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.

It may sound counterintuitive, yet new research from the University of Missouri, Columbia, suggests that eating fewer, larger meals may prove healthier for obese women than eating smaller meals more often. More specifically, consuming three substantial meals per day instead of six small meals may decrease obese women’s risk of developing heart disease.
