Another Diet Pill Bites the Dust

Author: Dr. Stephen Chaney

New Year DietThe New Year is upon us, and everyone is looking for an easy way to lose weight.

Let’s face it. Losing weight is difficult. You have to give up your favorite foods. You’re often hungry and cranky. You have to change your lifestyle. And did I mention that you might need to put on your running shoes and go for a run or, heaven forbid, actually go to the gym.

It’s so much easier to take one of those diet pills. You know the ones I’m talking about. They promise to give you energyburn the fatsuppress your appetite. All you need to do is take one of those little pills every day and, voila, you’re ready to try on that bikini.

It all sounds great. But are those diet pills really safe? A few weeks ago I shared with you that the experts have warned against the use of fat burning sports supplements. They consider them unsafe. Now it’s time to turn our attention to the fat burning diet pills.

Are Diet Pills Safe?

Lots of diet pills have come and gone over the years. Some have just faded away because they didn’t work. They didn’t live up to their claims. Others have been withdrawn from the market by regulatory agencies because they were dangerous or actually killed people- Ma huang and Fen-Phen come to mind, but there have been many others.

And now it looks like yet another diet pill, one called Dexaprine, may have the same fate.

The ads make it sound like a wonder pill.

  • “With one little change…you could feel energy all day long”
  • “With one little change…you can suppress your insatiable appetite”
  • “You can try another unsuccessful diet without it, but when you’re ready…the ultimate fat burner will be waiting for you with open arms.”

The Dark Side

And yet, like most diet pills, it also has a dark side. Side effects include insomnia, sweating, heart palpitations and high blood pressure. As if that weren’t bad enough, the supplement manufacturer that makes Dexaprine conducts no clinical studies on their products, so they have no idea whether their product is safe or not.

And, it appears that it may not be safe. Dutch authorities banned Dexaprine in August after reports of 11 adverse reactions associated with Dexaprine use in Holland since March of this year, including hospitalizations and severe heart problems. British authorizes followed suit the next day and issued a warning against use of “fat burner” supplements in general. It’s probably just a matter of time before other governments step in and ban Dexaprine as well.

And, it’s not just Dexaprine. New diet pills hit the market almost every day. And, they all have those same “magical” claims.

The Only Safe Drug Is A New Drug

It reminds me of the wise advice that a physician colleague of mine gave to the medical students near the start of their first year. He told them “The only safe drug is a new drug”. He went on to say that he didn’t mean that new drugs were safer than the older drugs. It’s just that we don’t know all of their bad side effects until they’ve been on the market for a few years.

Diets pills are no different. They burst on the market full of promise. But, once they’ve been on the market for a year or two, reports of their bad side effects start to appear. We start to learn just how dangerous they are. And, one by one, they all bite the dust.

The Bottom Line

1)     There is no “Tooth Fairy”. There is no “Easter Bunny”. And, there is no magical pill that will SAFELY melt the pounds away. You simply don’t want to risk the diet pill solution – no matter how easy it sounds. No magical, “quick fix” diet solution is worth risking permanent heart damage – or worse.

2)     If you are fortunate to lose weight safely using one of those diet pills, you won’t have learned anything. You won’t have changed anything. The weight will come right back on.

3)     Permanent weight loss requires a permanent change to your lifestyle. Some of those changes will be difficult at first, but once those lifestyle changes become habits – once they become part of who you are, they will become easy.

You can achieve both the weight and the health you want!

The Two Biggest Misconceptions About Supplementation

Written by Dr. Steve Chaney on . Posted in Issues, Supplements and Health

Secrets You Need To Know

Author: Dr. Stephen Chaney

Nutrition MythsIn last week’s “Health Tips From The Professor” I told you the truth behind the headlines that vitamins are a waste of money. This week I’m going to be talking about the two biggest misconceptions that people have about supplementation. These are two secrets you need to know.

