Your intestines typically hold about 1 to 2 pounds (0.5-1 kg) of stool at a time, though this varies greatly by diet, hydration, and regularity of bowel movements; however, claims of holding many pounds of impacted waste (like 8-40 lbs) are generally exaggerated marketing tactics, though severe constipation (fecal impaction) can involve significant buildup. The colon is designed to absorb water and process waste, with most of the weight being water, so significant weight loss from pooping is mostly water loss.

Chugging large volumes can cause significant nausea and discomfort, making it harder to finish the prep, so pacing yourself is key.
