Does eating closer to sleep time affect weight loss/body composition?

Does eating near bedtime really contribute to fat/weight gain?

I'm asking because my schedule tends to push me towards more late dinners (as in eating an hour or two before bed). Is this problematic?

It's an old wive's tale that eating late makes you gain more weight. There is no decent evidence behind such an assumption, although in the larger scheme of things, anything that effects sleep could potentially contribute to weight gain or loss. Good sleep could contribute to better weight control, but I have never had any problems eating and then sleeping soundly. IMO, it's very natural to eat a big meal and then take a nap. My advice would be to eat when it works for you and not worry about if it is late or not.

Well, I think this is generally true, with one caveat. Growth hormone, which stimulates tissue repair, is most active in the first few hours of sleep, and it is inhibited by high levels of blood glucose. So it may be detrimental to eat a lot of carbohydrate just before bed. – Ambimorph Jan 10 2011 at 13:38

Ambi hit the nail on the head, carbs before bed are not for everyday. In addition, most of the bedtime weight fainted are because people are eating an additional meal because of post darkness blue light stimulation etc. – Stephen-Aegis Jan 10 2011 at 17:27

I skipped breakfast, worked out before lunch, ate a small meal(if I had carbs this is where they went), then feasted an hour or two before bed.

Intermittent fasting works.

Workouts while fasted are vital!

Meals before bed, with no sugar/limited carbs made me sleep like a king.

Could you define "limited carbs"? About 3 or 4 times a week I play sports, then feast (usually zero carbs), and have 2 or 3 glasses of wine. I'm not sure the carb content of dry red wine but I've seen it listed at 3 or 4 grams. Would you consider that a "limited carb" dinner? – wjones3044 Jan 10 2011 at 17:56

Red wine is one of my permanent cheats. I have 1-2 glasses 5x week. Don't stress over it at all. For lunch post workout I eat a tuber or two with my meats. Dinner is usually alot of meat with a small veggie garnish. – Stephen-Aegis Jan 10 2011 at 20:02
Hi Stephen-Aegis: What is your workout/eating schedule like on non-fasting days? or do you only have two meals per day? – gimmeMoreLiver May 16 2011 at 4:16

I did find this:

http://news.bbc.co.uk/2/hi/health/8234386.stm

One group of mice ate at times when they would normally be asleep. They put on twice as much weight.

On mice I know, but interesting I think.

I wish I could find the original study instead of just a review of it. One issue is that bad sleep has been well documented to cause quite a bit of weight gain. Could be the act of waking up the rats in the middle of their sleep cycle was the main prob. It would be like if I ate a bunch of my meals in the middle of the night but didn't eat during the day. That is enough to majorly screw up the circadian cycle. PLus they are extrapolating a lot to spin this to assume that just eating dinner a tad later is also bad. – Eva Jan 11 2011 at 3:09

I often eat big meals right before bed, but lately I've been eliminating carbs from my last meal, where I would normally eat a piece of fruit or equivalent. I figure I'll have a really low draw on glycogen stores when I'm sleeping so I won't need to eat carbs late at night. Not sure if it's sound logic or not, but I continue to feel great so I'll continue this practice.

Sounds good -- see my comment to Eva. – Ambimorph Jan 10 2011 at 13:38

Hasn't been a problem for me. Sure, fractionally more fat gets stored than if you ate earlier and went for a walk. But, you burn it off later on. Anything we eat that doesn't go to structure, energy, waste or heat ends up stored to be used later on. So, all that matters is the total amount you eat and when has less to do with it. That being said, some report marginal body comp advantages to long fasting periods. I eat twice daily, essentially the lunch and dinner IF plan, but dinner ends up close to bed time.

Your body will automatically maintain its setpoint, so any alterations in fat storage will be conpensated by hunger/craving levels. – Eva Jan 11 2011 at 2:59
Right, I speculate that a healthy metabolism will attempt to autoregulate in the face of overfeeding. If we allow ourselves an opportunity to, say, increase activity or decrease food intake subsequently. I imagine we can very easily override this possible autoregulation with learned behaviors. – stoic Jan 11 2011 at 18:47

I would consider skipping dinner if you're not eating out/socialising under these circumstances. A light meal that is ideally low carb, low protein, but fat rich is an option if going without dinner is unthinkable. It's not only about weight loss, but intermittent fasting can really help with melting body fat in any case. Intermittent fasting, and a prolonged ketogenic diet will help you reset your set point, which is not something one should see as fixed.

I personally sleep better when I've not eaten within 2-3 hours of sleep, but this has more to do with TEF and the fact that I really have trouble sleeping if I'm too warm.

yes, taking meal at late night directly affects weight, as after taking meal one should do some physical work like walking or something, it helps much in digesting food but if you will just sleep after your meal then the food will not be able to get digested and will cause problem like weight increase and insufficient digestion. So take your night meal in evening or at least two hour before you sleep.

Hello!!. I am not sure about eating near to bedtime contribute fat/weight gain. But it is a fact that the major issue that people facing today is Weight loss. But now a days there are many wealth loss program like the Tryfoodlovers.com that would make you slim and fit with the perfect body you wish to see yourself. It all depends on your sleep schedule .Just try to do it a couple of hours before you go to bed so your food can digest properly. I'll probably have 8-8:30pm which is a good time to have dinner.

After not being able to lose weight on Paleo for six months (I only have about 15 lbs to go to reach "ideal weight"), I have recently started incorporating the Carb Addicts Diet (Drs. Heller), where you skip breakfast, or have only protein and non-starchy veggies for breakfast and lunch, and then eat whatever you want, relatively speaking, within one hour at night. I still stick to paleo foods, with the occassional cheat during my hour. I've finally been able to loosen my belt after only a week. I haven't read the book yet but did read all the reviews on Amazon.
