Fasted Lifting. in The Napkin.

My experimenting continues.

Over fifteen years ago, I educated myself in The Way of the Rat.

Okay, close enough.

Part of my self-education in How to Move Inanimate Objects was nutrition. Namely preworkout nutrition, and postworkout nutrition. It’s… kind of self-explanatory. Eat beforehand. Eat afterwards. Pretty simple. Fuel your workout, then fuel your recovery.
(Though, the PWO window isn’t some strict OMG, JUST FINISHED MY LAST SET, GOTTA DOWN MY WHEY. )

Whenever I bother doing cardio, it’s generally fasted. Years ago, I would hop out of bed and be outside for a jog in under ten minutes. Time aside, who wants just swallowed food sloshing around in their gut? And if I have a date with the dreadmill, I still just head to the gym fasted to save time. While it doesn’t actually effect total caloric burn either way, if you’re trying to drop weight, there’s something psychologically weird about eating and then hitting the dreadmill.

Anyway. I’ve done enough fasted cardio that I know I feel fine during and after. No particular difference in performance. Hey, I always say I hate cardio - it’s not like I’m some track star kicking it to 6 mph. I’m lucky if I can hold 4.5 mph for longer than two minutes.

So, out of curiosity, I did my lifting session today without breakfast prior. Performance? All lifts improved roughly at the same pace I’ve come to expect. Was slightly “eh, I COULD eat” before, but felt fine after. Exercise suppresses my appetite.

(My hunch is it has to do with the sympathetic vs parasympathetic nervous systems. Such a thing as being too busy to eat. Whereas if you’re sitting on the couch “resting” you might also find a desire to be “digesting”. [You know. Parasympathetic is “rest and digest”. You learned it in A&P like I did, right?])

I had 6 eggs when I got home. By not eating breakfast, I was able to go a little heavier, rather than overrationing calories. Which means less of a risk of needing a middle meal between then and dinner. Which means I can go heavier on dinner and still stay on target.

(Oh, dinner will be chicken, brussel sprouts, and green beans. Might toss in a can of rotel into the casserole pan for flavor, unless I stick with just EVOO and rosemary.)

So. Same performance. Same calories for the day. Easier hunger management or lack thereof. Huh.

Requires more data. : )
