After just one day of skipping breakfast, insulin levels were significantly higher and glucose levels more elevated than after eating breakfast.
A new Ohio University study reveals that male mice fed a high-fat diet and becoming obese are more likely to father offspring with similar higher levels of body fat. The study suggests epigenetic factors may be responsible for these inherited traits.
A new animal study finds that short-term use of antidepressants, combined with stress and a high-fat diet, leads to long-term increases in body weight. The study suggests that the medication, rather than the diet alone, contributes to the weight gain, which is accompanied by increased bone and spleen weights.
A new drug has been found to increase the amount of energy burned by fat tissue, leading to significant weight loss and improved metabolic health. The drug, GC-1, mimics the activity of thyroid hormone and has been shown to promote thermogenesis in white adipose tissue.

A study found that insufficient sleep raises levels of a substance in the body that controls pleasurable eating, leading to increased hunger and appetite. The research suggests that this may be due to an elevation in the endocannabinoid molecule 2-arachidonoylglycerol, which is involved in signaling rewarding events and enjoyment of food.

The study, conducted across six US cities, analyzed data from over 4,000 adults and found that healthy food options and walkability are key predictors of lower obesity rates.
A new study by Johns Hopkins researchers found that obese patients trust weight-related counseling from overweight physicians more than normal-weight physicians. Patients seeing an obese primary care physician were also more likely to perceive weight-related stigma.
Adding gastric bypass surgery to lifestyle and medical management improved metabolic risk factors in type 2 diabetes patients, particularly those who experienced significant weight loss. The study found that 43% of the gastric bypass group achieved an HbA1c level of less than 7%, compared to 32% in the lifestyle-medical management group.
A new study by the RAND Corporation found that bariatric surgery can lead to better short-term control of abnormal blood sugar levels and more weight loss in diabetic patients with moderate obesity. However, the findings come from a relatively small number of trials and more information is needed about long-term benefits and risks.
Scientists identify five epigenetic biomarkers associated with better weight loss response in obese adolescents participating in the EVASYON weight loss program. These biomarkers may help predict an individual's response to weight loss intervention and offer therapeutic targets for enhancing its effects.
