Reasons We’re Getting Fatter

why we're getting fatterThe evidence that humans are getting fatter is rather apparent. Though it’s most noticeable in western countries, with the USA at the forefront, it’s also occurring in other regions of the world such as India and China as well as parts of Europe. What’s particularly alarming is the number of children and teens that are obese in America. Factor in the cases of type-2 diabetes, and even high cholesterol among this age group, and the cause for concern greatly escalates.

Projecting out a few decades, it’s not too difficult to imagine the increase in health care costs to treat these at-risk young people once they reach adulthood. The question that needs to be addressed is why is obesity on the rise in both adults as well as in children and teens?

It’s been observed that obese women are giving birth to obese offspring. The health risks for both mother and fetus are increased when the mother is obese [1]. It’s possible that the trait of obesity is being passed on to subsequent generations, however, it becomes quite literally a “chicken and the egg” paradox as to what’s turly behind this disturbing trend. Perhaps the search for an answer should begin with uncovering why, as a society, Americans are becoming heavier and unhealthier.

Fast Food Takeover

a SAD diet

Triple cheeseburgers, buckets of greasy chicken, and the obligatory super-sized soft drink to wash it all down with are what make up the typical fare at most fast food establishments. I’m old enough to remember when a McDonald’s was a rare sight in many towns and eating there was just the occasional treat after a movie or night out bowling.

They also didn’t have much competition unless you included diners and cafeterias. Back in the “Good Old Days”, most families still ate the majority of their meals together around the kitchen table and children either brought packed lunches to school or purchased, what was for the most part, a well-balanced school lunch.

Fast forward a lot of years to today and the landscape is vastly different.

Fast food chains of every variety are crammed along thoroughfares next to one another and many of us are now eating more and more of our meals at these places. The convenience and comfortable predictability of this way of eating becomes a very stubborn habit to break free of.

Fast food by design is created to have you craving more. Fat, sugar, and salt are all appetite stimulants and all are found in most fast food menu items in abundance. To make matters worse, fat is very calorie dense at 9 calories per gram and when you liberally sprinkle in loads of sugar in the way of soft drinks and dessert items, you quickly find yourself consuming more calories than you should be at a single meal. As the habit grows, the more you find yourself craving this kind of appetite-stimulating, calorie dense food.The average fast food meal ordered by adults contains 836 calories [2]. That may not seem like a lot, but when you factor in the other two meals of the day along with snacks and soft drinks, it’s not hard to get the daily total up around 3000 calories – more then most sedentary people require to maintain their basal metabolic rate.

Lack of Exercise and Technology Advances

technology and sedentary lifestyle

It’s no revelation that as a society, Americans don’t engage in enough physical activity in order to maintain a healthy body weight and it goes beyond just jumping around in an aerobics class or heaving weights off our chests. Back in the “Good Old Days”, and this time long before even I took in my first breath, people used the muscles of their bodies a whole lot more.

People thought nothing of having to walk just about every place they needed to go. Cars and public transportation were for really long excursions. They also had to move a lot more in general because the modern machinery and technology that we have today didn’t exist back then.

For the average family, calories consumed and expended either balanced out or were in a slight deficit so it was rare to encounter extremely overweight people. And yes, despite what passes for Gospel in some nutritional quarters (extreme low-carb), calories do matter.

Fast forward our time machine again back to today and we now find that too many people take in way more calories than they expend in the course of a typical day. It eventually reaches a point where getting things back into balance is an almost impossible task. Overcoming the inertia of a sedentary lifestyle combined with unhealthy eating habits is often more than most overweight people can deal with. It’s much easier to give in and continue on as usual since forcing yourself to diet and dragging yourself into a gym to be tortured by a Sadistic personal trainer isn’t going to make much of a difference anyway, so why suffer?

A Busy Society with Less Time

stress and weight gain

If the technology boom has been partially responsible to our declining activity levels, it’s also in part responsible for placing additional demands on our time as well as our immune systems. This all goes hand in hand with more demanding workloads, caring for children, and taking care of the daily responsibilities of life. You would think that these additional activities would actually help to burn more calories and at a certain level they do, but the downside is that individuals and families who are stretched for time also look to saving time when it comes to meal preparation and eating.

