A study of over 33,000 people found that preventing adult weight gain can reduce type 2 diabetes cases twice as much as targeting high-risk individuals, and that population-based strategies could prevent nearly one in five diabetes cases if everyone who gained weight maintained their weight.
Researchers followed adults in five countries and found no association between physical activity and weight gain. However, weight at the initial visit, age, and gender were significantly associated with weight change. The study provides new evidence that exercise is not a reliable method for controlling weight.
A new study published in the Society for Maternal-Fetal Medicine's annual meeting found that a weight loss intervention did not improve pregnancy outcomes despite reducing maternal weight gain. The study, MOMFIT, tested an intensive lifestyle behavioral intervention to help overweight and obese women limit gestational weight gain.
Researchers from Ruhr-Universität Bochum used data from the Astrophysical Journal to determine the age of the star, finding it had formed at the same time as our galaxy. The dual star system's companion star transferred matter to 49 Lib, causing incorrect age estimates.
A study found that children perceived as 'overweight' by parents tend to gain more weight over time, possibly due to negative self-image and attempts to lose weight. The association was seen in both Australian and Irish families, with the link not explained by other factors.
A study in obese mice reveals that physical inactivity is linked to altered dopamine receptors, contradicting the assumption that excess body weight is the primary cause. The research suggests that dopamine signaling defects contribute to reduced movement in obesity.
A study published in Physiology & Behavior found that desirable taste determines food choice but not consumption volume. Researchers fed mice tasty human foods and discovered they didn't gain excess weight despite strong preference for these diets.
A new study published in the Journal of Nutrition Education and Behavior found that college students experience significant weight gain, averaging around 10 pounds over their four-year college career. This excessive weight gain is associated with an increased risk of health problems, including diabetes and hypertension.
Researchers at Weizmann Institute of Science found that gut microbes contribute to recurrent 'yo-yo' obesity, with a 'memory' of previous obesity retained after dieting. They developed new treatments using fecal microbiome transplantation and flavonoids, which may help alleviate the obesity epidemic.
Repeated dieting can cause weight gain as the brain interprets diets as short famines and urges people to store more fat for future shortages. This phenomenon, known as yo-yo dieting, may explain why people struggle to keep weight off after trying low-calorie diets.
Women who are overweight or obese are less likely to use hormonal birth control methods, opting for long-acting reversible contraceptives (LARCs) like IUDs and implants instead. This preference is driven by fear of weight gain associated with the pill and shot, despite LARCs not containing estrogen.
A new study published in Pediatrics found that children who skip breakfast and have irregular sleep patterns are more likely to become overweight or obese. The research, based on data from over 19,000 UK children, highlights the importance of early life factors such as smoking in pregnancy and disrupted routines in predicting weight gain.
Researchers found that substantial weight gain increases the risk of obesity-related cancers, particularly for men who go from a healthy weight to morbid obesity. The study suggests that identifying people at high risk of developing cancer due to weight gain could help prevent cases and improve public health.

Sedentary rats experienced a 50% reduction in fat tissue after limited physical activity, highlighting the benefits of any amount of exercise.
A recent study published in the New England Journal of Medicine found that individuals tend to gain weight between Thanksgiving and Christmas, with a peak around the New Year. By setting an October weight resolution, individuals can avoid gaining holiday weight altogether, as it may take over 5 months to lose gained pounds.
A small study found that smoking decreases dietary intake by reducing ghrelin levels, a hunger hormone. This effect can help explain why current smokers are less likely to be obese than non-smokers.
A clinical trial found metformin to be effective in reducing weight gain associated with atypical antipsychotics in children and adolescents with autism spectrum disorder. The study, published in JAMA Psychiatry, suggests that metformin may offer a potential treatment option to mitigate the risks of diabetes linked to weight gain.
Researchers found that metformin effectively reduced body mass index scores in overweight children and adolescents with autism spectrum disorder who take antipsychotic medications. The double-blind clinical trial also showed metformin was well-tolerated and did not cause behavioral changes.
A Penn State researcher found that pregnant women use a dual self-image to cope with the physical and emotional changes of pregnancy. They differentiate between their pre-pregnancy body weight and 'baby weight,' allowing them to maintain a positive body image during this time.
A study published in the Maternal and Child Health Journal found that abnormalities in interval between pregnancies, body mass index prior to pregnancy, and weight gain during pregnancy may contribute to up to 25% of preterm births. Modifying these risk factors could significantly reduce premature birth rates worldwide.
