 Sucrose Compared With Artificial Sweeteners: Different Effects on Ad Libitum Food Intake and Body Weight After 10 Weeks of Supplementation in Overweight Subjects (Journal Abstract) |
Added on: 9/27/2002 | Hits: 17 |
| From The Royal Veterinary and Agricultural University in Denmark and the American Journal of Clinical Nutrition, 2002: A research team studied the effects of eating sugar versus artificial sweeteners on the voluntary food intake and body weight of overweight people for 10 weeks. They found that the people who ate the sugar ate more food, had higher body wieghts, higher body fat percentages, and higher blood pressures than the people who ate the artificial sweeteners. |

| Postprandial Thermogenesis Is Increased 100% on a High-Protein, Low-Fat Diet Versus a High-Carbohydrate, Low-Fat Diet in Healthy, Young Women (Journal Abstract) |
Added on: 9/19/2002 | Hits: 31 |
| From the Arizona State University and the Journal of The American College of Nutrition, 2002: This team of researchers compared the thermogenic effects of two different low fat diets. The first low fat diet was high in protein and the second was high in carbohydrate. The researchers found that the study participants' body temperature and resting energy expenditure was much higher after eating high protein meals that after eating high carbohydrate meals. They concluded that the thermogenesis that occurs after high-protein meals may partially explain the effectiveness of high-protein diets for weight loss. |

| Body Composition and Hormonal Responses to a Carbohydrate-Restricted Diet (Journal Abstract) |
Added on: 9/13/2002 | Hits: 82 |
| From the University of Connecticut and the journal Metabolism, 2002: These researchers studied two groups of men. One group was placed on a low carbohydrate diet (8% carbohydrate) while the second group remained on an ad lib diet for six weeks. At the end of the study, the low carbohydrate group lost body fat (7.5 pounds on average) while their lean body mass increased by 2.5 pounds. There was also a 34% decrease in insulin levels in the low carbohydrate group. |

| Dietary Composition and Physiologic Adaptations to Energy Restriction (Journal Abstract) |
Added on: 7/31/2002 | Hits: 60 |
| From Harvard and the American Journal of Clinical Nutrition, 2000: This study was conducted and published by Harvard researchers working at Children's Hospital and Brigham & Women's Hospital in Boston. This research team looked at the common concept that one of the reasons that traditional, low calorie diets have low success rates is because there is a physiological “set point” in which our bodies will not allow our weight to fall below. They set out to examine whether the diet’s components affect our bodies ability to adapt to reduced food intake. They compared the effects of a high glycemic index (GI) diet and a reduced glycemic index diet while keeping the overall caloric intake and fiber intake the same in both groups. The researchers noted that the participants who at the higher glycemic index diet had lower resting energy expenditure (i.e. lower metabolism) than did the reduced glycemic diet group. They also noted that after one week, the group eating the high glycemic diet began to snack more than did the lower glycemic diet group. They concluded that modifying dietary intake to include lower glycemic foods changes our bodies’ adaptation to reduced food intake by preserving our metabolism. They also concluded that the lower glycemic index diet reduced voluntary food intake. |

| High Glycemic Index Foods, Overeating, and Obesity (Journal Abstract) |
Added on: 7/17/2002 | Hits: 105 |
| From Tufts University, the USDA, and the journal Pediatrics, 1999: These researchers studied the effects of feeding overweight adolescent boys low glycemic, medium glycemic, and high glycemic meals. They found that the boys ate 53% more food after the high glycemic meals than after the medium glycemic meals and a whopping 81% more than they ate after the low glycemic meal. The boys who ate the high glycemic meals also had higher insulin levels and lower glucagon levels. They concluded that, "The rapid absorption of glucose after consumption of high GI meals induces a sequence of hormonal and metabolic changes that promotes excessive food intake in obese subjects." |

| High Protein vs High Carbohydrate Hypoenergetic Diet for the Treatment of Obese Hyperinsulinemic Subjects (Journal Abstract) |
Added on: 7/12/2002 | Hits: 95 |
| From Columbia University in New York and The International Journal of Obesity, 1999: These researchers compared two groups of obese hyperinsulinemic men. One groups was placed on a low carbohydraate diet (25%) while the second was placed on a high carbohydrate diet (58%). The low carb group lost more weight. The low carb group achieved normal fasting insulin levels while the high carb group did not. Although both groups lost weight, resting energy expenditure (an indicator of metabolism) decreased more in the high carb group than in the low carb group. The researchers concluded, "A low-carbohydrate, high protein diet could be the diet composition of choice for a weight-reducing regimen in obese hyperinsulemic subjects." |

| Low Glycemic Index Diet Decreases Fat Mass & Improves Plasma Lipids in Overweight Nondiabetic Men (Journal Abstract) |
Added on: 7/11/2002 | Hits: 70 |
| From the AP Hotel-Dieu Hospital in Paris and the journal Diabetes Care, 2002: In this study, French researchers report that a low glycemic diet decreased total body fat, increased lean body mass, and improved blood lipids in overweight males. They concluded that a low glycemic diet could be of benefit in preventing metabolic diseases and cardiovascular complications. |