We’ve already touched on the fast food takeover. This habit is further fed by the general lack of time in today’s society. Eating out in general, beyond fast food joints, also becomes more common when time is at a premium. Though the menu choices may be somewhat healthier at “sit down” restaurants, what people actually select and the over-sized portions at many of these places often don’t work out to be much healthier than fast food.

And it’s not just eating out too much that gets us into dietary trouble. An over-reliance on highly-processed foods isn’t helping. You know, the stuff that comes in a box or plastic package. Many times it will even be touted as being low-fat, low-calorie, or even low-carb, but it’s certainly not a “healthy choice.” A quick check of the nutrition and ingredients labels should provide a quick tip off that things aren’t as advertised. Many times the first three ingredients (largest proportion of ingredients) contain sugar, high fructose corn syrup (aka sugar), vegetable oil (mostly likely containing trans fat if partially-hydrogenated), and white flour.

Stress and Not Enough Sleep

lack of sleep and weight gain

Along with our fast-paced, modern, tech-driven society also comes additional stress. This is also part of having less time to get things done. Our precious free time is also being whittled away – time in which we need to decompress and simply relax and enjoy the good things in life. Stress, besides being a silent killer that plays a role in hypertension and even psychological disorders, also has been shown to be an underlying cause of overweight and obesity due to stimulation of the “stress” hormone, cortisol [3,4].

If this wasn’t enough, there is also evidence to suggest that not getting sufficient sleep may contribute to our bodies laying down fat deposits. Just how much sleep is considered sufficient? Turns out that the old admonition from our parents to get 8 hours is what’s required to be on the safe side, but who really has the time to get a full 8 hours? Sometimes it just seems that the entire world is conspiring against us when it comes to maintaining a healthy body weight!

Quick Fix Weight Loss Solutions

If all the factors mentioned previously weren’t enough to make us tune out all the dire warnings and just curl up with a half-gallon of chocolate chip cookie dough ice cream, there is also the ever present industry of false hope that bombards us from every angle.

The diet pill and weight loss supplements industries are booming – along with the nation’s waistlines. We really need to pause and ask ourselves why this is. There are certainly no shortage of miracle prescription diets pills along with herbal supplements like acai berries, colon cleanse capsules, green tea supplements, ephedra supplements, and the list goes on and on.

Have you ever personally met or known anyone who has lost significant weight on any of these products and kept it off? It seems the only ones who claim to have lost weight as a result of using these products are the fake people in the fake blogs and fake news articles that pollute the Internet.

Losing excess weight in the form of fat loss and keeping it off is not an easy process – at least not as easy and painless as these “Miracle Diet Pills” would lead you to believe. But it also is not as difficult as you’ve probably led yourself to believe if you choose to go the route of a healthy and practical eating regimen that you can follow for the rest of your life in order to keep the excess pounds off.

It takes some effort and determination as well as planning, but the rewards will last you a lifetime. Hopefully, a lifetime that is both long and healthy!

Some Suggestions

Below are a few suggestions for getting on track for cleaning up your eating habits as well as fortifying yourself against the slings and arrows of daily living:

  • Cook more. If you don’t know how, resolve to learn. It doesn’t have to be gourmet and there are plenty of online resources in the way of blogs and videos to help you along. There are plenty of low-carb recipes right here on the blog as well as cooking videos on my YouTube channel.
  • Plan your meals. Nothing obsessive, just make sure you shop for groceries at least weekly and purchase whole, fresh foods.
  • Start bringing your lunch to work or school at least twice a week. You’ll eat less, it’ll be healthier and you’ll save some money in the process.
  • Stop drinking soda, sugary sports and energy drinks, and alcoholic drinks with sugary mixers. Cutting down on beer will also cut down on a developing “beer” gut.
  • Eat breakfast.
  • Eat a healthier breakfast. Instead of a bagel or corn flakes, try eggs, oatmeal, yogurt, or some fruit and whole grain toast.
  • Have healthy snack foods on hand in case you get hungry between meals. See this post on low-carb snack ideas – they work even if you don’t eat low-carb.
  • Instead of dosing off in front of the TV after dinner, take a walk or spend some quality time with your family.
  • Try getting to bed earlier if possible.
  • Go for a quick walk on your lunch break. You’ll have more time if you bring your lunch (hint, hint).
  • Let go of things that are out of your control – especially work or social issues. You don’t always need to be right – even if you know that you are.
  • Blow off steam playing a competitive sport or working out.


