Well... if you accept the argument that being a fat-burner is healthier than being a sugar-burner, I'd tend to think that the inevitable conclusion would be to avoid sugary post-workout foods and stick to meat and fat. That's not exactly universally accepted, though (to say the least!) so if you are going to cave into the cravings, you're right, the sugar shouldn't be refined in the least. Fruit PLUS honey sounds way over the top to me, though, since most fruits have been effectively refined by selective breeding (and poor soils) and raw honey is already super-dense in sugar. If you don't have any fat to lose, though, I suppose you could have a plate of raw liver with a blueberry smoothie. <g> - Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 25, 2005 Report Share Posted September 25, 2005 Most fruits are already plenty sweet for me, I don't know why I said that. So if I understand correctly, you suggest that having a depressed blood-sugar level for a while after a workout is not a problem and is not a reason to dump in some sugar? Is there something I can eat before working out that will prevent this and obviate the need/cravings?

I'd advise retraining your body to be a fat-burner, so that it always has plenty of fuel at hand. I wouldn't eat before your workout either, though. Then your digestive system will be competing with your muscles for energy, and both will suffer. - Quote Link to comment Share on other sites More sharing options...

I've been dealing with it by drinking big glasses of water with lemon juice-- maybe 1/2 lemon per glass. It rehydrates me quickly and seems to stabilize my blood sugar. FDA lists lemons as having 1g sugar per, so I don't think it's a simple sugar spike. Quote Link to comment Share on other sites More sharing options...

True, but they list the total carb content of the juice of a lemon as 4g, so I'm guessing the 1g figure is probably an error. 3g of starch in lemon juice?

Yeah, you're right. This one says 5g carbs, with 1.6g being fiber (lost if you're only using the juice?) and 1.5g sugar. No idea where the other ~2g comes from... this site says there's no starch.

My understanding is that the USDA follows the general convention of considering anything with a CH(2)O ratio to be a carbohydrate, yielding some substances that are smaller than sugar to be considered a carb. Lactic acid would be another one.

If your goal is to build muscle maximally, the conventional belief is that you will build more muscle if you have an insulin spike after your workout. Protein is more effective than carb, but both are effective. Consuming sugars with some protein will help maximize this response, and spare the protein for structural use. I would recommend against fruit, because fructose will not produce a quick spike, since it needs to be converted to glucose in the liver, and about a third is converted into fat instead of glucose. I think maple syrup would probably be the best simple sugar to consume in large amounts because I think that it's mostly glucose-based disacharides (maltose) and, of course, raw honey is good, but still has quite a bit of fructose. I would think maybe maple syrup and raw honey at a 1:1 or 1:2 ratio would be good. If your interest is not to maximize the rate of muscle growth, then I wouldn't bother with the sugars, and I would follow 's idea of becoming a fat-burner as an experiment.

Guest guest Posted September 26, 2005 Report Share Posted September 26, 2005 To add on to what is saying: sugars, specifically glucose, will replenish glycogen in the muscles and spare protein from being burned. Whether being on a ketogenic diet will also spare protein or not I'm not sure, but most bodybuilders will tell you that ketogenic diets are horrible to be on while lifting and will not give as much gains as a " normal " bulking diet. Also, the insulin spike will promote muscle-building as insulin also shuttles protein to cells - it's not just an evil fat-builder. That is why you should also consume protein after a workout. If fat-burning is the goal, then complex carbs (vegetables) and lean protein consumed after a workout is better. We all know that fat is good, yes, but when digestion is delayed while the body is catabolic, muscle will most likely be burned. To reiterate Chris' point about fructose: it's a bad option for glycogen-refilling/post-workout. It fills liver glycogen, gets converted to fat easily and doesn't provide the spike needed. -Nina > > Most fruits are already plenty sweet for me, I don't know why I said > > that.

Guest guest Posted September 27, 2005 Report Share Posted September 27, 2005 Thank you very much, and Nina. Very helpful. Muscle-building is definitley my goal, I'm lean already. So protein alone will induce an insulin spike? Interesting. what do you take post-workout? Maple syrup is 65% sucrose according to one site I just found. Maybe you're thinking of brown rice syrup?

Well I wasn't working out for a while because of fasting and then antifungal therapy, and I really lost a LOT of gains, muscle, but especially strength, and just started back this week. Although I'm on an anti-candida regimen, I've decided to forgo too much carb restriction, and am hoping that just using generous HCl and enzymes, spacing my meals properly, eating things that are easy to digest, and antifungals and probiotics will be sufficient. So I started making a smoothie of six raw egg yolks, a tablespoon of raw honey, one or two of maple syrup, and some blueberries, mostly to make sure I have some vitamin C and flavanoids and whatever that are needed for tissue-building. Probably better to take a C/flavanoid with it, since you'd get a lot more. > Maple syrup is 65% sucrose according to one site I just found. Maybe > you're thinking of brown rice syrup? I don't know why I was thinking it was mostly maltose. What was the other 35%? Maltose? If so It still has a reasonable glucose:fructose ratio. Maybe it would be better to use straight glucose (dextrose) with some other nutrient support. Not sure.

