HOW DOES YOUR BODY ACTUALLY BURN FAT....ITS A PROCESS. 👇
Fat loss isn't just about calories in versus calories out—it's a sophisticated biochemical process happening at the cellular level👇👇👇
1️⃣ FAT MOBILIZATION
Fat mobilization is the process of releasing stored fat from adipose tissue into your bloodstream:
• Triggered by hormones like epinephrine and norepinephrine (catecholamines)
• These hormones activate an enzyme called hormone-sensitive lipase (HSL)
• HSL breaks down triglycerides in fat cells into free fatty acids and glycerol
• The free fatty acids enter the bloodstream bound to albumin for transport
🔷️Key point: LOW INSULIN levels are critical for optimal fat mobilization. When insulin is elevated, HSL is inhibited, reducing fat release.
2️⃣ FAT OXIDATION
Once mobilized, those fatty acids must be oxidized (burned) for energy:
• Free fatty acids enter muscle and other cells
• They're transported into mitochondria via carnitine palmitoyltransferase-1 (CPT-1)
• Inside mitochondria, beta-oxidation breaks fatty acids into acetyl-CoA
• Acetyl-CoA enters the Krebs cycle, producing ATP (energy)
🔷️Key point: Your metabolic flexibility—how efficiently your body switches between burning carbs and fats—determines fat oxidation capacity.
MAXIMIZE YOUR FAT LOSS👇👇
For optimal fat burning, you need both mobilization AND oxidation working efficiently:
• Morning fasted training: Low insulin environment promotes mobilization
• Zone 2 cardio (moderate intensity): Maximizes fat oxidation rates
• Cold exposure: Activates brown adipose tissue for enhanced thermogenesis
• Sleep optimization: Maintains hormonal balance favoring fat metabolism
• Strength training: Increases mitochondrial density and metabolic rate
Remember: You can mobilize all the fat you want, but if oxidation capacity is limited, those fatty acids may just return to storage.
Live Long, Be Strong 💪💪
