Skipping Meals, Fasting and Eating Meals Too Closely Together May Be Linked to Increased Mortality Risk – Neuroscience News

Summary: A new study links daily eating to mortality risk. Those over 40 who eat one meal a day have a higher mortality risk. Those who skip breakfast are at an increased risk of cardiovascular disease-associated death, and those who eat meals less than 4.5 hours apart have increased mortality risks.

Eating only one meal per day is associated with an increased risk of mortality in American adults 40 years old and older, according to a new study in the Journal of the Academy of Nutrition and Dietetics.

Skipping breakfast is associated with higher risk of cardiovascular disease mortality and missing lunch or dinner with all-cause mortality.

Even among individuals who eat three meals daily, eating two adjacent meals less than or equal to 4.5 hours apart is associated with a higher all-cause death risk.

“At a time when intermittent fasting is widely touted as a solution for weight loss, metabolic health, and disease prevention, our study is important for the large segment of American adults who eat fewer than three meals each day. Our research revealed that individuals eating only one meal a day are more likely to die than those who had more daily meals.

Among them, participants who skip breakfast are more likely to develop fatal cardiovascular diseases, while those who skip lunch or dinner increase their risk of death from all causes,” noted lead author Yangbo Sun, MBBS, Ph.D., Department of Preventive Medicine , The University of Tennessee Health Science Center, Memphis. TN, US. “Based on these findings, we recommend eating at least two to three meals spread throughout the day.”

The investigators analyzed data from a cohort of more than 24,000 American adults 40 years old and older who participated in the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2014. An ongoing, nationally representative health survey of the non-institutionalized US population , NHANES collects a wide range of health-related data to assess diet, nutritional status, general health, disease history, and health behaviors every two years.

Mortality status and cause of the 4,175 deaths identified among this group were ascertained from the NHANES Public-use Linked Mortality File. The investigators observed a number of common characteristics among participants eating fewer than three meals per day (around 40% of respondents)—they are more likely to be younger, male, non-Hispanic Black, have less education and lower family income, smoke, drink more alcohol, be food insecure, and eat less nutritious food, more snacks, and less energy intake overall.

“Our results are significant even after adjustments for dietary and lifestyle factors (smoking, alcohol use, physical activity levels, energy intake, and diet quality) and food insecurity,” said the study’s senior investigator Wei Bao, MD, Ph.D., Department of Epidemiology, College of Public Health, University of Iowa, Iowa City, IA, US. He noted, “Our findings are based on observations drawn from public data and do not imply causality. Nonetheless, what we observed makes metabolic sense.”

dr Bao explained that skipping meals usually means ingesting a larger energy load at one time, which can aggravate the burden of glucose metabolism regulation and lead to subsequent metabolic deterioration. This can also explain the association between a shorter meal interval and mortality, as a shorter time between meals would result in a larger energy load in the given period.

dr Bao commented, “Our research contributes much-needed evidence about the association between eating behaviors and mortality in the context of meal timing and duration of the daily prandial period.”

Meal frequency, skipping, and intervals were not addressed by the 2020-2025 Dietary Guidelines for Americans because the Dietary Guidelines Advisory Committee “was unable to find sufficient evidence on which to summarize the evidence between frequency of eating and health.”

Previous dietary studies and Dietary Guidelines for Americans have focused mainly on dietary components and food combinations.

Background

Previous dietary studies and current dietary guidelines have mainly focused on dietary intake and food patterns. Little is known about the association between eating behaviors such as meal frequency, skipping and intervals, and mortality.

lenses

The objective was to examine the associations of meal frequency, skipping, and intervals with all-cause and cardiovascular disease (CVD) mortality.

design

This was a prospective study.

Participants/settings

A total of 24,011 adults (aged ≥40 years) who participated in the National Health and Nutrition Examination Survey 1999-2014 were included in this study. Eating behaviors were assessed using 24-hour recall. Death and underlying causes of death were ascertained by linkage to death records through December 31, 2015.

Main outcome measures

The outcomes were all-cause and CVD mortality.

Statistical analyzes performed

Multivariable Cox proportional hazards models were used to estimate adjusted hazard ratios (HRs) of all-cause and CVD mortality.

results

During 185,398 person-years of follow-up period, 4,175 deaths occurred, including 878 cardiovascular deaths. Most participants at three meals per day. Compared with participants eating three meals per day, the multivariable-adjusted HRs for participants eating one meal per day were 1.30 (95% CI 1.03 to 1.64) for all-cause mortality, and 1.83 (95% CI 1.26 to 2.65) for CVD mortality . Participants who skipped breakfast have multivariable-adjusted HRs 1.40 (95% CI 1.09 to 1.78) for CVD mortality compared with those who did not. The multivariable-adjusted HRs for all-cause mortality were 1.12 (95% CI 1.01 to 1.24) for skipping lunch and 1.16 (95% CI 1.02 to 1.32) for skipping dinner compared with those who did not. Among participants eating three meals per day, the multivariable-adjusted HR for participants with an average interval of ≤4.5 hours in two adjacent was 1.17 (95% CI 1.04 to 1.32) for all-cause mortality, comparing with those having a meal interval from 4.6 to 5.5 hours.

conclusions

In this large, prospective study of US adults aged 40 years or older, eating one meal per day was associated with an increased risk of all-cause and CVD mortality. Skipping breakfast was associated with increased risk of CVD mortality, whereas skipping lunch or dinner was associated with increased risk of all-cause mortality. Among participants with three meals per day, a meal interval of ≤4.5 hours in two adjacent meals was associated with higher all-cause mortality.
