The main purpose of getting into ketosis and becoming a fat burner is to induce weight loss and promote natural appetite suppression, although there are other health benefits as well.</p> </section> <hr class="divider-50 divider-medium mx-auto"> <section id="section4"> <h2>Keto Diet Pros and Cons</h2> <p>Many people first discover the keto diet when they are trying to find the best diet to lose weight. Although keto is effective for weight loss, it has many other potential benefits <sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/12430970" rel="nofollow noreferrer">9</a></sup>. Here are a few of the highlights:</p> <ul> <li><strong>Appetite reduction</strong>. Due to the impact that keto has on appetite regulating hormones and the increased protein intake of the diet, it seems to naturally suppress appetite and calorie intake with little effort<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/17228046" rel="nofollow noreferrer">10</a></sup>.</li> <li><strong>Improved cholesterol and triglycerides</strong>. The keto diet lowers blood fats called triglycerides, increases levels of “good” HDL cholesterol, and decreases bad cholesterol(<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/16424116" rel="nofollow noreferrer">11</a>,<a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/19439458" rel="nofollow noreferrer">12</a></sup>).</li> <li><strong>Decreased abdominal fat</strong>. Fat in the stomach area may be a sign of insulin resistance and increased inflammation. The keto diet helps people lose excess abdominal fat more than other diets(<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pubmed/15533250" rel="nofollow noreferrer">13</a>,<a target="_blank" href="https://onlinelibrary.wiley.com/doi/full/10.1038/oby.2006.277" rel="nofollow noreferrer">14</a></sup>).</li> <li><strong>Reduces blood sugar and insulin</strong>. Cutting back on carbs significantly improves blood sugar and insulin needs(<sup><a target="_blank" href="https://nutritionandmetabolism.biomedcentral.com/articles/10.1186/1743-7075-2-34" rel="nofollow noreferrer">15</a></sup>). </li> <li><strong>Helps improve brain function</strong>. The ketogenic diet may protect the brain against age-related decline(<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2367001/" rel="nofollow noreferrer">16</a></sup>). </li> </ul> <p>Although the keto diet has many benefits, there are also a few drawbacks. </p> <p>The keto diet, due to a lower intake of <a target="_blank" href="https://www.warriormade.com/content/diet/keto-fiber-foods-5-fiber-rich-foods-to-add/" rel="noreferrer">high fiber foods</a>, may not meet the daily fiber requirement of 25-35 grams per day, unless your diet is well balanced. There is some concern that this may negatively impact gut bacteria, who love to eat fiber, in the long run <sup><a target="_blank" href="https://www.sciencedirect.com/science/article/abs/pii/S0920121118301578" rel="nofollow noreferrer">17</a></sup>. </p> <p>The first week or two on the keto diet you may also experience the “keto flu”. These are the symptoms of your body moving into ketosis which include headaches, fatigue, and nausea<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2633336/" rel="nofollow noreferrer">18</a></sup>. But, this usually resolves once you fully move into ketosis.</p> <p>The ketogenic diet is quite restrictive. It can be difficult to sustain long-term, since it eliminates many different food groups.</p> <picture class="lazy-load"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/paleo-vs-keto-weight-loss-0055.webp" type="image/webp"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/paleo-vs-keto-weight-loss-0055.jp2" type="image/jpf"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/paleo-vs-keto-weight-loss-0055.jpg"> <img src="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/paleo-vs-keto-weight-loss-LR-0055.jpg" class="img-fluid" alt="paleo-vs-keto-weight-loss"> </picture> </section> <hr class="divider-50 divider-medium mx-auto"> <section id="section5"> <h2>Do You Lose Weight Faster on Paleo or Keto?</h2> <p>You could lose weight on both diets since they eliminate many of the same foods. </p> <p>There are several short-term studies showing that both diets could be effective for weight loss.
