A new Northwestern Medicine remote weight-loss program, Opt-IN, helped participants lose 11-13 pounds, matching the success rate of the gold-standard National Diabetes Prevention Program. The program is cheaper and less burdensome than traditional treatments, making it more accessible and affordable.
Infants who are fed in the absence of hunger or beyond fullness may develop skewed perceptions of hunger and fullness, increasing their risk of obesity. Caregiver-infant interactions during feeding can shape infants' self-regulation of energy intake, with feeding responsiveness to cues being linked to obesity.

A recent study found that consuming calories later in the day can worsen glucose tolerance and reduce fat burned. The effects were more pronounced in people with obesity or diabetes, who already have compromised metabolism.
Experts argue the food industry is responsible for the severity of COVID-19 and the obesity pandemic. The industry's promotion of unhealthy foods has exacerbated the issue, particularly in low-income communities. Researchers call on governments to force reformulation of unhealthy foods and the industry to stop promoting them.
Researchers found BAM15 boosts energy burning, preventing weight gain and fat buildup, while reducing blood sugar levels. The compound also improves insulin sensitivity and restricts fat accumulation in the liver, kidney, and blood.
A UT Southwestern study found that obesity patients faced significant health challenges during the pandemic, including difficulties with diet and exercise, anxiety, and depression. The study's findings highlight the need for effective strategies to minimize the physical and psychosocial impacts of COVID-19 on adults with obesity.
A recent study found that nearly 73% of patients with obesity experienced increased anxiety, while 84% reported depression. The pandemic disrupted their access to healthy food and exercise opportunities, leading to increased stress eating and decreased physical activity.
A systematic review and meta-analysis found that individuals with sarcopenic obesity had a similar prevalence of metabolic syndrome as those without sarcopenia. The study also did not detect an association between the presence of sarcopenic obesity and an increased risk of metabolic syndrome.
Women with non-alcoholic fatty liver disease (NAFLD) in pregnancy face increased risks of maternal and infant health complications. The study found that NAFLD is associated with hypertensive complications, preterm birth, and maternal bleeding after delivery, independent of other metabolic diseases.

A Penn State study found that eating a meal with six grams of spice blend reduced inflammation markers compared to meals with less or no spices. The researchers discovered anti-inflammatory properties in the blend, which may help offset inflammation caused by high-carb and high-fat meals.
A UBC scientist has identified a gene called ALK that plays a role in resisting weight gain in humans. The study found that a mutation in the ALK gene is associated with thinner individuals, and that deleting the gene in mice made them resistant to diet-induced obesity.
A new Swedish study found no correlation between obesity and the distance to fast food restaurants or gyms, contradicting previous research. The study also showed a significant association between neighborhood deprivation and obesity.
The study found that women who watched videos of themselves and their peers experienced increased autonomous motivation and self-efficacy, leading to a significant decrease in fat intake. The intervention's emphasis on coping self-efficacy also reduced participants' stress levels.
A Baylor University study found that exposure to obesogens, chemical compounds disrupting normal metabolic processes, can lead to increased susceptibility to weight gain across the lifespan. The study highlights the potential effects of chemicals in consumer products on lipid-related diseases, including obesity and fatty liver disease.

Analysis of data from 147 countries found a strong association between rising incomes and increasing obesity rates, with an average increase in obesity rates for every 1% rise in GDP per capita. The study suggests that policy initiatives may be necessary to combat obesity in low- and middle-income countries undergoing income growth.
Experts recommend prioritizing surgical treatment for patients with type 2 diabetes or severe obesity due to the risk of complications from their disease and COVID-19. Bariatric and metabolic surgery can lead to significant weight loss, reduced cardiovascular risk, and improved survival.
