The old saying, â€œThe way to a manâ€™s heart is through his stomachâ€ implies there is a deep connection between emotions and eating. My guess is Â no one is really surprised by this idea. Both men and woman can identify ways in which their mood and appetite are intertwined and it is no mere quirk of manâ€™s personality that this is true.
Evolution tells us that we were born to eat. The earliest creatures in the worldâ€™s history were simple eating machines. Their bodies consisted of an entrance for food, a digestive tract and an exit for refuse. In order to become more efficient at getting food creatures developed a system to locate food and to move toward it. This system is known as a nervous system. The first creature to have this ability is the worm. Eventually the nervous system controlling the digestive system (enteric nervous system) began to sprout nodes which were early brains.Â As time went on and the brain became better developed it split off from the nervous system that controlled the digestive tract. Everything that followed in evolution, has served the purpose of developing Â increasingly efficient brains (central nervous system) for acquiring the fuel of life.
Another example of how deeply connected the gut and brain are, is to look at the development of the fetus. When a human fetus is still just a lump of jelly, the digestiveÂ and nervous systems are one structure. Soon this organ splits into two, one to become our gastrointestinal tract and the other the brain and spinal cord (central nervous system). Even though they become physically separated the chemical signals used by the gut and nervous system remain virtually identical. These chemicals comprise the groups known as neurotransmitters and hormones.
The same chemicals in the digestive tract that cause the intestines to twist and convulse (peristalsis), in the brain stimulate the emotion of anxiety. This explains why people get “butterflies” in the stomach or diarrhea when they are nervous.Â The brain chemicals involved in depression can cause constipation. Â The syndrome of irritable bowel disease (IBS) with its cycles of diarrhea and constipation is thought to be a reflection of an emotional rollercoaster. Â The chemical relationship between mood and appetite is even more complex but no less real. One of the most common side effect of mood altering drugs is increased appetite and weight gain. Just ask anyone who has been on an anti-depressant drug such as Prozac, Zoloft or Abilify. Â The chemical in marihuana that gets people high is famous for triggering the eating binge called “the munchies”.
Appetite suppressant drugs often have effects on mood and can be the source of major side effects. One new generation of appetite suppressants being developed, Acomplia, failed to be approved by the FDA because it caused severe depression and suicidal thinking.
In the next part of this series we will look at ways we can influence the brain to control our appetite.
Polycystic Ovarian Syndrome (PCOS) sounds like a rare disorder but it is surprisingly common. This is a disorder with onset in early adolescence effecting up to 10% of young women. Characteristic signs and symptoms include increasing facial and body hair, hair loss from the scalp, muscular or heavy build, acne, thickening and darkening of the skin known as acanthosis nigricans, blood sugar problems including type 2 diabetes, high cholesterol and irregular menstrual cycles and infertility. In older women with PCOS coronary artery disease is more common. In severe cases deepening of the voice and enlargement of the clitoris (clitoromegaly) can be seen. Before the underlying hormone disorders were clarified, the main method of diagnosing this disorder was by finding multiple cysts on the ovary. We now understand that the main problem is not the ovarian cysts but metabolic disorders including insulin resistance and elevated male hormone levels (testosterone) in the blood.
Another misconception about PCOS is that it only occurs in overweight women. Obesity is common in PCOS but thin women are also capable of developing PCOS. The underlying hormone problems are complex but are thought to be at least in part due to high insulin levels in the blood resulting from insulin resistance. With insulin resistance the body requires high levels of insulin due to insensitivity of the tissues to insulinâ€™s presence. What treatments are available for PCOS? There are very few, if any, drugs specifically approved for the treatment of PCOS. This is probably because of the low profit potential for treating this disorder. Drug companies cannot afford to invest millions of dollars in research because almost all of the existing standard therapies are generic drugs. Some of the most useful medications for treating PCOS are drugs used to treat type 2 diabetes because of their effect to reduce insulin resistance. These drugs are metformin and Actos. Metformin is the most popular oral medication for diabetes treatment in the U.S. Actos has been available for about 10 years but due to recent negative publicity about an unproven risk of bladder cancer, its popularity is declining. Neither drug is approved by the FDA for treatment of PCOS but multiple studies confirm the clinical and hormonal benefits of using these medications in this disorder. In 2011 research was published in the Journal of Clinical Endocrinology and Metabolism suggesting that the generic cholesterol lowering drug, simvastatin may also show benefits similar to metformin for the treatment of PCOS.
In the late 1980â€™s, I along with Dr. Lester Gabrilove at Mt. Sinai Hospital in New York, published our research showing that an anti-fungal medication, ketoconazole, could reverse the hormonal, physical and metabolic problems associated with PCOS. Due to the potential toxicity of ketoconazole this therapy never gained wide spread acceptance. The manufacturer refused to fund additional studies to determine how to more effectively use this drug, due to the low profit potential and liability concerns.
This information is strictly for educational puroses. 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.
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.
by Gary M. Pepper, M.D. and Sam Jeans, MSc The global anti-obesity drug market, in 2021was valued at over $2 billion. Within one year this figure had skyrocketed to $8 billion and is expected to climb to nearly $ 20 billion by 2027. This astounding growth is a reflection of soaring obesity rates, and the arrival of a new class of weight loss medication fueling a craze both in the USA and across the world.
The FDA and global health regulators, until very recently, had maintained a very tight ship when it comes to treating obesity with medication, placing the emphasis on diet and exercise rather than weight loss drugs. Since the 80s, anti-obesity drugs continued to be controversial, and a more stringent FDA implemented ongoing safety trials along with other precautions. There is some speculation that a shift in attitude toward approval of weight loss medication by the FDA , is underway
Weight loss drug controversies are far from over and, in fact, may soon rival the amphetamine crisis of the 70’s. For that reason, metabolism.com has felt it important to provide our guide to weight loss drug issues, past and present.
Anti-Obesity Drugs Timeline
Prescription drugs for lifestyle diseases such as obesity were marketed heavily throughout the 1950s to the 1970s. Amphetamines entered the public domain after the Second World War where they were used extensively in the military.
In the 50s, walk-in clinics prescribed diet pills with other medications almost at random, with or without genuine concern for one’s weight. These brightly colored pills became known as “rainbow pills”.
In the 1960s and 1970s, the so-called “rainbow pill diet” of pills was finally coming to an end as the FDA began to systematically ban many of the drugs involved. A high-profile expose by investigative journalist Susanna Mcbee, published in Life magazine, brought attention to this new modern public health crisis.
The rainbow pill diet combined amphetamines, laxatives, thyroid hormones, and even diuretics to produce extreme weight loss, combined with benzodiazepines, barbiturates, and steroids to reduce side effects, and antidepressants to suppress medication-induced insomnia and anxiety.
In 1968, rainbow pills were linked to over 60 deaths, with numerous accounts of their devastating impact surfacing in the news and media. Within just two months, 48 million pills were seized and destroyed. Nevertheless, amphetamine-based diet pills remained extremely popular throughout the 1970s. In 1978, some 3.3 million prescriptions for amphetamines were written each year, with some 50 million pills a year ending up in the black market.
In 1979, the FDA banned amphetamines as a weight loss aid, but that is hardly the end of the USA’s love affair with obesity medication.
Here’s a brief timeline of recent anti-obesity drugs:
