One variable of interest in Paoli and colleagues’ study was excess postexercise oxygen consumption, or EPOC. This represents the oxygen consumption, or energy expenditure (above the baseline, or pre-exercise, level), that occurs after an exercise bout. It is sometimes called “after-burn,” implying the burning of calories after the workout.
We are taught that weight loss is simply an equation of calories in versus calories out. If only it were that simple. There is no magic formula for weight loss, of course, but researchers have developed many mathematical models to help us better understand how the body sheds weight. This article examines major concerns associated with these calculations (they are far from perfect) and then discusses simpler solutions that empower all of us to confront one of the most vexing issues of our times.

Thank you for including my voice in the Tricks of the Trade column [January 2014] that discussed body image. Many people have contacted me about the issue, tell- ing me I am an inspiration to them. They want my advice on how to get through this size-zero world living as a plus-size trainer. Wow, I am overwhelmed by the thanks I am receiving. Trainers and everyday women have appreciated my story and say they hope one day to inspire as I am doing. Thank you. I can’t tell you how much this means to me.

Body mass index is often used to determine health status and disease development potential. However, researchers from the Mayo Clinic have discovered that waist size can be a significant predictor of future problems—even among people in healthy BMI ranges.
The scientists culled data from 11 studies that included 650,386 white adults aged 20–83. At a 9-year follow-up, 78,268 participants had died.
As obesity continues to maintain a stranglehold on the teenage population, experts search for solutions to the potentially fatal disease. When it comes to exercise, a combination of cardiovascular and strength training is best, according to researchers from São Paulo.

According to the American Sleep Apnea Association, sleep apnea affects more than 18 million Americans. If untreated, the condition—which often affects overweight and obese individuals—can result in heart disease, stroke and diabetes. Recently, researchers learned that even a minimal amount of weight loss may prevent the progression of— or even cure—sleep apnea for the long term.
