In a recent study, Jenny Craig and the Pennington Biomedical Research Center evaluated the effect of time-restricted eating on weight loss in patients with obesity. Participants were randomized to 14:10 or 12:12 time-restricted eating windows and prescribed a nutrition plan and exercise that included counseling. The LEVL device was used by participants to measure breath acetone, which provided a personalized indication of fat metabolism and allowed remote monitoring of study compliance. These breath acetone data are expected to be published in a follow-on article.
The LEVL device measurements also provided encouragement – 85% of surveyed participants found that the LEVL breath acetone measurements kept them accountable and motivated during the study.
“Dieting without LEVL is like driving with no windows to see out of.”
“Higher measurements equated to greater loss, so it minimized my willingness to cheat, take extra bites, or eat anything off plan.”
“Having LEVL helped me know if I was on track.”
