this actually makes total sense based on your hormones. the two weeks leading into your period are the luteal phase, where estrogen is rising. a quick summary of some of the changes that happen: decrease in blood plasma volume means less water in the blood, which increases your risk for hyponatremia (dehydration), and results in an increase in core body temperature. most importantly, your body spares carbohydrates, meaning that it won't use them as easily for fuel, and makes it harder to hit higher intensities. the best way to deal with this is to increase carbohydrate intake, make sure you are drinking enough (don't rely just on thirst), and slightly increase sodium intake
So... Can we talk about this? If armed with enough information I should be able to figure this out and calendar my food and water month, right? I have a Garmin smart scale and I know my cycle.
Today my scale told me:
Body fat 27.8%
Body water 52.7%
Skeletal muscle mass 51.4
Bone mass 7.0
FYI race weight is 145....
I'm on day 17 of a 28 day cycle
Ok. I admit. I don't know where to go from here. But this is the "not hungry" week that I have every month. Next week I'll eat everything in sight. The flow week will be angry tummy. The week after I am chasing salts and carbs. I have an app that I track all this in. I'm hitting around 9 hours of training a week, I peak at around 12 hours and rest weeks are around 6 hours.
How do I figure myself out? Keep in mind I'm a f/mop, no coach, used TT bike that is... aged, my cleats are 14 years old, and I stop and smell the flowers sometimes. Been at Tri on and off for 25 years (more on than off). But, I'm an exceptionally healthy eater. Where do I start if I want to dial in nutrition and routine? Especially during the "eat everything in sight" week?
