We Desperately Need Scalable Treatments For Obesity

Obesity, defined as the presence of abnormal or excess body fat that impairs health, currently affects 100s of millions of people worldwide. Although “weight-loss” is a booming global multi-billion dollar business, we desperately lack effective long-term treatments for this chronic disease – the vast majority of people who fall prey to the natural supplement, diet, and fitness in… Read More »

Does Gastric Bypass Surgery Change Body Weight Set Point?

The Holy Grail of obesity treatment is to find a way to revere the resetting of the body weight set point from the highest achieved body weight to something that is lower. Unfortunately, all current treatments fail to “cure” obesity, as they fail to reset the set point to what would be considered “normal weight”. This makes ongoing treatment (be it behavioural, medical, or … Read More »

Will WHO STOPS Childhood Obesity Promote Weight Bias And Unhealthy Body Image?

Childhood obesity is a grave concern and so far community based interventions to prevent it have been rare and far between, with little evidence that any changes (however meagre) are in fact sustainable over time and will actually lead to a reduction in adult obesity. Thus, the Australian team of Steven Allander and colleagues must be commended on embarking on what I believe will be the first clus… Read More »

Does CPAP Treatment Affect Body Weight?

This prompted a reader to send me a link to a study by Luciano Drager and colleagues, published in Thorax, that presents a meta-analysis of randomised controlled trials on the effect of CPAP treatment on body weight. The authors found 2… Read More »

Is Obstructive Sleep Apnea A Barrier to Weight Loss?

Obstructive sleep apnea is a common issue in individuals with excess weight. Given that untreated sleep apnea negatively affects restorative sleep, which in turn affects both metabolism and appetite, it may well be that sleep apnea is an important barrier to weight loss. This is exactly what is suggested in a recent study by Whited and colleagues, published in Health Psychology. The researchers co… Read More »

Are There Biomarkers For Physical Fitness?

Physical fitness is perhaps the most powerful negative predictor of cardiovascular health risk (a rather complicated way of saying “fitness” is good for you). However, there is no easy way to measure fitness short of standardized exercise testing, both cumbersome and unpractical in a clinical setting. Now, a paper by Joshua Denham and Priscilla Prestes, published in Frontiers in Geneti… Read More »

Can Treating Sleep Apnea Reduce Energy Intake?

Obstructive sleep apnea is a common and significant complication of obesity and individuals with untreated sleep apnea are at considerable risk for progressive weight gain. Now, a paper by Ari Schechter and colleagues from Columbia University, NY, published in Physiology and Behaviour, publish data from a small ‘pilot study’ suggesting that treating obesity with CPAP may reduce calorie… Read More »

New IFSO Recommendations For Obesity Surgery

Surgery is no doubt the most effective treatment for severe obesity (defined here as the presence of excess body fat that impairs health). Now, the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), has published a new Position Statement on indications for surgery for obesity and weight-related diseases, published in Obesity Surgery. Recommendations are graded base… Read More »
