This point is most often made in the context of  debates between low-carb and low-fat diet  advocates. Those who say “A calorie is a calorie” in this context mean to suggest that macronutrient proportions are irrelevant to weight management (as long as one is getting enough of each to meet one’s basic health needs). All that matters is the total number of calories consumed, regardless of whether the plurality comes from fat or carbohydrate. Weight management is a simple game of math, these folks argue. To maintain your current weight, you need to consume the same number of calories your body burns each day. To lose a pound, you need to create a caloric deficit of approximate...

EY TERMS The amount of water and electrolytes (primarily sodium, Na+) lost as a consequence of thermoregulatory sweating during exercise can vary considerably within and among athletes. The reported range in sweating rate and sweat Na+ concentration ([Na+]) is ~0.5 to 2.0 L/h and ~10- 90 mmol/L, respectively. Sources of intra/interindividual variability in sweating rate and sweat [Na+] during exercise include exercise intensity, environmental conditions, heat acclimation status, aerobic capacity, genetic predisposition, body size/composition, protective equipment, sex, diet and hydration status. Sweat testing can be conducted to estimate individual sweating rates and sweat Na+ losses to help guide personalized fluid and electrolyte replacement recommendations. However, unstandardized methodological practices and challenging field conditions can produce inconsistent/inaccurate sweat testing results. Based on study findings to date, as well as some practical considerations, curren...
