Researchers at Oregon State University have found organisms in the gut microbiome could play a key role in type 2 diabetes, opening the door to possible probiotic treatments for a serious metabolic disease. A key risk factor for type 2 diabetes is being overweight, often a result of a western diet in combination with low physical activity. The paper, ‘Transkingdom interactions between Lactobacilli and hepatic mitochondria attenuate western diet-induced diabetes’, was published in Nature Communications.
UT Southwestern scientists have discovered a type of cell responsible, at least in mice, for triggering inflammation in fat tissue. When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. The findings, ‘Perivascular mesenchymal cells control adipose-tissue macrophage accrual in obesity’, published in Nature Metabolism, could eventually lead to new ways to treat obesity.

There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals. Scientists also suspect that during infection, fat cells release substances into the bloodstream that boost the inflammatory reaction triggered by the virus in the organism.
More than half of men (55%) and two thirds (65%) of women currently aged 20 years in India will likely develop diabetes in their life time, with most of those cases (around 95%) likely to be T2DM, according to research by an international team from India, the UK and the US, led by Dr Shammi Luhar, Department of Public Health and Primary Care, University of Cambridge, UK.
Young children of African ancestry are more at risk of developing obesity if they possess a genetic variant that reduces their ability to produce the hormone leptin, according to a study, ‘Genetic Studies of Leptin Concentrations Implicate Leptin in the Regulation of Early Adiposity’, published in the journal Diabetes. Interestingly, adults with the variant do not have the same risk, suggesting that leptin plays a role in the development of obesity at a young age but the obesity does not continue into adulthood.

While all adults who are overweight or have obesity are at greater risk for serious complications from the disease, the link is strongest for those age 50 and under. More than 42 percent of American adults have obesity, according to the Centers for Disease Control and Prevention, and approximately another 30 percent are overweight.
Researchers from Brazil have developed and validated an accurate predictive model that comprises the sum of five outcome variables to predict success of Roux-en-Y gastric bypass (RYGB) based exclusively on patients’ preoperative characteristics. The findings could be used to prioritise patients with the best indication for the procedure and incorporated in the public health system as a support tool in the decision-making process.
Researchers have discovered a previously unknown way that pancreatic cells decide how much insulin to secrete, which could provide a promising new target to develop drugs for boosting insulin production in people with T2DM. In two papers published in Cell Metabolism, scientists from the University of Wisconsin-Madison and their colleagues point to an overlooked enzyme known as pyruvate kinase as the primary way pancreatic beta cells sense sugar levels and release the appropriate amount of insulin.
Preventing heart attacks and strokes in type 2 diabetes patients managed in primary care should be an urgent priority, according to the study, ‘Half of patients with type 2 diabetes mellitus are at very high cardiovascular risk according to the 2019 ESC/EASD categories: data from a large Mediterranean population’, published on World Diabetes Day in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).

Body image is a mediating factor of depression in subgroup of laparoscopic sleeve gastrectomy (LSG) patients with poor psychological outcome, report researchers from the Medical University Hospital Tübingen, Tübingen and the University of Duisburg-Essen, Essen, Germany. They noted that the current preparation and aftercare regimes for patients that undergo bariatric surgery often focus on nutrition and physical activity, but hardly target psychological components, and interventions to improve body image should be incorporated into aftercare regimes.
Researchers from Oklahoma Medical Research Foundation (OMRF), Oklahoma City, OK, have redefined how the so-called gut microbiome operates and how our bodies coexist with some of the 100 trillion bacteria that make it up. The findings, ‘Proximal colon–derived O-glycosylated mucus encapsulates and modulates the microbiota’, were published in the journal Science, and could lead to new therapies for inflammatory bowel disease and people who've had portions of their bowels removed due to conditions like colon cancer and ulcerative colitis.
A study by Princeton University and Mpala Research Center, in Kenya, has found evidence for the ‘mismatch’ hypothesis when they found that obesity, diabetes and cardiovascular illnesses increased among whose diet changed from animal-based to carbohydrate-based. The mismatch hypothesis argues that our bodies have evolved and adapted to digest the foods that our ancestors ate and that human bodies will struggle and largely fail to metabolise a radically new set of foods.
Undertaking aerobic exercise prior to bariatric surgery in addition to standard medical care decreased the length of hospital stay in patients receiving bariatric surgery, compared to standard medical care alone, according to the outcomes of a small pilot trial by researchers from University of Virginia, Charlottesville, VA.

