These standards will help identify signs of under-nutrition, stunting, wasting, and overweight in newborns, enabling early intervention to reduce long-term health problems.
A recent study analyzing bariatric surgery data in Michigan reveals a significant shift towards sleeve gastrectomy (SG) as the most commonly performed procedure. SG became the predominant bariatric surgery procedure for patients with type 2 diabetes and its use increased by 61% between 2008 and 2013.
A meta-analysis of nearly 50 trials involving over 7,300 individuals found that low-carbohydrate or low-fat diets resulted in significant weight loss, with minimal differences between individual diet programs. The study suggests that patients can choose a diet that suits their needs and preferences for optimal weight loss.

The intervention was also associated with fewer serious adverse events compared to traditional bariatric surgery.
Bariatric surgery has been shown to prolong life and prompt reductions in weight and associated conditions like diabetes and heart attacks. However, the long-term effectiveness of different procedures is unclear, and more research is needed to standardize reporting and design trials.
A low-carbohydrate diet is more effective than a low-fat diet in reducing body weight and cardiovascular risk factors. The study found that participants on a low-carb diet experienced greater decreases in weight, fat mass, and other cardiovascular risk factors compared to those on a low-fat diet.
A diet of junk food reduces rats' preference for novel foods and leads to overeating and obesity. Researchers found that the brain's reward circuitry is affected by excessive consumption of junk food.
A new study found that weight loss surgery can improve cognitive function and reduce altered brain activity associated with obesity. Bariatric surgery may contribute to a reduced risk of Alzheimer's disease in obese people, according to researchers.
Researchers found that high insulin levels foster processes leading to obesity, even in mice given insulin to counter diabetes. Suppressing glucagon action may prevent hyperinsulinemia without causing diabetes.

Those in the intensive lifestyle intervention group had fewer hospitalizations, shorter hospital stays, and used fewer prescription medications.
Research reveals that being obese in one's 30s triples the risk of developing dementia later in life. The study found an incremental decrease in dementia risk with age, suggesting that weight loss or delayed onset of obesity may lower the risk of dementia.
Researchers found that post-menopausal women with higher levels of physical activity had a lower risk of developing atrial fibrillation, regardless of their weight status. The study's lead author notes that more physically active women were less likely to develop the condition.
A new study from Concordia University reveals that financial struggles significantly impact weight loss efforts, with lower-income individuals less likely to engage in healthy habits like exercise or reducing fat intake. Instead, they often turn to quick fixes like diet pills or skipping meals.
A UK study published in the BMJ Group reveals a significant association between active commuting methods (walking, cycling, or using public transport) and lower BMI scores. For men, this equates to a difference of nearly half a stone in weight, while for women, it's around 5.5lb, compared to those who used private transport.
A study on Chinese adults found that obese male manual laborers experience wage disparities compared to obese female workers and professionals. The researchers also discovered that increasing body weight is associated with decreasing wages for men in certain occupations.
Researchers found that gut bacteria can sway food choices by releasing signaling molecules into the gut, influencing physiological and behavioral responses. The microbiome's diversity of interests can be manipulated through diet and supplement changes, offering a tractable approach to obesity and unhealthy eating.
Regular use of aspirin or other NSAIDs has been found to reduce the risk of hormone-related breast cancer recurrence by half in overweight and obese women. The study suggests that limiting inflammatory signaling may be an effective approach to altering the cancer-promoting effects of obesity.

Grizzlies become diabetic only weeks after hibernation, but then recover when they wake up in the spring. The study reveals how natural biology can teach us about animal coping mechanisms with diseases.
A recent study published in Critical Care Medicine found that heavier patients are more likely to survive sepsis, a life-threatening infection. This obesity paradox challenges conventional wisdom and may improve care for all patients with sepsis and other critical illnesses.
Severely overweight patients with hypoventilation can experience low blood oxygen levels during air travel. Experts recommend a pre-flight hypoxic challenge test for better preparedness and potential use of supplemental oxygen or non-invasive ventilation.
