High-fat, low-carbohydrate diet may improve beta-cell function in patients with type 2 diabetes

People with type 2 diabetes on a high-fat, low-carbohydrate diet may have a better chance of reversing their diabetes than those on a low-fat diet, according to a small study published in the Journal of the Endocrine Society.

NHS grant funds study on the use of weight-loss drugs for treating PCOS

Dr. Shagaf Bakour, a gynecologist and director of medical education at Aston Medical School, has won an NHS research grant to investigate the use of weight-loss drugs in the treatment of polycystic ovary syndrome (PCOS).

Rising colorectal cancer rates in young Swiss adults spark concern

While the incidence of colorectal cancer is decreasing among those over 50, it is rising at an alarming rate among younger individuals, sometimes as early as their thirties.

Eating oranges daily may shift lipid patterns in fatty liver disease

A 4-week trial on 'Navelina' oranges shows potential effects on lipid metabolism in fatty liver disease, revealing intriguing but non-significant patterns.

Visceral fat strongly linked to urinary incontinence in women

The accumulation of fat in the abdominal region, especially visceral fat (fat that accumulates between organs), significantly increases the risk of stress urinary incontinence in women.

Women using GLP-1 drugs face higher weight loss stigma

In a new study exploring stigma associated with the use of GLP-1 drugs for weight loss, women who lost weight using GLP-1 medications were judged more harshly than those who lost weight through diet and exercise, with negative reactions driven largely by beliefs that medication-assisted weight loss is a "shortcut."

Ultra-processed diets may harm muscle health

Ultra-processed food diets may impair muscle health, with MRI findings showing increased fat infiltration in individuals at risk for knee osteoarthritis.

Researchers debunk the existence of the childhood "adiposity rebound" phenomenon

In new research to be presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) and published in The Journal of Nutrition, a 42-year old theory as to why children's body mass index (BMI) decreases post-infancy before then rising continuously from age six years –'the adiposity rebound' is refuted using new analyses – rather than decreasing body fat, the real reason is proposed as increasing muscle mass.

BMI increases in early childhood may reflect muscle growth, not fat

A new study published in The Journal of Nutrition, a peer-reviewed journal of the American Society for Nutrition, offers new insights into a decades-old puzzle in childhood obesity. The study found that while body mass index (BMI) starts to rise in early childhood during a stage known as adiposity rebound, when BMI increases after an initial decline, the waist-to-height ratio, a measure that better reflects body fat, continues to drop. This suggests that the BMI increase at this age mainly reflects growth in lean tissues such as muscle and bone, rather than extra body fat.

Study links ultra-processed food intake to poorer thigh muscle quality

A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.

Lower-protein toddler formula does not reduce BMI at age 2, trial finds

A large randomized trial in Germany and Spain found that lowering milk protein intake during the second year of life did not reduce BMI z-score at 24 months, though it did produce a temporary BMI reduction at 18 months. Lower protein intake also led to more stable weight and length trajectories, while higher protein intake pushed growth upward relative to WHO standards.

Ultra-processed foods linked to higher obesity risk in adolescents

Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by Mekuriaw Nibret Aweke of the University of Gondar, Ethiopia, and colleagues.

Gut-liver changes drive foodborne infection severity in fatty liver disease

A research team led by the University of California, Irvine's Joe C. Wen School of Population & Public Health has uncovered a critical biological link explaining why individuals with metabolic dysfunction–associated steatotic liver disease (MASLD), or fatty liver disease, face significantly worse outcomes from certain foodborne infections.

Matching exercise timing to body clock chronotype improves heart health

Timing exercise to match body clock chronotype-the natural predisposition to morning or evening alertness-may lower cardiovascular disease risk among those who are already vulnerable, suggests research published in the open access journal Open Heart.

Semaglutide improves liver function independently of weight loss

Researchers at Toronto's Sinai Health have found that semaglutide – the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1 – acts directly on a subset of liver cells to improve organ function and does so independently of weight loss.