The Two Biggest Misconceptions About Supplementation

I won’t keep you in suspense. The answer is pretty simple. The two biggest misconceptions about supplementation that I hear over and over are:

1)     Supplementation can cure disease

2)     It doesn’t matter what you eat (or what supplements you take)

Of course, those statements don’t tell you much by themselves, so let’s delve into the subject more deeply.

Misconception #1: Supplementation can cure disease.

I don’t know how many times I’ve been asked “I have “disease X”. What supplements should I take? – as if supplements were drugs that can be taken to cure a disease.

We shouldn’t think of supplements as drugs that cure diseases. We should think of them as providing the nutrients that are the building blocks of health – or perhaps the ammunition that the body uses to fight diseases. Diseases, after all, are an abnormal state of being, and our bodies have an amazing capacity to fight those diseases.

When we have infections or cancer our body activates its immune system to fight it. When we have inflammation our body tries to put out the fire. When we have damage to our DNA – our genetic information – our body tries to repair it. The list is almost endless. Our bodies are wondrously designed!

Our immune systems require nutrients like protein, B vitamins, antioxidants, zinc and iron. The omega-3 fatty acids, anti-oxidants and polyphenols like resveratrol are anti-inflammatory. Nutrients like antioxidants and polyphenols support DNA repair.

So proper diet and supplementation are not “magic bullets” that cure diseases. They are simply the building blocks that allow the body to do what it does best.

And because no two of us are alike the nutrients that we need the most to allow our bodies to do their job efficiently may be different for each one of us.

So while there is no magic food or supplement that will cure a specific disease, a healthy diet and a holistic approach to supplementation can often work wonders.

Misconception #2: It doesn’t matter what you eat.

This is the flip side of the coin. I often come across people who have been told by the “experts” that the cause of their disease was not related to diet so they shouldn’t worry about what they eat. They are also usually told that supplementation will not do any good.

Let’s take the most extreme example – genetically caused diseases or serious degenerative diseases like multiple sclerosis or Parkinson’s for which the causes are still not fully understood.

It is generally true that these diseases were not caused by poor diet (MS may be the exception because there is some evidence that it can be caused by inadequate vitamin D during childhood). And I know many people who take the “expert’s” advice to heart and eat whatever they like and consider supplementation a waste of money.

Is that a sound approach? Let’s consider.

Any nutritionist will tell you that an inadequate diet can lead to malaise, low energy, inflammation, weakened immune system and impaired wound healing – just to name a few maladies. Even if you don’t end up with the symptoms of a nutritional deficiency, a poor diet can rob you of energy and vitality.

If you layer the consequences of a poor diet on top of the underlying disease, your chances of being able to cope with the disease and function optimally are greatly diminished.

I have come across many people with very serious diseases who are able to function at a very high level through proper diet and a holistic approach to supplementation.

Diet and supplementation did not cure their disease as they quickly discover if they stop supplementing and go back to the way they used to eat, but in many cases you would consider them to be perfectly healthy as long as they keep doing what they have been doing.

The Bottom Line

1) There is no perfect food or supplement that is capable of curing disease, but if you give your body the nutrients that it needs it often has the ability to heal itself.

2) Proper diet and supplementation can make a difference even if the disease was not caused by poor nutrition.

3) Each of us have unique nutritional needs so a holistic approach to diet and supplementation is best.

I didn’t specifically talk about weight control and exercise, but you should know from my previous “Health Tips From The Professor” that I consider them to be an essential part of any holistic health program.

What Is The Planetary Diet?

Is Your Diet Destroying The Planet?

Author: Dr. Stephen Chaney

 

Earth Day has come and gone, but you are still committed to saving the planet. You save energy. You recycle. You drive an electric car. But is your diet destroying the planet?

This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019 ) serves as a dire warning of what will happen if we don’t change our ways. I touched on this report briefly in a previous issue of “Health Tips From The Professor,” What Is The Flexitarian Diet , but this topic is important enough that it deserves an issue all its own.

The commission carefully evaluated diet and food production methods and asked three questions:

  • Are they good for us?
  • Are they good for the planet?
  • Are they sustainable? Will they be able to meet the needs of the projected population of 10 billion people in 2050 without degrading our environment.

