Wall Street Journal Reporter Helps Bring Clarity to Thyroid Treatment Controversy


newspaper_reader

On April 11, 2016 an article, Doctors Hear Patients’ Calls for New Approaches to Hypothyroidism, appeared in the Wall Street Journal regarding the growing influence of patient preference on treatment selection for hypothyroidism (sluggish thyroid). The article was written by the WSJ health columnist Melinda Beck. I might have missed it but thanks to a motivated patient I received a copy within a week after its publication.  With a glance I knew this report could be a highly significant addition in the on-going debate between specialists treating hypothyroidism (endocrinologists) and advocates of alternative approaches.

Obesity Related Type 2 Diabetes is More Severe in Teens than Adults


Overweight TeenObesity Related Type 2 Diabetes is More Severe in Teens than Adults

by Gary Pepper, M.D. and Andrew Levine, Pre-Med, Univ of Central Florida

The recently published TODAY study found obesity related type-2 diabetes mellitus (T2DM) is more severe as a teen than as an adult, and high risk of developing diabetes could be tied to weight gain at an early age.

Between 2004 and 2009 the “Treatment Options for Type 2 Diabetes in Youth Study Group” (TODAY) gathered 700 participants who met the American Diabetes Association’s criteria for this disease.  The participants were monitored for between two to six years.  TODAY’s goal was to assess treatment options and the clinical progression of obesity related T2DM in youth.  The mean age of the 700 participants in the TODAY study was thirteen, the majority being female. Sixty percent of the 700 participants were African American or Hispanic, with the remainder being Caucasian. The mean duration of diabetes for the study’s’ participants was less than seven months. A major worrisome finding from the study is a majority of participants were also discovered to have dyslipidemia, an abnormally high amount of fats (cholesterol, triglycerides) in the blood, as well as high blood pressure (hypertension).

Adopted Children Experience Early Sexual Maturity


Puberty occurs when areas within the brain awaken beginning a cascade of hormone signals which conclude with the gonads (ovaries and testicles) increasing their production of the female and male sex hormones estrogen and testosterone. Under the influence of these hormones a child begins the transition from childhood to sexual maturity. In boys puberty is associated with a growth spurt, the appearance of facial, axillary (arm pit) and pubic hair, acne, deepening of the voice, growth of the testicles and penis while girls undergo a growth spurt, develop breasts, acne, pubic and axillary hair, and growth of the clitoris.

Historical data shows the average age of puberty today is many years sooner than in previous generations. Most experts attribute earlier puberty to better nutrition. A recent article in metabolism.com reviewed how “over-nutrition” accelerates obese children into puberty sooner (referred to as precocious puberty) than normal weight children. The latest studies on causes of precocious puberty suggests that a child’s social environment also exerts an important influence on the timing of puberty. Researchers in Madrid publishing in The Journal of Clinical Endocrinology and Metabolism 95:4305 2010 analyzed the age of puberty in normal children, adopted children and children whose families immigrated (children not adopted but subject to high levels of personal stress) to Spain. Adopted children were 25 times more likely than other groups of children to undergo precocious puberty (breast development before the age of 8 years in girls, and boys under 9 years of age with testicular growth). Over-all girls were 11 times more likely than boys to demonstrate precocious puberty.

Researchers speculate that socio-emotional stresses early in life of children who are later adopted result in changes in the brain that cause premature maturation of vital nerve pathways. This early brain maturation later results in stimulation of the pituitary gland, turning on the hormone pathways that cause puberty. This seems strange to me because various forms of deprivation in childhood can also delay puberty. For example, girls who have anorexia remain child-like in their body development and may fail to menstruate even into their late teens. A decade ago I studied hormone levels in adults during the stress of illness and surgery and found this lowered the sex hormone levels in their blood. This makes sense from an evolutionary point of view because during stressful conditions nature wisely cuts off the reproductive hormones. Why make babies if the environment is hostile in some way? Why the opposite occurs in children under stress of adoption is an interesting but unanswered question.

Changes in Hormones After Gastric By-Pass Speed Weight Loss and Lower Blood Sugar


It seems obvious that cutting away part of the stomach and intestine should cause weight loss. With a smaller stomach and less intestine fewer calories can be absorbed per day causing weight loss. Surgeons who perform gastric by-pass were puzzled however, by how fast their patients showed metabolic improvement after undergoing this procedure. They noticed many of their diabetic patients could be taken off diabetic medication immediately after surgery before weight had been lost. Scientists looking into this phenomena discovered unsuspected ways gastric by-pass improved metabolism.

