1. The South Beach Diet, Arthur Agatston, Random House, 2003
p. 10 “So my eating plan’s first principle was to permit good carbohydrates (fruits, vegetables, and whole grains) and curtail the intake of bad carbohydrates (the highly processed ones, for the most part, where all the fiber had been stripped away during manufacturing).”
p. 12 “I went on the diet. I gave up bread, pasta, rice, and potatoes. No beer.”
p. 50 “And the beer, of course, is nobody’s idea of a diet drink. Maltose, the sugar in beer, has a higher glycemic index than white bread. The insulin response to it leads to the fat storage in the abdomen that we call, quite accurately, the beer belly.”
p. 56 “At the other end of the spectrum is beer. As discussed, it has a high glycemic index thanks to its main component, maltose, which is even worse than table sugar.”
p. 67 “The king of all sugars, the one that increases blood sugar faster than any other, is maltose, which exists in beer. Now you understand what’s behind the beer belly: The rapid rise of blood sugar caused by guzzling this beverage stimulates a corresponding rise in insulin production, which encourages storage of fat around the midsection.”
p. 88 (How to Eat in a Restaurant) “Avoid white wine, spirits, or, worst of all, beer.”
2. Suzanne Somers’ Fast and Easy, Suzanne Somers, Crown Publishers, 2002
p. 81 “As for alcohol, everyone knows it makes you fat, especially beer and hard liquor. Now that you understand the connection between insulin and weight gain around the midsection, a “beer belly” makes perfect sense.”
p. 86 “[Glycemic Index Chart] Beer = 110”
p. 123 “Beer has an extremely high sugar content. In fact, on the Glycemic Index, it rates higher than pure glucose.”
3. The New Sugar Busters! Cut Sugar to Trim Fat, H. Leighton Steward, et al., Ballantine Books, 2003
p. 30 [Glycemic Index List, Miscellaneous, “High”]: “Maltose (as in beer) [=] 105”
p. 87 “As a word of caution, mixers for drinks usually contain a lot of sugar, as does beer (which contains maltose), so neither is considered appropriate for a healthy diet.”
4. Your Last Diet! A Sugar Addict’s Weight-Loss Plan, Kathleen DesMaisons, Ph. D., The Ballantine Publishing Group, 2001
p. 73 “In your detox, you will start by eliminating the known or big sugars. Don’t forget that beer and wine are high in sugar. Technically because hard liquor is distilled, it is not a sugar.”
p. 195 “Alcohol is listed here because even though pure alcohol has no carbohydrate in it, many alcoholic beverages, such as wine and beer, also contain a high percentage of sugars because the rest of the liquids that have not converted to alcohol. The sugars compound the beta-endorphin effect of the alcohol. I think of beer and wine as liquid sugar.”
5. Eat Yourself Slim, Michel Montignac, Michel-Ange Publishing, 1999
p. 33 [Double sugars] “Maltose (glucose + glucose): beer and corn”
p. 38 [High GI Carbohydrates] “Maltose (beer) [=] 110”
p. 38 “BAD CARBOHYDRATES These are the carbohydrates whose assimilation causes a significant rise in glucose in the bloodstream (hyperglycemia)… GOOD CARBOHDYRATES Unlike bad carbohydrates, these are slowly absorbed by the body, resulting in less of a rise in blood sugar (glycemia).”
p. 55 [The American Dietary Model] “Americans are known for their high beer (110) consumption and eat a lot of pre-cooked, processed foods, which all contain corn syrup (100), maltodextrins (100) and modified starches (95). The high glycemic content, then, of the American diet can potentially lead to obesity, diabetes and cardiovascular diseases.”

7. The G. I. Diet - The Easy, Healthy Way to Permanent Weight Loss, Rick Gallop, Workman Publishing, 2002
p. 100 “But remember, because of its high malt content, beer is a high-G. I. beverage, so moderation is particularly important.”

Ch. 4, p. 8 “In choosing carbohydrate foods, both glycemic index and food composition must be considered.” “It is not necessary or desirable to exclude or avoid high GI foods.”
Ch. 4, p. 1 “The glycemic index is defined as the incremental area under the blood glucose response curve of a 50 g carbohydrate portion of a test food expressed as a percent of the same amount of carbohydrate from a standard food taken by the same subject.”

