You may want to review your digital device usage. New research shows that people who mindlessly switch between a smartphone and a tablet or other digital devices are likely to have an increased susceptibility to food temptations and lack of self-control, potentially leading to weight gain. Researchers from three American universities conducted the inquiry to examine whether links exist between obesity and use of digital devices.Read More
Did you know that dieting is ineffective at best and counterproductive at worse, with up to two-thirds of dieters regaining more weight than they lose (Mann et al. 2007)? Isn’t there a better way to eat healthfully?
One option is intuitive eating, which forgoes dieting and focuses on driving long-term improvements in your relationship with food. “Intuitive eating is the ability to read, interpret and follow your internal cues regarding the right amount of food for your body,” says Krista Scott-Dixon, PhD, curriculum director at Precision Nutrition.Read More
Studies have shown that people with obesity have a blunted sense of taste, so they have to eat more richly flavored foods (more sugary and higher in fat) to glean as much sensory satisfaction from a meal as their leaner peers. This could help in understanding why heavier people have a hard time losing weight.Read More
Weight Watchers® set off a furor early this year when it announced plans to launch a free program for teens.
As we are in the midst of a childhood obesity epidemic, critics pounced: Is a company named “Weight Watchers” that encourages weekly weigh-ins the proper vehicle for helping teens improve their health? Will the company trigger the development of an eating disorder in some teens? Is this just a ploy to lure new lifelong customers?Read More
No wonder social media feeds are packed with pictures of overflowing smoothie bowls: It appears people feel the types of foods they consume play a bigger role in their health goals than the volume they eat. As a result, a study from Vanderbilt University published in Management Science suggests that those who are trying to maintain a healthy body weight or wishing to shed a few pounds might be prone to overeating “healthy” items like nuts, granola and avocados. The upshot: The public should be educated about practicing portion control—for foods of all kinds.Read More
New research suggests that endurance exercise positively affects the gut microbiome, but only for lean individuals and only for as long as exercise continues. Researchers at the University of Illinois at Urbana-Champaign conducted the study with 32 sedentary men and women—some lean, some obese. The purpose was to explore the impact of endurance exercise on the composition, functional capacity and metabolic output of gut microbiota. Investigators collected samples from the subjects before and after 6 weeks of exercise, then after 6 weeks of no exercise.Read More
Feeling stressed? You’re not alone! The trick is knowing what to do about it.
Research tells us that stress-relieving strategies include making a concerted effort to minimize stressors, engaging in meditation and physical activity, and nurturing strong social relationships.
That’s good advice, but it ignores the common plan that many of us resort to: the “comfort food” strategy.
It’s 10 p.m., you’re catching up on email, and it suddenly hits you: a Goliath-sized craving for chocolate-chunk ice cream. Findings in the International Journal of Obesity show why the evening hours pose such a high risk for overeating and unhealthy munching. For the study, researchers from Johns Hopkins University School of Medicine recruited 32 adults with excess weight who volunteered for two experimental protocols:Read More
People who suffer from frequent cravings for unhealthy foods might benefit from tapping into the power of the mind. A review of studies published in the journal Clinical Psychology Review concluded that practicing mindfulness can effectively quell a hankering for “vice foods” like candies and ice cream, making it easier to achieve health and weight loss goals.Read More
Here’s more reason to apply a battery of assessments when determining a client’s health status. Scientists have found that body fat percentage is a more accurate indicator of a person’s risk for prediabetes or type 2 diabetes than other popular measures like body mass index.Read More

Humans are never alone. Each of us co-exists with trillions of microscopic organisms that form the human microbiome, a complex web of life that’s analogous to earthly biomes such as deserts, tundra and rainforests.
The microbiome extends from deep within our bodies—even inside individual cells—to the skin and to all surfaces exposed to the external environment. It includes bacteria, viruses, yeasts and fungi that interact with the body’s systems, helping with digestion, immune response and a vast array of less-well-known bodily functions.
Body image issues in the fitness industry are nothing new. But the need for a more positive philosophy and more diverse perceptions of beauty is especially relevant right now. With rising competition from fitness technologies, social media stars who plug fitness, TV trainers and an increasingly crowded marketplace within our own communities, a nice body can (and should) only get you so far in this industry. We need to emphasize qualifications more than we already do.Read More
Expectations about body image in the fitness industry crop up in different ways for different people. Some fitness pros ruminate about body image quite often (every day or even every hour), perhaps taking extreme measures to alleviate concerns. Others never really give it that

For the first time ever, overeating is a larger problem than starvation among the world’s overall population (Buchanan & Sheffield 2017). Losing weight—and, perhaps more importantly, not regaining it—is a challenge facing millions of people worldwide. According to the World Health Organization (WHO), global obesity rates have nearly tripled since 1975. Further, 1.9 billion adults, 18 years and older, were overweight in 2016. Of these people, more than 650 million were obese (WHO 2017).Read More
Ozzy Osbourne was curious and decided to have his genome sequenced.
“Given the swimming pools of booze I’ve guzzled over the years—not to mention all of the cocaine, morphine, sleeping pills, cough syrup, LSD, Rohypnol . . . you name it—there’s really no plausible medical reason why I should still be alive,” he said in the Sunday Times of London in 2010.
“Maybe my DNA could say why.”
What is “normal” when it comes to eating food? Your definition might be based strictly on nutrition science, or it may be bound up in social constructs or a personal pathology. Here’s another definition: “Normal eating includes the ingestion of healthy foods, the intake of a mixed and balanced diet that contains enough nutrients and calories to meet the body’s needs, and a positive attitude about food” (Pereira & Alvarenga 2007). While this statement may seem a bit succinct for a complicated issue, it’s probably close to what we as fitness professionals tell our clients.Read More