The Green Coffee Bean Extract Study and Misleading Research

Green Coffee BeansAs a reader of this blog you are probably interested in maintaining a healthy weight by following an eating plan that’s appropriate for your metabolic type, exercising intelligently, and if beneficial, bolstering your efforts with a little help from nutritional supplements. You want information that is based on sound principles of scientific research for all of these things, especially when it comes to nutritional supplements.

But how can you know that a health benefit claim of a supplement manufacturer is legitimate or not? After all, no one wants to waste their hard-earned money on products that don’t work as claimed or worse, are potentially dangerous. Let’s explore the issue of evaluating supplement research and claims for scientific validity by examining a very popular and highly-touted weight loss supplement: Green coffee bean extract (GCBE).

GCBE is an extract that is made from unroasted coffee beans. Coffee beans are naturally green in color prior to the roasting process. A cup of Joe made from green coffee beans would taste terrible as you might imagine. The active ingredient in GCBE is thought to be chlorogenic acid. The product we’ll examine is standardized to contain 46% chlorogenic acid.

In The Land of Oz

The GCBE craze started when America’s favorite TV doctor, Dr. Oz, promoted GCBE on his show as the new miracle weight loss supplement.

He waxed eloquently about a study presented before the largest scientific society (American Chemical Society) that yielded a 17 lb. weight loss in 12 weeks and a16% reduction in total body fat all while consuming a 2400 calorie diet. And ready for this? All without any exercise! Where do I put my credit card info?

There was only one problem: the research was heavily flawed and Dr. Oz should have at least taken the time to evaluate it before making such fantastic claims. He remained steadfast, however, in these claims even when called before a Congressional hearing on weight loss supplements.

Scientific Research Study

The first question that should always be asked about any study, regardless of its claims, is who sponsored the research? This little detail is vital when it comes to sniffing out any potential bias resulting from a vested financial interest based upon the outcome of the study whether it be positive, negative or neutral.

In the 1950s with increasing evidence that cigarette smoking caused lung cancer the tobacco giant, Phillip Morris, created an entity known as the Tobacco Institute Research Committee (TIRC) to sponsor research into this supposed link. PM hired a cancer researcher who believed cancer was entirely due to genetics and not to any extraneous factors such as harmless cigarette smoke. Research was funded with this biased focus. Needless to say no relevant data came out of this research [1].

The research for GCE was sponsored by a supplement company in Austin, TX, the maker of the GCBE evaluated in the study. This doesn’t automatically mean the study is flawed scientifically. It’s just a red flag that must be evaluated along with the rest of the methodologies employed in the study. Appropriate credit should be given to any supplement manufacturer that goes through the expense and trouble of sponsoring a legitimate scientific study of their product to show efficacy and safety.

Next, we need to consider where the study was conducted. Was it conducted at an institution that has integrity and reputation for quality scientific research? The GCE was conducted at the Health Sciences Clinic in Bangalore, India. While the name Health Sciences Clinic sounds impressive, an Internet search came up empty.

What about the researchers themselves? Are they recognized leaders in this field? The paper lists three authors: Joe A Vinson, Bryan R Burnham, and Mysore V Nagendran. Typically, the first author named is the lead scientist and has the most time invested in the study followed by the second author. The last author is usually the person in whose lab the study was conducted in.

Both Vinson and Burham are located at the University of Scranton in Pennsylvania; a small private Catholic and Jesuit school. Vinson is in the chemistry department. His homepage on the University’s website is a long rambling read that has very little to with his science background. In fact, I don’t think I’ve seen anything quite as bizarre for an academic’s homepage. He provides such interesting tidbits such as to how his mother went to high school with Pretty Boy Floyd and in his first play of his burgeoning amateur acting career; he was cast as the Fireman in Eugene Ionesco’s absurdist comedy The Bald Soprano. Said fireman goes around in pink long underwear putting out fires. A noble endeavor indeed, but how this is relevant to Vinson’s qualifications as a scientist seem tangential at best. ( Burham is in the psychology department. A Google search of Nagendran turns up empty other than mentions of this study.

