Not everyone uses text messages, but for those who do, fitness professionals can harness the power of technology to help clients get healthier, say researchers at Duke University.
Scientists followed 50 obese women who received either a daily text for weight loss intervention or used more traditional methodology, such as writ- ten food journals or computer-tracked journaling. Over 6 months, the 26 subjects in the texting group lost an aver- age of 3 pounds, whereas the 24 who journaled more traditionally actually gained 21⁄2 pounds.
You probably have clients who have been dieting most of their adult lives. A study published in the International Journal of Obesity (2013; doi: 10.1038/ijo.2013.138) shows that there may be a physiologic reason why diets could be a poor bet, especially for obese people.
Food journals can be a great tool to help you lose weight. Journals allow you to document everything you eat in a day in one convenient location. Scientific literature has established that keeping track of what you eat and drink is an effective tactic for making dietary changes.
You can record your food intake on paper or electronically. An effective food journal should include these basics:
Welcome to the holidays . . . the gift-giving, party-hopping, dessert-eating, over-indulging, stress-evoking frenzy! We all know it. The time from Halloween to New Year’s Day is precarious for health-conscious people and can throw anyone’s health routine out of whack.
Have you ever wished for a quick way to test whether a client is burning fat? Scientists from Researchers Laboratories in Yokosuka, Japan, believe they have found an answer—in the form of a portable breath analyzer device.
The researchers developed the device to measure acetone, “a metabolite derived from fat-burning [and] produced in the blood, that is expelled through alveoli of the lungs during exhalation.”
For anyone who wants to get slim or maintain a healthy body weight, reading food labels is widely considered a vital dietary strategy. Supermarkets have thousands of them, those black-and-white Nutrition Facts labels telling shoppers how many calories each portion of a product contains. Many recipes in magazines and diet books also indicate the calories you’ll take in with every serving. But now science is showing that not all calories are created equal and those numbers aren’t always, well, black and white.