A recent study on 'The Biggest Loser' television series found that participants regained much of the weight they lost, with suppressed metabolism. Experts say a 5-15% weight loss is unlikely to lead to such large effects on metabolism and emphasize the importance of long-term lifestyle changes.

A Cincinnati Children's Hospital Medical Center study found that Zyprexa (olanzapine) is linked to the highest risk of weight gain, while Geodon (ziprasidone) and Seroquel (quetiapine) were not associated with an increase in body mass index. The study suggests balancing treatment risks and benefits for children and teens with ASD.
A new study from McMaster University found that lifting lighter weights many times can be as efficient as lifting heavy weights for fewer repetitions in building muscle and strength. Researchers analyzed muscle and blood samples and found gains in muscle mass and fibre size were virtually identical between the two groups.
A new study suggests that a powdered food supplement, based on a molecule produced by bacteria in the gut, can reduce cravings for high-calorie foods like chocolate and pizza. The supplement, called inulin-propionate ester, releases more propionate than other fiber supplements, which signals to the brain to reduce appetite.
Researchers suggest that anorexia nervosa is linked to the brain's reward system and a genetic factor involved in neuron survival. The study found that patients with anorexia nervosa experience increased sweating when viewing images of thin bodies, which may be related to the presence of a specific gene variant.
A Swedish study found that mothers who gained 4 kg/m2 or more between pregnancies had a higher risk of low Apgar scores, neonatal seizures, and meconium aspiration. Preventing weight gain could reduce birth asphyxia and improve infant health.
In a study published in Nature, researchers found that subordinate female meerkats track the growth of potential competitors and adjust their own weight gain to stay ahead. The results suggest that competitive growth is a key strategy for social mammals to maintain dominance.
Researchers at McGill University have discovered a crucial role of NG2-glia cells in the median eminence in regulating appetite and body weight. The cells support and shelter leptin receptor neurons, enabling them to instruct the body when to stop eating, leading to potential new targeted anti-obesity approaches.
A large study published in The BMJ found that people with a heavy body shape from childhood to middle age have the highest mortality rate. Those who remained lean throughout life had the lowest mortality risk, with a 15-year risk of death being 11.8% in women and 20.3% in men.
Researchers found that young adults taught to weigh themselves daily and make small changes in diet and exercise had significantly reduced average weight gain over three years. The large change strategy led to even more effective weight loss results.
A study published in JAMA Internal Medicine found that young adults who made small dietary changes and engaged in regular physical activity successfully prevented weight gain. The 'small-change' group lost an average of 1.2 pounds over two to three years, while the 'large-change' group lost nearly 5.2 pounds.
A Kaiser Permanente study found that pre-pregnancy obesity and excessive weight gain during pregnancy increase the risk of a child becoming overweight at age 2. However, breastfeeding for at least six months was associated with a significant reduction in this risk, regardless of the mother's pre-pregnancy weight.
Researchers found that parental perceptions of a child's weight status are not protective against weight gain during childhood. Children whose parents perceived their weight as 'overweight' gained more weight over time. This association holds true even if the parent accurately or inaccurately believed their child was overweight.
A study at Oregon State University has identified a specific intake level of xanthohumol that significantly improves metabolic syndrome markers and reduces weight gain in laboratory animals. The findings suggest a possible new approach to addressing obesity, high cholesterol and elevated glucose.
A new study finds that toddlers who reach for sweet treats after a filling meal are at a greater risk of weight gain. Researchers from Michigan Medicine found that eating in the absence of hunger is associated with being overweight among young children.
A new study found that those who lose more weight are most likely to keep it off, but also experience weight cycling. Patients who lost high percentages of their initial body mass index (BMI) were more likely to maintain their weight loss over time.
African-American infants who feed more vigorously at 1 month of age have higher weight at 4 months, a potential early indicator of obesity risk. Researchers found that stronger sucking skills were associated with greater weight gain from birth to 4 months.
Despite weight gain, smoking cessation reduces cardiovascular risks among patients with serious mental illness. The study found that those who remained abstinent had a lower Framingham Risk Score than those who relapsed, indicating continued risk due to worsening obesity and diabetes.
A study of nearly 40,000 children found no significant association between early-life antibiotic exposure and childhood weight gain. The research suggests that limiting antibiotic use in young, healthy children is not necessary to prevent weight gain.
