Our Fasting Shake is part of our intermittent fasting product line. It is intended to be consumed during your fasting window, as it will not break your fast or affect your ketone levels during time restricted feeding (TRF). Additionally, the Fasting Shake is also intentionally low in protein to stay below our body’s nutrient sensing pathways. L-Protein is consumed when you are eating food. It provides calories and a high dose of protein. It can be used as fuel post workout, as part of a healthy breakfast or lunch when you do break your fast, or it can simply be used as a supplement to increase your overall protein intake each day.
