Researchers found that teammates and social influence play a significant role in weight loss, particularly in team-based weight loss competitions. Participants who said their teammates played a large role in their weight loss actually lost the most weight. Individual characteristics such as obesity status also affected weight outcomes.
A University of North Carolina at Chapel Hill study found that substituting noncaloric beverages, such as water or diet soft drinks, can lead to significant weight loss. Participants who switched to calorie-free beverages lost twice as much weight and had lower fasting glucose levels compared to those who did not make a change.
A Marshall University researcher has received a $60,000 grant to investigate the connection between obesity and cancer. The study aims to understand why obesity increases human risk for several types of cancers.

A study analyzing human gut microbes as a complex system reveals patterns corresponding to excess body weight. The researchers found organizational shifts away from a normal state in the gut flora of obese individuals, which may account for their increased energy extraction capacity.
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 penny-per-ounce tax on sugar-sweetened beverages could reduce consumption by 15% and result in an estimated savings of $17 billion in healthcare costs over a decade. The tax would have the greatest impact among younger adults and men, leading to significant reductions in obesity-related health problems.

This discovery opens up therapeutic avenues for the genetic disorder.
A large study showed that obese patients have poorer long-term outcomes than normal-weight patients when not treated with trastuzumab. Adding trastuzumab to treatment may potentially equalize disease-free survival rates among all patient groups.
A study by Mayo Clinic researchers found that obese patients with HER2-positive breast cancer had poorer outcomes, larger tumors, and were more likely to have lymph node involvement compared to normal-weight patients. The study's lead author notes that excess body weight may affect treatment outcome for this subtype of breast cancer.
Research found obesity associated with shorter time to recurrence and disease-free survival in early-stage breast cancer. However, treatment with endocrine therapy showed a protective effect against obesity-related poor outcomes.

This discovery sheds light on the potential link between ciliopathies, such as Bardet-Biedl syndrome, and obesity.
A University of Illinois survey found that Mexican college applicants who were physically active reported more conflict about exercise at home than those who were not. The study suggests that parents' cultural beliefs and attitudes towards physical activity can be a significant barrier to teens' engagement in regular exercise.
A recent study found that resting muscle sympathetic nerve activity (MSNA) is a significant independent predictor of weight-loss outcome in overweight or obese subjects. Successful weight losers demonstrated large increases in nerve activity following a carbohydrate test meal.
