Today’s Re-Powering Information – The article below explains why you grab that cookie even though you know you shouldn’t eat it. It also explains why diets don’t work. The author also has a new book called “The End of Overeating”. I have not read it, but if you struggle with overfeeding, it may be worth the read.

Brain aches for food bathed in badness
THE WASHINGTON POST
WASHINGTON - He went in the middle of the night, long after the last employee had locked up the Chili's Grill and Bar. He'd steer his car around the back, check to make sure no one was around and then quietly approach the Dumpster.

Foods high in fat, salt and sugar alter the brain's chemistry in ways that compel people to overeat, says Dr. David Kessler, the former commissioner of the Food and Drug Administration.
If anyone noticed the man foraging through the trash, they would have assumed he was a vagrant. Except he was wearing black dress slacks and padded gardening gloves.
The high-octane career path of David Kessler, the Harvard-trained doctor, lawyer, medical school dean and former commissioner of the Food and Drug Administration, had come to this: nocturnal Dumpster diving. It took many of these forays until Kessler emerged with his prize: ingredient labels affixed to empty cardboard boxes that spelled out the fats, salt and sugar used to make the Southwestern Eggrolls, Boneless Shanghai Wings and other dishes served by the nation's second-largest restaurant chain.
Kessler was on a mission to understand a problem that has vexed him since childhood: why he can't resist certain foods.
His resulting theory, described in his new book, "The End of Overeating," is startling. Foods high in fat, salt and sugar alter the brain's chemistry in ways that compel people to overeat. "Much of the scientific research around overeating has been physiology - what's going on in our body," he said. "The real question is what's going on in our brain."
The ingredient labels gave Kessler information the restaurant chain declined to provide when he asked for it. At the FDA, Kessler pushed through nutrition labels on foods sold through retail outlets but stopped short of requiring the same for restaurants. Yet if suppliers ship across state lines, as suppliers for Chili's do, the ingredients must be printed on the box. That is what led Kessler, one of the nation's leading public health figures, to hang around trash bins across California.
The labels showed the foods were bathed in salt, fat and sugars, beyond what a diner might expect by reading the menu, Kessler said. The ingredient list for Southwestern Eggrolls mentioned salt eight different times; sugars showed up five times. The "egg rolls," which are deep-fried in fat, contain chicken that has been chopped up like meatloaf to give it a "melt in the mouth" quality that also makes it easier to eat quickly. By the time a diner has finished this appetizer, the person has consumed 910 calories, 57 grams of fat and 1,960 milligrams of sodium.
Instead of satisfying hunger, the salt-fat-sugar combination will stimulate that diner's brain to crave more, Kessler said. And the food industry manipulates this neurological response, designing foods to induce people to eat more than they should or even want to, Kessler found.
His theory, borne out in a growing body of scientific research, has implications not just for the increasing number of Americans struggling with obesity but for health providers and policymakers.
"The challenge is how do we explain to America what's going on - how do we break through and help people understand how their brains have been captured?" he said.
Kessler is best remembered for his investigation of the tobacco industry and attempts to place it under federal regulation while he was FDA commissioner from 1990 to 1997.
Kessler's aggressive approach toward the tobacco industry led to billion-dollar settlements between Big Tobacco and 46 states and laid the groundwork for legislation now pending in Congress that would place tobacco under FDA regulation.
Whether government ought to exercise tougher controls over the food industry is going to be the next great debate, especially since much of the advertising is aimed at children, Kessler said.
"The food the industry is selling is much more powerful than we realized," he said. "I used to think I ate to feel full. Now I know, we have the science that shows, we're eating to stimulate ourselves. And so the question is what are we going to do about it?"
Through interviews with scientists, psychologists and food industry insiders, and his own scientific studies and hours spent surreptitiously watching other diners at food courts and restaurants around the country, Kessler said, he finally began to understand why he couldn't control his eating.
"Highly palatable" foods - those containing fat, sugar and salt - stimulate the brain to release dopamine, the neurotransmitter associated with the pleasure center, he found. In time, the brain gets wired so that dopamine pathways light up at the mere suggestion of the food, such as driving past a fast-food restaurant, and the urge to eat the food grows insistent. Once the food is eaten, the brain releases opioids, which bring emotional relief. Together, dopamine and opioids create a pathway that can activate every time a person is reminded about the particular food. This happens regardless of whether the person is hungry.
Not everyone is vulnerable to "conditioned overeating" - Kessler estimates that about 15 percent of the population is not affected and says more research is needed to understand what makes them immune.
But the key to stopping the cycle is to rewire the brain's response to food, he said.
Deprivation only heightens the way the brain values the food, which is why dieting doesn't work, he said.

