A study found that pregnant women exposed to high levels of common household chemicals PFCs had babies that were smaller at birth and heavier by 20 months, potentially leading to obesity later in life. The research suggests a link between prenatal exposure to PFCs and increased risk of weight gain in childhood.
A study by Cornell Food & Brand Lab found that softening fast-food restaurant lighting and music reduces calorie intake by 18% and increases customer satisfaction. Diners ate 175 fewer calories and rated the food as more enjoyable in a softer environment.
Research suggests that loss of daily rhythms can cause obesity, as our bodies struggle to stay in tune with irregular meal, sleep, and work schedules. Disrupted circadian desynchrony affects brain systems regulating metabolism, increasing the risk of developing obesity and diabetes.
Scientists have decoded signals that boost the burning of fat, focusing on the conversion of white fat cells into beige fat cells. Beige fat cells are efficient at converting energy from food into heat and can form from white fat cells.

This similarity suggests that habitual metabolic rates are relatively constant among human populations.
Two studies published in the Journal of Bone and Joint Surgery found that high blood sugar and obesity significantly increase the risk of surgical site infections after orthopaedic trauma and total joint replacement. Nearly one-third of hospital admissions without diabetes have hyperglycemia, which is associated with longer stays, ICU ...
Global food output has doubled in the past half-century, yet hunger and malnutrition continue to plague the world's poorest populations. The researchers propose an ambitious plan to remake the way food is grown, processed, distributed, sold, and consumed, focusing on innovations that take into account farmers' needs, nutrition-related ...
Researchers have developed a new body shape index (ABSI) that combines BMI and waist circumference to predict mortality hazard independently of BMI. The study analyzed data from over 14,000 US adults, finding ABSI to be strongly correlated with death rate.
Research from Drexel University School of Public Health found that obese individuals with low vitamin D levels had insulin resistance 32 times more common than the general population. The combination of obesity and vitamin D deficiency may put people at a greater risk of developing Type 2 diabetes.
A new study examining the health-care expenditures after bariatric surgery found no significant association between the procedure and reduced healthcare costs. The research suggests that trends in adjusted total expenditures mirrored those of outpatient and inpatient expenditures.
Research suggests that sleep behavior affects body weight control and that sleep loss has ramifications for how many calories we consume and burn off through physical activity. Sleep deprivation increases hunger and reduces physical activity, leading to weight gain and increased risk of obesity and type 2 diabetes.
Research suggests that adding words related to health and weight on posters, menus, or recipe cards can stimulate healthy food choices among dieters and overweight individuals. This technique has great potential as an intervention to help weight control, as it is unobtrusive, easy to implement, and low in cost.

The researchers used objective and subjective methods to track the frequency of hot flashes, finding that exercising actually reduced symptoms in most participants, contradicting previous assumptions.
Obese appendectomy patients who undergo minimally invasive laparoscopic procedures experience fewer complications, longer hospital stays, and higher rates of infectious complications compared to open appendectomy. This study suggests that minimally invasive operations may be less risky for obese patients, reducing morbidity by up to 57%.
A stepped-care approach to weight loss resulted in clinically meaningful weight loss with lower costs compared to a standard behavioral weight loss intervention. The study found that the stepped-care intervention was more cost-effective, with a mean cost per participant of $358 compared to $494 for traditional programs.
A new study suggests that viewing images of high-calorie foods stimulates the brain's appetite control center, leading to increased desire for food. The research found that this stimulation may contribute to overeating and obesity, particularly in high-risk populations such as Hispanic young women.
The US Preventive Services Task Force recommends that clinicians screen all adult patients for obesity and offer intensive behavioral interventions. While medium- to high-intensity counseling produced small short-term improvements in cardiovascular health, the task force concludes that these interventions are more effective when delive...
USC researchers found that viewing pictures of high-fat foods stimulates appetite and reward centers in the brain, increasing hunger and desire for certain foods. Consuming sugary drinks also increases desire for savory foods, particularly fructose.
A new animal study finds that oxytocin helps regulate food intake and energy metabolism without causing adverse effects. Oxytocin administered through daily injections or implanted mini pumps reduced food consumption, body weight, and liver fat, improving glucose tolerance and reducing abdominal fat.
Research found that SFRP5-deficient mice showed increased metabolic activity and were resistant to diet-induced obesity, revealing the mechanism of SFRP5-mediated fat cell generation. The study suggests targeting the WNT signaling pathway could be a therapeutic approach to treat obesity.
Scientists identify WNT signaling pathway as potential therapeutic target for obesity. Antibiotic treatment after Lyme disease shows fluorescent bacterial debris remains without causing infection. Oxidative stress contributes to parasite persistence in host tissues, opening new avenue for anti-Trypanosoma cruzi drugs.
A new study found that weight loss reduced the prevalence of low testosterone levels in overweight, middle-aged men with prediabetes by almost 50 percent. The study involved nearly 900 men and showed that lifestyle modification, rather than medication, can increase testosterone production.
