BMI: Tom Brady is obese?
Your Body Mass Index (BMI) is a measurement of your body fat percentage. And based on the results, you are labeled normal, overweight or obese. But BMI can give you some crazy results. Using this measurement, I’m considered obese. And so is NFL superstar Tom Brady. You see, BMI only compares your height against your weight. It doesn’t distinguish between fat and muscle. But here’s the thing… Muscle is much denser than fat. So if you have a lot of muscle, you can have a high BMI but still be lean. There’s a much more reliable test to measure your body’s composition of fat and muscle. It’s called dual-energy X-ray absorptiometry (DXA or DEXA). In my clinic, it’s one of the first tests I give to my patients. You probably know the DEXA test as the gold standard for measuring bone density. But new research shows it can also give you a detailed snapshot of your body’s composition of bone, muscle and fat. In a recent study of 50 women, doctors compared BMI with DEXA results. They found that some women who were told they were overweight based on their BMI actually had normal fat levels on their DEXA.1 And 18.5% of the women with normal BMI actually had a lot of excess fat based on their DEXA. In other words, they were “skinny fat” people. You see, the BMI also can’t measure deadly visceral fat. This type of fat collects in your abdominal cavity. It surrounds your organs and restricts them. Vis...
In this study, we examine how the frequency of SNS use is associated with active travel (i.e., walking and cycling) and body mass index (BMI) in the Glasgow and Clyde Valley Planning area, Scotland. We employ both a self-reported measure of active travel from a travel diary (N = 1684) and an objective measure of average walking hours from Global Positioning System (GPS) data (N = 282) collected in 2015. These are analysed with statistical models (i.e., binomial logistic regression, multinomial logistic regression and linear regression models). We find that there is no significant association between the frequency o...
ConclusionsThe present results suggest that individuals with diabetes have higher prevalence of hearing impairment. There is the need of longitudinal studies to investigate if diabetes is a risk factor to hearing impairment.
New drugs that lower levels of triglycerides (a type of fat) in blood could further reduce the risk of heart attack when added to statins, according to new research conducted by MRC scientists.
ConclusionWe reported an excellent validity and reliability of subjective visual comparison of ante- and post-mortem CT-data using an anatomical based classification of the sphenoid sinus.

MedAutonomic has made significant progress with its brain neuromodulation technology. The Silicon Valley and Venice, Italy-based company said it had successfully implanted the Phoenix device into the stomach wall of a human through a digestive endoscopic procedure. The device sends signals to the brain (the limbic system)to reset an imbalance in the Autonomic Nervous System with the aim to treat functional diseases such as type-2 diabetes, hypertension, and gastroesophageal reflux disease (GERD). The company said Phoenix is able to harvest energy from the body, so it can remain in the stomach wall without the need of a bat...
Analysis of NHANES data showed no overall benefit of statins for primary prevention, with the exception of adults with type 2 diabetes, and only for those aged 75 to 84 years.Medscape Medical News
Carrageenan is a controversial food additive. It is FDA-approved, but some scientists believe that it can cause inflammation, bowel disorders, and even certain cancers. In this article, we look at the research behind carrageenan, including its possible side effects, dangers, uses, and common foods that contain it.
