What recent discovery was made by researchers at the University of São Paulo regarding a hormone related to obesity?

Researchers at the University of São Paulo discovered that the hormone adiponectin, which is secreted by adipose tissue, can help reverse obesity-related damage in pancreatic cells and improve insulin production. The study suggests potential for developing new treatments for obesity.

What strategies are recommended for individuals to address excess weight or obesity?

Recommended strategies include reducing or eliminating foods with added sugars and saturated fats, increasing the intake of fruits, vegetables, and legumes, and engaging in physical activities, preferably with guidance from a professional.

Public policies are crucial in tackling obesity as they can influence environmental factors, such as the availability of safe spaces for physical activities, and impose taxes on unhealthy food products. These policies help make healthier choices more accessible to the population.

How does the hormonal system affect weight loss and weight regain?

When weight is lost, changes in the hormonal system, such as increased production of the hunger hormone ghrelin and reduced signals of satiety from the gastrointestinal tract, make it difficult to maintain weight loss. This contributes to weight regain despite ongoing efforts to manage weight.

What is the predicted prevalence of obesity in Brazil by 2035?

According to the World Obesity Federation’s Atlas, it is estimated that by 2035, 4 out of 10 adults in Brazil will face obesity or overweight issues, driven by factors such as the impact of climate change, restrictions during the COVID-19 pandemic, and unhealthy food promotions.
