Weight Loss Forum / Low Carb / February 2005Question About Daily Glycemic Load
I have two questions about the use of Glycemic Load to control carbs: 1) Let's say you eat two foods at a meal, one with a GL of 7 and one with a GL of 4. What is your GL for the meal? Is it the highest value (7), the combined value (11), or something else? Since GL is based on the number of carbs in a serving along with the GI, my guess is that you can add the values to get a meaningful number. So if you want to stay below 10 at any given point in time, you have to combine all foods to get the cumulative GL. An example -- if you make the Atkins lentil soup listed in his book, you have to combine the GLs of the lentils, swiss chard, onions, etc., to get a GL for the meal you are eating. 2)What's a meaningful way to use GL on a daily basis? Can you have a daily GL target, similar to the Atkins ACE, calculated by simply adding all GL values for the day? If so, what are some good guidelines to follow? What would be considered a low daily GL? Thanks. If I recall correctly, GL assumes a portion size of 100 grams. So, you would not only add them together, you might need to increase the number according to your portion size. My feeling is that counting carbs is sufficient. If a day's carbs are very low, then the day's GL is too.

You know, when you fly a small plane, there are weigjht and load ratios you have to consider, not to mention density altitude and a few other factors. You can spend hours with a calculator over all this, or you can just get a feel for it without having to figure out what you can allow on the plane without having to worry about being overloaded. I would suggest just playing around with your food and not worry about limits too much. You will learn what your body can do and what will work for you. Put the calculator down. Go to http://www.glycemicindex.com/ where Jennnie Brand-Miller has info on GL. I think, in the end, you will have to make your own rules.

It's not the easiest to figure out (though everyone can, it just takes time). What would be really nice is if the GL was part of the nutrition labelling on the package, as they are now doing in Australia. I think a glucose monitor is a good idea, at least to test the 'staples' of your diet. I don't think I'd want to poke myself with a needle every time I eat something :-) I want to understand something. Just why can't we use the carb count for the day as that daily glycemic load? (ignoring protein breaking down into sugar).  Signature223/172.9/180 It's more the effect of the 'spikes' on blood sugar which is the issue (and the resulting insulin response)... so... for example, 120g of carbs from whole wheat bread is good whereas 120g of carbs from white bread would be bad. Exact same amount of carbs, but a very different impact on the body. It comes down to the saying 'it's not just the quantity of the carb, but the quality of the carb' and, actually, more-and-more, it's looking like it's mostly the quality that matters. >I want to understand something. > >Just why can't we use the carb count for the day as that daily >glycemic load?

Basically, it would be an average of 4 and 7 (ie. 5.5). Assuming the portion sizes are equal. It's not 100% accurate, but gives a good estimate. >> 2)What's a meaningful way to use GL on a daily basis?

What would be considered a low daily GL? The GL value of a food is something to consider, just like calorie content, when you are choosing a food. You wouldn't really set a 'target'. Best would be to look at what you eat today that has a high GI (expecially the carbs you eat) and try to replace that item with a low GI food. ie. - replace white bread with sourdough, or whole-wheat bread. - replace corn flakes with frosted flakes, or museli - replace white pasta with whole wheat pasta cooked 'al dente' |