The intestines produce hormones which regulate blood sugar and appetite. GLP-1 is among the best known of these intestinal hormones. GLP-1 is the basis of a whole new generation of medications used to treat diabetes such as Byetta, Victoza, Januvia and Onglyza. GLP-1 lowers blood sugar, stimulates the pancreas and reduces appetite. After gastric by-pass increased amounts of GLP-1 are produced by the remaining intestine. In a study published in the Journal of Clinical Endocrinology and Metabolism (95:4072-4076, 2010), researchers at St. Luke’s Hospital in New York discovered that levels of oxyntomodulin, another intestinal hormone that suppresses appetite and acts like GLP-1 on blood sugar levels, is doubled after gastric by-pass.

These exciting discoveries help explain why obese diabetics can often be sent home without any medication to control blood sugar immediately after undergoing gastric by-pass surgery. Although most insurance plans do not cover gastric by-pass surgery, dramatic improvements in patients after the procedure with greatly reduced medication costs may convince insurance companies that paying for the procedure will result in better outcomes and save them money in the long run.

Growth Hormone Deficiency Tied to Obesity and Accelerated Aging in Young Adults


Due to the potential for abuse and high cost, growth hormone treatment in adults is the subject of much controversy. I believe that treating adults with growth hormone deficiency is many times an appropriate and beneficial choice. Firming up my conviction for treating adult growth hormone deficiency is a recent study conducted in the Netherlands and UK published in the Journal of Endocrinology and Metabolism (JCEM 95:3664-3674, 2010). The researchers compared Body Mass Index (BMI), waist circumference, triglycerides, and HDL (good cholesterol), between normal adults and those with low growth hormone levels due to deficient pituitary function (hypopituitarism). All measurements of obesity and lipid metabolism were significantly worse in the young adults (younger than 57 years) with growth hormone deficiency compared to normal adults of a similar age.

As I pointed out in previous articles at metabolism.com, growth hormone levels naturally decline as we get older. The authors of the present study note that growth hormone levels decline 14% per decade in adults. I conceive of this as one of the ways nature gets rid of us after we complete our biological/reproductive functions, since without growth hormone our muscles, immune and nervous systems, decline, leading to death. It’s planned obsolescence… what is typically referred to as aging. In the recent study senior citizens have equivalent levels of obesity and abnormal lipid metabolism as young adults with growth hormone deficiency. The authors note the effect on the body of growth hormone deficiency in young adults is equivalent to 40 years of aging. The theory that growth hormone functions to preserve our tissues during youth and aging results from its absence, appears confirmed by these results.

Most normal young adults aren’t growth hormone deficient and the population that would qualify for growth hormone treatment from this group is small. What about older adults with low growth hormone who are troubled by the “natural” decline in their body function? Should or could we treat this much larger population with growth hormone? It is my experience that private and federal insurers will not pay for this treatment regarded as “cosmetic”. On the other hand, there will be physicians who will comply with a request for growth hormone treatment from individuals who possess enough cash and motivation. Less affluent or determined individuals will have to contend with natural aging just as our ancestors have done for thousands of years.

Chubby Neck Becomes the New Normal


After reading the latest research on the metabolic hazards associated with chubby necks I am more sensitive to the size of people’s necks then ever. Of course I look at the size of my patient’s neck but people who I pass in the street or supermarket may find me staring. Watching TV a few days ago I was startled by a series of people in one commercial for Quicken Loans who definitely qualify for the metabolic high risk category based on neck chubbiness. One after another the characters in this commercial walk on, outdoing each other in this physical trait. Has the chubby neck become the new normal? If so, the incidence of diabetes and heart disease is sure to continue to rise.

Let me know if you agree with my impression, or am I biased by being an endocrinologist?

Large Neck Size Equals Big Metabolic Problems


Large Neck Size Equals Big Metabolic Problems:

A bulging stomach is widely accepted as a sign of poor metabolic health. A recent study published in the August Clinical Endocrinology and Metabolism (95:3701, 2010), finds a chubby neck is likely to hold even a worse prognosis for metabolic health.

The research team evaluated the relationship between waist circumference and neck circumference with levels of blood sugar, good cholesterol (HDL), bad cholesterol (LDL), triglycerides, and insulin resistance, as well as blood pressure. What was found was that neck circumference was a better predictor than waist circumference of elevated blood pressure, LDL, triglycerides and insulin resistance, with lower levels of HDL. All this amounts to a greater risk of cardiovascular disease as neck size increases. As an example, an increase in neck circumference of about one inch is expected to result in a 2.5 point rise in blood pressure.

The authors point out that the neck circumference was a more accurate predictor of cardiovascular risk in women than men. The average neck size for men in this study was about 16 inches (40.5 cm) and about 13.7 inches for women (34 cm).

Alfred Hitchcock, the famous director of suspense movies, made a trademark of his corpulent silhouette with bulging chin and abdomen. Thanks to this research we know his silhouette can signify more than a movie that will thrill you but also a metabolism that will kill you.