He said muscle-building was his priority, in which case supplementing with refined carbs is probably helpful post-workout. The rationale is to produce an insulin spike after the workout which will counteract the exercise-induced cortisol, prevent muscle breakdown during this period, and raise growth factors.

Guest guest Posted September 27, 2005 Report Share Posted September 27, 2005 So I infer that the body easily cleaves maltose into glucose, whereas fructose is a pain to digest, despite being a monosaccharide. Anywhere I can find more info on this? The " power gel " I sometimes use when bicycling contains brown rice syrup, and it sounds like that's mostly maltose. According to Wikipedia, brown rice syrup is " roughly 50% soluble complex carbohydrates <http://en.wikipedia.org/wiki/Carbohydrates>, 45% maltose <http://en.wikipedia.org/wiki/Maltose>, and 3% glucose <http://en.wikipedia.org/wiki/Glucose>. The glucose is absorbed into the bloodstream immediately, the maltose takes up to one and a half hours to be digested, and the complex carbohydrates take from two to three hours, providing a steady supply of energy.

Anywhere I > can find more info on this? Fructose isn't digested at all. It's a monosacharide, so does not need to be broken down. However, it is basically unusable and needs to be converted in the liver. It's well-established that fructose leads to a much slower blood glucose spike because of this, and that roughly a third of it is converted into triglycerides, which is why it raises triglyceride levels. While maltose needs to be digested, that's something that happens comparatively quickly, unless you have dysbiosis or other malabsorption/digestive issues. I have a couple reviews of fructose metabolism here on paper, but they are restricted access online last I knew. However, unless it's been deleted, I'm pretty sure that back in the day a year or two ago I scanned and uploaded one of them to the files section of this list. I'm guessing that actually violates copyright laws but whatever. Anyway, you could look and see if it's there.

Hi Connie, I've been on the list a few years, and I'd warn against trying to formulate a statement that captures what this list is about! LOL! I think people who have been here for a while know what I mean ;-) Well, I was just answering his question. I said if he wanted to maximize muscle building as his #1 priority, that using simple sugars will probably help him build muscle faster, but that if he was not in a rush to build muscle, it would probably be safer to take the slow path and avoid the sugars. My personal *guess* is that, as long as the sugars are not fructose, and as long as they are basically limited to post-workout, they are probably not terribly harmful IF they are not in addition to a meal, but incorporated into a meal. In other words, say you're following Mastering Leptin or the Warrior Diet-- in the former case whatever you eat post-workout should probably precede your dinner quickly or count as your lunch, and in the case of the latter, you'd have to consume it as the first course of your Warrior Meal. But that's just a guess, and I imagine that ultimately, maximum health would mean cutting out the simple sugars. But I also think the intense exercise and energy expenditure would make the simples not so harmful providing there's no gut or metabolism issues.

Guest guest Posted September 28, 2005 Report Share Posted September 28, 2005 Again, to add on to Chris' statements To clarify, maltose is a disaccharide made of two glucose molecules. A simple enzyme action (maltase) in the small intestine cleaves the maltose molecule. It is then absorbed in the small intestine. Fructose can be utilized in both muscle and liver, though it seems that it preferentially goes to the liver. In the liver, it is acted upon by a number of kinases, becoming Fructose-6-phosphate (F6P) etc. until it yields 2 Glyceraldehyde-3-phosphate (G3P) molecules, which is an intermediate in glycolysis. It then travels the same pathway as glucose in ATP (energy) production. What's interesting is that glucose is also first turned into F6P before becoming G3P and continuing on its merry way. Why the body does this, I have no idea. -Nina > Fructose isn't digested at all. It's a monosacharide, so does not > need to be broken down.

Why the body does this, I have no idea. Hi Nina, I'm just going off the top of my head here, but it sounds like the above mechanism is for burning fructose as energy, isn't it? The information I've read says that 60% or so is converted to glucose and eventually reaches the blood as glucose.

It is then absorbed in the small intestine. Unfortunately, anyone whose villi aren't in tip-top shape is likely to produce insufficient maltase, meaning that although maltose is preferable to fructose and fructose-containing disaccharides on the basis of its lower glycation potential, it's dangerous to anyone with any kind of gut problems, as the villi are among the first elements of the digestive system to be injured. - Quote Link to comment Share on other sites More sharing options...
