I've had a few friends and family members that had joint pains that were cleared up from going keto, too. Even if they didn't stick with it, that initial month or 2 was enough. I always highly encourage anyone who has those types of pains to just try it for a month and see. It sucks, but to me it would be totally worth the sacrifice.
Totally worth it. The mainstream foods they sell to people en masse at grocery stores is borderline criminal.
Like "here, shorten your lifespan and ruin your quality of life with this!"
Coca Cola for example is as bad as smoking, and people feed that to their kids for years. Sugar is strongly linked to reduced cognitive function. Highly processed foods lead to heart issues.
So when people go full cold turkey from all that garbage, the relief your body feels is massive.
That's because you're not burdening your body with crap during Keto. It can allocate resources to healing properly. Plus you're also supplying it with the optimal nutrients it needs to accelerate the process.
The body is designed to and want to heal itself. You just have to let it work.
With my neuropathy I can tell after one day if I made the right decisions. When I had serious stomach pain a few years ago, I also knew right away if I'm eating foods that are doing more harm than good.
The problem is that the body is built to withstand a fair amount of negligence. We don't really pay attention to the harm that's being done until the damage becomes obtrusive to our daily lives.
The times I've done keto since, it's not the same, though. I don't know if it's because I don't eat quite as bad as I used to before the first time I did it or I'm not quite as strict or what.
Probably a combination of both, yeah. You may not see the results short term as much but long term you'd reap the rewards.