Researchers from the University of Oregon’s Prevention Science Institute have developed a complicated model to determine the roles nature and nurture play when it comes to children and their weight. Nature – genetics - plays a larger role, but nurture is also substantially responsible for whether a child has obesity.
Researchers at the University College London and University College London Hospitals NHS Foundation Trust), London, UK, have found that the vast majority of participants with new onset loss of smell were seropositive for SARS-CoV-2 antibodies, and this acute loss of sense of smell needs to be considered globally as a criterion for self-isolation, testing and contact tracing in order to contain the spread of COVID-19. Indeed, the authors noted that the loss of a sense of smell may be a more reliable indicator of Covid-19 than cough or fever.
In a survey of physicians, certified by the American Board of Obesity Medicine (ABOM), by researchers at Johns Hopkins Medicine, has found that these practitioners commonly offer key services supported by scientific research and clinical trials. This suggests that primary care clinicians can be increasingly confident that their patients will receive this ‘evidence-based care’ when referred to an obesity specialist.
The European Association for the Study of Obesity (EASO) and the European Coalition for People Living with Obesity (ECPO) are urging patients to continue their treatment for obesity and not to let it lapse because of fears about COVID-19. The organisations are very concerned that people seeking treatment for overweight and obesity have either postponed or stopped seeking medical advice because of fears they may be putting themselves at risk.
An editorial accompanying a study published in the Journal of the American College of Cardiology is bringing attention to the underappreciated and often overlooked issue of malnutrition among people with obesity. Malnutrition is defined as faulty nutrition due to inadequate or unbalanced intake of nutrients.
Some people are at higher risk of developing obesity because they possess genetic variants that affect how the brain processes sensory information and regulates feeding and behaviour, according to findings from scientists at the University of Copenhagen. The outcomes support a growing body of evidence that obesity is a disease whose roots are in the brain.
People who are severely overweight are less likely to be able to re-wire their brains and find new neural pathways, a discovery that has significant implications for people recovering from a stroke or brain injury. In the paper, ‘Obesity is Associated with Reduced Plasticity of the Human Motor Cortex’, published in Brain Sciences, researchers from UniSA and Deakin University report0 that brain plasticity is impaired in people with obesity, making it less likely that they can learn new tasks or remember things.
Excess fat stored around the abdomen (central fatness) is associated with a higher risk of early death from any cause, regardless of overall body fat, whereas larger hips and thighs are associated with a lower risk, according to researchers from Iran and Canada. The results suggest that measuring central fatness may be a more reliable indicator of risk of death from excess weight and could be used alongside body mass index to help determine the risk of premature death.
Five to 10 percent of surgically induced weight loss is associated with improved life expectancy and cardiovascular health compared with about 20 percent weight loss is necessary to observe similar benefits with a non-surgical treatment, according to researchers from Cleveland Clinic. In comparison. The findings also show that metabolic surgery may contribute health benefits that are independent of weight loss.

A pooled analysis of large-scale registry studies by UK researchers suggests that bariatric surgery is associated with reduced long-term all-cause mortality and incidence of obesity-related diseases (new-onset diabetes, high blood pressure, high cholesterol and heart disease etc) in patients with obesity for the whole operated population. The outcomes highlight that broader (increased) access to bariatric surgery for people with obesity may reduce the long-term sequelae of this disease and provide population-level benefits.
Young adults with underlying conditions such as morbid obesity, diabetes and hypertension are at the highest risk of being placed on a ventilator or dying from COVID-19, according to a study of 3,000 hospitalized patients aged 18 to 34. It confirmed first and foremost that black and Hispanic people have been the worst affected by the pandemic: they accounted for 57 percent of all young adults who were hospitalized and 49 percent of those who died or needed ventilation, representing about a third of all young people.
The number of people with pre-diabetes who go on to develop type 2 diabetes has been reducing over the past two decades, according to a study led by University of Manchester epidemiologists. However, the changes, according to lead author, Dr Rathi Ravindrarajah, are likely to be attributed to changes in the definition of pre-diabetes and recording practices, as well as preventative work by the NHS., such as the NHS Diabetes Prevention Programme.

People with obesity who intentionally (not because of illness) lost an average (median) 13% of their initial body weight reduced their relative risk of developing type 2 diabetes by 42%-44%, sleep apnoea by 22%-27%, high blood pressure by 18%-25%, and dyslipidaemia by 20-22%, according to a study of over 550,000 adults in primary care in the UK. The study authors believe it is the first of its kind to quantify the benefits of intentional weight loss on the risk of obesity-related conditions in real-world clinical practice.
People with obesity who gain weight have a tendency to perceive their own body size as smaller than it actually is compared to those who maintain a stable weight, according to research following more than 2,000 people with obesity from the Swedish Obese Subjects (SOS) study over ten years.
A detailed analysis of UK data from a global obesity study (the ACTION-IO study) has shown that, on average, people with obesity (PwO) in the UK were struggling with their weight for nine years before they sought help from a healthcare professional/HCP, much longer than the global average of six years. This delay puts PwO at additional risk of developing obesity-related conditions such as type 2 diabetes (T2D), obstructive sleep apnoea (OSA) and cancer. Additionally, more than half of the PwO had never discussed their weight with an HCP.
The latest findings from the annual Scandinavian Obesity Surgery Registry (SOReg) report could challenge existing recommendations and clinical practice for bariatric surgery and type 2 diabetes (T2DM) patients, according to the authors of a summary paper of the report, ‘Bariatric Surgery: There Is a Room for Improvement to Reduce Mortality in Patients with Type 2 Diabetes’, published in Obesity Surgery.

Individuals whose overweight or obesity is diagnosed in hospital are 60% more likely to die compared to the general population, according to a nationwide Danish study that followed over 1.9 million people for up to 40 years, presented at The European and International Congress on Obesity. The risk of dying was highest within the first year of diagnosis but remained markedly higher for individuals with hospital-diagnosed overweight or obesity over the whole study period.
Data presented in a special COVID-19 session at the European and International Congress on Obesity (ECOICO 2020) suggests that there are overlaps between the immunological disturbances found in both COVID-19 disease and patients with obesity, which could explain the increased disease severity and mortality risk faced by patients with obesity and COVID-19. Since fat mass generally increases with ageing, this might also partly explain the increased death risk in older patients.
An online survey of nearly 3,000 UK adults suggests that people would prefer health professionals to use the words "weight", "unhealthy weight", and "overweight" when discussing weight status, and reveals parents' desire to avoid their children being referred to as "fat", "extra-large", or "plus size".
More than half of adults have found it difficult to manage their weight during the COVID-19 lockdown, according to the results of an online survey involving over 800 UK adults, presented at The European and International Congress on Obesity. Most of the respondents said their difficulties stemmed from increased snacking, not exercising as much as usual, increased anxiety or stress and not being able get hold of healthier food.
