Go with Your Gut: The Science Behind Your Gut Bacteria

Go with Your Gut: The Science Behind Your Gut Bacteria

“Going with your gut”, a common phrase meaning to go with your feelings and intuition now has another meaning. Beyond a sixth sense, going with your gut can now reference that you are focusing on something much larger- about 100 trillion times larger, in fact. You read right, 100 trillion times. What am I talking about? If you guessed gut bacteria (aka the microbiome, microbiota, or microflora) you are correct!

But what exactly is gut bacteria, what does it do for my health, and how can I support a community of 100 trillion cells?!

100 trillion? Really?

Yup, turns out the microbiome and Zimbabwe’s currency (their 100 trillion dollar note actually exists) have something in common. If you are thinking that 100 trillion sounds like a crazy large number, you are not alone. Many friends and family members have asked me a variation of the following question: “How do 100 trillion cells fit in my gut?” My response usually involves something to the extent of “Bacteria are really, really small.”

That’s cool and all, but what are bacteria?

So glad you asked! Bacteria are tiny (microscopic!) single celled organisms. Bacteria are extremely prevalent on Earth, having been found in disparate locations ranging from 40 miles up in the atmosphere to miles underneath the ocean’s surface. Additionally, bacteria are found throughout the human body.

Large communities of bacteria on the skin, in the gut, and reproductive organs make up distinct profiles, classified as the microbiome. Microbes can be divided into classes based on different characteristics, with some classes contributing to health, while others classes cause infection and disease. For the microbiome, there are three predominant microbial classes that have been associated with a “healthy” microbiome: Bacteroidetes, Actinobacteria, and Firmicutes.

What’s with all the health hype? 

Recent research has shown that the microbiome positively promotes health by aiding in digestion, providing energy and nutrients that are difficult to acquire, outcompeting harmful bacteria, and training the immune system. Sounds great, right? I think those are enough reasons for all of the recent interest and coverage. However, it’s not the only piece of the puzzle.

Just like most good things have fine print, the microbiome is no exception. Altered microbiome profiles have been linked to chronic diseases like obesity, inflammatory bowel conditions, cancer, and cardiovascular disease, and much is still unknown about these interactions and associations.

So what can I do to nourish my microbiome?

Nourishing your microbiome starts with nutrition. You may have heard of the terms prebiotics and probiotics. These “biotics” are the two primary ways you can support your microbiome. Breaking down the two words can get at what these things actually do for the microbiome. “Biotic” means relating to, or resulting from living things, especially in their ecological relations. “Pre” means before and “pro” means to stimulate or support. So just by looking at the words alone, you can get a pretty good sense of what they do for the microbiome.

Basically, prebiotics are the “food” used by microbiome. Prebiotics are composed of complex carbohydrates that can predominately be digested by microbiome. Some examples of prebiotics include inulin, polydextrose, fructooligosaccharides (FOS), and galactooligosaccharides (GOS).

On the other side of the equation are the probiotics. Probiotics contain microbiome-promoting bacteria. Common probiotic strains include Bifidobacterium, Streptococcus, and Lactobacillus, which have been shown to support a healthy microbiome. However, just because you may see these strains listed on food ingredients does not necessarily mean these foods will have a probiotic effect. For this reason, in order to be classified as a probiotic, the specific strains must result in proven health benefits and/or contain more than 108 organisms per gram (i.e. 100 million bacterial cells/gram) at the end of manufacturing.

Where can I find prebiotics and probiotics?               

In case the words inulin, FOS, and GOS don’t mean much to you, the following foods are rich sources of prebiotics: bananas, honey, whole grains, artichokes, leeks, onions, and garlic. In addition, you can find prebiotics in fortified foods and beverages. Aim to eat about 2-30 grams per day of prebiotics, which can be achieved from eating ¼ of an onion, 1 banana, and about ½ cup whole wheat flour (or something that has been made with ½ cup whole wheat flour. As for probiotics, yogurt, buttermilk, kefir, kombucha, kimchi, sauerkraut, miso, tempeh and other fermented foods contain probiotics. If you’d rather get your dose of probiotics in the form of a supplement, go for it.

Myths about microbiome

What about the relationship between low-calorie sweeteners and the microbiome?

Advertising

You may have heard or read the most recent article that linked low-calorie sweeteners and negative modifications to the microbiome. However, coverage from media stories often leaves out critical details (design, results and limitations) from research studies and most often tells and sells a story based on one study that is counter to what the totality of scientific research in the area concludes.

The majority of media stories about the role of low-calorie sweeteners on the microbiome use the same few studies performed in animal models, and try to pose that the findings have direct implications to human health. Excuse me? This should not happen and these articles should shift their focus to research stemming from clinical trials (the gold standard). In case you were wondering, there are no published studies that assess the relationship and impact of low-calorie sweeteners on the microbiome in humans.

So there you have it, yet another reason to go with your gut to support your overall health. Try to incorporate prebiotics and probiotics into your diet. Don’t let the myths and misinformation about the microbiome bog you down, but rather, stick to the science and your gut will be good to go!

