According to a study, the number and quantity of foods were more significant predictors of weight gain or less than the interval between meals. The results of the study were published in the Journal of the American Heart Association, an open-access, peer-reviewed journal.
According to the study’s senior author Wendy L. Bennett, MD, MPH, an associate professor of medicine at the Johns Hopkins University School of Medicine in Baltimore, though, what’s known as a ‘punctual eating pattern’ Intermittent fasting – are popular, rigorously designed studies have not yet determined whether limiting the eating window during the day helps control weight.

This study examined the relationship between time from first meal to last meal with weight change. About 550 adults (18 years of age or older) with electronic health records from three health systems in Maryland and Pennsylvania were included in the study. Participants had at least one weight and height measurement registered in the two years prior to the study enrollment period (February–July 2019).
Overall, most participants (80%) reported that they were white adults. 12% self-reported as black adults. And about 3% self-identify as Asian adults. Most participants reported having a college education or higher. The average age was 51 years; And the average body mass index was 30.8, which is considered obese. The mean follow-up time for weight recorded in the electronic health record was 6.3 years.
Participants with a higher body mass index at enrollment were more likely to be black adults, older, have type 2 diabetes or hypertension, less education, less exercise, less fruit and vegetable intake, and longer duration since last meal. . A shorter time to sleep and from first to last meal compared to adults with a lower body mass index.
The research team created Daily24, a mobile application to list participants’ sleeping, eating, and waking times, in real time for a 24-hour window. Emails, text messages and in-app notifications encouraged participants to use the app more during the first month and again during “power weeks” — one week per month for the six-month intervention portion of the study.
Based on sleeping and eating times each day recorded in the mobile app, the researchers were able to measure:
time from first meal to last meal each day; Time elapsed from waking to first meal; and sleep interval from last meal. They calculated the mean for all data from complete days for each participant.
Although the study found that meal frequency and total calorie intake were greater risk factors for weight change than meal timing, according to the study’s lead author De Zhao, Ph.D., the results were directly Could not prove cause and effect. Division of Cardiovascular and Medical Epidemiology at the Johns Hopkins Bloomberg School of Public Health.
The researchers note that the study has limitations because they did not examine the complex interactions of meal timing and frequency. Additionally, because the study was observational in nature, the authors were unable to draw cause-and-effect conclusions. Future studies should work toward including a more diverse population, as the majority of study participants were well-educated white women in the mid-Atlantic region of the United States, the authors wrote.
The researchers were also unable to determine the intention to lose weight among study participants prior to their enrollment and could not rule out the additional covariates of any existing health conditions.
According to 2022 statistics from the American Heart Association, 40% of adults in the United States are obese. And the association’s current diet and lifestyle recommendations to reduce the risk of heart disease include limiting overall calorie intake, eating healthy foods and increasing physical activity.
2017 American Heart Association Scientific Statement: Meal Timing and Frequency: Implications for Prevention of Cardiovascular Disease No clear preference for frequent small meals or intermittent fasting. He noted that irregular patterns of total caloric intake appear to be less conducive to body weight and optimal cardiovascular health. And, changing meal frequency may not be useful for reducing body weight or improving traditional cardiometabolic risk factors.
