How Long Does It Take For Your Body To Start Burning Fat Instead Of Sugar?

Have you ever wondered whether the body prioritizes burning sugar or fat for energy? Well, the body is capable of utilizing both sugar and fat as energy sources, but it tends to preferentially use sugar due to its quicker and more straightforward conversion into energy. Nevertheless, it’s crucial to note that the body’s sugar reserves, stored as glycogen, are limited. This limitation is where the concept of fasted cardio becomes relevant. During fasted cardio, typically performed in the morning before eating, the body taps into its fat stores for energy since glycogen levels are lower after an overnight fast. This process can aid in weight loss and fat burning. (Date: September 19, 2023)

The process of your body transitioning from utilizing the energy derived from the last meal you consumed to burning stored fat typically begins approximately eight to 12 hours after your last meal. You might wonder why this transition doesn’t happen sooner. To delve into this, it’s important to understand that the body primarily relies on the immediate energy from the food you eat. After a meal, your body spends time digesting and absorbing nutrients. Once this initial phase is complete, usually within the aforementioned time frame, your body gradually shifts to tapping into its fat reserves as an energy source. This transition period allows your body to access stored fat effectively for sustained energy, making it a crucial aspect of weight management and fasting strategies.

Many people wonder about the process of transitioning from relying on sugar as the primary source of energy to effectively utilizing fat for energy. This transition is commonly referred to as switching from sugar burning to fat burning. So, you might be wondering, “How can I make this switch?” The answer is straightforward: reduce your carbohydrate intake. As a weight-loss specialist, one of my initial recommendations to patients is to eliminate grains and sugar from their diets. This step is crucial for initiating the shift towards fat burning.
