But… remember what we mentioned above about eating real, high-quality foods for optimal health? Diet Coke may check a few of the keto boxes, but it doesn’t check the one we feel is the most important at Warrior Made: natural and nutrient-dense.</p> <p>Simply put, diet sodas like Diet Coke don’t add any nutritional value to your daily diet. You may be thinking, <i>I am OK with that. But, does it harm my health in any way?</i> We’re so glad you asked.</p> <p>If we dive into the nutrition label a bit further, we stumble upon a few hard to pronounce ingredients, <i>aspartame</i> being the standout. It’s always a good idea when reading nutrition labels to do a little research on the words we can’t even say.</p> <p>As it turns out, aspartame isn’t the safest ingredient. Learning a bit more about it may help you decide if diet soda belongs on the keto diet―or any diet for that matter.</p> <h3>Aspartame</h3> <p>Aspartame is an <i>artificial sweetener</i> that you find in diet sodas like Diet Coke and Diet Pepsi. It’s also a key ingredient in the popular sugar alternatives Equal and NutraSweet. These are all brands we know well and that have kept our sweet tooths happy. But, there’s some crazy science behind the substance they are comprised of!</p> <p>Aspartame is made up of <i>aspartic acid</i> and <i>phenylalanine</i>, which are both types of <i>amino acids</i>. Aspartic acid is produced naturally in the body, and phenylalanine is an <i>essential amino acid</i>, which means we get it from food. When digested in the body, aspartame converts to <i>methanol</i>, which is toxic is large doses<sup><a target="_blank" href="https://www.healthline.com/health/aspartame-side-effects#aspartame" rel="nofollow noreferrer">3</a></sup>. Methanol, when heated, can even turn into formaldehyde―a carcinogenic substance that has been shown to cause cancer in rats<sup><a target="_blank" href="https://www.cancer.org/cancer/cancer-causes/formaldehyde.html" rel="nofollow noreferrer">4</a></sup>.</p> <picture class="lazy-load"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/aspartame-diagram-chalkboard-0089.webp" type="image/webp"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/aspartame-diagram-chalkboard-0089.jpf" type="image/jpf"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/aspartame-diagram-chalkboard-0089.jpg"> <img src="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/aspartame-diagram-chalkboard-0089.jpg" class="img-fluid" alt="aspartame-diagram-chalkboard-0089"> </picture> <p>It turns out aspartame and diet soda can also contribute to health issues like:</p> <ul> <li>Seizures<sup><a target="_blank" href="http://www.diet-studies.com/open/Gaby2007-open.pdf" rel="nofollow noreferrer">5</a></sup></li> <li>Kidney Disease<sup><a target="_blank" href="https://www.kidney.org/news/kidneyCare/spring10/DietSoda" rel="nofollow noreferrer">6</a></sup></li> <li>Depression<sup><a target="_blank" href="https://www.newswise.com/ee/blog/entry/diet-soda-linked-to-depression-coffee-tied-to-lower-risk/" rel="nofollow noreferrer">7</a></sup></li> <li>Heart Problems<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3514985/" rel="nofollow noreferrer">8</a></sup></li> <li>Stroke and Dementia<sup><a target="_blank" href="https://www.ahajournals.org/doi/full/10.1161/STROKEAHA.116.016027" rel="nofollow noreferrer">9</a></sup></li> </ul> </section> <hr class="divider-50 divider-medium mx-auto"> <section> <section id="section3"> <h2>Diet Soda and Weight Loss</h2> <p>Ok, so you may be getting the picture that diet soda isn’t healthy. But, if you’re <i>still</i> not convinced, here’s another reason to think twice about it. Did you know that diet soda actually <i>prohibits</i> weight loss<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/29159583" rel="nofollow noreferrer">10</a></sup> ? We know―this is a bit confusing. How could a no-calorie, no-carb drink prevent you from losing weight?</p> <p>One reason is because it keeps your taste buds hungering for sweets! If you are drinking a lot of diet soda, its sweet taste will likely encourage the brain to crave other sweet treats. This creates a cycle where you end up eating more sugar than may be good for your weight loss plans.