The commission described the typical American diet as a “lose-lose diet.” It is bad for our health. It is bad for the planet. And it is not sustainable.

In its place they carefully designed their version of a primarily plant-based diet they called a “win-win diet.”  It is good for our health. It is good for the planet. And, it is sustainable.

In their publication they refer to their diet as the “universal healthy reference diet” (What else would you expect from a committee?). However, it has become popularly known as the “Planetary Diet.”

I have spoken before about the importance of a primarily plant-based diet for our health. In that context it is a personal choice. It is optional.

However, this report is a wake-up call. It puts a primarily plant-based diet in an entirely different context. It is essential for the survival of our planet. It is no longer optional.

If you care about global warming…If you care about saving our planet, there is no other choice.

How Was The Study Done?

The study (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019 ) was the report of the EAT-Lancet Commission on Healthy Diets from Sustainable Food Systems. This Commission convened 30 of the top experts from across the globe to prepare a science-based evaluation of the effect of diet on both health and sustainable food production through the year 2050. The Commission included world class experts on healthy diets, agricultural methods, climate change, and earth sciences. The Commission reviewed 356 published studies in preparing their report.

 

Is Your Diet Destroying The Planet?

When they looked at the effect of food production on the environment, the Commission concluded:

  • “Strong evidence indicates that food production is among the largest drivers of global environmental change.” Specifically, the commission reported:
  • Agriculture occupies 40% of global land (58% of that is for pasture use).
  • Food production is responsible for 30% of global greenhouse gas emissions and 70% of freshwater use.
  • Conversion of natural ecosystems to croplands and pastures is the largest factor causing species to be threatened with extinction. Specifically, 80% of extinction threats to mammals and bird species are due to agricultural practices.
  • Overuse and misuse of nitrogen and phosphorous in fertilizers causes eutrophication. In case you are wondering, eutrophication is defined as the process by which a body of water becomes enriched in dissolved nutrients (such as phosphates from commercial fertilizer) that stimulate the growth of algae and other aquatic plant life, usually resulting in the depletion of dissolved oxygen. This creates dead zones in lakes and coastal regions where fish and other marine organisms cannot survive.
  • About 60% of world fish stocks are fully fished and more than 30% are overfished. Because of this, catch by global marine fisheries has been declining since 1996.
  • “Reaching the Paris Agreement of limiting global warming…is not possible by only decarbonizing the global energy systems. Transformation to healthy diets from sustainable food systems is essential to achieving the Paris Agreement.”
  • The world’s population is expected to increase to 10 billion by 2050. The current system of food production is unsustainable.

When they looked at the effect of the foods we eat on the environment, the Commission concluded:

  • Beef and lamb are the biggest contributors to greenhouse gas emissions and land use.
  • The concern about land use is obvious because of the large amount of pasture land required to raise cattle and sheep.
  • The concern about greenhouse gas emissions is because cattle and sheep are ruminants. They not only breathe out CO2, but they also release methane into the atmosphere from fermentation in their rumens of the food they eat. Methane is a potent greenhouse gas, and it persists in the atmosphere 25 times longer than CO2. The single most important thing we can do as individuals to reduce greenhouse gas emissions is to eat less beef and lamb. [Note: grass fed cattle produce more greenhouse gas emissions than cattle raised on corn because they require 3 years to bring to market rather than 2 years.]
  • In terms of energy use beef, lamb, pork, chicken, dairy and eggs all require much more energy to produce than any of the plant foods.
  • In terms of eutrophication, beef, lamb, and pork, all cause much more eutrophication than any plant food. Dairy and eggs cause more eutrophication than any plant food except fruits.
  • In contrast, plant crops reduce greenhouse gas emissions by removing CO2 from the atmosphere.

 

What Is The Planetary Diet?

In the words of the Commission: “[The Planetary Diet] largely consists of vegetables, fruits, whole grains, legumes, nuts, and unsaturated oils. It includes a low to moderate amount of seafood, poultry, and eggs. It includes no or a very low amount of red meat, processed meat, sugar, refined grains, and starchy vegetables.”

