Plateaus are something to push against. They help you climb up to the next level. It is a resting spot to help your body adjust. They do not last forever.
My husband did morning PT for 20 years in the Marine Corp. Now he hates morning workouts. He likes to go to the gym after work. He does a few minutes of cardio and then hits the weights hard. It relieves the stress of his day.
Those shakes act like the rubber band in a sling shot flinging you past the hard part of adjusting to low carb and move you past poor planning and suprise situations. Amazing.
