Stopping weight loss drugs leads to rapid weight regain and health reversal

Stopping weight loss drugs is followed by weight regain and reversal of beneficial effects on heart and metabolic health markers such as high cholesterol and high blood pressure, finds a study published by The BMJ today.

BATF2: A novel tumor suppressor silenced by glutamine in head and neck cancer

A novel tumor suppressor, BATF2, can be silenced by factors in the tumor microenvironment, leading to a reduced immune response in five preclinical models of head and neck cancer, according to researchers from The University of Texas MD Anderson Cancer Center.

Higher intake of food preservatives linked to increased risk of type 2 diabetes

Higher consumption of food preservatives, widely used in industrially processed foods and beverages to extend their shelf life, has been linked to an increased risk of type 2 diabetes.

Can ketogenic diets help PCOS? New analysis points to weight and insulin gains

A systematic review and meta-analysis of 15 studies found that ketogenic diets were associated with short-term reductions in body weight, waist circumference, insulin resistance, and some reproductive hormones in women with polycystic ovary syndrome, primarily among those with overweight or obesity. However, substantial heterogeneity, low certainty of evidence, limited safety reporting, and short follow-up periods mean the clinical effectiveness and long-term sustainability of ketogenic diets in PCOS remain uncertain.

"Blue zones" longevity claims validated by new research

A new peer-reviewed paper published in The Gerontologist provides the most comprehensive scientific response to date addressing recent critiques of the so-called "blue zones," regions of the world known for unusually high concentrations of people living long, healthy lives.

Depression links to chronic headaches through weight and diet, not physical activity alone

Depression was associated with a higher likelihood of chronic headaches in Iranian adults, with statistical models identifying body mass index and dietary iron intake as partial mediators. Physical activity was linked to depression but did not independently mediate headache outcomes, highlighting interconnected, non-causal pathways.

Prediabetes prevalence doubles over two decades in Finnish children with obesity

The prevalence of prediabetes has increased significantly in recent years among Finnish children living with overweight or obesity, a recent study by Tampere University and the University of Eastern Finland shows.

Paternal microplastic exposure alters metabolic health in offspring

A study led by biomedical scientists at the University of California, Riverside, has shown for the first time that a father's exposure to microplastics (MPs) can trigger metabolic dysfunctions in his offspring.

High-fat cheese and cream consumption links to lower dementia risk over 25 years

Higher intake of high-fat cheese and cream was associated with a lower risk of all-cause dementia over 25 years in a large Swedish cohort, while low-fat dairy showed no association. Associations were strongest for vascular dementia and among APOE ε4 non-carriers, with findings remaining observational.

Fatty diets reprogram hepatocytes and increase liver cancer risk

One of the biggest risk factors for developing liver cancer is a high-fat diet. A new study from MIT reveals how a fatty diet rewires liver cells and makes them more prone to becoming cancerous.

Genes influence the gut microbiome beyond the individual

The gut microbiome - made up of trillions of microbes in the digestive tract - is vital for digestion and overall health. Diet and medication shape these microbial ecosystems, but the contribution of genetics has been more difficult to ascertain.

Nanoplastics alter the gut barrier and metabolism depending on diet

A team of researchers from INRAE, CNRS, and the University of Lille studied how low dietary doses of nanoplastics affected mice.

Cutting carbs, not fat, may better control appetite in women

Research indicates low-carb diets may enhance appetite regulation and reduce food cues in women with lipedema, offering a dietary intervention advantage.

Estrogen drives gut pain and explains higher rates of IBS in women

Women are dramatically more likely than men to suffer from irritable bowel syndrome (IBS), a chronic condition causing abdominal pain, bloating, and digestive discomfort.

Ultra-processed foods linked to higher mortality in Black women with breast cancer

A study from Rutgers Cancer Institute researchers in eClinicalMedicine is the first to link ultra-processed foods to reduced survival in Black women with breast cancer.

Orthorexia nervosa links strongly to perfectionism and OCD traits, review shows

This umbrella review synthesised five meta-analyses to estimate the reported prevalence of orthorexia nervosa and examine its psychological correlates. Findings show wide variability in prevalence estimates and consistent links with eating disorder symptoms, obsessive-compulsive traits, and perfectionistic strivings, limited by high methodological heterogeneity.

Gestational diabetes alters the placenta at the molecular level, study reveals

Gestational diabetes can cause a multitude of complications in the offspring, but to date, the reasons are incompletely understood.

Scientists unravel how citrin deficiency can trigger fat buildup in the liver even in lean individuals

Scientists at City of Hope, one of the largest and most advanced cancer research and treatment organizations in the U.S. and a leading research center for diabetes and other life-threatening illnesses, have unraveled how citrin deficiency (CD), a rare genetic disorder that prevents the liver from converting food into energy efficiently, can trigger fat buildup in the liver - even in lean individuals.

Folate deficiency drives genetic changes linked to lung cancer

Genetic alterations lie at the heart of cancer development, but scientists may have been overlooking a powerful driver of these changes—the everyday nutrients that feed our cells.

Social living allows genetic effects to spread through the gut microbiome

Your "roommate's" genes could be influencing the bacteria living in your gut, and vice versa, according to a study of rats published today in Nature Communications.
