The nervous system, including the brain and spinal cord, governs everything related to fat loss, yet its role has been overlooked in discussions about losing fat.

Adrenaline, released from neurons connected to fat, plays a crucial role in fat oxidation, meaning the burning of fat is influenced by local neuronal activity rather than just systemic adrenaline from stress or fasting.

The principles of fat loss are linked to how we engage the nervous system and the patterns of exercise we choose, as high-intensity exercise triggers significant adrenaline release, which is crucial for fat thermogenesis and oxidation, while low to moderate-intensity exercise does not stimulate adrenaline as effectively.

The gut has neurons that respond to nutrients, signaling the brain when essential amino acids are consumed, which is crucial for understanding hunger and satisfaction.

Neurons in the intestines, such as GLP1R neurons, detect stretch and nutrient presence, sending signals to the brain to regulate eating behavior based on gut status.

The gut communicates with the brain through mechanical and chemical signals, influencing hunger and satiety based on the fullness or emptiness of the stomach and intestines.

The nervous system governs muscle movement through the relationship between neurons and muscles.

Our nervous system includes the brain, spinal cord, and peripheral nervous system, which connects to every organ in our body, influencing our mental states.

Incorporating non-exercise activities like fidgeting and shivering can significantly increase caloric burn and enhance fat loss through increased thermogenesis.
