From one of our readers: I’ve searched the web but found nothing that tells me how to
distinguish if my metabolism is healthy. I’ve found plenty of
ways to tell me how to improve my metabolism but nothing
that explains what is normal. Are there outward signs that
will tell you if your metabolism is healthy?
According to Webster’s Dictionary, metabolism is defined as a chemical and physical processes continuously going on in living organisms, But when most people think about metabolism they focus on one specific process , the process that releases and stores energy from the food we eat. This is because this type of metabolism not only affects how efficiently your body burns fuel but also influences how easily our bodies gain or lose weight.
Turning Food into Energy
In simple terms, your metabolism is the rate at which your body breaks down nutrients from the foods you eat and converts them into a form the body can use. After you’ve eaten a bowl of cereal or a sandwich, chemicals produced in the digestive tract, known as enzymes, break down all of the complex molecules that make up the food into smaller, more usable nutrients. Proteins are broken down into amino acids, fats into fatty acids, and carbohydrates into simple sugars like glucose. These nutrients are then absorbed into the blood where they are transported all over the body.
At this point the nutrients can be used in different processes. Amino acids are usually used to build and repair tissues, while glucose enters cells and is metabolized for energy. Any extra nutrients left over after these processes are generally stored in body tissues, especially the liver, muscles and body fat, and used for energy at a later date if the body needs it. (Think of it like a squirrel stocking up nuts for the winter.)
In this way, the process of metabolism really is a balancing act between two very different types of activities: (1) building up body tissues and energy stores, and (2) breaking down energy-rich nutrients, body tissues and energy stores to produce fuel that will power the body.
Anabolism, or constructive metabolism, focuses on building tissues and storing energy. During this process, small molecules are converted into larger, more complex molecules. For example, small molecules of glucose become larger, more complex storage molecules called glycogen. Amino acids are organized into proteins. And fatty acids are combined to create dreaded fat molecules. Anabolism is a very important process in the body, as it supports the growth and repair of cells and tissues and helps the body store energy so it can be used sometime in the future.
On the other hand, catabolism, or destructive metabolism, breaks down large molecules (mostly carbohydrates and fats) to release energy. We mostly refer to this energy burning as metabolism, even though this is not the only type of metabolism. This is the process that fuels all of the activity in our cells and keeps our body running. It also provides the energy needed for anabolic, energy-storing processes, helps heat the body and enables our muscles to contract so we can move.
The Importance of Hormones
Hormones are chemical substances in the body that control and regulate the activity of certain cells or organs, as well as specific chemical and physical processes. Several important hormones are involved in controlling the rate and direction of metabolism:………..

Mainstream endocrinologists seem to be moving grudgingly toward acceptance of combination T4 plus T3 therapy for hypothyroidism. A great example of the mixed feelings harbored by endocrinologists in this regard is the title of a recent editorial, â€œ Combo (treatment) a Last Resort for Hypothyroidismâ€ . Although the author, Dr. Bruce Jancin of the University of Colorado, recognized the value of combination T4 plus T3 therapy, he did so with the least possible enthusiasm. In his article the doctor acknowledged the weakness of scientific studies showing negative results with combination therapy and pointed out the findings of the Watts Study which provides a genetic rationale for why some people need to have T3 added to T4 to return to proper thyroid hormone balance.

Understanding of the various ways vitamin D effects the body is growing rapidly. Originally this vitamin was thought to only effect calcium in the blood and bone but recent research shows it possesses important influences on the immune system and cancer development. A study just published in Journal of Endocrinology and Metabolism June 2012 now shows that this same vitamin can possibly influence metabolism. A common disorder of metabolism known as Syndrome X or the Metabolic Syndrome is characterized by high triglycerides and low good cholesterol (HDL), abdominal obesity, along with elevated blood pressure and blood sugar. The researchers discovered those with vitamin D levels between 16 and 20 were 75% more likely to develop the Metabolic Syndrome within 5 years than those with vitamin D levels above 34 (levels below 30 are considered low).
Whether low vitamin D is the cause of the Metabolic Syndrome is unclear. Vitamin D prevents fat cells from reproducing, helps the natural process of triglyceride breakdown and helps regulate blood sugar by making insulin work more efficiently. Without enough vitamin D the fat cells could multiply faster, triglyceride levels accumulate and blood sugar rise as is seen in Metabolic Syndrome.
