The research reveals high rates of obesity and diabetes among these groups, with disparities exceeding those experienced by non-Hispanic white adults.
A recent study published in the journal Appetite found that marketing food as a 'meal' rather than a 'snack' can lead to reduced consumption and overeating. Researchers discovered that participants who consumed pasta labelled as a 'snack' ate more at a subsequent taste test compared to those who had eaten it as a 'meal'. This suggests ...
A study characterises the clinical, physical, physiological and dietary patterns of the overweight/obese population with primary hypertension. The researchers found that a profile of high cardiovascular risk includes hypertension diagnosis, excess weight/obesity, poor cardiovascular fitness, and unhealthy dietary habits.
Researchers aim to understand why eating late disrupts natural circadian rhythms and affects weight, glucose, and hormone levels. They will conduct a randomized, long-term study on adults with obesity to compare weight and metabolic effects of daytime versus delayed eating schedules.
A high waist-to-hip ratio is associated with a significantly higher rate of complications, longer hospital stays, mortality, and 30-day readmissions after emergency general surgery procedures. The study suggests that measuring waist-to-hip ratio via CT scan may be a reliable predictor of adverse outcomes.

Researchers found that genetic predisposition increases risk of high triglycerides, but maintaining a healthy body weight or changing diet can help reverse the risk. A specific gene mutation was associated with higher circulating triglycerides, but the correlation was dependent on BMI and dietary intake.
Researchers found that semaglutide reduced hunger and cravings for food, leading to an average weight loss of 5kg (11lbs) from body fat. The study suggests the drug's potency is due to its action on appetite control receptors in the brain.

The study suggests that financial measures...
A study published in Science Advances found that mice born by C-section gained an average of 33% more weight than those born vaginally over the course of 15 weeks after weaning. The researchers also discovered significant differences in bacterial species in their guts, with mice born by C-section having a less mature microbiome structure.
A study published in Nature Communications identifies MKK6 as a key protein controlling white-to-brown fat conversion. This process enables lipids to be burned for heat instead of stored, potentially reducing obesity. Mice lacking MKK6 exhibit reduced body weight and protection against obesity.

They discovered that lipolysis, which breaks down stored fat, is not essential for heat production in response to cold exposure, but rather regulates fuel selection and white fat browning.
A 28-study analysis reveals night shift workers are more likely to develop abdominal obesity and experience an increased risk of obesity compared to permanent day workers. Modifying working schedules to avoid prolonged exposure to long-term night shifts might help reduce this risk, according to the study.
A fecal transplant from a lean donor can temporarily improve insulin resistance in obese men, but only half of the recipients responded. The success of the treatment depends on each patient's fecal gut-bacterial makeup, which can be predicted through analysis.

Scientists at the University of Warwick have identified tanycytes, key brain cells controlling appetite, which detect amino acids in food and inform the brain about fullness. Eating foods high in specific amino acids can activate these cells, leading to feelings of fullness and potentially aiding weight management.
Researchers found that a diet rich in saturated fats damages the brain's hunger control system within days, while gut bacteria changes occur weeks later. The study suggests that this sequence of events may contribute to weight gain and obesity.
A new study suggests that weight loss in adults leads to significant cost savings, peaking at age 50.

The research found that participants with a specific combination of Prevotella and Bacteroides bacteria lost more weight and body fat when following a high-fiber diet.
A new non-surgical device has shown promising results as an NHS treatment for people with type 2 diabetes and obesity. After one year, participants lost significant weight, had improved blood sugar control and reduced systolic blood pressure, with high patient satisfaction levels.
A new study published in Diabetologia found that cognitive behavioral group therapy (CBGT) is no better than standard care at preventing weight regain after dieting in people with type 2 diabetes. CBGT aimed to change thought patterns and behaviors, but failed to improve cardiovascular risk factors or psychological wellbeing.
Studies suggest having an obese spouse substantially increases a man's risk of developing type 2 diabetes, while women with an obese partner are not at increased risk. The research highlights the importance of screening spouses for diabetes if obesity is found in one person.
A large study found that metabolically healthy obese individuals have a higher risk of coronary heart disease, cerebrovascular disease, and heart failure compared to normal weight individuals with no metabolic abnormalities. Underweight individuals also face increased risks for certain cardiovascular diseases.
A new method of analyzing subcutaneous fat has been developed to predict which patients will respond well to obesity surgery. The FAT score technique showed a significant association between a patient's fat score and their response to surgery, with severely obese patients having an increased risk of poor weight loss response.
A large study found that individuals with 'metabolically healthy obese' (MHO) have a higher risk of cardiovascular disease events, including coronary heart disease and strokes. This contradicts the notion that MHO is harmless and highlights the importance of weight loss for all obese individuals.
A new study from Uppsala University finds that genetic effects on obesity are not fixed but interact with lifestyle factors. The study reveals that physical activity and socio-economic status can reduce the impact of genes on weight.
Research suggests that mangos and their components have anti-inflammatory and anti-oxidative properties, which may help reduce risk for chronic disease. Mangos are also associated with better nutrient intake, glycemic control, and improved gut health.
A community-based study of 5248 older adults found that a healthy lifestyle can compress the disabled period by improving walking distances and diet quality. Obesity was associated with an expanded disabled period, while smoking shortened life and able life.
Researchers discovered that a particular receptor in kidney cells plays a crucial role in obesity-induced kidney damage. Targeting this receptor or its associated signaling pathway may help protect the kidneys of individuals with obesity from structural and functional changes, thereby reducing the risk of chronic kidney disease.
Researchers at LSU Health New Orleans have discovered the potential of a protein called Nischarin to treat or prevent metabolic diseases such as obesity and diabetes. The findings showed that Nischarin interacts with and controls the activity of a gene called AMPK, leading to improved glucose and insulin tolerance.
A recent CARBS study showed that salacia extract reduces appetite and manages blood sugar levels by improving glycemic indices and gut hormones in healthy overweight/obese individuals. The proprietary extract, OmniLean, also reduces spikes in blood sugar and hunger pangs.
A new study suggests that metabolically healthy obese adults consuming a diet high in unsaturated fats may be able to decrease their total cholesterol by 10 points. However, replacing saturated fats with unsaturated fats does not aid in weight loss.
Researchers found that obese people have fewer enteroendocrine cells in the gut, reducing satiety hormones and altering appetite. Surgical weight-loss procedures can repair this disorder by restoring cell numbers and normalizing hormone release.
A study of 183 participants found that those who lost a consistent number of pounds each week had better weight loss outcomes than those with high weight variability. This suggests that developing stable behaviors related to food intake and weight loss is crucial for maintaining changes in the long term.
Underweight patients undergoing cardiac catheterisation are more likely to die, experience longer hospital stays, and incur higher costs compared to normal weight or obese patients. Morbidly obese patients, on the other hand, have better outcomes despite having a lower BMI.
