I used to play sports in school, but ran out of time in college. Then I had chronic Lyme for 10 years, and so I'm super happy to be regularly hiking. The best thing for me was to switch from an office job to being outdoors on my feet all day working with plants. I've done some workouts on and off, but I don't get the workout/runner highs that many people get so it's hard to be consistent. My metabolism also burns way too many calories already...
Recently came across Neuromovement therapy which is about training your brain to move the way it was designed, and to re-train the bad habits that we develop over the years (like being able to distinguish your vertebrae instead of 'blocking' your spine into 'neck' & 'high back/shoulders' & 'low back'). It brings amazing clarity & calmness to boot.
I want to underline that bolded part of your comment, wholly worth to read.
Why. I have never weighted more than 63kg and that happened when I was at my peak of 'athletism' in age of late teens. Doctors never measured any temperature when my own experience and other visible symptoms were clearly indicating 'high fever'. No matter what I ate, regardless of energy contention, only places on my body where that change could've been seen were a depth of cavity of my cheeks, and then only for those rare who knew me and meet me enough long to spot the difference. I always wondered how there can even exist multi-hundred kilos tanks of irresponsible eating for something that low than pleasure or comfort. I was and I still am very 'dry' guy by fat percentage.
With age I got "wiser" and more complex (metally particularly), and I realized that I was born with relatively rare genetic and physical complexion. Not even over two decades of extremely irregular and generally very unhealthy, changing life (both physically and psychologically) did chance the fact. My body temperature in rest is very low (~35.8 celcius degrees) and I avoid instinctively sweets and sugars, as my body doesn't ever make me feel that I need such things, and in those very rare occasions when it does really need more fast fuel, it doesn't have any impact to outlook of the ectomorph. Generally, mandatory amounts of minimum eating are always been automatically determined by the energy consumption I spent when doing something/anything in exact ratio to the reality. I have no culinary drive beyond the fact that I must eat. But oh'boy how I can enjoy when I get sometimes something really good...
For me this all is normal, but I can easily understand that this isn't the case with the majority of people browsing these threads.
Spartan body with spartan metabolism. Never going to be Mr. Universe, no matter what I do, or not to do, it simply doesn't make any difference. One of the "symptoms" is that I've been able to recover my basic level fitness easily within few weeks this far (42 yo currently), regardless of a state of being (100 book nerd on a sofa in few months, 100 bottles train-hobo with something to eat once in every 3 days, 10g/d skunking hippie, pathological HF rage-spammer...)
The point of the essay being that; do not only look to your outer measures and limits, look also what was set into your mostly genetically determined metabolism, what you need, and what you try achieve, but in sensible relation to a nature of your base metabolism. You can fight against your 'default settings' to some degree, highly more probably with lot more higher margin of success I ever could/can.
That is commented generally for all, not particularly directed to dear
