Italian scientists discovered a molecule for brain longevity – turned on by eating less.
Overeating might cause brain aging while eating less turns on a molecule that helps the brain stay young.
This work was led by Giovambattista Pani, researcher at the Institute of General Pathology, Faculty of Medicine at the Catholic University of Sacred Heart in Rome, directed by Professor Achille Cittadini, in collaboration with Professor Claudio Grassi of the Institute of Human Physiology. Our hope is to find a way to activate CREB1, for example through new drugs, so to keep the brain young without the need of a strict diet. Caloric restriction means the animals can only eat up to 70 percent of the food they consume normally, and is a known experimental way to extend life, as seen in many experimental models.
Moreover, Italian researchers have discovered that the action of CREB1 can be dramatically increased by simply reducing caloric intake, and have shown that CREB is absolutely essential to make caloric restriction work on the brain. Thus, our findings identify for the first time an important mediator of the effects of diet on the brain. Researchers at Mount Sinai School of Medicine set out to address this question and to understand another fact: exactly how does overconsumption accelerate age-related disease? An answer lies in a two-part study led by Charles Mobbs, PhD, Professor of Neuroscience and of Geriatrics and Palliative Medicine at Mount Sinai School of Medicine, published in the November 17 edition of the journal PLoS Biology.
On the other hand, a high calorie diet seems to accelerate age-related disease by promoting oxidative stress.
Dietary restriction induces a transcription factor called CREB-binding protein (CBP), which controls the activity of genes that regulate cellular function. The team found an optimal dietary restriction, estimated to be equivalent to a 30 percent caloric reduction in mammals, increased lifespan over 50 percent while slowing the development of an age-related pathology similar to Alzheimer's disease.
The researchers found that when dietary restriction was maintained throughout the worms' adulthood, lifespan increased by 65 percent and the Alzheimer's disease-related paralysis decreased by about 50 percent.
Michael Forster, of the University of North Texas Health Science Center and Raj Sohal, professor at the University of Southern California's School of Pharmacy, compared the life span and caloric intake of two genetically engineered strains of mice.
One strain of rats, the "fat strain" [above left],roughly doubles in weight over its adult life. By measuring the animals' metabolic rate, Sohal and his colleagues came to a deceptively simple conclusion: Caloric restriction is only useful when, as in the case of the obese mice, an animal eats more than it can burn off. In other words, it is better to skip the double cheeseburger than to turn up the treadmill after binging at Carl's Jr. Remember the initial study suggested that by developing drugs that mimic the protective effects of CBP -- those usually caused by dietary restriction -- scientists may be able to extend lifespan and reduce vulnerability to age-related illnesses.

If you have been reading my blog for a while you will know that when looking at scientific research for an answer to a question, I like to use human research. Since it looks like our desire to eat more when we are eating less is always going to be there and considering that the brain is the driving force behind these feelings, we need to revert to tips, tricks, and other strategies to fool the brain into thinking we’re not eating less. Great practical advice brother & I’m big on green types of tea (peppermint for me) on getting rid or lessoning the brains primitive response to hunger!! I also believe it’s a journey to understand how we react to hunger with the MIND TALK that occurs, that’s the real challenge!!! I am a big fan of a hard-boiled egg when I get too hungry to wait until my next proper meal.

The research appears the week of December 19, 2011 in the Proceedings of the National Academy of Sciences USA (PNAS). This finding is consistent with the fact that CREB1 is known to regulate important brain functions as memory, learning and anxiety control, and its activity is reduced or physiologically compromised by aging. In fact, if mice lack CREB1 the benefits of caloric restriction on the brain (improving memory, etc.) disappeear. The study examines how dietary restriction and a high-caloric diet influence biochemical responses.
Mobbs and his colleagues unraveled a molecular puzzle to determine that within certain parameters, a lower-calorie diet slows the development of some age-related conditions such as Alzheimer's disease, as well as the aging process. By developing drugs that mimic the protective effects of CBP -- those usually caused by dietary restriction -- scientists may be able to extend lifespan and reduce vulnerability to age-related illnesses.