| Sugar Drinks Rapidly Converted Into Body Fat, Study Shows (Press Release) |
Added on: 7/11/2002 | Hits: 76 |
| From the Royal Veterinary & Agricultural University in Denmark and the North American Association for the Study of Obesity (NAASO), 2002: This study compared two groups of overweight people. One group consumed sugar-filled drinks while the other group drank drinks with artificial sweeteners. After 10 weeks, the group that consumed sugar gained body fat while the artificial sweetener group lost weight and lowered their blood pressure. "This study shows that a diet containing too much sugar can quickly cause weight gain, and the complications associated with weight gain," notes a NAASO spokesperson. |

| Lipogenesis and Metabolic Changes Induced by A High-Carbohydrate, Low-Fat Meal in Lean and Overweight Men (Journal Abstract) |
Added on: 7/11/2002 | Hits: 54 |
| From The University of Navarra in Spain and The American Journal of Clinical Nutrition, 2001: This study concludes that obese people produce more body fat after a high carb meal than do leaner people. These Spanish researchers study documented that after a high carb, low fat meal overweight men had higher insulin levels, higher fatty acid levels, and produced more body fat than did lean men. This study suggests that some people become overweight because they are able to store sugars as body fat more readily. |

| Physical Activity and Dietary Fiber Determine Body Fat Levels: The Seven Countries Study (Journal Abstract) |
Added on: 7/11/2002 | Hits: 83 |
| From the National Institute of Public Health in the Neatherlands and the International Journal of Obesity 2001: These multinational researchers investigated the association between physical activity, dietary fat, dietary fiber and body fat in seven countries. They concluded that physical activity and dietary fiber are important determinants of body fat, but found that dietary fat was not a factor.

| Obesity Has Reached Epidemic Proportions (Press Release) |
Added on: 7/11/2002 | Hits: 46 |
| From the Baylor College of Medicine and the American College of Nutrition, 2000: This Baylor professor reports that obesity in the United States has become so prevalent that it now qualifies as an epidemic. Some of the statistics reported in this study are truly shocking. In the US, 55% of adults and children qualify as being overweight (body weight more than 20% greater than recommend for height and gender). Obesity is now the most prevalent disease of children and young adults. Between 1980 and 1990, the prevalence of obesity in US adults increased by 40%. Among children, obesity has increased by a whopping 64% since 1960 predisposing them to heart disease, stroke, hypertension, cancer, and diabetes. The researcher points out that this dramatic increase occurred in less than one generation and therefore cannot be attributed to changes in genetics. |

| Overweight? Losing Excess Weight is More Important Than Trimming Dietary Fat (Magazine Article) |
Added on: 7/11/2002 | Hits: 93 |
| From the USDA's Agricultural Research Magazine, 2000: This USDA article outlines the results of a study at the Human Nutrition Research Center that documents that overweight men had a bigger drop in triglycerides when eating a diet high in monounsaturated fats than when eating a low fat diet. They also report that high triglycerides were associated with reduced glucose tolerance and concluded that both are risk factors for heart disease. |

| Ever Feel Hungry a Few Hours After a Big Meal? (Magazine Article) |
Added on: 7/10/2002 | Hits: 84 |
| From the USDA Human Nutrition Research Center, 1999: This study was the first solid evidence that carbohydrate foods with a high glycemic index contribute to obesity. In this study, overweight teenage boys were fed high, medium, and low glycemic index meals. The boys ate twice as much food after the high glycemic meals than they ate after low glycemic meals. The researchers concluded that high glycemic meals promote overeating and leads to obesity. |

| Glycemic Index and Obesity (Journal Abstract) |
Added on: 7/10/2002 | Hits: 67 |
| From The University of Sydney, Australia and The American Journal of Clinical Nutrition,2002: In this research statement three Australian researchers cite support for the concept that high carbohydrate intake results in obesity. In this statement,the researchers review studies that support the concept that lower glycemic index foods “…enhance weight control because they promote satiety, minimize postprandial insulin secretion and maintain insulin sensitivity.” They call for more research that compares the effects of ‘conventional’ and low glycemic diets on weight control. |

| Insulin Causes Fatty Acid Transport Protein Translocation and Enhanced Fatty Acid Uptake in Adipocytes (Journal Article) |
Added on: 7/10/2002 | Hits: 32 |
| From Massachusetts Institute of Technology (MIT)and the journal Developmental Cell, 2002: In this complex study, MIT researchers report that insulin plays a crucial role in moving fat from the blood to fat-storage cells after a meal. They conclude that this mechanism "may play an important role in metabolic disorders such as type 2 diabetes." (Requires free site registration.) |

| Fish-Rich Diet Linked with Low Leptin Levels (Press Release) |
Added on: 7/10/2002 | Hits: 45 |
| From The Mayo Clinic and the journal Circulation, 2002: These researchers studies two similar African tribes, one of which ate a vegetarian diet and the other of which ate a diet rich in fish. The researchers found that the group that ate the most fish had lower levels of the hormone leptin, especially among women(leptin is a hormone believed to foster weight gain and heart disease). |

| UT Southwestern Team Isolates Key Protein In Transforming Excess Glucose Into Fat (Press Release) |
Added on: 7/10/2002 | Hits: 39 |
| From University of Texas Southwestern Medical Center at Dallas, 2001: A team of researchers identified a glucose-sensitive protein that translates excessively high-carbohydrate intake into body fat. These researchers state that this protein activates a process when people eat excess carbohydrate that prompts the liver to convert surplus blood glucose to body fat. |
