Diet Soda & Artificial Sweeteners


Use with Caution, or Not At All

My Short History of Diet Soda Consumption

I have had several conversations recently on the topic of diet soda and artificial sweeteners and their impact on our health. This post is in response to those conversations. I should start by prefacing that I used to be a soda drinker, I admit it. In high school, it was part of my lunch and my breakfast. When I would get to school my first stop was the bookstore for a Bavarian cream filled, chocolate frosted donut and a 20oz Dr. Pepper. Looking back, it’s shocking what I ate times. Lunch was similar; fast food and a fountain—drink, often my poison of choice was another DP or Mountain Dew. I was never into the diet soda. It tasted off, funny, and gross to me. As I got older and into my twenties, college, work, life etc… I made the switch to diet coke with the belief that it was better for me, healthier, and would help slow or stop my weight gain. I was wrong on all accounts. I continued to balloon and my health continued to decrease little by little. At the peak, my Diet Coke consumption was a 44oz Diet Coke to start the day, which got me through my commute and to lunch; lunch included a refill, and that would generally get me to home; and at home, two liters were waiting in the fridge for a glass or two during the evening. On game day, Sunday, watching football I would be stocked up, and I would easily consume at least one two-liter while watching football. Sometimes more. I don’t recall drinking water much, it had no flavor or taste, but diet coke was “amazing.” Fast forward to 2018, I have rarely touched any soda in eight years. I don’t like it anymore, and I learned a lot along the way about how it affects the body.

Diet Soda’s Impact on Health

For 10 years, researchers followed diet-soda drinkers and non-diet-soda drinkers, their study showed that diet soda drinkers waist sizes grew 70% percent more than non-diet-soda drinkers, and that those who consumed at least two or more diet sodas per day had a 500% greater increase in waist size1. In 2015, they published their study of a dose-response relationship between consumption of diet soda and waist circumference1.  This is not to say that drinking regular soda full of high fructose corn syrup or cane sugar is healthy or does not lead to an increase in weight gain, it does, these impacts were observed as well; however, the point is that diet soda containing artificial sweeteners, such as aspartame and sucralose, had an increase in waist size and weight gain that surpassed those who consume sugary soda drinks. Why does waistline size matter?  Your waistline has a strong correlation to fat accumulation—particularly visceral fat, which is stored around the waistline. Visceral fat has been well documented to be a contributing factor to metabolic syndrome, type II diabetes, heart disease, and other negative health factors2,3.

Another way we are impacted by artificial sweeteners occurs in the brain by tampering with our food cravings and creates a negative cycle. A cycle that can be difficult for us to get out of. Artificial sweeteners are actually sweeter than real sugar. They have also been found to have addictive properties. They first alter our taste, so we prefer the artificial sweetener over real food, like fruits and vegetables, they even alter our perception and taste of real sugars. The sweeter foods can be more addictive than cocaine12,13 and artificial sweeteners are the sweetest.  Let’s review real quick, artificial sweeteners found in diet sodas and other processed foods have been found to increase our waist sizes—which leaves us prone to a host of health problems, and they can be addictive which means we will want more of them.

Studies have found that artificial sweeteners, while containing no calories for energy, still elicit a metabolic response 5,6,7. This can lead to mixed signals in the body which, in turn, leads to increased cravings and more hunger. Follow this path to its logical conclusion and we see an overconsumption of processed, high carbohydrate foods to satisfy the cravings these artificial sweeteners have induced.

Our bodies are complex, calories in versus calories out is a bit too simplistic. It overlooks look hormonal responses that food and environment have on our bodies. Diet sodas and processed foods that use artificial sweeteners are no exception. While as artificial sweeteners are often touted to be inert and have no effect on the body, the evidence is mounting that artificial sweeteners do have an effect, even if we do not fully understand all of the mechanisms just yet. While animal studies have shown insulin and glycemic responses to the consumption of artificial sweeteners, few human trials have replicated this finding and it not clear why just yet. One study did find a connection between insulin and blood glucose levels in a human trial using oral glucose tests that contained an artificial sweetener.4. This indicates to me that it’s a mixed bag of results at this time and more research is needed. We do know, that artificial sweeteners are addictive and have effects on our brain health as well 5,8. Artificial sweeteners have been linked to headaches, behavioral and cognitive problems, mood swings, anxiety and can impact our memory5,8,9. They signal dopamine response in the brain and they lead to increased cravings. Studies have also demonstrated that artificial sweeteners have a negative impact on our micro biome5,7. It alters the environment that also leads to an increase in appetite and cravings for sugary, high carbohydrate foods, as well as, influences hormones in the gut that aid in regulating insulin5,7.

Artificial sweeteners alter our cravings and the reward centers in the brain and gut that results in cravings for more sugary foods and simple carbohydrates5,7. With over-consumption, these sugary foods do have an impact on our blood sugar and insulin sensitivity over time which leads to chronic illness. We also are now seeing studies show that chronic consumption of artificial sweeteners can also impact our glucose sensitivity over time.6,10

Conclusion

The health risks far outweigh the rewards when consuming artificial sweeteners in our food and drinks, and diet sodas should be eliminated from a healthy lifestyle. Artificial sweeteners have been linked to obesity and an increased risk of heart disease, type II diabetes, stroke, obesity, dementia, anxiety, headache, and cancer2.

