The crash after the high has a mechanism
Glucose gives the cell fuel. Fructose, through the enzyme fructokinase, pulls a phosphate from ATP and leaves uric acid behind. Research associates that sequence with mitochondria shifting into a lower-output state, which Chris describes as an energy debt. A cell running short sends a signal for more food, and the craving loop starts. Both halves of table sugar show up in the same bite, which may be why the high and the crash travel together.