Unhealthy Foods Hijack Your Brain
Today’ Re-Powering information. I know I tend to keep coming back to the topic of sugar, however it’s one that a lot of people struggle with. Sugar fatigues you, keeps you fat and breaks your body down. I have not tried either of the suggestions that Dr. Mercola recommend, but they both stand to reason as options. If sugar is something you battle, you may consider one of these two options. Read the article and Dr. Mercola’s comments.
When Unhealthy Foods Hijack Your Brain
junk foodsIn a book being published next week, former FDA chief Dr. David Kessler brings to consumers the disturbing conclusion of numerous brain studies -- some people really do have a harder time resisting bad foods.
At issue is how the brain becomes primed by different stimuli. Neuroscientists increasingly report that fat-and-sugar combinations in particular light up the brain's dopamine pathway -- its pleasure-sensing spot. This is the same pathway that conditions people to alcohol or drugs.
The culprits foods are "layered and loaded" with combinations of fat, sugar and salt, and they are often so processed that you don't even have to chew much.
Overeaters must take responsibility, too, and basically retrain their brains to resist the lure, says Kessler.

Dr. Mercola''s Comments
Dr. Mercola's Comments:
Many people can relate to what David Kessler, the former FDA chief, calls “conditioned hypereating” -- a drive to eat sugary, greasy processed foods that has nothing to do with hunger.
It can happen when you walk by a vending machine, drive by one of your favorite restaurants or bakeries, or even when you’re sitting at home watching TV. Suddenly you get a craving for something you know isn’t good for you -- cookies, French fries, ice cream, potato chips, that sort of thing -- and your willpower seems to crumble.
This is an epidemic problem, as in the United States 90 percent of the money Americans spend on food is for processed food, and junk food is available just about everywhere, including in hospitals and schools.
It’s clear that something about these foods is able to wield an incredibly strong force over many of us, to the point that obesity has been named the fastest growing health threat in the United States, and two-thirds of adults are already overweight or obese.
So what is going on here? What about these foods compel people to overeat them at the expense of their waistline, and more importantly their health?
Why It’s So Easy to Be Addicted to Junk Food and Fast Food
Taste, convenience and cost certainly play a role in making junk foods appealing, but there’s more to it than that. The large amounts of sugar, salt and grease in junk foods are clearly addictive.
In one study, rats fed a diet containing 25 percent sugar became anxious when the sugar was removed -- displaying symptoms similar to people going through drug withdrawals, such as chattering teeth and the shakes.
A link was found between opioids, or your brain’s 'pleasure chemicals,' and a craving for sweet, salty and fatty foods. It is thought that high-fat foods stimulate the opioids, as when researchers stimulated rats’ brains with a synthetic version of the natural opioid enkephalin, the rats ate up to six times their normal intake of fat.
Further, long-lasting changes in rats' brain chemistry, similar to those caused by morphine or heroin use, were also noted. According to researchers, this means that even simple exposure to pleasurable foods is enough to change gene expression, which suggests an addiction to the food.
Your Genes Remember When You Eat Sugar
When you eat sugar, not only do your genes turn off controls designed to protect you from heart disease and diabetes, but the impact lasts for two weeks!
Even more concerning, if you eat poorly for a long time your DNA may become permanently altered and the effects could be passed on to your children and grandchildren.
In other words, you are born with a set of genes, but the expression of those genes is not set in stone. Your genes can be either activated or silenced by various factors including your diet and even your mind. It is not your genes that dictate your future health, but rather the expression of those genes that matter.
So in the case of eating sugar, it’s now known that this switches off good genes that protect your body from disease. This is just one of many reasons why you may want to seriously limit or eliminate sugar from your diet.
Sugar is Incredibly Addictive
Another reason we know that people’s love for sugar goes far beyond taste is because of its addictive properties.
Refined sugar is far more addictive than cocaine -- it is one of the most addictive and harmful substances currently known. In fact, an astonishing 94 percent of rats who were allowed to choose between sugar, water and cocaine, chose sugar.
Even rats who were addicted to cocaine quickly switched their preference to sugar, once it was offered as a choice.
The researchers speculate that the sweet receptors (two protein receptors located on your tongue), which evolved in ancestral times when diets were very low in sugar, have not adapted to modern times’ high sugar consumption.
Therefore, the abnormally high stimulation of these receptors by our sugar-rich diets generates excessive reward signals in your brain, which have the potential to override normal self-control mechanisms, and thus lead to addiction.
Your Emotions Play a Major Role, Too
As Kessler said, "Once you know what's driving your behavior, you can put steps into place" to change it.
What this means is whenever you feel the desire to binge on junk foods, it’s necessary that you have a system in place to help curb those cravings.
The system that I personally use and most highly recommend is called the Emotional Freedom Technique (EFT). EFT is a form of psychological acupressure, based on the same energy meridians used in traditional acupuncture to treat physical and emotional ailments for over 5,000 years, but without the invasiveness of needles.
When your body's energy system is disrupted, you are more likely to experience distractions and discomforts related to food, and more likely to engage in emotional eating. Instead, if you engage your body's subtle energy system with EFT, the distracting discomforts like food cravings often subside.
The other major factor that will help you to break an addiction to junk food is tailoring your diet to your nutritional type. Nutritional Typing will teach you which foods you are designed to eat and the ideal proportions of the types of nutrients you require, whether you are a 'Carb', a 'Protein', or a 'Mixed' type.
When you eat the foods that are right for your biochemistry, it will push your body toward its ideal weight and you’ll notice that food cravings largely subside. This is because you’re giving your body the fuel it needs, so you’ll feel satiated throughout the day and be far less tempted by the sugary and greasy foods that once had a hold over you.
End.
Have an uncomfortable day!

