Fasting for different lengths of time affects how fast your body burns energy, and fasting too often can slow it down instead of speeding it up.
Scientific Claim
Prolonged or frequent fasting can cause a decrease in metabolic rate after an initial increase.
Original Statement
“When you compare 12-hour fasts, 24-hour fasts, 36-hour fasts, 72-hour fasts, you can actually see where 168 goes wrong and why it eventually slows down the very metabolism that you're really trying to speed up.”
