Although the Carnivore/Lion Diet often improves digestion for most people, there are some who experience constipation. The cause of constipation on the Lion Diet is usually experienced by those who have a severely damaged gut. The natural process of peristalsis (the involuntary contraction and relaxation of the muscles of the intestines or digestive canal, creating wave-like movements that push the contents of in canal forward) is no longer functioning due to the abuse done by overconsuming plant foods and processed foods. When this happens, it is best to increase your fat consumption to help things move along. As your digestive system heals, you won’t necessarily have to worry about eating high fat and will be able to eat leaner meats with no problem. Over time your digestion should improve and constipation vanishes.
Also, it is important to note that once on the Carnivore/Lion Diet, you won’t have as much waste (because your body is actually digesting/using what you eat) so expect less frequent and smaller bowel movements as well.
