>You do not need to even weigh yourself

If you have your accurate TDEE, sure. But even that changes as you lose weight, as gain muscle or even with diet.

But I assume most people aren't doing calorimetry exams to know their accurate TDEE. Imagine you try to calc TDEE on one of those sites and it gives you a wildly inaccurate estimate, and you work off of that, if you weren't weighting yourself you wouldn't even know that.

What you can do is to reverse engineer, like if you know that you're eating at maintenance, track your daily calories for a week, average it out and that's probably your TDEE. But then again, that requires you being at maintenance, i.e, going on a scale to know you're not gaining or losing weight. (you can technically reverse engineer even if you're gaining or losing, for example, if you're losing 0.2g/day, *7500 that's 1500 kcal deficit, if you're eating 1000 kcal daily then your TDEE is 2500 kcal, but again, that's also inaccurate since you won't consistently lose 0.2g everyday, it fluctuates)

Even 5 miles = 500kcal varies wildly, with your weight for example(moving 100kg is easier than moving 200kg), with the pace that you're walking(if you're jogging/burning you're going to burn more), etc. I'm not trying to nitpick, and rounding everything up is a good idea, but I'm pointing out that the math might be wildly off, specially if the person is a beginner and don't know what they're doing, and if you blindly trust it without weighting yourself you might run into issues.

Imo there's no reason not to weight yourself at least once a week, if you want to do it blindly for whatever reason then go for it, but you're just making your life harder for no reason desu