It was the result of blocking CBP activation, which inhibited all the protective effects of dietary restriction, that confirmed to us that CBP plays a key role in mediating the protective effects of dietary restriction on lifespan and age-related disease." -- Dr.
Mobbs and his team looked at the other end of this process: What happens to CBP in a high-calorie diet that has led to diabetes, a disease in which glucose metabolism is impaired?


Mobbs hypothesizes that dietary restriction induces CBP by blocking glucose metabolism, which produces oxidative stress, a cellular process that leads to tissue damage and also promotes cancer cell growth.
If we can map out these interactions, we could then begin to produce more targeted drugs that mimic the protective effects of CBP." -- Dr. In a 2003 study, he and Forster found that caloric restriction begun in older mice -- both in "fat strains" and "leaner strains" -- actually shortened life span.
While I do everything possible in my writings and research to find ways to help you eat more food, still lose weight, improve your health, there is a limit to this. The bad news is that when you are dieting and eating less food you will always be hungry.Sorry to be the bearer of bad news here. Sort of like when you get a cut, it hurts for a little bit but then after a while your body stops transmitting the pain signal. I took an informal poll on the Naked Nutrition Facebook page to see what people are doing to suppress appetite and fight this hardwired hunger response.
Drinking Lots of Tea (Green, Black, Mate, etc) – While probably not as effective as all the ads on the internet claim, but tea has been used for hundreds of years as an appetite suppressant. Fiber, Fiber, Fiber – Taking advantage of the satiating effects of fiber is also very important.
Drinking More Water – While drinking water at a meal has not really been shown in scientific studies to make people eat less calories, it is still a widely used strategy by many people.
If you have something that works for you that wasn’t mentioned above please post a comment below so we all can benefit. I have a lot of problems with my diet at the moment, more due to being thrown in a situation where I no longer get to choose the food coming in the house. Yes, they have some calories – but they are nutrient dense and have just enough healthy fats to create tremendous satiety for a couple of hours.
Furthermore they do not develop, if not much later, Alzheimer’s disease and with less severe symptoms than in overfed animals. Nevertheless, the precise molecular mechanism behind the positive effects of an hypocaloric diet on the brain remained unknown until now. But why is it that some animals, like laboratory rats, can live as much as twice their normal life spans when they are fed very little food?
How the diet is restricted -- whether fats, proteins or carbohydrates are cut -- does not appear to matter. Human life could be extended to an average of over 100 years if this is applicable to our species.
Interestingly, dietary restriction triggers CBP for as long as the restriction is maintained, suggesting that the protective effects may wear off if higher dietary intake resumes. But the "lean strain" [above left], which never becomes obese, did not benefit from the caloric restrictions. However, Sohal said that obese individuals are probably better off cutting calories than increasing their exercise to make up for overeating. In order to lose weight effectively, we must create circumstances that minimize hunger and cravings. If you are not losing weight and want to lose 5, 10, or 15lbs you will need to eat less food than you currently are to make this happen.
Unfortunately, the human body’s response to hunger is not the same as its response to a paper cut.
People have a tendency not so enroll in studies that would force them to under eat for decade. What is really interesting is that if you take that same glass of water and use it to make a soup with the vegetables at that meal (so you are basically eating the same things just in a different form), studies show that you will then eat less – wild huh? Sugar free Jello is devoid of calories but the act of eating itself can help signal the brain that you should not be as hungry because you just ate. I have become my mothers carer which means my cash flow is very limited and so cannot buy a lot of my own food to help me lose weight.
Mike is known for transforming complex nutritional concepts into practical nutritional habits that his clients can use to ensure permanent weight loss and long lasting health. Mobbs and his team reduced the roundworms' dietary intake by diluting the bacteria the worms consume. Mobbs to conclude that a high-calorie diet that leads to diabetes would have the opposite effect of dietary restriction and would accelerate aging. CBP responds to changes in glucose within hours, indicating genetic communications respond quickly to fluctuations in dietary intake. If there is one thing that research has shown us about eating behaviors, it is that calories don’t matter. To try and help my situation and not eat so much of the regular diet going on in the house, I have been eating sprouted lentils to fill me up, cheap to buy and easy to spout.


