There's your problem right there. One of the biggest misconceptions perpetuated by the low-carb "industry" (even Atkins) is that you can eat "low carb" candy with the belief that it is only 1-2 grams of carbohydrates.
The dirty little lie about this stuff is that these foods almost always contain large quantities of sugar alcohols (e.g. malitol, sorbital, lacitol, erythritol, etc.). Depending on the candy, sometimes upwards of 40 grams PER serving. As you (should) know, that is more grams of carbohydrates than you're allowed to have in a single day (two days in induction!). The reason these companies are allowed to get away with this is that sugar alcohols don't have as large an effect on insulin levels *for some people*. The problem is that different people respond to them in different ways. Some lucky souls have little to no insulin response from sugar alcohols. Other people (the middle of the curve) have a reduced insulin response compared to regular sugars, and some people react to them the same as they would pure sugar. There's no hard and fast rule, but there is one very unscientific way to gauge your body's reaction to ingestion of sugar alcohols... the CYP (Crap Your Pants) factor.
As diabetics already know (they've been dealing with sugar alcohols forever), one nasty side effect of sugar alcohols is that they can cause gas and diarrhea (the euphamism on the nutrition label is usually "laxative effect"). The reason this happens is the same as why they tend not to spike insulin levels--the human body can't readily digest them. So as they pass undigested through your gut, the bacteria that live there have a field day.
So, if you are prone to the "laxitive effect" of those low-carb candies (even when just eating a normal serving) then conversely you probably don't get much of an insulin response from ingesting them--they have passed largely undigested into your intestines. On the other hand, if you don't notice any digestive problems even after eating excessive amounts of the stuff, then it means your body is digesting them just fine and thus spiking your insulin levels, ruining your diet.
See, it's a lose-lose situation with sugar alcohols. Either you can eat them knowing they won't spoil your diet (be sure a toilet is nearby and get some toilet paper with aloe) or you can eat them without any intestinal "distress" knowing that even small amounts are being treated by your body just like normal sugar.
Most of us are somewhere in between. Also, not all sugar alcohols are created equal. Malitol is the cheapest, and therefore used most often. However, has a high CYP factor and many people show an insulin response from ingensting it. Lacitol is even worse (beware of the sugar-free Reeses PB Cups). The best one (also the most expensive--go figure) is erythritol. It causes minimal digestive problems and also tends to have the smallest effect on your insulin levels.
One other point to note is that some of the less-noble food manufacturers don't even itemize how many grams of sugar alcohols are in their product--they omit it from the carb count for you, leaving you with the notion that the full size chocolate bar you just inhaled only had 1g of carbohydrates. Common sense should set off warning bells, but a lot of people don't know about how macronutrients work so they just assume they are being told the truth. Always look at the ingredient list. If you see something ending in "-tol" near the beginning, just know that it's got a large amount of carbohydrates in it--despite what the nutrition info might tell you.
Sorry to hijack your thread amnesiac. Hopefully people find this information useful.
