A new study reveals that living in densely populated neighborhoods can decrease the risk of developing diabetes and obesity. The design of Toronto's neighborhoods, such as Bridle Path-Sunnybrook-York Mills, Edenbridge-Humber Valley, and Morningside, encourage walking and discourage driving, leading to a lower risk of these health issues.
A new peptide treatment has been shown to restore leptin responsiveness, improve body weight and glucose metabolism in obese mice fed a high-fat, high-sugar diet. The treatment overcomes leptin resistance, a major obstacle in treating obesity and type 2 diabetes.

UCSB psychology professor Brenda Major found that weight-stigmatizing messages can actually lead to increased eating and reduced self-control in overweight women. The study suggests that these messages can exacerbate feelings of helplessness, causing individuals to engage in unhealthy eating habits.
Researchers found that adding half an avocado to a lunch reduced participants' desire to eat by 40% over three hours and increased feelings of satisfaction by 26%, compared to a standard lunch. The study's findings suggest avocados may play a role in blood sugar management, leading to further investigation.
A recent study published in the Journal of Neuroscience has discovered a new player in regulating food intake and body weight, providing potential avenues for treating obesity. The research reveals that alpha2/delta-1 facilitates brain-derived neurotrophic factor (BDNF) function, which plays a critical role in appetite suppression.
Researchers found an association between a person's fitness as a teenager and their risk of heart attack in later life. The more aerobically fit men were in late adolescence, the less likely they were to have a heart attack 30 or 40 years later.
A sugar-sweetened beverage tax could mitigate the rise in obesity and type 2 diabetes rates in India by averting millions of cases. The study estimates that a 20% SSB tax would save 11.2 million cases of overweight/obesity and 400,000 cases of type 2 diabetes between 2014 and 2023.

A new study found that slowing down meal pace can lead to reduced hunger and calories consumed in normal-weight individuals. However, the effect was less pronounced in overweight or obese subjects, who may have eaten less due to self-consciousness. Both groups experienced lower hunger levels after slower-paced meals.
