A new study found that when we eat significantly impacts our energy expenditure, appetite, and molecular pathways in adipose tissue.
"In this study, we asked, 'Does the time that we eat matter when everything else is kept consistent?'" said Nina Vujović, Ph.D. "And we found that eating four hours later makes a significant difference for our hunger levels, the way we burn calories after we eat, and the way we store fat."
Vujović studied 16 patients with a body mass index (BMI) in the overweight or obese range. Each participant completed two laboratory protocols: one with a strictly scheduled early meal schedule, and the other with the exact same meals, each scheduled about four hours later in the day. In the last two to three weeks before starting each of the in-laboratory protocols, participants maintained fixed sleep and wake schedules, and in the final three days before entering the laboratory, they strictly followed identical diets and meal schedules at home. In the lab, participants regularly documented their hunger and appetite, provided frequent small blood samples throughout the day, and had their body temperature and energy expenditure measured. To measure how eating time affected molecular pathways involved in adipogenesis, or how the body stores fat, investigators collected biopsies of adipose tissue.
Results revealed that eating later had profound effects on hunger and appetite-regulating hormones leptin and ghrelin, which influence our drive to eat. Specifically, levels of the hormone leptin, which signals satiety, were decreased across the 24 hours in the late eating condition compared to the early eating conditions. When participants ate later, they also burned calories at a slower rate and exhibited adipose tissue gene expression towards increased adipogenesis and decreased lipolysis, which promote fat growth.

Try not to eat shortly before going to sleep, is what I take from this. Otherwise, how does your body know that lunch is really breakfast and supper is really lunch? It’s got to be that last meal immediately before sleeping that has the most impact, in my mind.
Nonsense.
Thanks! I need to lose weight.

Lessens the chance of Acid reflux as well.
Does the amount eaten late matter?
Meaning, in my opinion there is a difference between eating a meal or a full serving, vs eating 6 Pringles potato chips and an orange.
The chips and fruit are a Snack, not a meal or full serving.
I think they need to study the impact on sleep, I think there is a correlation affect between sleep and the late eating that is causing this study to be skewed.
Working from home these past two years, we’ve drifted to having dinner be around 4. This feels better for me.
So early bird specials are not only cheaper but more healthy. The next time my daughter complains about eating at 5, I’ll remind her of this important study.
OK, fwiw, but what worked (and works) for me was eating later in the evening. I shed 55 pounds eating one meal a day around or 8 or 9 PM.
Yes, I’m sure it’s better to eat mid day or whatever, but it was too easy to yield to temptation. Figuring that after 8 hours of sleep I had a good start on the days fasting. Can’t eat while I’m asleep, right? Then, skip lunch and dinner. After 23 to 24 hours combined with 800 to 1000 calories, maybe more - a pretty decent fat burn level is reached.
It’s really easy to slip into the “well, let’s just eat an hour earlier today. You’ve been good!”. And then the next day. Pretty soon the 8PM feed time is 5PM. Then 4PM .. 3PM..
Whatever time you choose, better stick with it.
For me, it’s important to get some quick, relatively hard to digest protein in my stomach as son as possible after I wake up. A hard boiled egg, chunk of cheese, can of tuna or some jerky seems to kick-start my metabolism and staves off hunger to the point where I only need a small lunch. If I dither and prepare an elaborate breakfast and eat any hour or more after I get up, it seems to not only slow me down, but for some reason I’ll be even more hungry when lunch time rolls around.
After a year of no weight change, switched to a b'fast of a granola - gnawing hunger for most of the morning, but got used to that about the time I started losing weight.
Lesson:
Small b'fast, decent size lunch, ONE SERVING dinner, (and nothing late).
I have a beautiful lunch every day around 1 pm packed with protein and veggies but prior i have a greek yogurt with fresh blueberries. For dinner maybe a small spinach kale salad and/or a few dark chocolate covered almonds and ice cream or frozen yogurt small size. 125 lbs. 5’7” female. No meat at all but fish yes.
Agree.. depends on what you eat and when you go to bed among all you other habits.
The body does not differentiate.
This study supports existing research which is already convincing, the ideal pattern for weight control is no eating after about 7 pm, with sleep hours within the normal range.
Obviously for people working off shifts, it gets more complicated. Which is why people working the late shifts tend to put on weight more than their day turn counterparts.
Adequate sleep (6-8 hours) is good for weight control, regardless of other variables. If you close the kitchen at 7, go to bed at ten and get up at six, you probably won’t be gaining much weight whatever else you do.
Don’t foreign countries like Italy eat dinner late like 9-10 p.m.? We eat around 7 and go to bed at 11 or 12 so I guess my fat is from something else. LOL
Just saying that if you eat heavily earlier in the day you will sleep earlier too, so what causes what?
