@rosenstein if the liver can’t store glycogen then sleep will be affected, (no fuel during sleep-which ironically is a metabolically demanding process). Stress in the form of overtraining will raise cortisol which can lead to fatty liver and decreased glycogen storage/muscle catabolism. Some of us with favorable body composition might be able to skirt this for a time because muscles can store glycogen too, (my personal theory is that they do so when subjected to the stress of training as localized glycogen storage tanks to deal with stress more immediately-especially if liver function is impaired).
I don’t do the caffeine before bed, (sorry for any confusion there). I take my last dose around 3pm. My reasoning for the caffeine and vitamin K supplementation is due to a number of studies Haidut posted on the old forum regarding their leaning out the liver and assisting in glycogen storage. When I started “Peating” I couldn’t drink black coffee without cold hands and feet. Now I can drink a double espresso on an empty stomach with no stress response, (suggesting my glycogen storage is much improved).
In the studies, I believe glycogen storage was improved with a certain amount of caffeine mg/kg. In my initial experiments I used 1200mg split in three doses of 400mg each with lots of food for two weeks. Since then I’ve found I prefer 200mg twice a day for longer periods. This also assisted in improved metabolism as I dropped body fat while increasing calories and maintaining training regime. My weight went from about 235 to 205, (and the weight loss wasn’t instant, it continued after ceasing the caffeine over the course of the next few months).
K in studies was found to lower liver enzymes dramatically at 15mg over a few weeks, or 45mg over a few days.
