Being overweight

"Four million people died in 2015 as a result of being too tubby, struck by cancer, heart disease, diabetes and other killer conditions," reports The Sun. This is based on a global study that looked at how the proportion of people who are overweight and obese has changed over time. This was determined by recording body mass index (BMI), where a BMI of 25-29.9 means being overweight and 30 or above is being obese. Researchers then assessed the link between having an unhealthy BMI and health outcomes including cardiovascular disease, diabetes and cancer. It found that, despite public health efforts, obesity is on the rise in almost every country and in both adults and children. Prevalence has doubled in most countries over the past 30 years. Researchers also estimated that having a high BMI accounted for 4 million deaths globally, 40% of which occurred in people who were overweight but not yet obese. This demonstrates that being overweight may almost be as risky to health as being obese. The rate of increase in obesity was also greater in children, showing the need for interventions to halt and reverse this trend to avoid future disease and deaths. What is considered a healthy weight – BMI 20 to 25 – was unsurprisingly found to be the category with the lowest health risk. The best way to obtain and maintain a healthy BMI is to eat a healthy calorie-restricted diet and exercise regularly; two concepts that are at the core of the NHS Weight Loss Plan.

BMI categories

Being overweight may not be as unhealthy as it was 40 years ago," BBC News reports. New research has found a body mass index (BMI) of 27 is linked to the lowest rate of death – but someone with a BMI of 27 is currently classed as being overweight. BMI is a score calculated by dividing your weight (usually in kilograms) by the square of your height (usually in metres and centimetres). Currently, a BMI of 25 to 29.9 is classified as being overweight. Researchers looked at 120,528 people from Copenhagen, recruited from 1976 to 2013, and separately compared those recruited during the 1970s, 1990s and 2000s. They were followed up until they died, emigrated, or the study finished. The BMI linked to the lowest risk of having died from any cause was 23.7 in the 1970s group, 24.6 in the 1990s group, and had further risen to 27 in the 2003-13 group. It may be the case that the suggested upward shift in optimal BMI is the result of improvements in preventative treatments for weight-rela...

The Anatomy of Vitality

You are a biological entity. A living thing. An animal. An organism. You are a great galaxy of cells, the smallest units of life, a community of ten trillion. They all breathe together. You are ten trillion life forms, the sum of which is entirely different from the parts. Do the stars added together have a mind? Is the cosmos awake? Your community is alive with communication. Your cells talk to each other, intricately, intimately. You are filled with the whispering of microscopic lives. What language do I speak to myself? The language of nerves and glands, at least, but probably even more subtle dialects exist. We do not know the secrets of tumours yet, nor the detailed gossip of undifferentiated cells. No one on planet earth can say with the slightest certainty how consciousness arises from the ruckus of ionic currents in our skulls, or even if it does; the brain may be but an instrument, a lens through which we study ourselves. You would likely die without the quiet energies tha...

Exercise

Two sets of US guidelines have revised the public health advice on physical activity to clarify that gentle exercise is not enough to improve health, The Guardian reported. Current guidelines suggest that 30 minutes of exercise a day is enough to offer health benefits, however the newspaper said that adults “need to add jogging and twice-weekly weight-training sessions if they want to cut their risk of heart disease and obesity.” The newspaper reports that “the lightest of activities such as dusting and the stroll to the car are being counted as exercise” and quotes the researchers as saying that people have “not accepted, and others have misinterpreted the original recommendation.” The expert panel process and the recommendations offered have clarified some of the more unclear recommendations that were published in 1995. The group of experts met in 2000 to prepare this update, and this was supplemented by panel members’ own searches of the literature. It is not possible to validate ...
