Episode notes
Brown Fat Burns Dangerous Visceral Fat
- Brown fat is a mitochondria-rich tissue that burns visceral (harmful) white fat and raises metabolism.
- Foods like tomatoes, coffee, broccoli and certain polyphenols can activate brown fat without cold exposure.
Use Whole Foods To Activate Brown Fat
- Eat whole foods containing bioactives like lycopene and carotenoids to stimulate brown fat.
- Try a simple habit like one ripe tomato before a meal to reduce visceral fat and inflammation.
Feed Muscles Soon After Strength Work
- Prioritize protein soon after resistance training to support muscle growth and prevent breakdown.
- Avoid prolonged fasted training when pursuing hypertrophy; eat within about two hours post-exercise.
