If you're still hungry, can you really be overeating?

...Also, over time, I think people may be able to train/change their satisfaction indicators.

I think so too - and at the risk of oversimplifying it, I think it's a matter of learning to differentiate between "satisfied" vs. "completely stuffed". I also think part of it is learning what foods induce satiety, which is a very individual thing.

You're probably right in your possibly overly-simplified interpretation of it. Like it's a change from believing physically stuffed = stop eating to satiated = stop eating. This also necessitates a change from looking for foods that physically fill you up while being as low-calorie as possible to looking for foods that are satiating and of an appropriate calorie density to reach your target while also being sufficiently satisfying...all of which I believe are wonderful arguments for accurately and consistently tracking (regardless of whatever it is you're eating at the moment), because this data is incredibly valuable to "breaking the code" and figuring out what works for you as an individual.

(That said, personally, I believe that people are more similar than different once they actually figure it out, but self-experimentation and data-keeping are far more useful to actually figuring it out than just imitating what you believe others are doing.)

Yes. it takes about twenty minutes for your stomach to signal to arted eatinheard ofgheardheardg smaller portions, your stomach is a bit enlarged, and so it has to shrink to suit your smaller portion sizes.

That 20min thing is a myth.

I know if I stop eating while I am still hungry and wait 20 minutes, my hunger often stops or lessens and if I dont stop I could have easily chowed down 500 more calories so I dont know if its a myth or not but it works quite often for me

I wouldn't disagree with that. I am challenging "it takes 20mins for your brain to receive the signal." Imagine a 32oz milk shake with the fattiest ice cream and whole milk chugged down. You will be full within a few minutes.

It's not a myth.

I think what was being discussed was this point.

This article says nothing about "20 minutes" at all.

It's not an instant adjustment to the food you eat. That should be common sense. Just one example.. people who eat slower are generally thinner than people who eat fast. Because it takes time for the chemicals to interact and transmit satiety and pleasure. I'm not debating a 20 minute-not-a-second-longer-not-a-second-less, but to think it's an instant process is quite frankly, insulting. If it was instant, people wouldn't over stuff themselves then feel like they are going to burst a short time later saying "I can't believe I ate that much."

Or some people just don't care and keep on eating. I am going back to the milkshake example. If you can chug one down in 1 minute which is about 1000-2000 calories. You're telling me you can sit there and drink 20 of them since it takes time for your body to get the signal you're full.

No, like I said before, and you admitted to, filling your stomach regardless of calorie content will send a signal to stop eating. It's not the same thing we're talking about here. Ever take the gallon of milk challenge? Ever try to chug a gallon of water straight? You're going to throw it up because your stomach can't hold that much. COMPLETELY different signals to stop eating! It's like you are throwing common sense out the window and arguing semantics with straw man arguments in an effort to "be right."

Oh, and "some people don't care and keep eating" is the answer and not study after study that shows in general people who eat slower also eat less. My bad.. what are your credentials again?

Your stomach can hold it. Water has the density of 1g/ml. 3.68 liters per gallon I believe. Look up the volume capacity of the stomach. I'm sure you heard of water poisoning. People sometimes chug 2 gallons if not more. You want me to post studies on common sense? That's like saying posta study that states 2+2=4. This stuff is pretty basic.

My credentials?
NASM CPT, currently majoring in biochemistry and of course my Weght loss of over 135 lbs.

Something else to consider...our bodies do not necessarily need the same amount of calories each day, and I'm not just talking about exercise calories for that particular day. Our bodies don't automatically reset at midnight every night...so if you feel like you need to eat more on one day occasionally, then try it. If the scale starts moving up in a way that you don't like (or more importantly, your measurements start moving in a way you don't like), then make the necessary adjustments. Until then, why not try listening to your body cues? Perhaps your signalling system isn't broken and will serve you just fine.


ETA: Whoops, didn't realize I was posting this in the middle of a broscience battle. My apologies for the C-C-C-Combo Breaker!

