Abstaining from food three hours before bedtime could benefit heart health<\/a>, according to a recent study by Northwestern University.<\/p>\n

Extending an overnight fast for two hours, dimming the lights and not eating for three hours prior to sleep were shown to improve cardiovascular and metabolic health.<\/p>\n

The results were observed among middle-aged and older adults<\/a>, who are at a higher risk for cardiometabolic disease, as stated in a university press release.<\/p>\n

POPULAR INTERMITTENT FASTING DIETS MAY NOT DELIVER THE HEALTH BENEFITS MANY EXPECT<\/strong><\/a><\/p>\n

Time-restricted eating has recently surged in popularity due to its potential to improve heart health and aid in weight loss<\/a>, the researchers noted.<\/p>\n

“But most studies have focused on how long people fast, not how their fast lines up with their sleep schedule \u2014 a key factor in metabolic regulation,” the study authors wrote.<\/p>\n

The nearly eight-week study, published in the journal Arteriosclerosis, Thrombosis and Vascular Biology, examined 39 overweight and obese<\/a> participants between 36 and 75 years old. The intervention group was made up of 80% women.<\/p>\n

The participants completed either an extended overnight fasting intervention<\/a> \u2014 13 to 16 hours \u2014 or a “habitual fast” of 11 to 13 hours. Both groups dimmed the lights three hours before bedtime.<\/p>\n

EXERCISE AFFECTS THE HEART IN A HIDDEN, POWERFUL WAY BY REWIRING NERVES, STUDY FINDS<\/strong><\/a><\/p>\n

People who finished eating at least three hours before going to bed saw “meaningful improvements” compared to participants who continued with their usual eating routines.<\/p>\n

Those improvements included a 3.5% drop in blood pressure and a 5% drop in heart rate, as well as a “more natural drop” in both measures during sleep, which is “an important sign of cardiovascular health<\/a>,” the researchers found.<\/p>\n

The fasting participants’ hearts also beat faster during the day when they were active and slowed at night during rest \u2014 a pattern that\u2019s linked to better heart health.<\/p>\n

Those who abstained from eating also had better daytime blood sugar control<\/a>, meaning the pancreas responded “more efficiently” when challenged with glucose, “suggesting it could release insulin more effectively and keep blood sugar steadier.”<\/p>\n

First author Dr. Daniela Grimaldi, research associate professor of neurology in the division of sleep medicine<\/a> at the Northwestern University Feinberg School of Medicine, commented on these findings in a statement.<\/p>\n

“Timing our fasting window to work with the body\u2019s natural wake-sleep rhythms can improve the coordination between the heart, metabolism and sleep, all of which work together to protect cardiovascular health,” she said.<\/p>\n

Grimaldi noted that she and her fellow researchers were “genuinely excited” about the consistent improvements shown.<\/p>\n

“Seeing that a relatively simple change in meal timing could simultaneously improve nighttime autonomic balance, blood pressure<\/a> dipping, heart rate regulation and morning glucose metabolism, all without calorie restriction or weight loss, was remarkable,” she told Fox News Digital.<\/p>\n

Grimaldi noted that the three-hour pre-sleep fasting window is “critical,” because that’s when melatonin rises and the body transitions toward sleep, “a period when eating disrupts metabolism.”<\/p>\n

YOUR BEDROOM TEMPERATURE COULD BE PUTTING YOUR HEART IN SERIOUS DANGER, STUDY WARNS<\/strong><\/a><\/p>\n

Sleep expert Dr. Wendy Troxel, RAND Corporation senior behavioral specialist and a licensed clinical psychologist in Utah, emphasized the study’s high adherence rate, at nearly 90%.<\/p>\n

“High rates of compliance suggest that this approach may be both feasible and sustainable in real life and could have a demonstrable impact on improving cardiometabolic health,” Troxel, who was not involved in the study, told Fox News Digital.<\/p>\n

The findings add to growing research linking sleep and circadian rhythms to cardiovascular health, she added. “In fact, the American Heart Association now recognizes healthy sleep<\/a> as one of its Life\u2019s Essential 8 pillars for heart health.”<\/p>\n

Looking ahead, the researchers plan to expand the study to larger, multi-center trials to determine whether the benefits persist or “translate into reduced cardiovascular events or diabetes.”\u00a0<\/p>\n

Future studies could also explore the potential benefits of extending time-restricted eating.<\/p>\n

“We also want to test this specifically in people with hypertension or diabetes, [who] might benefit most,” Grimaldi shared. “And exploring how this combines with other behavioral interventions, like exercise or morning light exposure, could help us develop more comprehensive strategies for cardiometabolic health<\/a>.”<\/p>\n

The high percentage of women<\/a> poses a study limitation, as it limits the ability to draw “definitive conclusions” about gender differences, Grimaldi acknowledged.<\/p>\n

“We need studies powered to examine sex differences,” she said. “Additionally, our 7.5-week intervention was long enough to show physiological changes, but not long enough to see effects on weight or long-term health outcomes.”<\/p>\n

Northwestern University reported that only 6.8% of adults in the U.S. had optimal cardiometabolic health from 2017 to 2018.<\/p>\n

These conditions can lead to chronic illness, including type 2 diabetes, cardiovascular diseases and non-alcoholic fatty liver disease. Heart disease is the No. 1 global killer, according to the CDC.\u00a0<\/p>\n<\/div>\n
