With the increasing popularity of fasting and ketogenic diets, many people are looking for effective ways to achieve ketosis. Fasting has emerged as a popular method to accelerate the transition into fasting ketosis, offering numerous health benefits.
In this post, we will explore the science of ketosis, the benefits of achieving ketosis, the role of fasting in ketosis, factors influencing the transition, and practical strategies to propel yourself into ketosis faster.
FASTING KETOSIS TIMELINE
| 12 hours of fasting | Flipping the Metabolic Switch | During this phase, your body is no longer using stored carbohydrates for energy. Instead, your body starts to release stored fats to be converted into usable energy. This "switch" typically begins around 12 hours, but your body will continue to use alternate sources of fuel, such as fat, throughout the prolonged fasting period. |
| 72 - 120 hours of fasting | Insulin and Glucose Significantly Decrease | Fasting for 3 or more days has shown to reduce circulating insulin and glucose by about 30%, in some cases even more, which can help reduce risk for metabolic disease, such as diabetes. |
| 96 - 168 hours of fasting | Fat as Fuel | Although ketosis has begun earlier in the fasting phase, your body is now fully dependent on using ketone bodies and free fatty acids to produce fuel for the brain and the muscles. Around day 4, there is a dramatic increase of ketone production, which continues to rise up to (and past) day 7. |
Understanding Ketosis
Ketosis occurs when the body shifts its primary energy source from glucose to fat. It is a natural metabolic state that is achieved by following a low-carbohydrate, high-fat, and moderate protein keto diet. When the body is in ketosis, it efficiently burns fat for fuel, resulting in weight loss and improved metabolic health.
This process can lead to reduced blood pressure and improved insulin sensitivity, making it beneficial for individuals with cardiovascular disease or high blood pressure. Ketosis can also enhance the immune system and reduce oxidative stress.
The Science Behind Ketosis
In the state of ketosis, the body shifts its primary energy source to fat stores, induced by a low carbohydrate intake. This metabolic state leads to an increased production of ketones while requiring restriction of glucose levels.
Encouraged by the keto diet, ketosis promotes the utilization of fat for energy, benefiting areas such as blood pressure and the immune system. By focusing on healthy foods, such as olive oil and whole grains, and reducing the consumption of sugars, individuals can maintain ketosis long-term, minimizing the risk of cardiovascular disease and oxidative stress.
Benefits of Being in Ketosis
Achieving ketosis offers various advantages, including weight loss and enhanced body composition. The state of ketosis can assist in regulating blood sugar levels, leading to improved cognitive health and reducing the risk factors for heart disease.
Additionally, it may contribute to better metabolic health, making it a viable option for individuals looking to improve their overall well-being. These benefits make the keto diet a compelling choice for those seeking a balanced diet and long-term health improvements.