Broscience lol.. I'm sorry I guess I missed the links in your posts to support your opinion, or your qualifications. My bad.

You didn't miss my links, I just didn't post any...

...so don't waste any more time looking for them...because they aren't in there.

That said, I'm sticking to my previous evaluation that the discussion I inadvertently posted in the middle of was more broscience than it was actual Science!.

Oh, and that's still just my personal opinion...so I won't be including any links, studies, qualifications, etc.

ETA: Looks like I quoted before the edit. Just the same, congrats on your n=1 results. Sounds like it's working great for you. That said, be careful that you don't make the incredibly common mistake of assuming that whatever worked for you is precisely what will work for everyone else...or that you have successfully isolated the specific variables that led to your (or others') results.

Just another opinion, just like I thought. Have a great day :-)

Yes. it takes about twenty minutes for your stomach to signal to your brain that it's full. Plus, if you've just started eating smaller portions, your stomach is a bit enlarged, and so it has to shrink to suit your smaller portion sizes.

That 20min thing is a myth.

I know if I stop eating while I am still hungry and wait 20 minutes, my hunger often stops or lessens and if I dont stop I could have easily chowed down 500 more calories so I dont know if its a myth or not but it works quite often for me

CCK: When you eat, food enters and fills your stomach and then travels to the intestinal tract. As the food is digested and the body’s cells are fed, a chemical called cholecystokinin (CCK) is released, turning on feelings of fullness and turning off the appetite."

It takes 30 minutes or more for food to even get broken down in the stomach and sent to the small intestine. You are talking about filling your stomach to capacity, which is an entirely different signal than turning off the chemicals that signal hunger.

Some christmas education

So that explains CCK, but that ignores both leptin and insulin, which also suppress appetite, and also react much quicker. CCK's appetite suppressing effect is really minor at best, it's main function is basically to turn on the digestive system to start digesting food, leptin and insulin are the main hormones that really control satiety. CCK basically suppresses appetite when your nauseous or anxious, it's more part of the fight or flight reflex rather than normal hunger/satiety.

Since you asked I'll quote some more of the article, which you obviously didn't read, and put it here so you have more info to cherry pick from

"The breakdown products of foods — amino acids from protein, fatty acids from fat, and glucose from carbohydrates — regulate hormones such as insulin, which affect the process at a cellular level. They send messages to the brain telling it that fuel is needed.

When the body needs nourishment, neurotransmitters are released. One neurotransmitter called Neuropeptide Y (NPY) is important in sending messages to various parts of the brain.

Scientists have recently identified two chemicals — ghrelin and leptin — circulating in the blood that communicate with NPY.

Ghrelin and glucose: According to the theory, low levels of glycogen and low blood sugar levels stimulate a spike in ghrelin and NPY’s activity in the hypothalamus. As NPY is stimulated, your desire for sweet and starchy foods goes up. And when ghrelin rises, so does appetite.

While you sleep, your glycogen and blood sugar stores are used up, causing the brain to release NPY. Skipping breakfast increases NPY levels so that by afternoon, you’re set up for a carbohydrate binge. This craving for carbs is not the result of a lack of willpower; it’s an innate biological urge at work.

The leptin link: After eating, leptin levels increase and inhibit the firing of NPY, so you feel full. If it has been a while since you’ve eaten, your blood levels of glucose are low and therefore leptin is low, and ghrelin is high.

The circulating levels of ghrelin peak at different times depending on when you have your heaviest meal. People who eat big lunches show ghrelin peaks at a different time than people whose main meal is at night.

In addition, these processes are at work:

The galanin-fat connection: Galanin is released when fat stores need filling up. In the evening, galanin levels tend to rise, which may be nature’s way of making sure that people have enough calories to last them through the night.

CCK: When you eat, food enters and fills your stomach and then travels to the intestinal tract. As the food is digested and the body’s cells are fed, a chemical called cholecystokinin (CCK) is released, turning on feelings of fullness and turning off the appetite."