7 Simple Rules to Live by to Get in Shape in Two Weeks

7 Simple Rules to Live by to Get in Shape in Two Weeks

Learning how to get in shape and set goals is important if you’re looking to live a healthier lifestyle and get closer to your goal weight. While this does require changes to your daily routine, you’ll find that you are able to look and feel better in only two weeks.

Over the years, I’ve learned a lot about what it takes to get in shape. Although anyone can cover the basics (eat right and exercise), there are some things that I could only learn through trial and error. Let’s cover some of the most important points for how to get in shape in two weeks.

1. Exercise Daily

It is far easier to make exercise a habit if it is a daily one. If you aren’t exercising at all, I recommend starting by exercising a half hour every day. When you only exercise a couple times per week, it is much easier to turn one day off into three days off, a week off, or a month off.

If you are already used to exercising, switching to three or four times a week to fit your schedule may be preferable, but it is a lot harder to maintain a workout program you don’t do every day.

Be careful to not repeat the same exercise routine each day. If you do an intense ab workout one day, try switching it up to general cardio the next. You can also squeeze in a day of light walking to break up the intensity.

2. Duration Doesn’t Substitute for Intensity

Once you get into the habit of regular exercise, where do you go if you still aren’t reaching your goals? Most people will solve the problem by exercising for longer periods of time, turning forty-minute workouts into two hour stretches. Not only does this drain your time, but it doesn’t work particularly well.

One study shows that “exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat”[1].

This is great news for both your schedule and your levels of motivation. You’ll likely find it much easier to exercise for 30 minutes a day instead of an hour. In those 30 minutes, do your best to up the intensity to your appropriate edge to get the most out of the time.

3. Acknowledge Your Limits

Many people get frustrated when they plateau in their weight loss or muscle gaining goals as they’re learning how to get in shape. Everyone has an equilibrium and genetic set point where their body wants to remain. This doesn’t mean that you can’t achieve your fitness goals, but don’t be too hard on yourself if you are struggling to lose weight or put on muscle.

Acknowledging a set point doesn’t mean giving up, but it does mean realizing the obstacles you face.

Expect to hit a plateau in your own fitness results[2]. When you expect a plateau, you can manage around it so you can continue your progress at a more realistic rate. When expectations meet reality, you can avoid dietary crashes.

4. Eat Healthy, Not Just Food That Looks Healthy

Know what you eat. Don’t fuss over minutia like whether you’re getting enough Omega 3’s or tryptophan, but be aware of the big things. Look at the foods you eat regularly and figure out whether they are healthy or not. Don’t get fooled by the deceptively healthy snacks just pretending to be good for you.

The basic nutritional advice includes:

  • Eat unprocessed foods
  • Eat more veggies
  • Use meat as a side dish, not a main course
  • Eat whole grains, not refined grains[3]

Eat whole grains when you want to learn how to get in shape.

    5. Watch Out for Travel

    Don’t let a four-day holiday interfere with your attempts when you’re learning how to get in shape. I don’t mean that you need to follow your diet and exercise plan without any excursion, but when you are in the first few weeks, still forming habits, be careful that a week long break doesn’t terminate your progress.

    This is also true of schedule changes that leave you suddenly busy or make it difficult to exercise. Have a backup plan so you can be consistent, at least for the first month when you are forming habits.

    If travel is on your schedule and can’t be avoided, make an exercise plan before you go[4], and make sure to pack exercise clothes and an exercise mat as motivation to keep you on track.

    6. Start Slow

    Ever start an exercise plan by running ten miles and then puking your guts out? Maybe you aren’t that extreme, but burnout is common early on when learning how to get in shape. You have a lifetime to be healthy, so don’t try to go from couch potato to athletic superstar in a week.

    If you are starting a running regime, for example, run less than you can to start. Starting strength training? Work with less weight than you could theoretically lift. Increasing intensity and pushing yourself can come later when your body becomes comfortable with regular exercise.

    7. Be Careful When Choosing a Workout Partner

    Should you have a workout partner? That depends. Workout partners can help you stay motivated and make exercising more fun. But they can also stop you from reaching your goals.

    My suggestion would be to have a workout partner, but when you start to plateau (either in physical ability, weight loss/gain, or overall health) and you haven’t reached your goals, consider mixing things up a bit.

    If you plateau, you may need to make changes to continue improving. In this case it’s important to talk to your workout partner about the changes you want to make, and if they don’t seem motivated to continue, offer a thirty day break where you both try different activities.

    I notice that guys working out together tend to match strength after a brief adjustment phase. Even if both are trying to improve, something seems to stall improvement once they reach a certain point. I found that I was able to lift as much as 30-50% more after taking a short break from my regular workout partner.

    Final Thoughts

    Learning how to get in shape in as little as two weeks sounds daunting, but if you’re motivated and have the time and energy to devote to it, it’s certainly possible.

    Find an exercise routine that works for you, eat healthy, drink lots of water, and watch as the transformation begins.
