The Fasting Shake is part of our intermittent fasting product line. It's intended to be consumed during the fasting window. Additionally, the Fasting Shake is intentionally low in protein so as not to activate our body's nutrient-sensing pathways.
L-Protein is consumed during the feeding window. It provides calories and a high dose of protein (25g). It can be used as fuel after a workout, as part of a healthy breakfast or lunch when breaking your fast, or simply as a supplement to increase your overall protein intake each day.
