Insulin News and Research

RSS

Insulin is a hormone that is needed to convert glucose, starches and other food into energy needed for daily life. Insulin allows cells to use glucose for fuel and is secreted by beta cells in the islets of Langerhans. The release of insulin from the pancreas is stimulated by increased blood glucose, vagal nerve stimulation, and other factors. Insulin is obtained from various animals and available in a variety of preparations. Commercial insulin preparations differ in a number of ways, including differences in the animal species from which they are obtained; their purity, concentration, and solubility; and the time of onset and duration of their biologic action. An oral hypoglycemic agent is not a form of insulin therapy.

Certain diabetes patients face higher ketoacidosis risk with SGLT2 drugs

Patients with type 2 diabetes who have high blood glucose levels, low body weight, or a history of ketoacidosis are at increased risk of developing this serious condition when treated with so-called SGLT2 inhibitors.

GLP-1 drugs have benefits beyond weight loss. Could microdoses preserve them?

A narrative review suggests GLP-1-based therapies deliver metabolic, cardiovascular, renal, and other systemic benefits, raising interest in whether lower fractional doses could improve tolerability and treatment continuity. However, direct evidence for GLP-1 microdosing remains extremely limited, and researchers say prospective studies are needed to determine whether lower doses preserve long-term benefits.

The scale told a similar story across three diets. The liver told a different one

In a randomized controlled trial of people with metabolically unhealthy obesity, approximately 10% weight loss improved insulin sensitivity and several cardiometabolic measures across ketogenic, Mediterranean, and very-low-fat plant-forward diets. However, the very-low-carbohydrate ketogenic diet produced larger improvements in hepatic insulin sensitivity and greater reductions in liver fat and several glucose and insulin measures than the higher-carbohydrate diets.

Is there a best day to take GLP-1 drugs? Researchers looked for an answer

A systematic review of 1,000 screened records identified only three eligible studies examining administration timing for semaglutide, and none directly compared different days of the week or assessed tirzepatide timing. The limited evidence suggests flexible dosing may support adherence and tolerability without compromising glycemic control or weight loss, but these findings rely largely on indirect evidence and expert opinion rather than direct comparative trials.

Met-HeFT trial finds no cardiovascular benefit from metformin

Metformin did not significantly affect the risk of cardiovascular outcomes in patients with heart failure with reduced ejection fraction and diabetes or at risk of diabetes.

People with diabetes may have another reason to protect their cardiovascular health

Better cardiovascular health, measured using Life’s Essential 8, was associated with a lower risk of mild cognitive impairment among people with diabetes after accounting for genetic susceptibility. Associations with dementia varied by genetic risk, while higher LE8 scores were also linked to greater gray matter volume and lower white matter hyperintensity volume.

Type 1 diabetes cases projected to increase worldwide by 2049

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) estimates the number of people living with type 1 diabetes (T1D) worldwide will increase by 29% from 9.4 million in 2025 to 12.1 million in 2049.

Study identifies role for peroxisomes in protecting insulin and maintaining beta cell health

Researchers at LSU's Pennington Biomedical Research Center have identified a previously underappreciated role for tiny structures inside cells called peroxisomes in protecting insulin and maintaining the health and maturity of insulin-producing pancreatic beta cells.

Sunlight, blood sugar and diabetes: a new study finds an intriguing connection

Higher short-term ambient UVA exposure was associated with modestly lower blood glucose levels, particularly during winter, in a large UK Biobank analysis. Separately, more frequent solarium use, used as a proxy for habitual sunlight exposure, was associated with a lower hazard of type 2 diabetes, although the observational findings do not establish causality.

Ketogenic diet excels at reversing prediabetes and fatty liver

There is no shortage of popular diets to try, and they can generally produce weight loss if followed to the letter. But are all diet plans created equal in terms of reducing the cardiometabolic risks that come with obesity, such as Type 2 diabetes and liver disease?

Ketogenic diet provides greatest health benefits for treating obesity

A diet that severely limits carbohydrates but is high in fat has the greatest health benefits for people with obesity compared to a Mediterranean diet or a low-fat diet, according to a clinical trial publishing August 27 in the Cell Press journal Cell Metabolism.

Metformin cuts preterm birth risk among high-risk mothers

A common diabetes medication can reduce the risk of early and preterm births for mothers at high metabolic risk, according to new research led by Monash University.

Maternal obesity alters fetal liver metabolism via placental molecular signals

A mother's obesity during pregnancy may send molecular signals across the placenta that permanently alter her son's liver metabolism, according to a new study in mice published in Nature Communications.

A year after women lost weight, researchers saw which health gains lasted and which faded

Diet-induced weight loss significantly reduced predicted 10-year risks of major adverse cardiovascular events and type 2 diabetes in healthy premenopausal women with overweight, regardless of whether aerobic or resistance exercise was added. Some of these gains diminished as weight was partially regained over the following year, although greater exercise adherence was associated with less rebound in predicted diabetes risk.

Diabetes study reveals differing health risks for men and women

In the years following type 2 diabetes diagnosis, women are more likely to develop mental health conditions, while men are more likely to develop cardiovascular and renal complications, according to a study published August 25th in the open access journal PLOS Medicine by Fabiola Eto from Queen Mary University of London, UK, and colleagues.

What decades of wine research can, and cannot, tell us about health

A narrative review found that moderate wine intake has repeatedly been associated with lower all-cause and cardiovascular mortality, with proposed mechanisms involving ethanol and grape-derived polyphenols, but the evidence remains largely observational and cannot establish causation. The authors argue that drinking pattern, beverage type, age, cancer risk, and risk-modeling choices all influence how the J-shaped association should be interpreted and how alcohol guidelines are developed.

From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).