The image to the right is what we are sold by advertisers and food manufacturers.  “lookYoung beautiful girl Drinking a Bottle of Green Juice with Straw blue sky, holding a glass of smoothie, detox, healthy food, fruit cocktail outdoor portrait,close up,tasty,smiling enjoy her weekends good, skinny and enjoy the sweetness of a calorie-free food.” The image is far from the truth. Some may stay thin, more will add to their waistline, and most of us, visible or not, will have adverse health effects in our microbiome, which is a vital and complex system in our body. 

While many people opt for low calorie and zero calorie foods, snacks, and beverages under the impression they are improving their health by reducing their calorie intake and fat intake, they are making matters worse by consuming food like products and drinks. There is a common belief that if it is in our food system it must be safe for consumption. To fully explore that statement is another lengthy article on its own, and one we hope to take on in future. The main take away is this: Food-like products are just that, food-like, they are not real food. Most artificial sweeteners on the market are fully synthetic, and even the much-touted Splenda, a “healthier alternative” to aspartame products, has many similar negative health effects when consumed. The best approach to health and wellness is one that revolves around real food, whole food, in conjunction with a healthy lifestyle — not one full of quick shortcuts that in the long run short change us.

My Story Part 1

Today  2018
300 Pounds
The Old Me in 2010

When I first started my journey back to what I call “healthy” I started from a place that seemed too far to travel back from. I was wrong, dead wrong. My journey back to health began in 2010. As I neared by 30th birthday I had taken a quick trip to San Diego with friends from college. Digital cameras were the thing, take a photo, use the viewfinder screen to review your new photo and no waiting for the film to develop. On that trip, I saw photos of me taken earlier that day and it deflated me. I honestly think I may have ruined the trip for the other three who were there because my mood changed from “on vacation!” to “WTH!” What I saw I didn’t recognize. It was a very large overweight 29-year old that looked miserable inside. I was miserable, I was depressed, lost and obese by any measurement, I didn’t know I had gotten so big. Or perhaps I did and I just not to see it. I knew before the trip to San Diego that I was not thin or fit and had a few pounds to lose. In fact, I had attempted many times to lose weight for a decade prior to this trip. I tried it all, the lemonade detox, zone, beach body, starving, low fat, no fat, you name it. I lost some weight on all of them and gained it all back and a little extra for good measure. In the course of my journey, I injected my self with hormones (I tried testosterone and the HCG diet), I restricted my diet to a handful of foods, suffered and gave up multiple times until I decided to educate myself. At my largest point, I was tipping the scales at just over 300 pounds, squeezing into a 44″ pant, looking for clothes at a big and tall store because most stores around me only went to XXL and 42″ waists. I was written prescriptions for high blood pressure and statins for high cholesterol and told by my doctor that I would not likely see my 40th birthday if I did not change. The doctor’s visit came about a month after the trip to San Diego, when I determined I needed a physical because the home DVD warm-up for the work out almost killed me and I felt I needed a doctor. That trip to the doctor showed  I had all of the bad biomarkers, extremely high triglycerides, low HDL levels, hypertension.  I never started the prescriptions that were given to me. It felt odd having those slips of paper handed to me, it seemed wrong, “eat better” and “take these” was not enough for me. Now I had questions, lots of questions. What does “eat better” really mean? Seriously, is there a more confusing and nebulous term? I spent the next year losing some weight about 40 pounds while I was starting to learn and find my way through what it meant to restore my health. I moved back to my home state, ended a long-term relationship, found people who could really help me navigate this journey and joined a gym that gave me anxiety. How a gym gave me anxiety will be

another part of this blog post series, but in short, the first time I went to the gym, I walked out, I was too embarrassed by my size to stay.  I learned that restoring my health was not something that I could just do. I tried that for a decade and failed every time by every measure of the word failure. Fast forward to today, 2018, I have a family, friends, eight years worth of reading, studying, applying and learning about health. I maintain a healthy life, it is not hard or stressful to do this either, it is natural. I average 12% body fat, I weigh 190 pounds and I am an active father, husband, business owner and a curious person who keeps growing and learning. I did not do this journey alone, I met a lot of wonderful, smart people along the way. Some of them have joined me here at Bison Health Coaching where they continue to inspire others. I am grateful for them, I am grateful for what I have, my life back. Here is what I can tell you, it is about more than just what and when you eat, or how much you workout. It is about how you do everything. Don’t let that sound daunting, it’s not when you have a coach that can help you navigate the way and empower you to make the changes needed. I learned what is really required to make lifelong lasting, healthy changes. The first step is knowing you want to make a change, the second is asking for the help to make the change. I will be posting more about my journey back, the mistakes I made, and how I have managed to not return to the 300-pound version of myself. If you want to make the change if you want to know what it feels like to be the best you then I encourage you to reach out to us on our contact page and start taking your health to the next level.
