If you’ve ever hit a wall during a long run, you know how brutal it feels. It happened to me during my first marathon and running the last 10k was beyond brutal. Your legs feel heavy, your energy plummets, and suddenly the miles ahead feel impossible. Most runners assume it’s a training issue, but more often than not it’s a nutrition issue. In this post, I break down exactly how to fuel a marathon (and long runs in general) with insights from registered dietitian and ultramarathoner Amy Goblirsch. From carbs per hour to gels vs. real food, here’s what you…
If you’ve noticed a shift in the yoga studio lately, it’s not just your imagination. A growing number of fitness-focused moms are trading in traditional bulky, sand-filled regular weight vests for sleek, quiet silicone weighted vests. Adding resistance to a yoga flow or a brisk cartwheel walk is a fantastic way to build bone density and burn extra calories. However, traditional gear simply wasn’t built with the mindful, multitasking lifestyle in mind. Why are moms silently choosing silicone vests for yoga practice? The shift toward silent, silicone-heavy vinyasa gear represents a larger movement among moms who focus on fitness…
Even people who meet the recommendations for fruits and vegetables rarely consume enough flavanols to match the levels associated with reduced cardiovascular risk, raising new questions about whether flavanol-specific dietary guidance is needed. Study: Adherence to dietary guidelines does not yield levels of flavanol intake associated with beneficial cardiovascular outcomes. Image credit: Tatjana Baibakova/Shutterstock.com A recent study in Food and Function investigated whether current dietary recommendations for fruit, vegetables and overall diet quality correspond to levels of flavanol intake associated with cardiovascular health benefits. Current dietary advice lacks specific flavanol targets Flavanols are a subclass of flavonoids, a group of…
How to deal with a breakup alone? How to get over someone? All around us we meet so many broken, dried up, broken souls carrying the pieces of their hearts. Crying in pain and feeling so sorry for themselves. Questioning their own efforts they had put into their relationships and losing their inner spark. How do you get over the loss of someone you loved? Let this blog deal with the spread, the rant and the return to soul breakers. How to deal with a breakup alone? Okay, now they’re gone. While I am writing this blog, I am not…
For decades, the fitness and diet industries have sold us a very specific, very narrow story of what exercise is supposed to be. We’re told it has to be grueling, that it has to happen in a gym for at least an hour, and—most damaging of all—that its primary purpose is to shrink our bodies. As an Inclusive Weight Registered Dietitian and Certified Intuitive Eating Consultant, I see the consequences of this narrative every day. Many of us have a fraught relationship with physical activity. We think of it as a chore, a punishment for what we ate, or a…
A study of 2,044 elderly Japanese people found that those with lower levels of vitamin C in their blood plasma tended to have lower gray matter volume in their brains, as well as lower connectivity between a collection of brain regions known as the default mode network. Haruka Nagaya of Hirosaki University in Japan and colleagues present these findings in the open access journal PLoS One on June 10, 2026. Previous research has found associations between diets higher in vitamin C and a lower risk of cognitive decline in older adults. However, few studies have directly examined plasma vitamin C…
Introduction: Understanding Glioblastoma and Metabolic Vulnerability On World Brain Tumor Daywe look at the latest reviews about its use ketogenic metabolic therapy (KMT) for glioblastoma (GBM)the most common malignant primary brain tumor in adults. This aggressive tumor has a poor prognosis, with a median survival in a sedentary position at approximately 14 months (1, 2). Despite its aggressive nature, glioblastoma presents a distinct metabolic vulnerabilitywhere it is highly dependent on aerobic glycolysis for energy. The ketogenic diet exploits this vulnerability by: Inducing nutritional ketosis. Reduction of glycolysis. Decreased availability of glucose for cancer cells. Allowing healthy cells to easily use…
Changes in the heart associated with marathon running vary by age, gender and training level, finds a synthesis of available data, published in the open access journal BMJ Open Sport & Exercise Medicine. However, it is unclear whether these changes represent normal physiological responses to endurance exercise or whether they are long-term (mal)adaptations, the findings show. Both low and extremely high levels of exercise are known to increase the risk of death, the researchers note. And endurance exercise causes acute changes in heart function and increases in substances, such as enzymes and proteins, indicative of tissue damage and inflammation, they…
You’ve probably heard of Ozempic or Wegovy. These are the injectable drugs that have become household names for weight loss and diabetes. Now, researchers are investigating whether these drugs, known as GLP-1 agonists or GLP-1 drugs, could treat everything from cancer and brain disease to depression, addiction and endometriosis. Some findings are truly fascinating. Others are oversold. Here’s what the science actually says. First, how do these drugs work? GLP-1 (glucagon-like peptide-1) is a hormone that your gut naturally releases after you eat. It tells your pancreas to produce insulin and signals your brain that you are full. These drugs…
New evidence suggests that fathers may influence their children’s obesity risk through changes in sperm, lifestyle habits, parenting behaviors and the family environment, prompting researchers to call for inclusive strategies that start even before conception. Study: The Role of Fathers in the Intergenerational Transmission of Obesity. Image credit: Creativa Images/Shutterstock.com A recent review published in the magazine Current obesity reports suggests that fathers influence obesity risk in their children through multiple interactive pathways that begin before conception. The findings suggest that childhood obesity prevention and research efforts should focus on both fathers and mothers. Expanding obesity research beyond maternal factors…
