Protein
During a period of fasting, the body first uses stored glycogen from the liver and muscles as a source of energy. Once the glycogen stores are depleted, the body starts breaking down fat reserves to produce energy through a process called lipolysis.
When fasting or on a very low-calorie diet, the body initially breaks down glycogen stores in the liver and muscles for energy. Once glycogen is depleted, the body starts to rely on stored fat for fuel through a process called lipolysis.

Ketones
Yes, when glycogen stores are depleted during fasting, the body will start breaking down body proteins, such as muscle tissue, to synthesize glucose through a process called gluconeogenesis. This allows the body to maintain blood glucose levels for energy production. However, the body will prioritize using fatty acids for energy before breaking down body proteins.
When your body needs energy, it will first use carbohydrates stored in your body, sparing the protein and fats in your body. When the stored carbohydrates are depleted, the body will start using protein and fats.
From stored fats
Fasting can increase the body's ability to metabolize alcohol more quickly. This is because when you fast, your body uses up its stored glycogen, which can help speed up the breakdown of alcohol in the liver. As a result, fasting can lead to a faster elimination of alcohol from the body.
During aerobic exercise, the body primarily uses carbohydrates and fats as fuel sources rather than protein. While protein can be utilized for energy, it is typically reserved for situations of prolonged fasting or extreme exercise when glycogen stores are depleted. In general, the body prefers to preserve protein for muscle repair and growth rather than burning it for energy during aerobic activities.
