KapriceMemberMy wife just read to me from the CNS book that foods with high amounts of corn syrup and fructose are to be avoided, even on carb night.Doesn't that eliminate just about everything we've been craving?Candy bars. Out.Pop. Out.Most pastries are out, too, aren't they?From the logs and discussions, I didn't get the impression people were avoiding these foods.What's up?

Trevor G FullbrightModeratorCandy bars you can have some, but not tons, no pop though.Fructose doesn't do anything be fill liver glycogen and then get stored as fat. It wont raise insulin either which is why it's best to avoid fructose, and try to limit sugar and HCFS to 120-150 - ish grams. Pastries are mostly starch, so it's not that big of a deal, same with stuff like donuts and cookies.

zewskiMemberYea the problem with fructose is that it doesn't spike insulin which doesn't give you the hormonal effects you're looking for. However, Kiefer has mentioned that it's hard to go “overboard” on fructose with CNS. Basically it doesn't help at all, but it doesn't hurt either.

I'd still avoid soda unless you can easily put an upper limit on yourself.I know before I could get 500g of carbs from pop a lone in just a single meal. (I used to be a giant fat ass.)

zewskiMemberYea soda really has no point in your diet if your even slightly worried about health.

KieferParticipantSo….Fructose is a complex subject and Carb Nite needs a lot more detail about how to properly structure meals on refeeds including fat intake and timing and fructose. First, let me say, there's nothing wrong with CORN SYRUP which is mostly glucose polymers. It's HIGH FRUCTOSE CORN SYRUP that's at issue as well as table sugar and, even more importantly agave nectar.One reason to avoid fructose on Carb Nites is that fructose has this horrible ability to be converted directly to fat in the liver (de novo lipogenesis) when an organism is in an energy surplus. But what tells your body if you're in an energy surplus? Weekly caloric load, T3 levels and most importantly in the case of fructose, liver glycogen levels.That means that on Carb Nite, the short answer is: for non-liquid products, go ahead and eat whatever you want, fructose content be damned (unless it's pure agave nectar or it's sweetened with crystalline fructose). Your liver should be glycogen depleted (as well as your muscles) and the preferred path for fructose metabolism won't be to fat. You'll still get an insulin spike from the glucose component (both table sugar and HFCS are 50% glucose) and the fructose will only speed up glycogenesis in the liver. For beverages, they tend to not stimulate a satiating response (as someone pointed out above) because fructose doesn't trigger a decline in ghrelin levels, so sodas and fruit juices could cause over-eating.While most humans should avoid fructose as much as possible, as DH athletes (which everyone here is--an athlete in the sense of performing better at life) you don't need to worry on Carb Nite. (Carb Back Loading is a whole different story).

Kiefer FTW!Not gonna get a better answer then that.

What about confectioner's syrup? Do you have any idea of its composition? Here in Mexico it is labeled as glucose (glucosa para reposteria=pastry glucose)

KieferParticipantWhat about confectioner's syrup? Do you have any idea of its composition? Here in Mexico it is labeled as glucose (glucosa para reposteria=pastry glucose)
Confectioner's syrup is corn syrup possibly made from other sources besides corn, like potato. It's over 90% glucose, so it's a great carb source when used properly.

Yeah, liquid fructose is shit.
Fructose and Glucose StudyThe study included 32 overweight or obese men and women whose average age was 50.Over a 10-week period, the men and women drank either glucose- or fructose-sweetened beverages, totaling 25% of their daily calorie intake, either in an outpatient setting (eight weeks long) or highly controlled inpatient setting (two weeks long).Both the groups gained weight during the trial, but imaging studies revealed that most of the added fat in the fructose group occurred in the belly, while most of the fat gained by the glucose group was subcutaneous (under the skin).Belly fat, but not subcutaneous fat, has been linked to an increased risk for heart disease and diabetes.The fructose group had higher total cholesterol and LDL "bad" cholesterol, plus greater insulin resistance, which are consistent with metabolic syndrome, while the glucose group did not.The research appears in the latest issue of the Journal of Clinical Investigation.