A study published in SLEEP found that sleep deprivation amplifies the joy of eating, particularly sweet and salty high-fat snack foods. Sleep-restricted participants ate nearly twice as much fat as those with normal sleep, despite minimal energy needs.
A new study published in Nutrition and Diabetes journal found that low-carbohydrate, high-fat diets can lead to rapid weight gain and worsen glucose intolerance. The research suggests that fad diets like Paleo may not be suitable for people with pre-diabetes or diabetes.
A recent study found that adults who took vacations gained an average of nearly 1 pound during their trips, with some participants gaining as much as 7 pounds. The study suggests a trend of 'creeping obesity' where small weight gains over time can lead to increased health problems.
A study found that both short and long sleep durations in pregnancy are associated with extreme gestational weight gain. Poor sleep has been linked to adverse pregnancy outcomes, and the study provides a potential mechanism for this association.
New research reveals that exercise alone is insufficient for weight loss due to the human body's adaptive response. A study published in Current Biology found that daily energy expenditure increases with moderate physical activity but plateaus at higher levels.
A recent study published in The BMJ found that increased flavonoid consumption was associated with less weight gain. The largest association was seen for anthocyanins, flavonol polymers, and flavonols, with daily intake linked to a reduction of 0.16-0.23 lbs (0.07-0.10 kg) over four-year intervals.
A year-long intervention in 21 Australian towns showed a significant reduction in weight gain among women, with an average loss of nearly 0.44 kg compared to +0.44 kg in the control group. The study suggests that simple health messages can be an effective strategy for preventing weight gain in rural communities.
A study published in PLOS ONE found that phthalates, commonly used in plastics, can lead to weight gain by disrupting hormone balance and metabolism. The researchers discovered that the phthalate DEHP causes an increase in unsaturated fatty acids and disrupts glucose metabolism, paving the way for weight gain.
A QUT study published in PLOS ONE found that moderate intensity light exposure earlier in the day is associated with increased body mass index (BMI) in preschool children. The research also discovered that children who received more total light exposure at age 3 had higher BMI 12 months later.
A University of Exeter study found humans have limited ability to avoid becoming obese, especially in winter. The research suggests that the urge to maintain body fat is stronger in winter when food is scarce.
Researchers found that stroked calves gained weight faster, weighed more at 90 days, and had lower avoidance distances, indicating a stronger human-animal relationship. Disbudding without anesthesia disrupted this bond.
A study published in Pediatric Obesity found that waiting 30 seconds between bites of food can help children realize they're no longer hungry and prevent overeating. The slow eating approach resulted in significant weight loss among participants, with some students losing up to 5.7% of their initial weight after six months.
A University of Iowa study found that changes in the gut microbiome can cause obesity by reducing the resting metabolic rate, leading to weight gain. The researchers discovered a significant decrease in non-aerobic resting metabolic rate sufficient to account for the animals' weight gain.
Psychologists have determined the amount of weight required to make a difference in facial adiposity perception. Women need to lose about twice as much as men to be considered more attractive. A change in BMI of approximately 1.33 kg/m2 is required for noticeable changes.
New research involving over 450,000 Swedish women found that mothers who gained a moderate amount of weight between their first and second pregnancies increased the risk of their baby dying in its first year of life. Weight loss before pregnancy also reduced the likelihood of neonatal death in babies of overweight women.
Achieving a healthy weight before becoming pregnant significantly reduces the risk of infant death in the first year of life. Gaining an appropriate amount of weight during pregnancy also plays a crucial role in infant mortality.
A study by Cornell Food & Brand Lab found that healthy-weight individuals tend to eat nutritious breakfasts including fruits and vegetables. The research revealed that egg consumption was higher than expected among slim people, highlighting the importance of breakfast in weight management.
Dr. Christine Olson, a renowned expert in fetal-maternal nutrition, has been named the March of Dimes Agnes Higgins honoree. Her research has provided critical information on the risks of excessive weight gain during pregnancy and its impact on baby health.
Research found that excessive gestational weight gain during pregnancy is associated with greater body fat and weight seven years after delivery, particularly among women who begin pregnancy at normal or slight overweight. The study suggests that these women may need additional support to gain weight appropriately during pregnancy.
Researchers discovered that long-distance migrants stay longer at refueling sites and gain weight faster than short-distance birds. This information can inform conservation strategies to mitigate habitat losses and protect shorebird populations.
