Deakin health expert Professor Boyd Swinburn argues that research funding should focus on testing potential solutions rather than understanding the causes of weight gain. He suggests 'rule-based' approaches, such as dietary rules or policies, may be more effective in preventing obesity and promoting sustainable environmental changes.
Research found that ghrelin hormone increases appetite and promotes the accumulation of abdominal fat, linked to higher blood pressure, type 2 diabetes, and metabolic syndrome. Ghrelin's twin action on the organism opens doors for future treatment of obesity.
Researchers found that wild spider monkeys regulate their daily protein intake similarly to humans, with a focus on maintaining a consistent level regardless of seasonal food availability. This pattern is linked to the development of obesity in humans and may have evolutionary origins dating back far older than previously thought.
A new study found that older people with lower BMI scores are 79% more likely to develop dementia than those with higher BMI scores. Those who lost weight rapidly over eight years were nearly three times more likely to develop dementia, especially if they started out overweight or obese.
Obese heart disease patients tend to respond well to treatment and have better short- and long-term prognosis than leaner counterparts. However, the exact mechanisms behind this phenomenon are still unclear, and more research is needed to understand the relationship between obesity and cardiovascular outcomes.
Researchers found that a high-calorie exercise program involving daily long-distance walking resulted in greater fat mass loss and improved insulin sensitivity compared to standard cardiac rehabilitation. After five months, the high-calorie group showed significant improvements in heart risk factors and weight reduction.
A study found that vibration plate exercise, combined with a calorie-restricted diet, led to significant long-term weight loss and fat reduction. The intervention group lost an average of 10.5% body weight and 47.8 square centimeters of visceral fat, compared to the control group who gained weight.
A new study suggests that US obesity has been largely driven by increased energy intake, rather than reduced physical activity. The research found that if Americans had only consumed their recommended daily calorie intake, they would have gained approximately 10.8 kg less weight.

These policies are most effective in reducing weight disparities among vulnerable populations, including children, adolescents, and low-income individuals.
A study of 900,000 adults found that a body-mass index above the ideal range of 22.5-25 kg/m2 leads to increased mortality rates. Moderate obesity has only one-third the effect on mortality as smoking, while severe obesity has a similar impact but is relatively rare.
Assistant professor Samantha Kwan argues that the concept of obesity has been overstated and is influenced by cultural beauty messages and health discourses. She claims that women are more closely tied to weight and appearance, and that conforming to norms can bring benefits beyond being healthier.
A new study reinforces the importance of healthy living by finding that women with a healthy weight and lower perceived stress may have slower telomere shortening, potentially reducing breast cancer risk. The study suggests that duration of obesity and levels of perceived stress can impact telomere length, accelerating aging.
Research finds that obese women, especially white ones, are less likely to have undergone a recent mammography compared to normal weight women. The study highlights poor self-esteem, body image issues, and racial disparities in obesity-related body image as reasons for the disparity.
A study found that obese patients who underwent pancreatic resection surgery had significantly worse survival rates compared to non-obese patients. The risk of lymph node metastasis and cancer recurrence was also higher in obese patients.
A study by Dr Tom Barber and colleagues found a genetic link between the FTO gene and PCOS susceptibility. The researchers analyzed 463 PCOS patients and 1336 female population controls, discovering that variants of the FTO gene influence fat mass and PCOS-susceptibility.
A study found a widening gap between heart disease guidelines and patients' lifestyles, with doctors prescribing more drugs while lifestyles remain unchanged. Lifestyle interventions are crucial to prevent heart disease, but comprehensive programs are lacking.
A 15-week weight loss program found that obese women who consumed less than 600mg of calcium per day lost nearly 6kg, compared to 1kg for those in the control group. Sufficient calcium intake stiffs desire to eat more, aiding weight loss success.
