A significant reduction in the risk of developing diabetes was observed in individuals who underwent bariatric surgery compared to those receiving traditional care. The Swedish Obese Subjects study found that bariatric surgery can reduce the risk of diabetes by over 80% among obese patients.
A study by University of Iowa researchers found that morbidly obese patients experience higher dislocation rates due to increased thigh girth, which creates hip instability. The team suggests surgeons modify procedures and consider new implant designs to minimize this risk.
A lack of AgRP-neurons leads to obesity if fed a regular carbohydrate diet, but high-fat diets counteract this effect. The study reveals the importance of brain-cell interactions in nutrient metabolism and storage.
A recent study published in CMAJ found that total sleep time and quality significantly predict fat loss in individuals enrolled in a weight loss program. Incorporating adequate sleep into lifestyle packages is now recognized as crucial for effective obesity management.
Researchers discovered that a protein called SIRT1 rewrites the histone code in developing fetuses, affecting their likelihood of being overweight or obese. Modifying fat intake during pregnancy to a moderate level can benefit children, regardless of mother's size.
A study comparing bariatric surgical procedures found that the duodenal switch (DS) achieves better weight loss and controls co-existing illnesses in patients with a BMI over 50. The DS was also associated with lower weight loss failure rates and improved comorbidity control compared to gastric bypass.

Scientists discovered that invariant natural killer T-cells (iNKT) in fat tissue regulate inflammation and protect against obesity, diabetes, and metabolic syndrome. iNKT cells can be restored through weight loss and activated by alpha-galactosylceramide, a lipid known to improve metabolism.
A new study reveals that gut microbes can increase the absorption of dietary fats, allowing the body to extract more calories from the same amount of food. Firmicutes bacteria are found to play a key role in this process, and their abundance is influenced by diet.
Researchers found that a timed high-fat diet reduces body weight and alters metabolism to utilize ingested fats for energy between meals. The study suggests scheduling food consumption can be a therapeutic tool to prevent obesity in humans.
A recent study published in Diabetes Care found that Latinos are more vulnerable to fatty pancreas and Type 2 diabetes due to their ability to store excess fat in the pancreas. This can lead to a reduced capacity for insulin production, increasing the risk of developing the disease.
The Endocrine Society recommends screening adults for hypertriglyceridemia every five years to identify individuals at risk of cardiovascular disease. Treatment focuses on lifestyle changes and addressing secondary causes, such as obesity and endocrine conditions.
