Yesterday, J decided to have a coffee-fast day. I did a simple high-fat day which, when i entered it into FitDay last night, turned out to be very low in protein -- less than 40 grams -- though the energy consumed (1700 kcal) was within what i consider a reasonable range.
I woke up this morning cold and hungry. We know what that means! SOMEthing about yesterday's menu was severely inhibitive of thyroid function ... and my body wasn't properly satiated (though my stomach was) with what it received. I think the lack of protein nourishment answers both questions.
Although i BELIEVE i took in enough energy to keep my body from slipping into conservation-mode, i may be mistaken. During my periods of being able to follow the Strong Medicine protocol last year, i wasn't consuming a VERY different amount of energy. It seemed that i was losing WELL on about 1 g. protein per pound of LEAN tissue (which is not the same as 1g/lb. WEIGHT), and a not-extremely-different proportion of protein to fat (23:77% by kcal).
So today, i'm increasing my protein intake and trying to keep my fat intake high, as well. (Time to try out another dessert or beverage recipe from FFcookbook!) ...It sure would be easier to tweak diet for well-being and fat-loss if all these systems weren't so entangled! ;-)