In these types of roundworms, human beta amyloid peptide, which contributes to plaque buildup in Alzheimer's disease, is expressed in muscle, which becomes paralyzed as age progresses.
Choosing the right foods I rarely eat out, but I didn’t have a choice last night and decided to try a Burger King Whopper.
Ground flax can be easily added to lots of things, it full of fiber, omega-3s, and other phytonutrients. We are a very visually driven species, so seeing a big bowl of food that is low in calories (like Jello or a salad) will result in us thinking we ate a lot despite the fact that the actual amount of calories we ate weren’t that much.
I feel healthier since starting to eat them but I am not really sure of the calorie content, Does anyone happen to know the answer to this please? Mike holds a degree in biochemistry from Hobart College and a doctorate in nutrition from Pennsylvania State University. This model allowed researchers to readily measure how lifespan and disease burden were simultaneously improved through dietary restriction. In addition most fiber rich foods are generally not calorie dense foods which means that you can eat more without eating more calories. After eating, I checked its calorie content online and found that the Whopper without cheese contained 670 calories. It was shocking how many calories the thing contained for the amount of satiety it gave me. Certain foods bring much more satiety than others for the same calorie count and eating out all the time could make things very difficult. Stick to drinking water and you’ll be ahead of the game, allocate those calories to your meals and it will be much more filling.
I won’t go over sweets and pastries because it’s common knowledge that they have a terrible calorie to satiety ratio.
Instead, I’ll go over other common forms of carbs that are more filling (weight after cooking): 300 g of white bread = 795 calories 300 g of cooked pasta = 474 calories 300 g of white rice = 390 calories 300 g of baked potatoes = 279 calories 300 g of baked sweet potato = 270 calories For the same weight, potatoes contain significantly less calories than the other common forms of carbs. What to eat when it comes to protein Calorie for calorie, meat and eggs creates the most satiety by far. A pound of raw chicken thighs without skin and 11 eggs a day sounds like a lot of food, but it’s only around 1393 calories.
Here are some common forms of protein: 300 g of KFC’s Extra Crisp Chicken Tenders = 735 calories 300 g of chicken breasts roasted without skin = 495 calories 300 g of roasted chicken thighs without skin = 627 calories For the same weight, processed meats will generally contain higher calories (fat and msg are usually added to improve taste). Chicken tenders and chicken breasts are both white meat but tenders contain much more calories.
300 g of beef sirloin, lean only = 549 calories 300 g of pork centre rib loin chop, lean only = 654 calories 300 g of pan fried bacon = 1623 calories Beef and chicken are leaner and lower in calorie than pork.
Most people are surprised to find that eating this makes it easier to lose weight than high carb diets. 300 g of cooked eggs without fat added = 465 calories Eggs are fantastic in this regard, without a doubt, I find them to be more filling than any other food per calorie.
What to eat in terms of fat Condiments are often high in fat and they’ll raise the calories without adding much satiety.
The best thing about making food at home is that you get to control all of the ingredients that goes into your meal.
While fat is needed in your diet for healthy hormone production, the whopper had more than half of its calories come from fat, making it very inefficient at keeping you full. They are often recommended as snacks, but I actually don’t recommend snacking during a cut.
Improve your satiety with the right eating pattern In my opinion eating 5-6 meals a day is not a good way to lose weight.
You’re already eating at a calorie deficit, splitting whatever is left into 5-6 meals makes eating completely miserable. Eating 5-6 times throughout the day to raise the metabolism is a myth that has been addressed time and time again.
There is just no reason to do it unless you actually prefer eating a bunch of tiny meals throughout the day. The best option that I have found is to skip breakfast, drink coffee to suppress hunger and eat your 3 meals closer together.
It’s a style of intermittent fasting and my favourite benefits include: More time in the morning because you’re not preparing and eating breakfast Never hungry before bedtime Creates a lot more satiety overall If you have a 8-4 or 9-5 job, 2 of the meals can be prepared at home Sharing photos of epic meals that are about to be consumed is the hallmark of online intermittent fasting communities.
