Anyone who’s achieved a weight loss goal, then watched his or her waistline expand over the following months, can attest to the incredible frustration of seeing hard-earned results fade away. The reasons for weight regain are many, but a big contributing factor is how the body tends to recognize missing pounds as a need to slow metabolism and burn fewer calories, making it harder for people to maintain weight loss.Read More
It happens to the best of us: You walk into the supermarket intent on filling your cart with nothing but healthy foods, only to be blindsided by the oh-so-enticing smell wafting from the bakery aisle. It turns out you can blame your hormones for why you’re standing with muffins at the checkout line, according to re?¡search in Cell Reports.Read More
It’s 2 a.m. Your 3-month-old son is screaming at the top of his tiny lungs, waking up everyone in the household. You lie still, pretending to be asleep, knowing it’s your turn to get up and console your little one. Then you feel a nice solid push in the back: Your partner knows your game—and is not playing.Read More
Resistance training does much more than build strong muscles and bones. Research in the past few years has confirmed that lifting weights changes human metabolism in ways that improve health and well-being. That’s good news for clients with type 2 diabetes, high blood pressure, obesity and high cholesterol levels.Read More
The hypothalamus occupies little real estate in the brain, but it houses nuclei critical to many of the body’s regulatory functions. Situated just beneath the thalamus, it keeps the body in homeostasis by controlling the sleep-wake cycle, body temperature, hunger and thirst, sex drive, fluid balance, emotions, blood pressure, and heart rate (Johnson 2018).Read More
Spending a third of our lives horizontal, hallucinating and paralyzed may sound like something from a scary sci-fi movie—but, in reality, these are good things. It’s all about sleep, and getting enough of it is essential.Read More
As a fitness pro, you no doubt value the restorative properties of professional massage. However, finding time for a massage may sometimes be difficult. That’s why it’s helpful to use self-care massage tools for preventing or treating pain or imbalances in the body. While these tools don’t provide “massage” as such (and can’t replace a professional therapist), the best ones offer some of the same benefits.Read More
It’s time for Americans to shift their focus from calories, macronutrients and micronutrients to taste, culture and mindfulness. After all, our preoccupation with dieting and health fads has us restricting foods, chasing unsustainable weight loss goals and feeling bad about our nutrition choices—but all we have to show for it is rising rates of overweight, obesity, diabetes and heart disease.Read More

People who like to work up a sweat should definitely have proper hydration practices on their mind. A review in Medicine & Science in Sports & Exercise found strong evidence that athletes who lose more than 2% of their body weight in fluids—all too common in prolonged bouts of sweaty exercise—suffer noticeable declines in mental performance. The review (a meta-analysis of previously published research) noted declines in attention, motor coordination, and the executive functioning your brain needs to focus, organize and remember details.Read More
Over the past few decades, researchers have shown that an individual’s
genetic makeup can play a big role in his or her propensity to gain weight and keep it on. For instance, one person may have a gene that makes him more efficient at converting food calories into body fat, while someone lacking this gene can apparently eat as much as she wants without packing on a single pound. Maddening for some, to be sure. But now it seems that dietary choices may have the power to override certain genes associated with body weight.
Moms-to-be should visit the fishmonger more often. In a study published in the journal Pediatric Research, scientists in Finland collected nutrition information from 56 pregnant women using food diaries; the scientists then measured blood levels of long-chain polyunsaturated fatty acids (aka omega-3 fats) in both mothers and babies when the newborns were 1 month old.Read More
It appears that the way our brains are hardwired can play a big role in eating habits and long-term weight loss success, according to research published in the October 2018 issue of Cell Metabolism. In the study, Canadian researchers ran MRI brain scans on 24 people while showing them images of different foods. Participants then began a 1,200-calorie-a-day diet in a weight loss clinic.Read More
In literature, it has been known to curdle, boil and run cold. Yes, we’re talking about blood. A closer look at its function and composition reveals an interesting story about the human body. Blood travels through the circulatory system to deliver vital nutrients, oxygen and hormones to the body’s tissues, and it’s made up of four components: red blood cells, white blood cells, platelets and plasma (MSKCC 2017).Read More

You’re no doubt familiar with the Achilles tendon, named after the Greek demigod whose singular physical weakness brought him to his knees. But how much do you know about tendon functionality? When it comes to mobility, tendons are the unsung heroes of our anatomy. These tough yet flexible cords of fibrous tissue connect muscle to bone—unlike ligaments, which connect bone to bone.
Tendons are found throughout the body, to help facilitate movement. When a muscle contracts, the tendon absorbs some of the impact and pulls the attached bone into action.Read More