Spirulina and other Green Superfoods Can Jumpstart Good Health by Tom Hines


Metabolism.com is pleased to share the following article provided by our guest contributor, Tom Hines.
**********************************************************

In some ways, your body is like a machine — it works best when it’s properly maintained and tuned up. Food is your fuel and when you fill your tank with lousy fuel, your engine sputters and stalls. If your body’s engine is sluggish and needs a jumpstart, spirulina and other green superfoods can help deliver the energy necessary to keep the machine running smoothly, avoiding a breakdown.

Spirulina is a ‘green superfood,’ a term used to describe various nutrient-rich natural supplements, which include Chlorella, Wheat Grass, Barley Grass, Alfalfa and Kelp. Unlike most store-bought supplements, the concentrated vitamins and minerals they provide are not synthetic. Green superfoods are whole foods harvested directly from nature and are exactly what your body needs to offset stress and to clear away toxins.

SAD is very sad indeed

S.A.D. stands for Standard American Diet – there was never a more apt acronym. The majority of U.S. citizens today subsist on processed fast food laden with refined carbohydrates and saturated fats. Meats are frequently tainted with growth hormones, antibiotics and pathogens. For people who manage to work the recommended five to nine daily servings of fruit and vegetables into their diet, modern agricultural techniques have stripped crops of many vitamins and minerals.

Processed and cooked foods, which are the cornerstones of the S.A.D, and beverages such as coffee, tea, soft drinks and alcohol create an acidic blood pH, encouraging the growth of bacteria, fungus and mold. In an overly acidic environment, the body literally begins to compost. Illnesses such as heart disease and diabetes are often the result of the composting process. Green superfoods have an alkalizing effect, counteracting the acidity caused by poor diet, stress and toxic overload and setting the stage for a return to good health.

Spirulina and Chlorella, the most super of the green superfoods

Spirulina is a blue-green algae whose name comes from its spiral coil shape. High quality spirulina thrives in both salt and fresh water in tropical climates and it is known to have nourished the Aztecs, who harvested the algae from Lake Texcoco. Some of the benefits of Spirulina are:

  • Contains all of the essential amino acids vital to human health
  • An excellent protein source for all vegetarians, including vegans
  • Balances blood sugar by boosting glycogen, which offsets insulin
  • Rich in GLA (gamma linolenic acid) and other essential fatty acids Delivers an array of vitamins, including the all-important folic acid
  • High in potassium and a dozen other minerals
  • Improves focus and mental clarity

Chlorella is a single-celled green algae whose name is derived from Greek and Latin words that translate to “little green.” In the 1940’s and 1950’s, intensive research was done on little green algae’s potential role in solving world hunger, due to its high protein content and its bounty of beneficial vitamins and minerals. The natural health community, meanwhile, has always touted Chlorella’s health-imparting properties, particularly in the area of detoxification. In addition to being the very best source of chlorophyll, here are some more of Chlorella supplement benefits:

  • Rids the body of toxins and stored waste
  • Tones and cleanses the blood
  • Reduces body odor, acting as an internal deodorant
  • Improves bowel health and reduces flatulence
  • Naturally freshens the breath
  • Clears the skin

Cereal grasses and seaweed

Wheat grass is a popular juicing ingredient due to its superior nutrition, which it delivers without raising blood sugar. It also helps to lower blood pressure.

Barley grass alkalizes the blood and strengthens the digestive system.

Alfalfa helps reduce LDL (low-density lipoprotein) or bad cholesterol, without affecting levels of HDL (high-density lipoprotein) or good cholesterol and studies are underway to determine its effectiveness at lowering blood sugar levels and its ability to invigorate the immune system.

Kelp is a brown-algae seaweed, which grows in abundant kelp forests in shallow oceans all around the world. Kelp is rich in iodine and therefore beneficial to overall thyroid health. Its high vitamin and mineral content promotes pituitary and adrenal gland health as well. It’s renowned for its contribution to lustrous hair and skin. Taken shortly after exposure, it can also mitigate the negative ramifications of heavy metals and irradiation.

Making the most of green superfoods

Incorporating Spirulina, Chlorella and other green superfoods into the diet is easy, since they are all available in powdered form. Simply mix the desired amount into salad dressing, or add it to soup, juice or water. The taste is fresh and green and the active enzymes of living food add a healthy dimension even to a less than healthy meal. Of course, pregnant or breastfeeding women and people taking medications should consult with their doctors before incorporating any new food into their diets.

Many people who regularly incorporate green superfoods into their daily regimen have reported increased energy, mental clarity and an overall healthy glow. When stress, toxic thoughts and an imperfect diet have left your body’s engine sluggish, green superfoods are a quick and easy way to put yourself back on the road to health. Long may you run!

