not only because low fat worked so well for you, but because LC did not. You still seem very open minded which is commendable.
With that said, some of us have glucose intolerance, and we do not metabolize carbohydrates well. It does not matter if it is a simple sugar or if it is a starch (many sugars branched together), what matters most for us is
how much we are eating. Low fat will not help; if anything it would make the problem worse, because fat tends to slow gastric emptying (reducing glycemic load), and a low fat diet tends to be a higher carbohydrate one.
I do not think the low fat diet could ever work for me.
I tested my glucose tolerance recently. For two days I ate a moderate fat, higher carb diet. I ate "good carbs", no added sugars. I was feeling hypoglycemic the entire time. Does this sound like a bad breakfast? 1 ounce serving of bran flakes, half a cup of milk, and a small banana. Sounds healthy, but within 2-3 hours I was shaking, sweating, and felt as if I might pass out.
On the third day I challenged myself with 50 grams of dextrose. 1 hr after eating my blood sugar went all the way up to 148, and 2.5 hrs later it went all the way down to 41.
Not only has LC allowed me to straighten out my blood sugar and lose weight, but my health has improved in numerous ways.
My heart health and glucose tolerance seems to be ever improving...
even though my weight and diet are not changing much at all. (

Also, my emotional state & energy is a million times better when I'm well fed (by eating enough & reducing carbs). When in a low-energy state (from under eating to lose weight, or carbohydrate) I become almost bi-polar... I alternate between feeling absolutely horribly miserable and occasionally "okay". On rare occasions I can feel hyper/excited but this is almost always followed by the worst depression ever (I've actually come to "dread" this kind of false happiness since I know what will come after it). I need to sleep for hours and am never quite rested. I just feel tired and miserable all the time. On the other hand, when eating well I feel fantastic. My moods tend to alternate between "okay" and "happy"
. I don't get down like I do otherwise. I need very little sleep and can go on just a couple of hours (although it does catch up to me eventually
on average I need 7 hrs to feel well rested)
Also, I had PCOS. When I really mess up my blood sugar (for example, eating out and making poor choices), symptoms start to come back. I almost invariably get a couple of blemishes ... the first symptom. BTW, going on Atkins the acne I've had since 9 or 10 years old went away completely within days. The other PCOS symptoms followed (hair growth, dark patches , etc).
So, if you have the kind of metabolic issues I have, it's likely that you would not feel very good on a high carb low fat diet. While I will admit prior to LC I was eating a bad diet, even when I eat "healthy carbs" like oatmeal (and I mean the unsweetened irish cut ones that you have to boil forever), and whole grain cereals (loaded with fiber, sugar free) and fruit symptoms come back. I believe I am glucose intolerant, my body makes too much insulin to use dietary sugar (carbohydrate), which causes imbalances in my body and various symptoms of sickness. Lots of people are like that, and cannot tolerate the low fat diet.
Now that just explains why some people feel better reducing carbs rather than reducing fats. What I don't understand is why you began to deteriorate in health following a low carb diet. That doesn't make sense to me, I would think all healthy individuals, glucose intolerant or not, should be able to feel fine on a LC diet. I don't think it's possible for healthy people to have poor fat metabolisms, since fat/meat is our "default" foods (agriculture is relatively new to the human race). Perhaps it's possible, though, some people don't metabolize fat well? Could you please describe your typical day when you were LCing?
