I bet you have heard this already, late-night snacking is not good for you. Which is true. Now a recent research has shed more light into this topic.

An ongoing study at Perelman School of Medicine at the University of Pennsilvaniya in the United States, has found that compared to eating earlier in the day, and snacking on food after hours or delaying your dinner until late-night, has a negative impact on your weight, insulin, cholestrol levels, fat metabolism, and hormonal markers for heart disease and diabetes.

Throughout a two month period, nine healthy adults were asked to eat three meals and two snacks every day between 8 a.m. to 7 p.m. The participants returned after a few weeks off from the study, and was then asked to eat three meals and two snacks from noon to 11 p.m. 

Researchers then analyzed changes in the participants weight, metabolism, and calorie burn - the results indicated that delayed-eating caused their an increase in their negative metabolic profiles: weight, insulin, cholesterol, fasting glucose, and triglyceride levels. 

“We know from our sleep-loss studies that when you’re sleep deprived, it negatively affects weight and metabolism in part due to late-night eating, but now these early findings, which control for sleep, give a more comprehensive picture of the benefits of eating earlier in the day,” says the study’s lead author Namni Goel, PhD.

Moreover, due to the late-night eating, the participant's hormonal profile showed delayed peak in the appetite-stimulating hormone ghreling, which slowed the release of leptin - the hormone that lets us know when we are full. The opposite results were seen for the daytime eating plan. The implication is that eating earlier might prevent late-night snacking or overeating during the evening.

"Eating later can promote a negative profile of weight, energy, and hormone markers—such as higher glucose and insulin, which are implicated in diabetes, and cholesterol and triglycerides, which are linked with cardiovascular problems and other health conditions." says Namni Goel.