The Joy of Being Vegetarian; by Louise Infante


A member of metabolism.com, Louise Infante, is a great enthusiast of the vegetarian life style. Louise submitted this blog to metabolism.com so we could help her get the word out. I found the article extremely informative and hope you do too. Thanks Louise for your effort.

Here is what Louise has to say:

*********************************************************

Give me five minutes and I’ll give you 1 very good reason for being vegetarian.

While fish is the most important dietary way to obtain the long-chain omega-3s eicosapentaenoic acid and docosahexaenoic acid, which has been shown to be essential in supporting brain health, low intake of eicosapentaenoic acid and docosahexaenoic acid in vegetarians does not adversely affect mood, reported by a new study (Nutr J. 2010;9:26. DOI:10.1186/1475-2891-9-26).

A research team from Arizona State University conducted a cross-sectional study to compare the mood of vegetarians who never eat fish with the mood of healthy omnivorous adults.

An overall total of 138 healthy Seventh Day Adventist adults residing in Arizona and California (64 vegetarians and 79 non-vegetarians) were enrolled in the study and completed a health history questionnaire, food frequency questionnaire and 2 psychometric tests, the Depression Anxiety Stress Scale and also the Profile of Mood States..

Vegetarians had significantly lower mean intakes of eicosapentaenoic acid, docosahexaenoic acid and the omega-6 arachidonic acid; they had higher intakes of the omega-3 alpha-linolenic acid and the omega-6 linoleic acid.

“Seed oils are the richest sources of α-linolenic acid, notably those of rapeseed (canola), soybeans, walnuts, flaxseed (Linseed oil), clary sage seeds, perilla, chia, and hemp.”

However, the vegetarians also reported significantly less negative emotion than omnivores in both psychometric tests. Mean total psychometric scores were positively linked to the mean intakes of eicosapentaenoic acid, docosahexaenoic acid and arachidonic acid , and inversely related to alpha-linolenic acid and linolenic acid intake.

The study team noted there is also the possibility that vegetarians may make better dietary choices and could generally be healthier and happier.

If you want to give it a try, here is an example of vegetarian recipe based on Italian cuisine

Italian Spaghetti with Zucchini

Ingredients:
* 17 oz. Spaghetti
* 24 oz. Of thin sliced zucchini
* 1 / 2 cup walnuts oil
* A few basil leaves
* 2 tablespoons of yeast flakes
* Salt and pepper

In a skillet or frying pan heat the oil and when hot, add garlic and zucchini. Raise heat and stir often to complete their cooking. They need to be golden and crispy outside and tender inside. Cook the pasta, drain and sauté in pan with zucchini, basil and yeast. Serve immediately.

Zucchini contain fewer calories and possess no fat. But they are a good source of potassium, e vitamin, ascorbic acid, folate, lutein and zeaxanthin.

These types of nutrients are extremely sensitive to heat and to enjoy their benefits you should find a quick solution to cook or even eat raw in salads.

From the therapeutic perspective, zucchini have laxative, refreshing, anti-inflammatory, diuretic and detoxifying action.

Does Inflammation Caused by Obesity Result in Diabetes ?


What comes to mind when considering the term “inflammation”? A festering pimple, or perhaps a high fever, an infected tooth, toe, abscess? These are typical examples of inflammation. Inflammation may exist in many other forms however, including possibly obesity.

Inflammation describes the immune system when it is activated. The presence of pus or fever are obvious forms of this. More subtle forms of inflammation can exist in the body. Recently, researchers from Australia, presented evidence that obesity itself is associated with abnormal activation of the immune system, or in other words, inflammation. This inflammation might in turn, cause type 2 diabetes. It is already becoming clear that the inflammation associated with obesity contributes to insulin resistance, the first step in the development of type 2 diabetes. In a study just published in the June volume of the Journal of Clinical Endocrinology and Metabolism (95:2845-2850, 2010), patients with either type 2 diabetes or pre-diabetes were evaluated for the distribution of inflammatory blood cells before and after gastric band surgery. Abnormal immune activation or inflammation was detected in this group. After an average of 13% weight loss following gastric surgery, the scientists found up to an 80% reduction in inflammatory blood cells. Many of the patients were able to significantly reduce their diabetic medications after the weight loss. The conclusion is that inflammation may result from obesity and is reversible when significant weight is lost. Metabolic problems like diabetes improve as the inflammation is reduced, as well. Therefore, inflammation may be part of the reason people develop diabetes as their weight increases.

Studies like this will provide new avenues for attacking the development of type 2 diabetes due to excessive weight gain, and possibly to help find ways of combating obesity, as well.
