Agreed that exercise helps as far as losing weight but cutting down caloric content and lowering your carbs and sugar is just as if not more important IMO. One can easily lose a ton of weight even with no excercise at all just by doing what I just mentioned.
I'll just use me as an example seeing I'm a pretty big guy. I'm 6'2" big frame and in October of 2019, I got up to 350 lbs....not a missprint. In HS where I played football I was 235 and even in college when you eat anything you see and typically at 2-3:00 in the morning, most I got up to was 250. So I've always been in pretty darn good shape.
Fast forward to 2016...I had just gotten divorced, my job wasn't going to great and so I slowly but surely started to eat and not give a crap...was pretty down in the dumps as far as my personal life was concerned.
Anyways in October of '19, I had finally had enough as I hated the way I looked and more importantly the way I felt health wise. So I went to a nutritionist and we went over my eating habits and it was decided that a keto style diet...no carbs...no sugars along with keeping caloric content around 1500 or so, would be the best way for me to drop the weight.
Well it worked smashingly. I dropped 50 lbs within first 4 months with no excercise to speak of and as of today as we speak after having joined a gym during covid, I am down to 270 with 20 more to go. But I feel and look as good as I have since my mid 40's.
Bottom line and why I even bring me up is if Becton wants to lose 30-40 lbs with no exercise, he easily can do it as all he needs to do is cut out the carbs and sugars for a few months and voila....he'd be down to 325-330 by time he was able to play again. And as I said earlier when I brought up this weight issue with him, a body his size cannot sustain the punishment that occurs in the NFL. He has to drop the weight otherwise and I hate to say it cause it would suck for all of us Jet fans, but Becton will be out of the league in a few years as he'll constantly be getting hurt.
Your point is well-taken that making wholesale changes in diet can lead to a significant weight loss on its own.
That said, and with all due respect, I doubt your 350 looked like Becton's 365 (correct me if I'm wrong). Becton and other NFL lineman may be fat guys, but they're not quivering balls of blubber--they're incredibly powerful individuals, many of whom could be power lifters if football hadn't worked out for them. They ARE in shape, just in a different sense that what we normally mean because they're not cut, they can't run fast 40's (some of them can, LOL), whatever. They're massively strong, agile, individuals.
So, maybe Becton
can lose 10 pounds in a few weeks while he's inactive by changing his diet; but what happens when he's back on his feet exercising? Lineman can't sustain their playing weights during the season while working out and practicing as NFL players do while
also focusing heavily on dieting. Or, they shouldn't try to. The off-season is the time to focus on a diet plan that helps you get down to a healthier weight/a weight the team feels you'd be at your best, not a 4-6 week surgery and rehab period. That's why we always read about how teams ask guys to come in at certain weights when OTAs start, and there's always a bunch of guys who come in overweight. The time to tinker with your diet and drop pounds is not in the middle of the season. And for Becton, this period is for him to focusing on coming back 100%. If he sheds a few pounds, cool, but that shouldn't be the focus and it's not even clear based on the injuries we've seen with him, whether that would even help him in any way.
EDIT: I also just wanted to add that of the injuries he's had since college--rolled ankle, that shoulder injury that the Jets totally botched, the weird chest contusion where he couldn't breathe, the plantar fasciitis, and know a dislocated knee cap--really only the plantar fasciitis would on the surface seem to be a direct result of him being a big guy. And with the plantar fasciitis, really anyone who has a high BMI is at risk of that. Becton would have to lose like 100 pounds to take himself out of that risk category which obviously isn't feasible for him as a pro. My point is, I think the guy is just injury prone. There's obviously reason to worry about him potentially getting bigger, but where is right now I don't think is a problem.
