OP: Asking Apple people why you should buy Apple products is going to get a LOT of Apple marketing. They are readily giving you what you are asking for... but whether that is best for your family member or not is not necessarily in full consideration.
A different question: does he
NEED an Apple Watch for some reason? What if this was a decade+ ago when there was no Apple Watch? Could he work on his health without it? Of course he could.
A watch is not necessarily going to do a thing for improving his health. Yes, there are certainly features & benefits that can support an overall goal of improving health... but that can be said about ANYTHING you/he could buy aiming at the same target:
- A program that provides better food choices?
- Home equipment so he can fit in some health-improving activities OUTSIDE of the gym?
- Social activities/clubs that mask health benefits by building them into activities like kayaking/hiking/skiing/biking/etc and/or (healthy) cooking classes, etc. While interacting with others, he's getting exercise at the same time... a kind of stealth way to better health.
- A dog... because Spot needing a walk at least a few times a day means Spot's owner will need to take a walk a few times a day. Even bending down to pick up Spot's regular poos is guaranteeing at least ONE squat a few times each day. Apple Watch will never need a walk or a poo, so while it has potential to help him get more exercise, he could also park it in the corner like a piece of furniture and never get the intended benefit. A dog MUST poo. You cannot park a dog in a corner.
I share this NOT to put down Apple or Apple Watch but to point out that you could put the same kind of money towards many other things and potentially make more of a difference. Tech is not the answer to everything. And weight-loss in particular is much harder than strapping on a bit of tech and hoping it can motivate someone.
- Good supporting tool? Yes.
- Good solution? That mostly depends on him.
- Best way to help him with this? Maybe... but the same money could buy lots of other things that might better get him moving, eating better, etc.
Find some stealthy activity that he likes to do but lacks a potential "gift" to let him do it now. For me, that was bicycling. I didn't even have a bike for about 20 years but now I try to do all local travel on the bike (even grocery runs, etc) and leave the car parked in the garage. Golf (clubs)? Hiking (if this, maybe a weight vest to wear while hiking)? Skiing? Skates?
Check out Hobie Kayaks with their pedal-based "rowing". Maybe he has a stealth "workout" hobby he really likes but lacks some key bit of equipment or materials? Paint ball war games with some buddies (which can actually be quite a workout)? Nearby amusement park season/annual pass (walk around one of those for a day, and you get a workout)? Tennis? Pickleball? There are soooooooo many possibilities.
In short: think about what will actually get him moving vs. what
MIGHT get him moving. Watch has great potential but nothing about it will push him to "get with it" unless he applies self motivation. You can't shoot one buddy with a paint ball without actually getting out there and "hunting" that buddy. That Hobie won't row itself.
Especially if you can make it a
SOCIAL thing though, the fundamental desire to socialize can become motivating to "get with it." You can't flirt with the pretty ladies in the Paddle Board group if you are not out there on a Paddle Board with them. You can't win the over 50's rowing team trophy if you are not out there rowing with the team. Etc.