When described in that fashion it sounds very much like other healthy diets such as semi-vegetarian, Mediterranean, DASH, and Flexitarian. However, what truly distinguishes it from the other diets is the restrictions placed on the non-plant portion of the diet to make it both environmentally friendly and sustainable. Here is a more detailed description of the diet:

  • It starts with a vegetarian diet. Vegetables, fruits, beans, nuts, soy foods, and whole grains are the foundation of the diet.
  • It allows the option of adding one serving of dairy a day (It turns out that cows produce much less greenhouse emissions per serving of dairy than per serving of beef. That’s because cows take several years to mature before they can be converted to meat, and they are emitting greenhouse gases the entire time).
  • It allows the option of adding one 3 oz serving of fish or poultry or one egg per day.
  • It allows the option of swapping seafood, poultry, or egg for a 3 oz serving of red meat no more than once a week. If you want a 12 oz steak, that would be no more than once a month.

This is obviously very different from the way most Americans currently eat. According to the Commission:

  • “This would require greater than 50% reduction in consumption of unhealthy foods, such as red meat and sugar, and greater than 100% increase in the consumption of healthy foods, such as nuts, fruits, vegetables, and legumes.”
  • “In addition to the benefits for the environment, “dietary changes from current diets to healthy diets are likely to substantially benefit human health, averting about 10.8-11.6 million deaths per year globally.”

What Else Did The Commission Recommend?

In addition to changes in our diets, the Commission also recommended several changes in the way food is produced. Here are a few of them.

  • Reduce greenhouse gas emissions from the fuel used to transport food to market.
  • Reduce food losses and waste by at least 50%.
  • Make radical improvements in the efficiency of fertilizer and water use. In terms of fertilizer, the change would be two-fold:
    • In developed countries, reduce fertilizer use and put in place systems to capture runoff and recycle the phosphorous.
    • In third world countries, make fertilizer more available so that crop yields can be increased, something the Commission refer to as eliminating the “yield gap” between third world and developed countries.
  • Stop the expansion of new agricultural land use into natural ecosystems and put in place policies aimed at restoring and re-foresting degraded land.
  • Manage the world’s oceans effectively to ensure that fish stocks are used responsibly and global aquaculture (fish farm) production is expanded sustainability.

What we can do: While most of these are government level policies, we can contribute to the first three by reducing personal food waste and purchasing organic produce locally whenever possible.

What Does This Mean For You?

If you are a vegan, you are probably asking why the Commission did not recommend a completely plant-based diet. The answer is that a vegan diet is perfect for the health of our planet. However, the Commission wanted to make a diet that was as consumer-friendly as possible and still meet their goals of a healthy, environmentally friendly, and sustainable diet.

If you are eating a typical American diet or one of the fad diets that encourage meat consumption, you are probably wondering how you can ever make such drastic changes to your diet. The answer is “one step at a time.”  If you have read my books “Slaying The Food Myths” or “Slaying the Supplement Myths,”  you know that my wife and I did not change our diet overnight. Our diet evolved to something very close to the Planetary Diet over a period of years.

The Commission also purposely designed the Planetary Diet so that you “never have to say never” to your favorite foods. Three ounces of red meat a week does not sound like much, but it allows you a juicy steak once a month.

Sometimes you just need to develop a new mindset. As I shared in my books, my father prided himself on grilling the perfect steak. I love steaks, but I decided to set a few parameters. I don’t waste my red meat calories on anything besides filet mignon at a fine restaurant. It must be a special occasion, and someone else must be buying. That limits it to 2-3 times a year. I still get to enjoy good steak, and I stay well within the parameters of the Planetary diet.

Develop your strategy for enjoying some of your favorite foods within the parameters of the Planetary Diet and have fun with it.

The Bottom Line

 

Is your diet destroying the planet? This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report serves as a dire warning of what will happen to us and our planet if we don’t change our ways.
