Skipping breakfast because you think that one less meal through the day will help you lose weight? Well, you may want to rethink that. The medical literature reports that roughly 10%-20% of Americans routinely skip breakfast whether for weight management or out of convenience.
A new report on a randomized trial finds that skipping breakfast can trigger a condition referred to as insulin resistance. It was found that skipping breakfast triggered acute
insulin resistance and elevated levels of free fatty acids in nine
obese, non-diabetic women, compared with a day on which they ate
breakfast.
Insulin is a hormone that is produced in the pancreas and released in the blood stream in response to sugars in the blood (glucose). Glucose is obtained from nearly all the food we eat and serves as the fuel to produce energy for every tissue of the body. The insulin is necessary for the glucose in the blood to enter the tissues, sort of like a key in a lock. When the body develops resistance to insulin the body is then forced to dump more insulin into the blood stream in an attempt to "open up the tissues". Ironically this excess insulin release tends to make the tissues even more resistant, and the cycle repeats itself over and over with each skipped breakfast. The situation is not much better with a breakfast that is high in refined carbohydrates (ie, breakfast cereals) and low in proteins.
Insulin resistance is the forerunner of type 2 diabetes and a component of the disorder metabolic syndrome. Elevated insulin levels in the blood have also been linked to a number of other health compromising conditions.
On the days of skipped breakfast indirect calorimetry measures showed
decreased energy expenditure (difficulty burning calories) and a significantly
reduced respiratory quotient (a measurement of basal metabolic rate), which indicates greater fat oxidation (LDL cholesterol production).
Just 1 day of missing breakfast
could do this. It is easy to see how skipping breakfast regularly over time may lead to
further metabolic problems such as chronic insulin resistance and
possible progression to type 2 diabetes.
It seems breakfast is an important meal of the day, maybe more so than originally thought. It is important to eat a balanced breakfast containing a significant amount of quality protein such as eggs or yogurt.
For your better health,

Another Good Reason To Avoid Refined Carbohydrates
When watching our weight we can often joke about being "addicted" to sweets, cakes and pastries. It turns out, that comment may not be as far from the truth as you may have thought.
A new study published in the American Journal of Clinical Nutrition and reported in Medscape.com finds that the consumption of refined carbohydrates increases the blood flow to the area of the brain that relates to addictions and can literally alter the activity of the brain.
This also helps explain why fast food and soft drink industry finds the addition of sugar to their products so profitable.
A new study published in the American Journal of Clinical Nutrition and reported in Medscape.com finds that the consumption of refined carbohydrates increases the blood flow to the area of the brain that relates to addictions and can literally alter the activity of the brain.
This also helps explain why fast food and soft drink industry finds the addition of sugar to their products so profitable.
Consumption of a meal that has a high glycemic
index (GI) appears to stimulate key brain regions related to craving and
reward, a finding that supports the controversial hypothesis of food
addiction, new research suggests.
Investigators from Boston Children's Hospital in Massachusetts found that compared with consumption of a low-GI meal, a meal high in refined carbohydrates decreased plasma glucose, increased hunger, and selectively stimulated brain regions 4 hours after eating — a critical time point that influences eating behavior at the next meal.
"We think we have shown for the first time that refined carbohydrates' biological effects can provoke, independent of calories and tastiness, symptoms related to addiction in susceptible people — those who are overweight or obese," said the study's principal investigator, David Ludwig, MD, from Boston Children's Hospital.
Dr. Ludwig, director of the hospital's New Balance Foundation Obesity Prevention Center, told Medscape Medical News that his team's preliminary findings support "the notion of food addiction [which] is very controversial because, unlike drugs of addiction, we have to eat to survive."
Craving Carbs
He said the randomized, blinded, crossover study in 12 overweight or obese men had several strengths over previous studies whose findings also suggested that certain tasty foods might be addictive.
"Prior studies, best described as observational, tended to compare vastly different foods, such as cheesecake and boiled vegetables," he said.
In the new study, participants aged 18 to 35 years consumed, in a randomized order on test days 2 to 8 weeks apart, 2 test milkshakes that had similar ingredients, calories (500 kcal), appearance, taste, and smell.
Participants were not aware which was the low-GI meal (37%) with slow-acting carbohydrate and which was the high-GI meal (84%) with fast-acting carbohydrate, and they reported no preference for either meal.
Additionally, the investigators monitored participants 4 hours after the meal, when the individuals likely would be considering what to eat at their next meal. At that time, participants underwent a final blood glucose test and neuroimaging, and rated their hunger levels.
After eating the high-GI meal, participants initially had a surge in blood glucose level that was 2.4-fold higher than after the low-GI meal, followed by a crash in blood glucose at 4 hours, the authors reported. They also reported excessive hunger 4 hours after the high-GI meal, Dr. Ludwig said.
The investigators looked directly at participants' cerebral blood flow, as a measure of resting brain activity, using arterial spin labeling functional magnetic resonance imaging (fMRI), which allowed them to examine persistent effects of test meals.
"Every single subject showed intense activation in the nucleus accumbens, the area of the brain related to addiction," he said.
The results show that highly processed carbohydrates, such as white bread, potatoes, and concentrated sugar, "alter brain activity in ways that make us crave them even more," he said.
Clear Take-Home Message
Dr. Ludwig stated that the study must be repeated in larger numbers of persons, in a more diverse population, and before and after weight gain. Yet he said that the initial results send a clear take-home message: "Avoiding highly processed carbohydrates could help overweight people avoid overeating."
Mark Gold, MD, a longtime researcher in the area of food and addiction, from the McKnight Brain Institute of the University of Florida (UF), Gainesville, said it is important that clinical research tests the food addiction hypothesis first generated by laboratory researchers.
Asked by Medscape Medical News to comment on the findings, Dr. Gold, who was not involved with the study, said that the brain imaging test the researchers used "is exceptional and provides additional strong evidence that manufactured foods, sugar, and fats can interact with the brain and systems that [also] are hijacked by drugs of abuse."
"Hedonic overeating...makes more sense with clinical research like this," Dr. Gold, who is professor and chair of psychiatry at UF College of Medicine, concluded.
This study was funded by the National Institutes of Health and the National Center for Research Resources, Bethesda, Maryland; the Pediatric Endocrine Society, McLean, Virginia; the Endocrine Fellows Foundation, Washington, DC; and the New Balance Foundation, Boston, Massachusetts. Dr. Ludwig and Dr. Gold have reported no relevant financial relationships.

