AI trained on sleep data predicts future disease and mortality years in advance

The SleepFM model reveals how sleep analysis can predict disease risk, offering insights into sleep's role as a vital health indicator for early intervention.

Weight loss drugs may cause nutritional deficiencies without proper guidance

People prescribed the new generation of weight loss drugs may not receive sufficient nutritional guidance to support safe and sustainable weight loss, leaving them vulnerable to nutritional deficiencies and muscle loss, say experts at UCL and the University of Cambridge.

Cardiovascular risk scores predict future development of serious eye diseases

A new study from UCLA Health shows that a cardiovascular risk score already used routinely in primary care can predict who will develop serious eye diseases years later.

The gut is not just digestive and new evidence shows it actively controls brain function

This comprehensive review synthesizes a decade of human and animal research to explain how the gut and brain communicate through hormonal, neural, immune, and microbial pathways. It highlights how disruptions in these pathways contribute to gastrointestinal, metabolic, and neurological disorders, and how modern therapies are beginning to exploit gut–brain signaling for clinical benefit.

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.

Muscle loss may persist after weight recovery in anorexia nervosa

Anorexia nervosa is a psychiatric condition characterized by a fear of weight gain and reduced calorie consumption that can result in dangerous weight loss.

Maintaining a healthy weight may help avoid low back pain

Low back pain (LBP) is a prevalent condition associated with disability, work loss and economic burden to healthcare. Significant risk factors include poor sleep, physical and psychological stress, inactivity, advanced age and smoking.

Increase in food prices can lead to stunted growth in children

When food prices skyrocket during an economic crisis, it is primarily urban populations and people with low levels of education who are affected.

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.

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.

How GLP‑1 agonists are shaping the future of obesity treatment with Dr Bryony Henderson

GLP-1 agonists are pivotal in obesity care, promoting weight loss and addressing related health issues, with a focus on personalized, holistic treatment.

Blood metabolite profiling outperforms BMI in predicting pregnancy complications

This study shows that a blood-based metabolomic signature linked to maternal BMI predicts gestational diabetes and preeclampsia more strongly than BMI alone, particularly in late pregnancy. A subset of 16 metabolites statistically mediates the BMI–gestational diabetes association, highlighting metabolic pathways that may improve prenatal risk stratification.

Couples-based programs boost heart-healthy behaviors

Research highlights the need for couple-based interventions in heart disease to focus on emotional support and relationship quality for better health outcomes.

Strong heart health lowers long-term death risk in cancer survivors

Higher Life’s Simple 7 cardiovascular health scores were associated with lower long-term all-cause and cancer mortality in cancer survivors from a large Italian cohort. Inflammation, resting heart rate, and vitamin D statistically explained a substantial share of these associations, supporting shared cardiometabolic pathways across cancer and cardiovascular disease.

Study examines fairness of oxygen desaturation thresholds in sleep apnea diagnosis

Obstructive sleep apnea (OSA) is a common sleep disorder in the U.S. affecting tens of millions, with estimates ranging from 25 to more than 80 million adults.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Plant-based omega-3s work better than expected in a year-long diet study

A year-long, diet-controlled intervention shows that flaxseed oil–derived alpha-linolenic acid significantly increases erythrocyte EPA, DPA, and DHA across omnivorous, vegetarian, and vegan diets. The magnitude of improvement is driven mainly by baseline omega-3 status, while absolute EPA and DHA levels in vegans remain lower than in omnivores.

Sitting harms blood vessel function, but cocoa flavanols can stop it

This study shows that cocoa flavanols can preserve endothelial function during sitting, suggesting dietary strategies to mitigate cardiovascular risks.
