Riding is much more fun, but I suspect you are completely right about walking being the better choice for weight loss. I was at my leanest when my breakfast was just black coffee and it was followed by a 60-90 minute walk.
The great thing about walking is that you can just keep doing it mindlessly, while also doing other things such as commuting, shopping, running errands and taking care of the dogs, which you need to do anyway. The inefficiency, compared to running, is more than offset by the fact that it's so much easier to find an opportunity to walk.
Ive started doing 6kmh walk for 30min after gym, two times a week and Ive lost like 10kg in 6 months
"Load carriage" is a thing the military has put some effort into studying. A 50lb pack turns a brisk walk into something that burns 100s of calories. Even an extra 20lbs on your back adds up. It might not feel like a lot, but the difference in heart rate for same perceived effort is shocking.
I can ruck a 20lb pack for 20 miles a day for weeks, but even that took a lot of training. Doing that with 50lb feels like it would be impossible. Maybe my 135# body has some limiting factor.
That being said, I love taking out a 50lb pack just to clear my head. It's like forced meditation.
Slow down a bit to 4-5km/h and you can last much longer, not to mention multitask more effectively (listen to an audiobook, be on a phone call, just brainstorm, etc.) so you don't actually need to set aside hours a day specifically for walking.
It is kind of nothing if you live "the old school way", that amount of walking just accumulates. If you live "the post covid way" or "car with close parking lot way", then it becomes large block of time you have to carve separately.
It sounds plausible that the amount of hunger we feel when we feel a fixed number of calories may depend on how much that depleted our glycogen stores, among other factors.
The vast majority of middle-aged people who exercise at all, do only one thing.
You do you, but it's a bit like somebody consuming only large amounts of meat and somebody suggesting that it may be beneficial to reduce some of that and balance the diet with some other nutrients.
Health isn't my goal, it's a second-order effect. I just know that you can achieve top 1% fitness without the time-consuming yoga and gym routines.
Last year, I mostly switched from a road bike to a gravel bike and found the lowest gear far more comfortable for steep hills because the lowest speed was about half.
* I actually can't remember the exact speeds, but I think it was about 5mph / 8km/h on the road bike and roughly about 5km/h on the gravel bike.
