Eating Dinner Late at Night May Cause Weight Gain


Consuming a late meal may add to weight gain and high blood sugar level, according to a small research study published in the Endocrine Society’s Journal of Medical Endocrinology & Metabolic Process.

Consuming a late meal might contribute to weight gain and high blood sugar level, according to a little research study.

Over 2.1 billion adults are estimated to have obese or weight problems that make health issues like diabetes and hypertension most likely. Some studies recommend that taking in calories later on in the day is associated with obesity and metabolic syndrome.

“This study sheds new light on how eating a late dinner worsens glucose tolerance and reduces the amount of fat burned. The effect of late eating varies greatly between people and depends on their usual bedtime,” said the study’s corresponding author Jonathan C. Jun, M.D., of the Johns Hopkins University School of Medicine in Baltimore, M.d. “This shows that some people might be more vulnerable to late eating than others. If the metabolic effects we observed with a single meal keep occurring chronically, then late eating could lead to consequences such as diabetes or obesity.”

The researchers studied 20 healthy volunteers (10 guys and 10 women) to see how they metabolized dinner eaten at 10 p.m. compared to 6 p.m. The volunteers all went to sleep at 11 p.m. The scientists found that blood sugar levels were greater, and the quantity of ingested fat burned was lower with the later meal, even when the very same meal was offered at the two various times.

“On average, the peak glucose level after late dinner was about 18 percent higher, and the amount of fat burned overnight decreased by about 10 percent compared to eating an earlier dinner. The effects we have seen in healthy volunteers might be more pronounced in people with obesity or diabetes, who already have a compromised metabolism,” said the study’s first author Chenjuan Gu, M.D., Ph.D., of the Johns Hopkins University.

This is not the first study to reveal impacts of late eating, but it is one of the most comprehensive. Participants wore activity trackers, had blood sampling every hour while remaining in a laboratory, underwent sleep research studies and body fat scans, and consumed food that contained non-radioactive labels so that the rate of fat burning (oxidation) could be figured out.

“We still need to do more experiments to see if these effects continue over time, and if they are caused more by behavior (such as sleeping soon after a meal) or by the body’s circadian rhythms,” Jun said.