As I have explained in previous posts at metabolism.com, vitamin D is also related to development of hardening of the arteries (atherosclerosis) and obesity in Type 2 Diabetes which could be considered a more advanced form of Metabolic Syndrome.
Doctorsâ€™ efforts to monitor vitamin D levels are being hindered by new regulations by Medicare and private insurance carriers to deny payment for vitamin D screening. Lately, a number of my patientsâ€™ vitamin D tests were denied by insurance carriers with patients being charged over $200 per test because it was not â€œindicatedâ€.
Recommendations for vitamin D supplementation are debated. When skin is exposed to sunlight it manufactures vitamin D so there is thought that people who get sun exposure should not need vitamin D supplement but that is not borne out in reality. Previously the recommended daily allowance (RDA) was 400 units per day an amount which has been increased slightly for the elderly. Some experts recommend 1000 unit daily or more. In my practice I generally recommend starting at 1000 units and then rechecking 25 hydroxy vitamin D levels a few months later. Some individuals require 4000 unit or more daily to achieve vitamin D levels over 30. When purchasing vitamin D the D3 form appears to be converted in the body more rapidly than the D2 variety. High priced brands of vitamin D, in my opinion, are a waste of money.
Much as has been said recently about the health benefits of coconut milk and coconut oil. Coconut milk is a white liquid mixture of water and the white â€œfleshâ€ of the coconut and is considered a more diluted form of coconut oil a thick clear liquid. Coconut extracts have been used in commercial food products, non-dairy creamers and cooking for many years but lately there has been a burst of publicity for coconut oil and milk as a new form of health-food with beneficial properties including increasing energy, preventing cancer and speeding weight loss. I have seen it being added to ice cream and even bottled water. I want to sound a note of warning here.
Most physicians and nutritionists will advise against having too much fat in the diet for a number of reasons. First, and most obvious, fats have lots of calories. In addition dietary fat can increase the bad cholesterol (LDL) content of the blood leading to increased risk of heart attack and stroke. Among the different kinds of fat that raise LDL the worst are the saturated fats. One tablespoon of coconut oil contains about 120 calories with about 90% of the coconut oil being saturated fat. In fact the saturated fat, palmitic acid, takes its name from the plant that produces coconuts, the palm tree. Compare this to the fat in dark chocolate which is 30% oleic acid, the healthy monounsaturated fat found in olive oil.
Oils which are far more beneficial for preparing foods are unsaturated fats including the monounsaturated and polyunsaturated fats. I like canola, safflower and olive oil due to their high content of these healthier fats.
Coconut oil has many other applications which are useful outside the body. It can be used as a diesel fuel, deodorant, insect repellent, to make soap, and as a moisturizer for hair and skin. My advice is to think twice however, before supplementing your diet with it.
In part one of this series we looked at the cause of polycystic ovarian syndrome (PCOS) and the many complications it causes. Weight gain, acne, excess hair growth on the face and body, high cholesterol and high blood sugar due to insulin resistance are among the problems associated with PCOS. One particular area of concern for PCOS sufferers is infertility due to lack of ovulation. PCOS is the cause of anovulatory infertility in 3 out of 4 cases. Before the acceptance of medical therapy for infertility due to PCOS a surgical approach referred to as a wedge resection of the ovary was performed which allowed patients with PCOS to ovulate and conceive normally. Low success rates with this procedure, complications of surgery and improved medical therapies have all resulted in the end of this type of treatment in most situations. At present, treatment of infertility associated with PCOS generally consists of using a drug to combat insulin resistance known as metformin often in combination with the fertility drug clomid, which has a high rate of success.
Treatment of the excess hair growth associated with PCOS often consists of using the drug spironalactone and the use of birth control pills. Spironalactone is a very interesting drug used for decades as a salt depleting diuretic but also has an effect to block the action of the male hormone testosterone. The action of spironalactone to block testosterone was discovered when it was noticed that men using this diuretic developed tender nipples and breast enlargement (gynecomastia). Oral contraceptive agents are also useful to combat hirsutism because these agents also cause reduce testosterone levels by putting the ovary in a dormant “resting” state. Cosmetic procedures are always another option to treat unwanted hair growth. Laser hair removal appears to be replacing the older modality of electrolysis for this purpose.
