Low water: dehydration
High water: mineral leaching
low calorie: metabolic downreg, semistarving
High calorie: SAD diet problems
low carb/High fat: overused glyco-genesis systems
High carb/Low Fat: constant clearing of toxic blood glyco
High protein: Rabbit starvation
High alcohol: constant clearing of toxic alco
So understand, you relieved your body of making its own glyco all the fricken time by adding in a little sugar when you where LC, this is what reduced your stress. lets say in six months time your metabolism starts playing up again (gettin stressed) so you add in more sugar to reduce stress, this time it might do nothing because the stress is coming from else where (like maybe low cal) and needs another antagonistic (opposite) response to reduce stress on your body.
sugar is not magic, it is not a panacea, it doesn't reduce stress, it is a chemical compound used by the body, if your body is getting to much or too little, its gunna get stressed, offering the antagonist to the "too low" or "too high" is what relieves this stress.