Cutting calories 'boosts memory'
Today’s Re-Powering information – It’s obvious that at the end of the day calories matter. I have been preaching about the quality of the calories more than the quantity. If you are going to over eat, I would rather you over eat organic chicken vegetable soup than chicken wings and fried mozzarella sticks. They have a different effect on your body – even if the calories are the same. The natural food is easier to digest, metabolize and does not leave foreign toxins behind. Studies have shown that those who consume fewer calories live longer and have less disease. That stands to reason as over feeding causes inflammation and obesity. It’s also rare that people are over feeding on salad. They are more likely to overfeed on pastries, fried foods and other fast foods which are artery clogging and lead to other diseases such as heart disease and diabetes.
Cutting calories not only leads to fast loss and improved health, a new study shows it also boosts memory so strive to eat for your physiology rather than your emotions or out of habit.
Cutting calories 'boosts memory'
Healthy food
The volunteers had to limit their calorie intake
Reducing what you eat by nearly a third may improve memory, according to German researchers.
They introduced the diet to 50 elderly volunteers, then gave them a memory test three months later.
The study, reported in the Proceedings of the National Academy of Sciences journal, found significant improvements.
However, a dietician said the reduction could harm health unless care was taken.
To our knowledge, the current results provide first experimental evidence in humans that caloric restriction improves memory in the elderly
Munster University researchers
There is growing interest in the potential benefits of calorie restricted diets, after research in animals suggested they might be able to improve lifespan and delay the onset of age-related disease.
However, it is still not certain whether this would be the case in humans - and the levels of "caloric restriction" involved are severe.
The precise mechanism which may deliver these benefits is still being investigated, with theories ranging from a reduction in the production of "free radical" chemicals which can cause damage, to a fall in inflammation which can have the same result.
The researchers from the University of Munster carried out the human study after results in rats suggested that memory could be boosted by a diet containing 30% fewer calories than normal.
The study volunteers, who had an average age of 60, were split into three groups - the first had a balanced diet containing the normal number of calories, the second had a similar diet but with a higher proportion of unsaturated fatty acids, such as those found in olive oil and fish.
The final group were given the calorie restricted diet.
After three months, there was no difference in memory scores in the first two groups, but the 50 in the third group performed better.
Diet warning
They also showed other signs of physical improvement, with decreased levels of insulin and fewer signs of inflammation.
The researchers said that these changes could explain the better memory scores, by keeping brain cells in better health.
They wrote: "To our knowledge, the current results provide first experimental evidence in humans that caloric restriction improves memory in the elderly.
"The present findings may help to develop new prevention and treatment strategies for maintaining cognitive health into old age."
However, care was taken to make sure that the volunteers, despite eating a restricted diet in terms of calories, carried on eating the right amount of vitamins and other nutrients.
Dr Leigh Gibson, from Roehampton University, said that the drop in insulin levels were one plausible reason why mental performance might improve.
The hormone was known to act on parts of the brain related to memory, he said, and the higher levels found in people with poorly controlled type II diabetes had been directly linked to worse memory and cognitive function.
A spokesman for the British Dietetic Association said that people, particularly those already at normal or low weight, should be "extremely careful" about attempting such a diet.
She said: "There is other evidence that, far from enhancing memory, dieting or removing meals can interfere with memory and brain function.
"A drop of 30% in calories is a significant one for someone who is not overweight, and should not be undertaken lightly.
"It could even be dangerous if the person is already underweight."
