Obesity
Replacing soft drinks with water may equal weight loss
A Dutch study found teens who swapped sugary drinks for water did not compensate by eating more snacks. In a USC study of 54 overweight Latino adolescents, those who cut back on sweet drinks had healthier blood sugar, and many also ate more fiber and lost visceral fat.
Nutrition
Grape seed extract helps prevent obesity
Hamsters at the University of Montpellier fed a high-fat diet plus Chardonnay grape seed extract for 12 weeks did not gain the abdominal fat seen in high-fat controls, and were partly spared rises in blood sugar, triglycerides, insulin and insulin resistance.
Obesity
Limiting fructose may boost weight loss
Elizabeth Parks of UT Southwestern reports in the Journal of Nutrition that people turn fructose into body fat surprisingly fast, and that cutting fructose may be one reason low-carbohydrate diets work. Which carbohydrates you eat may matter as much as how many calories.
Obesity
Low carb diet effective at helping weight loss for a short term
A two-year trial of low-carbohydrate, low-fat and Mediterranean diets produced no more than about 10 pounds of weight loss despite tight calorie control and counselling, with the low-carb diet doing best. An editor's note cautions those dieters were steered toward vegetarian fat and protein.
Obesity
Not all sugars have an equal effect on obesity
Peter Havel's team at UC Davis reported that overweight and obese people who took about 15 percent of calories as pure fructose for ten weeks gained 1.5 kilograms and added intra-abdominal fat. A glucose group gained the same weight but not the deep belly fat.
Obesity
Eating a carb-rich breakfast helps lose more weight
In a study of 94 obese, inactive women, those who ate a big high-carb breakfast lost more weight over eight months than strict low-carb dieters, who regained 18 pounds. Lead author Daniela Jakubowicz says very low-carb diets worsen carb cravings and slow metabolism.
Obesity
Prenatal diet affects onset of puberty
In a rat study presented at the Endocrine Society meeting, pups whose mothers ate a high-fat diet reached puberty earlier and carried more body fat later, even when they themselves ate normally. Researcher Deborah Sloboda said the fetal environment may matter more than childhood nutrition.
Obesity
Grapes' resveratrol may help prevent obesity
In lab tests on human pre-fat cells, University of Ulm researchers found resveratrol kept the cells from multiplying and maturing, hindered fat storage, lowered interleukins 6 and 8 and raised adiponectin. A coauthor cautioned that knowledge is still limited.
