Are you wondering whether your body is burning fat or muscle for fuel? In this episode, Kylee Arnold breaks down the science behind fuel sources, how your body prioritizes survival over aesthetic goals, and what you can do to ensure you're losing fat, not muscle. Plus, learn the key blood markers and metabolic pathways to watch out for.Key topics:

• The four main fuel sources: glucose, fatty acids, ketones, and amino acids
• Why your body favors survival mechanisms like gluconeogenesis over fat loss
• Differences between gluconeogenesis and ketosis, and how they impact muscle preservation
• The roles of AMPK and mTOR pathways in fat loss and muscle building
• How stress, diet, and lifestyle influence metabolic pathways and fat loss success
• Blood markers to assess metabolic state: ferritin, fasting glucose, ...
