The idea that it might be possible to be overweight or obese but not at increased risk of heart disease, otherwise known as the “obesity paradox”, has been challenged by a study of nearly 300,000 people published in in the European Heart Journal.
Researchers at Lund University in Sweden have discovered a new link between gut bacteria and obesity. They found that certain amino acids in our blood can be connected to both obesity and the composition of the gut microbiome.
Higher waist and hip size are more strongly associated with heart attack risk than overall obesity, especially among women, according to research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
In a BJS (British Journal of Surgery) analysis of published studies in obese patients with type 2 diabetes, researchers found that weight loss surgery helps prevent the development of microvascular complications—which affect small blood vessels—better than medical treatment. The analysis was conducted by investigators from the Surgical Department of the University of Heidelberg in cooperation with the Study Center of the German Surgical Society.
School-based healthy lifestyle interventions alone are not effective in the fight against childhood obesity, researchers at the University of Birmingham have warned.
The immune system reacts similarly to a high fat and high calorie diet as to a bacterial infection. This is shown by a recent study led by the University of Bonn. Particularly disturbing: Unhealthy food seems to make the body’s defenses more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced. These long-term changes may be involved in the development of arteriosclerosis and diabetes, diseases linked to Western diet consumption. The results will be published in the journal ‘Cell’.
