Story highlights Artificial sweeteners may contribute to weight gain long-term Studies linking artificial sweeteners to cancer have been refuted (CNN)Could the no-calorie sweetener you rely on to replace sugar in your diet actually cause weight gain instead of the weight loss you were expecting? The answer may be yes, according to a new study. "Artificial sweeteners are not risk-free," said Brian Hoffmann, assistant professor in the Department of Biomedical Engineering at the Medical College of Wisconsin and Marquette University, and a lead author of the study. "They are a very controversial topic when it comes to health and nutrition ... but they're so prevalent in society that I think we owe it to ourselves to try and figure out what's actually going on." Hoffmann presented his new research Sunday at the annual Experimental Biology meeting in San Diego. Relying on rats and human cell cultures, his team identified a number of pathways linking artificial sweeteners with … [Read more...] about Can artificial sweeteners cause weight gain?

Abstract BackgroundPrevious research has examined the role of early-life risk factors on childhood weight gain.The extent to which these factors drive socioeconomic differences in weight is unclear. We aimed to quantify the influence of early-life risk factors on the development of socioeconomic inequalities in children’s body mass index (BMI) z-score at 10–11 years.MethodsOverall, 2186 children from the Longitudinal Study of Australian Children were examined. Socioeconomic position (SEP) was measured as a continuous composite of parent’s education, occupation and income. The Product of Coefficients mediation method was used to quantify the contribution of maternal smoking during pregnancy, gestational diabetes, prematurity, caesarean section, birthweight, not being breastfed, early introduction of solid food, maternal BMI and paternal BMI to the relationship between SEP and BMI z-score.ResultsEach increasing decile of SEP (higher SEP) was associated with a 0.05 unit … [Read more...] about Influence of early-life risk factors on socioeconomic inequalities in weight gain
(Natural News) According to scientists, “winter weight gain” could be partly caused by a lack of sunlight exposure during winter.Researchers from the University of Alberta have announced that the according to the results of their study, the fat cells under our skin shrink once exposed to the “blue light” emitted by the sun.Peter Light, the senior author of the study, said, “When the sun’s blue light wavelengths — the light we can see with our eye — penetrate our skin and reach the fat cells just beneath, lipid droplets reduce in size and are released out of the cell. In other words, our cells don’t store as much fat.”Light, who is a professor of pharmacology and the director of UAlberta’s Alberta Diabetes Institute, explains that the fact that individuals who live in a northern climate are not exposed to enough sunlight eight months in a year could be the reason for winter weight gain.The professor cautions … [Read more...] about Why do we gain weight in winter?

Research by scientists has revealed that some foods may have an impact on appetite. These could be beneficial for weight loss when incorporated into a healthful diet and lifestyle. Read on to learn more about seven foods that may be helpful for weight loss. People should buy nutrient-dense foods if they are trying to lose weight. Foods that provide protein and fiber could be especially helpful for weight management. One study found that some foods — including fruits, vegetables, nuts, whole grains, and yogurt — were connected with weight loss. In the same study, potato chips, sugary beverages, red meats, and processed meats were associated with weight gain. Based on these findings, it may be best to limit fried foods, foods with added sugar, high-fat meats, and processed foods when trying to shift the pounds. Though the right foods may help, physical activity is essential for losing weight and keeping the pounds off. It is important to check with a doctor before starting … [Read more...] about What are the best foods for weight loss?
Despite our best efforts to remain thin, it seems that during the holiday season, we put on a lot of weight. Why is that? A new study has a surprising answer. Plenty of us are familiar with the holiday weight phenomenon. But while it is true that during the holidays we're more exposed to delicious food than the rest of the year, some studies have shown that in winter, we continue to pack on the pounds despite conscious efforts to lose them. Why? A new study — by researchers at the University of Alberta in Edmonton, Canada — reveals an unexpected culprit for winter weight gain: the absence of sunlight. The researchers, who were led by the auspiciously named Peter Light — from the Alberta Diabetes Institute — examined the effect of sunlight on subcutaneous fat cells, or white fat cells that can be found right beneath our skin. The results of their investigation make this a breakthrough study, and it was recently published in the journal Scientific Reports. Light … [Read more...] about Weight loss breakthrough: Sunlight is key
