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. The outcomes were featured in the paper, ‘Pre-operative aerobic exercise on metabolic health and surgical outcomes in patients receiving bariatric surgery: A pilot trial’, published in PLOS One.
Access to bariatric surgery should be increased as part of the main treatment considerations in women with obesity and polycystic ovarian syndrome (PCOS). The paper, ‘A Review of the Impact of Bariatric Surgery in Women With Polycystic Ovary Syndrome’, published in Cureus, led by California Institute of Behavioral Neurosciences & Psychology, Fairfield in the US, also recommends that additional research with better study designs are required in the future to investigate the relationship between PCOS and bariatric surgery.

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.

There is a clear relationship between obesity and the severity of COVID-19 disease, according to research presented by François Pattou, Professor of Surgery at the Faculty of Medicine of the University of Lille, and head of the Department of General and Endocrine Surgery at Lille University Hospital, France, at this year's European and International Congress on Obesity.
A study of obesity among the largest Latino populations living in New York City (NYC) has reported that the prevalence of obesity varies widely with Mexicans and Puerto Ricans much more likely to have obesity than Dominicans, Ecuadorians and Colombians.
Biomedical engineers at Duke University have shown that the efficacy of a two-pronged type 2 diabetes treatment increases when the drugs are linked by a heat-sensitive tether rather than simply concurrently administered. The combination molecule is formed by an elastin-like polypeptide (ELP) linker that forms a gel-like depot when injected under the skin, which slowly dissolves and releases the active drug over time.
Expectant mothers with obesity may hinder the development of the babies' brains as early as the second trimester, according to a new study led by researchers at NYU Grossman School of Medicine. The study linked high body mass index (BMI) to changes in two brain areas, the prefrontal cortex and anterior insula. These regions play a key role in decision-making and behaviour, with disruptions having previously been linked to attention-deficit/hyperactivity disorder (ADHD), autism and overeating.
As a person's weight increases all regions of the brain go down in activity and blood flow, according to a brain imaging study, ‘Patterns of Regional Cerebral Blood Flow as a Function of Obesity in Adults’, published in the Journal of Alzheimer's Disease.
Twenty-nine leading international partners have joined forces to establish a research consortium Stratification of Obese Phenotypes to Optimize Future Obesity Therapy (SOPHIA) with the aim of improving risk assessment of comorbidities and treatment for people with obesity. Obesity complications are common, but predicting who will develop any of the 200 known complications of obesity is extremely difficult. Moreover, there are insufficient predictors for who will respond to obesity treatments.
The childhood obesity rate may increase 2.4% or 1.27 million children if school closures to prevent the spread of the coronavirus continue into December, according to the study, ‘Projecting the impact of COVID-19 pandemic on childhood obesity in the U.S.: A microsimulation model’, published in the Journal of Sport and Health Science.
Researchers from the Open University of Catalonia and the Universitat Pompeu Fabra Department of Communication, Barcelona, Spain respectively, have performed a study based on the assumption that advertising is one of the factors that contributes to the obesogenic environment.