Can PCOS be cured? Once PCOS develops it can be controlled but not cured unless the ovaries are removed. At menopause PCOS-related problems diminish as the ovary stops making sex hormones including testosterone which is one of the culprits during the reproductive years. A recent study published this year in the journal Pediatric Endocrinology showed that using metformin treatment in pre-adolescent girls thought to be at risk for PCOS reduces the risk and/or the severity of PCOS in later years. It may do this by blocking fat accumulation in the abdomen and liver which seems to set off the insulin resistance. Metformin is not FDA approved for this purpose and as a generic drug there is little profit potential in developing this treatment. I expect it will be many years before preventive therapy for PCOS will come before the FDA for approval .
This information is strictly for educational purposes. Due to high risk of toxicity of medical therapy in young women who can potentially become fertile under treatment for PCOS, no drug should be taken without the close supervision of a physician.

The mission of the The Thyroid Project is to encourage sharing of information and experience between the public and the medical community about the treatment of hypothyroidism (low thyroid function). For at least the past few decades there is a growing awareness of â€œsomething missingâ€ in the way suffers of hypothyroidism are treated for their disease.
Too many patients, as documented in an on-line study of 12,000 individuals conducted by the American Thyroid Association published in June 2018, (https://doi.org/10.1089/thy.2017.0681) , complain of persistent symptoms of hypothyroidism despite what their doctors believe is successful treatment with levothyroxine (brands include Synthroid, Unithroid, Tirosent, Levoxl). We believe something needs to be done to resolve this conflict between patients and their doctors.
Without effective intervention the early stage of type 2 diabetes known as prediabetes carries a high risk of progressing to outright diabetes. Metabolism.com provides an up-to-date summary of recommendations from national authorities, for preventing and possibly reversing this life long affliction
Diabetes can be defined simply as elevated blood sugar levels. What exactly is high blood sugar and when should someone be concerned about their level? Does having prediabetes mean diabetes is around the corner? Metabolism.com tackles this tricky but important topic in this comprehensive review.
By Gary M. Pepper, M.D. Ozempic, Rybelsus, Trulicity, Wegovy, Saxenda are the central players in the weight loss craze sweeping across the globe. Metabolisim.com has been monitoring this phenomenon from its beginnings in 2008 with its report “Lizard Spit Reduces Blood Sugar and Appetite”, regarding the first drug in this class, Byetta (exenatide). Caught In the middle of the current chaos are the medical experts who treat diabetes and have been prescribing these medications for more than a decade. Here is a brief commentary from one such board certified endocrinologist; “I started treating Type 2 diabetics with GLP-1 agonists more than 10 years ago. In some respects, these medications have revolutionized the treatment of diabetes by lowering blood sugar effectively and promoting weight loss at the same time, a unique combination of benefits. Not everyone benefits from these drugs to the same degree unfortunately, and I have seen lots of patients experience unacceptable side effects from them. Nothing though, has prepared me for what is happening now. Too often, I find myself confronting someone who expects me to prescribe one of these drugs just so they can lose weight. Sadly, one extreme example was someone who, despite battling a life threatening medical condition, was insistent on getting a prescription. At the same time my diabetic patients are scrambling to find a place to buy their medications if they can even afford it. It is disheartening, to say the least, and I dread the negative interactions with some of my patients I now face almost daily.”
Off- Label Use
The FDA is the U.S. government’s department tasked with evaluating and approving drugs for specific medical conditions. When a new medication is approved for treating a medical condition by the FDA the agency will, at the same time, set strict guidelines for exactly which patients may use the newly approved drug. When a medication is used “off-label” it means that these limitations are being overridden by the provider for a potential benefit which outweighs the drugs risks. It is a general misconception that off-label means illegal; it does not. This practice has been going on for ages and more than 20% of prescriptions in the United States are prescribed off-label. A common example is the use of beta-blockers (approved for heart problems) for the treatment of performance anxiety.
GLP-1 agonist drugs, as discussed recently by metabolism.com. were originally approved for the treatment of Type 2 diabetes in adults. In the past few years most of these same medications have gained unprecedented popularity for their “off-label” weight loss benefit. Of the 5 GLP-1 agents presently in U.S. pharmacies only Wegovy (semaglutide) and Saxenda (liraglutide) are FDA approved for treating obesity. Of these two, Wegovy is the newer and had been much more popular that its sister drug Saxenda, probably due to being dosed only once weekly compared to daily for Saxenda and less likely to cause side effects. Due to Wegovy’s soaring popularity, its manufacturer, Novo Nordisk, increased the price of Wegovy two times since its initial release.