</p> <p>Diet soda can also mess with our weight loss plans because the sweet taste may trigger blood sugar to spike, and imbalanced insulin levels are a contributing factor to weight gain. The artificial sweeteners in diet soda also change our gut’s <a target="_blank" href="https://www.warriormade.com/content/diet/the-411-on-probiotics-and-the-microbiome/" rel="noreferrer">microbiome</a>, which may make us insulin-resistant and contribute to spiking blood sugar levels<sup><a target="_blank" href="https://www.healthline.com/nutrition/artificial-sweeteners-blood-sugar-insulin#section2" rel="noreferrer">11</a></sup>.</p> </section> <hr class="divider-50 divider-medium mx-auto"> <section> <section id="section4"> <h2>Diet Soda and Keto</h2> <p>We know answering this question is a little tricky. In theory, yes, diet soda fits the keto diet mold. And you may have even heard from what seem to be reputable sources like the FDA that artificial sweeteners like <i>saccharin, acesulfame, neotame</i>, and <i>sucralose</i> are safe to eat. But, if you’re looking to stay healthy and reach your body transformation goals, we recommend staying away from these sweeteners. They are made in labs and aren’t natural, which is the biggest reason we believe they don’t belong on keto… or any other diet for that matter.</p> </section> <hr class="divider-50 divider-medium mx-auto"> <section> <section id="section5"> <h2>There’s Hope for Your Sweet Tooth!</h2> <p>Ok, we know this article got a little gloomy as we laid out how bad diet soda can be for your health. But, let’s bring the sun back out, shall we?</p> <p>Removing diet soda from your diet doesn’t mean that you have to stop treating yourself to refreshing drinks or even to sweets. You’ll just need to do things a little differently. On keto we can use <a target="_blank" href="https://www.warriormade.com/content/diet/keto-sweeteners-which-ones-to-use-which-to-avoid/" rel="noreferrer">keto-friendly sweeteners</a> like <i>erythritol, stevia</i>, and <i>monk fruit</i> to sweeten our desserts and even our drinks! Below is a list of keto-friendly drinks you can add to your diet. You can sweeten them with the sweeteners we mention as they are natural and plant-based, don’t increase insulin levels, and are low-carb!</p> <picture class="lazy-load"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bulletproof-coffee-with-butter-on-table-0089.webp" type="image/webp"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bulletproof-coffee-with-butter-on-table-0089.jpf" type="image/jpf"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bulletproof-coffee-with-butter-on-table-0089.jpg"> <img src="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bulletproof-coffee-with-butter-on-table-LR-0089.jpg" class="img-fluid" alt="bulletproof-coffee-with-butter-on-table-0089"> </picture> <p>Keto-Friendly Drinks</p> <ul> <li>Coffee, or <a target="_blank" href="https://www.warriormade.com/content/diet/keto-butter-coffee/" rel="noreferrer">Keto Butter Coffee</a></li> <li>Iced or Hot Tea</li> <li><Keto Cocoa</li> <li><a target="_blank" href="https://www.warriormade.com/content/diet/hydration-how-much-water-should-you-be-drinking/" rel="noreferrer">Water</a></li> <li>Carbonated Water</li> <li><a target="_blank" href="https://www.warriormade.com/content/diet/keto-electrolytes/" rel="noreferrer">Electrolytes</a></li> <li>Alcohol (certain types, in moderation)</li> <li><a target="_blank" href="https://www.warriormade.com/content/diet/protein-powder-is-for-more-than-just-body-builders/" rel="noreferrer">Keto Protein Powder Smoothies</a></li> <li>Low-carb nut or alternative dairy drinks</li> <li>Zevia</li> </ul> </section> <hr class="divider-50 divider-medium mx-auto"> <section> <section id="section6"> <h2>Keeping it Real</h2> <p>So, does diet soda have a place on the keto diet? While some may disagree, our firm answer is no. We believe that the food you eat should be real. Natural, high quality, and nutrient-dense ingredients will help you reach your health goals better than ingredients made in a factory or lab. Artificial sweeteners like aspartame, which sweetens diet soda, doesn’t fit the bill. But don’t be discouraged. Sweets are still possible on keto.
