The purpose of the glycerin in the L-Drink is to provide the body with an alternate energy source to use instead of breaking down lean body mass during days 2-5 of the 5-day program. Essentially, the L-Drink helps protect your lean body mass while keeping you in a fasting state.
You will use the amount of L-Drink associated with your weight and mix it with 28-32 ounces of water to sip throughout your day. The weight on the L-drink is marked from top to bottom, meaning the more you weigh, the more L-drink you will have to pour.
If you do not wish to use the L-Drink, skipping it should not impact your results negatively, but it may impact your overall experience and energy level or put you at a slightly higher risk of losing muscle.
The L-Drink is intended to be consumed during the 5-day program only. Glycerin is not metabolized by the body when you are in a non-fasted state; it is excreted. In a fasted state, glycerine is able to enter the Kreb's cycle to produce energy and protect muscle. It also helps account for people with different body weights participating in the 5-day program. Since it is excreted in a non-fasting state, we do not recommend consuming the L-Drink outside of the 5 day program. Please discard after one use.
