1. Place an ice pack on the back of the neck or upper trapezius area for 20–30 minutes, preferably in the evening, when insulin sensitivity is lowest. I place a towel on the couch while writing or watching a movie and simply lean back against the ice pack. 2. Consume, as Ray did, at least 500 milliliters of ice water on an empty stomach immediately upon waking. In at least two studies, this water consumption has been shown to increase resting metabolic rate 24–30%, peaking at 40–60 minutes post-consumption, though one study demonstrated a lower effect of 4.5%.