Controlling Blood Sugar Without Drugs
If you or a family member or friend have difficulty controlling blood sugars and aren't thrilled about the prospect of a lifetime on glucose reduction meds here is an article from natural news with some great recommendations.
(NaturalNews) Nearly one-third of all Americans today are either diabetic or pre-diabetic, which basically means their bodies have lost the ability to properly process sugar. As a result, excess sugar molecules, typically from junk foods, accumulate in the blood and vital organs leading to chronic illness and eventually premature death. But if you are one of the millions of people that struggles with blood sugar issues, or even full-blown diabetes, you do not have to go the pharmaceutical drug route to find relief or a cure.
Like most other types of chronic illness, diabetes and pre-diabetes are more often than not the direct result of poor diet, stress, lack of exercise, and nutrient deficiency. Almost all chronic disease, in fact, is the long-term consequence of one or more of these dietary and lifestyle failures, which means correcting them also has the potential to fully cure disease, in many cases. Here are some helpful tips for overcoming your blood sugar woes, which in turn may help eradicate disease and restore your health:

1) Cut out the sugar, grains, and omega-6 fatty acids. The standard American diet, commonly referred to as "SAD," is jam-packed with simple carbohydrates like refined sugar, processed flour, and vegetables oil, all of which spike insulin levels and cause inflammation. Carbohydrates in general are toxic to the body, particularly when not enough energy is being expended, as whatever carbohydrates are not used are sugar.
"Any form of carbohydrate is eventually broken down by the body into glucose, a simple form of sugar," explains the Wellness Mama blog. "While the body can use glucose for fuel, levels that exceed what is needed are toxic to the body ... when the body senses glucose in the bloodstream, the pancreas releases a hormone called insulin to signal the body to store the glucose as glycogen."
Once the body's glycogen receptors become "full," however, glucose continues to cycle through the body's bloodstream, triggering the production of even more insulin. Not only does all this excess insulin damage the glycogen receptors, but it also ends up overburdening the pancreas, which of course produces insulin, and storing the excess glucose as fat inside the body. Carbohydrates, in other words, are primarily responsible for making people fat, and not actually fat itself.
So rather than continue gorging on corn chips, cookies, snack crackers, breads, and other heavy-carbohydrate foods, switch to low-carbohydrate, nutrient-dense foods like grass-fed meat and butter, pastured eggs, fruits and vegetables, nuts and seeds, and raw, full-fat dairy products. As long as you are not allergic to any of these foods, you should be able to get your blood sugar and insulin levels under control, and avoid creating a toxic environment within your body where disease is able to thrive.
2) Reduce stress levels and recharge your adrenal glands. For many people, excess stress leads to the production of too many stress hormones, which can severely damage the endocrine system. And when the endocrine system is out of whack, and hormones are not being produced and regulated as they should, the body loses its ability to properly metabolize nutrients, including sugar. The end result, of course, is a propensity for high blood sugar and eventually diabetes.
"When stress occurs, whatever the source, the hypothalamus signals the adrenals to release cortisol (and adrenaline)," adds Wellness Mama. "Excess cortisol can contribute to hormone imbalance in the body since the body uses hormones like progesterone to manufacture cortisol. Excess cortisol ... can also interfere with the body's ability to regulate blood sugar, reduce fat burning ability, raise insulin, suppress thyroid function and cause gain in belly fat."
To avoid over-stressing your body, be sure to get plenty of rest every night, preferably going to bed before 10:30pm in order to allow your adrenal glands a chance to "recharge." You can also de-stress nutritionally by mixing one inch of fresh, minced ginger together with a one-half teaspoon of ground black seeds, also known as black cumin (Nigella sativa), and eating it. This natural remedy is just one example of a practical way you can promote relaxation.
3) Exercise regularly, repair your gut, and eat plenty of "good" fats. One of the most effective ways to remedy insulin resistance is simply to engage in more physical activity. Exercise, it turns out, has been
