Thanks for sharing. I’m going to check that book out! 5 days is a lot 😅 most I’ve done is maybe 1.5-2days.
Day two is the hardest IMO. If you can do 48 you can do 72 or longer.
Phase 1: 0 to 4 hours– “Anabolic” phase, which is business as usual as your body breaks down nutrients from food and converts them into energy and body tissue.
Phase 2: 4 to 16 hours– “Catabolic” phase where you begin to metabolize body fat as energy and autophagy is activated.
Phase 3: 16 to 24 hours– Fat metabolism, autophagy, and the production of Human Growth Hormone all increase.
Phase 4: 24 to 72 hours– Increased production of ketones that fuel most cells in your body while BDNF increases to support brain function and neuroregeneration.
Phase 5: 72+ hours– The fat-burning, neuroprotective, and anti-aging benefits activated in the previous hours are enhanced.
