Correct, Low intensity steady state cardio (LISS) can and is just as effective for most people. As you said though, when you (always) do it, it’s still great, but kinda becomes not exercise but just your normal activity. Still awesome and shouldn’t be pulled for sure. I wouldn’t fall into that trap of being worried about Cortisol, I know that’s a popular thing to do and blame everything on when it comes to keto’rs. Know what else Cortisol does? Gives you great energy, makes you feel happy and amazing! Wakes you up in the morning, Makes you alert, makes you make split second decisions easier, improves hand to eye coordination. See where I’m going with this? Cortisol is much more your friend than it is your enemy, when it’s chronically high for no reason, ya, that’s not good either. But there’s a good spot for everything.
Same goes with Insulin, people completely obsess about a hormone they can’t even check without a lab, ok, it can stick fat in cells, great, it also delivers nutrients and all the good stuff to them as well which is why in bodybuilding even those managing sugar and carbs during a cut still want post workout carbs to drive in all the nutrition post workout. Same deal, it’s all about the context.
I wouldn’t recommend starting up with CrossFit or anything (wouldn’t to a 30yo either!) but screw that, age is a number! Our biological age is far more important than our chronological age. You sure as hell don’t look 70 dude! I’d argue that you shouldn’t either! We’re so accustomed to people giving up at young ages and wasting away that we now have these (incorrect) mental ideas of what a 40-50-60-70yo person should look and act like. NOT THIS GUY!
I love the saying and sadly forget who said it, “I’m going to dye young, at a very old age”.
Stuff like that will add up very quickly, even a couple tbsp in a large drink can throw 200+ cals on your day like it’s nothing. I switched to light cream a long time ago, not a huge difference, but that 20 cals saved per tbsp, over the course of half a dozen iced coffees a day in my case adds up really fast. I capped my fat at around 80g, If I go over I go over, but try to replace that with protein.
Your call, but without it you’re left guessing everytime something doesn’t work. Use an app and it becomes second nature and literally take a minute before meals. Tracking is what undid over a year of hell for me, allowed me to fix my metabolism, and recomp at a pretty crazy level. Last time I was 225lbs I my bodyfat was in the high 20’s-low 30’s, now I’m 225 at around 10%. I didn’t do that as a true recomp, I lost a lot then put the muscle back on, but tracking and watching everything was the only way I was able to do that without getting fat again. It’s also how I learned that I had to watch fat and salt intake, keto wasn’t saving me from that. Salt in higher amounts turns me into a water balloon, and when my fat starts passing 100g, I won’t lose bodyfat no matter what else is dialed in perfect. Gotta have numbers to work with to figure things out!