Research Report

Another consideration is where were the results published? Prestigious journals like Science and Nature would really cause one to sit up and take notice. This study was posted in the journal Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy. As impressive as this may sound, it turns out that the publication is an open access journal as opposed to a subscription-only journal.

Open access journals are a product of the Internet age. They enjoy the advantage of anyone being able to view the entire article without paying a fee with the attendant disadvantage (or advantage depending on which side you’re on) of potentially undermining the peer review process, which is vital to any sound research study. Some publishers will just accept a fee from the authors without adequate peer review. In fact, a staff writer for Science critical of these journals submitted a deliberately flawed study that in many cases was accepted to these types of journals. There are a few solid open-access publishers. The publisher of this particular journal is not one of them.

The house of cards the GCBE study was based on is beginning to come into focus at this point. Let’s now have a look at the study itself. You’ll hear Dr. Oz and his ilk spouting. “In a randomized, double-blind, placebo controlled study” to get you really juiced up about all the science behind the product they’re pushing. Yes, this is important, but neither the research subjects nor the persons conducting the study should know who is getting the supplement in order to satisfy the double-blind claim. In the case of this study, that would be knowing which subjects received the GCBE or a placebo pill containing no GCBE. Problems with this particular study can be discovered early on by simply reading the Materials section of the published report.

First of all, the study involved a small number of people: 16. This is an extremely small sample size and whatever statistically significant data can be derived from it is highly questionable. The subjects were then divided into three groups and all were given a high dose of GCBE for 6 weeks, low dose GCBE for 6 weeks, and a placebo for six weeks. There was a two week period between each treatment when nothing was administered.

Double Blind Research Trials

The only difference between these three groups is the order in which they were administered the three different treatments. A crucial control group is missing: a group that got only the placebo throughout the study. The other problem is the high dose and the low dose treatments were readily apparent to both the research subject and the researcher since only two pills were taken per day for the low dose segment and three pills for the high dose segment. All groups lost weight in the initial six weeks of the study, even in the placebo group [2].

The 8 kg or 16 lb. lost after 22 weeks of the study is deceiving, and the data would suggest it had more to do with the daily monitoring of their diet [3]. If we look at the data for the high dose GCBE, it would be a more modest 2 kg or 4 lb. of weight lost after 22 weeks.

In summary a study should be designed to:

  • Have adequate controls in place to eliminate results that are due to other factors. Admittedly, controls can become unwieldy especially in human studies. In this case, it would appear the effects of the study were more due to the daily monitoring of the subjects’ diet. The missing control group of receiving only placebo throughout the study would have flushed this out.
  • Be double-blinded which means neither the researcher nor the subjects should know who is getting the supplement or a placebo until the end of the experiment.
  • Be randomized which means that the subjects are randomly selected for each treatment group. There is something suspicious in this study since one of the treatment groups starts the trial at a considerably lower mean weight.
  • Have an adequate sample size so statistically significant results can be reported with confidence.

It turns out that initially the paper was submitted to a journal that had some integrity but they rejected it for publication. It was only then that Vinson and Burham were recruited by the supplement company to lend their scientific gravitas as well as to rework the paper. While they noticed discrepancies and asked for clarification from India, they never reviewed the raw data or questioned the changed numbers.

FTC Investigation

The FTC then got involved and demanded to see the data and found that the Indian researcher had in some cases changed the final weights and even the duration of the study. Vinson and Burham caught “green-handed” had no choice but to send a retraction to the journal. The FTC fined the supplement company 3.5 million dollars.

The FTC deserves a great deal of credit going after these fraudsters. Obviously, some reforms need to be implemented by the supplement industry to protect the consumer against false claims. The FTC has suggested requiring two independent studies be conducted before claims can be made. I would suggest some method to provide more separation between the supplement companies and the researchers. Another added protection is to force the supplement companies to submit the trial parameters to before the start of the study so it can’t be altered after the fact [4]. Sometimes, government regulation is a necessary evil. The alternative is to let the wolves to roam free to prey on the unsuspecting and defenseless.