“For an individual food, it is intuitively obvious that the glycemic load will be more relevant than the glycemic index.”
15. The glycemic index at 20 y, David S Ludwig and Robert H Eckel, American Journal of Clinical Nutrition, 2002; 76 (suppl), 264S-5S
“Because there is essentially no rate limitation in the digestion of polysaccharide into glucose, starchy foods (ie, so-called complex carbohydrates) do not necessarily have a lower GI than do simple sugars.”
“However, there is by no means a consensus regarding the utility of the GI to human health and nutrition. Many clinicians and researchers, especially in the United States, have questioned the relevance and practicality of the GI.”
16. Dietary glycemic load assessed by food-frequency questionnaire in relation to plasma high-density-lipoprotein cholesterol and fasting plasma triacylglycerols in postmenopausal women, Liu et al., American Journal of Clinical Nutrition, 2001; 73: 560-6
“Because both the amount and the quality of carbohydrates in a food are important determinants of fasting plasma triacylglycerol concentrations and the postprandial plasma glucose response, we proposed the glycemic load as a measure that incorporates both the quantity and the quality of the dietary carbohydrates consumed… The concept of glycemic load addresses the concern about rating foods as good or bad solely on the basis of their glycemic index.”
17. Dietary Fiber, Glycemic Load, and Risk of NIDDM in Men, Salmerón et al., Diabetes Care, Volume 20, Number 4, April 1997, 545-550
“The glycemic index, as a relative measure of glycemic response to a given amount of carbohydrate, does describe the quality of carbohydrate but does not take into account the quantity. In contrast the total glycemic load represents the combination of quality as well as the quantity of carbohydrate.”
18. Glycemic index and disease, F Xavier Pi-Sunyer, American Journal of Clinical Nutrition, 2002; 76 (suppl): 290S-8S
“Subsequently, the standard against which foods are compared was changed to white bread. This is unfortunate for 2 reasons: first, published GI values conflict; second, 50 g carbohydrate in white bread is more difficult to determine accurately than is 50 g glucose. A comparative standard should be simple, accurate, and reproducible, and the one used to calculate GI is not.”
“In the tables compiled by Foster-Powell and Miller, the variability in the GI of glucose, the carbohydrate that can most accurately be measured, was 85-111 (i.e., 25%)”
19. Dietary Fiber, Glycemic Load, and Risk of NIDDM in Women, Salmerón et al., Journal of the American Medical Association, February 12, 1997, Vol. 277, No. 6, 472-477
“The glycemic index, as a relative measure of glycemic response to a given amount of carbohydrate, does describe the quality of carbohydrate but does not take into account the quantity. In contrast the total glycemic load represents the combination of quality as well as the quantity of carbohydrate consumed and may be interpreted as a measure of dietary insulin demand.”
20. Glycemic index and heart disease, Anthony R. Leeds, American Journal of Clinical Nutrition, 2002; 76 (suppl): 286S-9S
“Proof of the clinical value of low-GI diets awaits prospective trials, which should include short-term observations covering periods of metabolic stress induced by surgery as well as long-term trials with clinical endpoints.”
21. The Gycemic Index, Physiological Mechanisms Relating to Obesity, Diabetes, and Cardiovascular Disease, David S. Ludwig, Journal of the American Medical Association, 2002; 287:2414-2423
“The glycemic index was proposed in 1981 as an alternative system for classifying carbohydrate-containing food. Since then, several hundred scientific articles and numerous popular diet books have been published on the topic. However, the clinical significance of the glycemic index remains the subject of debate.”
“Other questions remain unresolved… Mechanistically oriented studies, multicenter clinical trials, and prospective epidemiological analyses are needed to address these issues.”
22. Glycemic index: overview of implications in health and disease, David JA Jenkins, et al., American Journal of Clinical Nutrition 2002; 76 (suppl): 266S-73S
“The glycemic load, which assesses the total glycemic effect of the diet and has proved very useful in epidemiological studies, is the product of the dietary glycemic index and total dietary carbohydrate.”
“It is said that the glycemic index lacks clinical utility because differences in glycemic index between foods are lost once these foods are consumed in a mixed meal… Appropriate calculation of the mixed-meal glycemic index is therefore required.”
“Over time, the introduction of new foods will expand the range of food choices, providing foods to be selected not only for their glycemic index, but also for their range of health advantages. A certain amount of dietary understanding is certainly required, e.g., carrots with a high glycemic index are not taboo. It is realized that there are other considerations relevant to the consumption of carrots, and that the glycemic index is not significant.”

[Beer] “has so little carbohydrate that the GI value cannot be tested. The GI, therefore, is 0” (p. 38)
24. Sydney University Glycemic Index Research Service (University of Sydney) website <http://www.calvin.biochem.usyd.edu.au/GIDB/mainV4a.htm>
“Foods containing little or no carbohydrate (such as meat, fish, eggs, avocado, wine, beer, spirits, most vegetables) cannot have a GI value. No carbs = no GI.”

Beer is not among this most comprehensive list of published glycemic indices.
26. Sydney University Glycemic Index Research Service (University of Sydney) website <http://www.glycemicindex.com/gi-testing.htm>
“The GI value of a food is determined by feeding 10 or more healthy people a portion of the food containing 50 grams of digestible (available) carbohydrate and then measuring the effect on their blood glucose levels over the next two hours.”
27. Dietary Glycemic Index and Obesity, David S. Ludwig, Journal of Nutrition. 130: 280S-283S, 2000
“The concept of glycemic index (GI) was proposed by Jenkins and colleagues in 1981 to characterize the rate of carbohydrate absorption after a meal (Jenkins, et.al. 1981). GI is defined as the area under the glucose response curve after consumption of 50 G carbohydrate from a test food divided by the area under the curve after consumption of 50 g carbohydrate from a control food, either white bread or glucose.”
28. Effect of alcohol on postmeal fat storage, BJ Sonko et al., American Journal of Clinical Nutrition, Volume 59, pp. 619-625, 1994
“We conclude that alcohol has a fat-sparing effect similar to that of carbohydrate and will only cause fat gain when consumed in excess of normal energy needs.”

“[Response to energy imbalance] revealed that members of the same twin pair are significantly more alike than individuals who are not genetically related by descent. The intra-pair resemblance in response was particularly strong for the changes in body mass, body composition, subcutaneous fat distribution and abdominal visceral fat.”
