Times change, as individuals we grow and develop. We explore new things, move on and come back.
For me, the last five years has seen a lot more awareness of myself. Putting on a bit of weight, then working to get rid of that again. Much of it came down to the numbers, and how they’re measured, recorded and exploited.
Weight, at it’s simplest level, is a question of energy consumed and how that compares to energy expended. Calories in vs Calories out. If we conume more than we expend, then the surplus remains as additional weight, stored as chemical energy. On the other hand, if we expend more than we consume, then we start to recover that stored chemical energy, and as a result lose weight. Those metrics are simple; bodymass, Basal metabolic rate in kilocalories, activity in kilocalories, and energy consumed as kilocalories. It’s not quite that simple, people have medical conditions that affect how energy and nutrients consumed are processed, but they’re not fundamentally changing the laws of physics.
This is where we get to the more interesting, to me, elements of quantification. How do we measure those energy types, and how much confidence do we have in them? And how accurae do we need to be? Weight is only one aspect of health, with how active we are and what that activity is being important as well.
I use a range of different tools, that I’ll mutter about in other articles, to guide my progress, nag me to develop one aspect or another about my health. I’m still a little heavier than I could be, but I’m in a very different place healthwise than I was five years ago. That’s in no small part down to the tools I’ve used to inform, and to help.
I’ll talk a little about the tools, and the running, cycling and swimming that have helped me get to where I am now.
