Cardio: How many runners will collapse this weekend?

The New York City Marathon is this weekend. It’s the world’s biggest race with more than 50,000 people running 26 miles non-stop. I wonder how many lives will be claimed this year. I’m not exaggerating. It happens every time… Last year in London, 31-year-old Army captain David Seath collapsed three miles from the finish line. He died a few hours later. A couple years before that, two runners — ages 31 and 35 — died during a marathon in Raleigh, North Carolina. I was unfortunate enough to witness this pattern firsthand… About 30 years, I provided emergency care for marathon runners. At one race, I saw a thin, young man fall to the ground just feet from our emergency aid station. His heart was beating erratically as we placed an oxygen mask over his blue lips. Seconds later, another runner arrived at our station and keeled over. He was dizzy, weak and scared. He had a dangerously erratic heartbeat. This man was only in his early 20s. The sad part is that marathon runners think they’re getting healthy by training for these long-distance runs. But the truth is, this kind of cardio is hurting your health. I once asked a long-distance runner I knew why he dragged himself out of bed at 5 a.m. every morning, laced up his running shoes and pounded away on the treadmill for 45 minutes. He told me he was tired of being overweight for years and never wanted to be fat again. I admire his dedication. But here’s the thing… Long-...

Despite what the mainstream media is telling you, sugar is not your enemy. Your body evolved to eat sweet foods. In fact, it’s how our ancestors knew a food growing in the wild was safe to eat and healthy. But your body did not evolve to eat starchy, high carbohydrate sugars from bread, pasta, cereal and other grains. Ever since we were told to eat low fat, this has been the bulk of the our diet. The result has been a modern epidemic of obesity and diabetes. At the same time, we face skyrocketing rates of dementia and Alzheimer’s. Big Pharma has been trying for decades to come...

We enjoy outdoor activities. My family will be coming over this year and I will fire up the grill for a delicious BBQ grass-fed beef. We’ll play games like badminton and horseshoes. Now while these games can be fun, they can lead to cuts and bruises. I want to aim you with an unconventional solution for those wounds.  For years now, sugar’s been a dirty word. It’s been blamed for everything from obesity, heart disease and diabetes to tooth decay and acne. But there’s something they don’t know.  Sugar’s better for you than all those artificial sweeteners and substitutes out th...

If I told you to eat what you love and cut back on your workouts if you want to lose weight, you might tell me I’m crazy. Diet and fitness “experts” certainly would. But their terrible advice about fitness and nutrition has led to the current obesity epidemic. Nearly 40% of Americans are now obese and nearly 70% are overweight. And the problem is only getting worse. A new study in the prestigious JAMA medical journal reports that more people are giving up on trying to lose weight.1 Researchers asked 27,350 overweight and obese adults whether they had tried to lose weight in the past 12 months. Since 198...

Losing weight is no easy task, and myths persist about how to do it—which end up making it even harder. To cut through the confusion, here are nine common misconceptions about weight loss and dieting, and what the science actually says. Myth #1: It’s impossible to lose weight It’s tough—just ask anyone who’s tried. But it’s not impossible. The National Weight Control Registry began keeping track in 1994 of people who lost at least 30 pounds and kept it off for a year or longer. Today, more than 10,000 Americans are part of the registry—with an average weight loss of 66 pounds, kept...

Obese people with a particularly high ratio of white to brown fat cells can have a hard time losing weight even when while dieting and exercising. Nanotechnology may soon help people turn white fat into brown fat, turning a daunting challenge into a much more manageable one. Researchers at Purdue University have now created a...

This article covers some of the advances of recent years in understanding the effects of varied forms of calorie restriction in humans. Efforts to quantify the results and find a good 80/20 point, at which most of the effects of longer and more stringent reductions in calorie intake are still evident, have resulted in practical outcomes. A number of quite interesting discoveries have been made along the way, such as the ability of longer fasting periods to clear out and replace damaged immune cells to some degree. The second phase of the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (C...

An alarming number of people worldwide are overweight or obese, posing significant health risks and leading to substantial individual and societal costs. The wide availability of highly palatable and calorically dense foods along with increasingly sedentary lifestyles make it easy to take in more calories than we burn. This leads to a calorie surplus that, over time, produces weight gain. It seems a simple solution to this epidemic should be to eat less and/or exercise more. However, the reality, as many dieters know firsthand, is not so simple.

Abstract Cold temperatures induce progenitor cells within white adipose tissue to form beige adipocytes that burn energy and generate heat; this is a potential anti-diabesity therapy. However, the potential to form cold-induced beige adipocytes declines with age. This creates a clinical roadblock to potential therapeutic use in older individuals, who constitute a large percentage of the obesity epidemic. Here we show that aging murine and human beige progenitor cells display a cellular aging, senescence-like phenotype that accounts for their age-dependent failure. Activating the senescence pathway, either genetica...

Abstract In all mammals, adipocytes are cells with abundant cytoplasmic lipids forming the parenchyma of the adipose organ. White adipocytes store highly energetic molecules to release them, in the form of free fatty acids to survive between meals. Brown adipocytes trough their unique mitochondrial UCP1 protein burn glucose and lipids to perform thermogenesis in order to survive in cold environments. A third type of adipocytes appears in the subcutaneous depot of the adipose organ of female mice during pregnancy and lactation: the pink adipocytes. The pink adipocytes are mammary gland alveolar epithelial cells wit...
