There are two phases of the digestive cycle, the anabolic and catabolic. During the anabolic, or building, phase, you eat, chew, digest, and absorb nutrients, which slows or halts the active process of detoxification that occurs most efficiently when the body’s not actively digesting food. When digestion stops, the body enters its catabolic phase, and detoxification immediately starts to rev up. As a result, people experience detox symptoms, which they interpret as hunger. They just have to eat again, they think, even though their body is already overfilled with calories. They can either eat frequently so their body doesn’t enter the catabolic phase for any sustained time, or they can eat calorically dense meals and animal products to keep the digestion (anabolic) process active until it’s time to eat again.
