Is it true that the human digestion system needs a startup in the morning?
Meaning that if you want to lose weight it can be beneficial to eat in the morning instead of skipping that meal?

Also does food eaten just before sleeping, result in more calorie absorption?

Edit: I'm not looking for medical advice, nor am I trying to lose weight.
I'm just curious if eating 3 meals differs from eating 2 meals (same total calorie intake).

Can you please rephrase the question so that it does not sound as asking for medical advice? –  nico Apr 26 '13 at 16:20
Since both medical advice and health advice are off-topic I think this should be closed or reformulated. –  fileunderwater Nov 24 at 9:27

When you are healthy, you digest and absorb most of the digestible nutrients and only small amount of them appear in the stool. If your intestinal motility or digestive enzyme activity or any other part of the digestion works slower from whatever reason (physiological, not pathological), the digestion may take longer, but is still very likely pretty much complete. If the digestion were not complete, nutrients (fats, proteins, carbohydrate) would reach the colon and trigger diarrhea. But you normally do not get diarrhea when you eat breakfast, right?

You lose weight when you burn more calories than you eat. Your body burn calories to maintain vital functions, to produce heat and to produce energy for muscles. I don't think, you can lose weight just by some trick.

So basically you are saying that it doesnt matter if I eat 3000 calories in one meal just before I go to sleep or eat 3 meals of a 1000 calories spread over the day? –  user1897 Jul 18 '13 at 11:24

Breakfast will prolong your life and can mean you end up weighing less while you do it, with a lower chance of being diabetic.

This effect is probably related to caloric restriction, where cutting back calories has been shown to prolong lifespan by up to 50% in animals tested from worms to primates. Eating a moderate breakfast lowers the sugars in the blood and turns down the tendency to store fat.

Breakfast seems to prime you for a healthy day.

Please define "breakfast"... Surely eating bacon and eggs in the morning is not the same thing as getting a cup of coffee with a couple of biscuits. –  nico Apr 26 '13 at 16:21
I think the studies cited here only care about how many calories and the glycemic index of what you eat. Its not usually done to break down diet studies into particular items. So better to have a piece of toast and a cup of tea rather than say three pieces of cake. –  shigeta Apr 26 '13 at 17:05
my point was that saying breakfast will prolong your life does not mean much if you don't define what's in the breakfast. –  nico Apr 26 '13 at 18:44
you have a point, but to connect a definition to the results reported, you also have to look at the study protocols to try to suss out the various definitions of breakfast. I mean they have shown prologation of life and better health, but not necessarily with the breakfast you are thinking of... –  shigeta Apr 26 '13 at 19:15
Exactly, so may I suggest a few edits to improve the answer? 1) Link to the original study rather than a report which just says it was "an English study"... 2) Rather than saying "breakfast will prolong your life" you should say "skipping breakfast is a risk factor for obesity" 3) Point out the caveats of this study: breakfast skipping is also associated to smoking, infrequent exercise, frequent alcohol use and low education level, so the link to obesity may not be direct, but rather and indirect effect of lifestyle. –  nico Apr 27 '13 at 7:57
