Research from the Children of the 90s study at the University of Bristol shows that most babies who are slow to put on weight in the first nine months of life have caught up to within the normal range by the age of 13. However, those who show slow weight gain later in infancy tend to remain lighter and shorter than their peers.
A study found that obese pregnant women who followed a healthy lifestyle program were more likely to stay within the recommended weight gain limit, with a lower risk of hypertension, preterm delivery, and gestational diabetes. The program included a 1500 kcal/day diet and mild physical activity.
Researchers found that African-American women with pre-pregnancy obesity and excess weight gain during pregnancy are more likely to have macrosomia, or newborns weighing over 4,000 grams. This increased risk is linked to energy accumulation by the fetus from increased maternal glucose concentrations and insulin resistance.
A new study by Brown University found that Samoan babies experience rapid weight gain in early infancy, which may foreshadow a future trend of obesity in developed nations. The researchers tracked the growth and weight gain of nearly 800 American Samoan babies born between 2001 and 2008.
A study found that overweight and obese individuals are gaining weight rapidly in low-and middle-income countries, while those who are severely undernourished are not experiencing similar weight gains. This growing divide may force governments to balance priorities between addressing health issues afflicting the underweight and the obese.

The research controlled for various confounding factors, including genetic and environmental influences, to separate the effect of gestational weight gain on cognition.
A recent study by researchers at St. Michael's Hospital reviewed over 40 published studies on fructose and its link to obesity. The findings suggest that it may not be the fructose molecule itself causing weight gain, but rather consuming too many calories from any food source.
A 6-month program involving weekly peer meetings, consultations with primary care providers, and family meals resulted in less weight gain, improved body image, and healthier habits among teenage girls. The study, funded by the National Institutes of Health, showed modest but significant weight changes compared to usual care.
A new study found that weight gain and dietary changes are not effective in preventing repeat preterm birth. Women who have had a prior preterm birth should follow standard weight gain guidelines during their second pregnancy to minimize risk.
Researchers found that obese individuals' brains exhibit altered glucose metabolism in reward regions, leading to increased food cravings. The study suggests the brain plays a crucial role in obesity and weight gain, highlighting potential for new treatments.
The study sheds light on how calorically dense foods influence brain regions that regulate body weight, leading to increased food intake and weight gain. By understanding this mechanism, scientists aim to develop interventions that work with the body's biology to reduce obesity rates.
A study published in the Journal of Women's Health found that young women are more likely to recognize weight gain if they are black or using DMPA. The researchers surveyed 466 women with an average age of 25, finding nearly one-third and one-quarter did not recognize gains of 4.5 and 8.8 pounds during a six-month interval.
A 6-week program called Mindful Restaurant Eating helps develop skills to reduce caloric and fat intake when eating out. Participants lost significantly more weight and had lower daily caloric intake after completing the intervention.
A study of 25 healthy individuals found that consuming a low-protein diet resulted in less weight gain compared to normal and high protein diets, with calories alone contributing to an increase in body fat. Protein intake also affected energy expenditure and lean body mass.
A new study found that both pre-pregnant weight and weight gain during pregnancy are important predictors of babies' birthweight. Women with higher education levels had the highest offspring birthweight, highlighting the importance of a healthy weight before conception and moderate weight gain during pregnancy.
Women who practiced stress reduction and mindful eating had greater reductions in deep belly fat, associated with an elevated risk for heart disease or diabetes. Mindfulness techniques helped prevent weight gain even without dieting.
A 15-minute walk can cut snacking on chocolate at work in half, regardless of task difficulty or stress levels. Researchers found that employees who took a short break consumed an average of 15g, equivalent to a small 'treat size', compared to 28g for those who didn't exercise.
Research by Paul Williams found that certain risk factors, such as lower education level and high meat/low fruit diets, become stronger for those with a higher BMI, contributing to accelerated weight gain. This phenomenon may explain the recent increase in obesity rates in Western societies.
Scientists engineer mice to express human enzyme IKKbeta in fat tissue, significantly slowing weight gain and improving metabolism. The study suggests obesity is worse than inflammation for insulin resistance, offering new clues about the connections among obesity, inflammation, and type 2 diabetes.
