Hi Claire.
I have doubts about keto longterm for myself. I use it to control blood glucose, because I’m afraid of one day becoming diabetic. At the moment, I know nothing better, though there’s something really bothering me.
But…
You need to see how it works for yourself. Every restrictive diet could potentially have a negative impact on one of us. For instance: suppose keto is bad for your kidneys (I’m not saying it is!). But: the main cause of kidney disease is diabetes. Keto can help lots of people control their blood glucose, therefore, avoid/treat diabetes therefore, potentially decrease the probability you’d develop kidney disease. Knowing your particular situation, you can adapt the diet to you, perhaps with some help from a doctor, if you’re following treatments, etc.
You’ll find two teams: the ones who are on keto and everything good that happens to them, it was keto who did it. It is like being part of some religion for them.
Team 2: they’re suspicious, or watched a video or read a blog of someone suspicious, then something bad happens… it was keto! Perhaps keto had nothing to do with it! Perhaps it was just genes, perhaps it was something they already had it and didn’t know it and keto was even keeping it from becoming worse.
We’ll never have answers to all of these questions about our health. Genes count for a lot. You have blue eyes, no matter what you eat.
So, keep a watch on your health. Keep an eye on your numbers, blood, urine tests. Be ready to be critical. Don’t automatically blame your diet, but also don’t assume it is perfect.
Besides eating, there are other things one can do to try to be healthy. It’ll help some. You can work on those, too, if you’re so inclined.
Be suspicious of vloggers, bloggers, internet doctors who sell supplements. Never accept everything they say. This whole thing became a way for people to make a lot of money selling supplements. Ironically, they’re always criticizing Big Pharma, so they’re easy to spot.
