I am LCHF I've dropped from 14.5 stone to 13 stone and need to lose another stone (14lbs) I'm not diabetic but before LCHF might have been close.
More conscious than ever of confirmation bias. When I first saw the Tsimane study suggesting carbs were OK I had to try very hard not to just dismiss it then worried that I had been pushing LCHF too hard. Zoey Harcombe explained well for me the Tsimane carbs were guessed not measured.
However, like anything the more deep you go the less clear things get. The things I've seen subtle changes on are:
Calories were irrelevant because your metabolism goes up with high fat high but now calories are relevant, even on high fat if you want to reduce body fat.
Too much protein is bad now meat only OK, this was based around protein spiked insulin. But that spiking view I think is slowly shifting.
Atkins was sort of right but later went for high protein not necessarily high fat so was wrong, but as above point that might be changing.
I've recently heard Dr. Ted Naimen say losing weight on calorie restriction or LC are both beneficial massive simplification of what he said.
LCHF isn't Ketogenic for about 6 months after I started I thought they were the same.
In the near future I think there'll be subtle shifts on Fasting, I've done 6 day fast where I had cream coffees twice a day, I think that will change to saying fasting means no calories. Also, I wonder whether the Autophagy thing will weaken.
Cancer, Dr Seyfried says it can reduce tumours others suggest it can help chemo etc work more effectively but Low Carb won't directly help with cancer. Way too an emotional area to get any clarity. And how do you even do RCTs on this.
I am a massive advocate of LCHF. The N=1 is a way to dismiss the above and is how anti-LCHF can say it doesn't work for the majority.
When I find people laughing at LCHF/keto I get annoyed my reaction worries me, am I becoming a zealot? Suffering from confirmation bias?
I am generally sceptical about everything. So when I hear all these wonderful things about LCHF I need to say where's the evidence. Is there evidence of better skin, shinier hair, more energy, clearer thinking, less sleep.
I've got in to debates with nutritionists who say weight loss/gain, eating issues are very complex. I did dismiss this attitude but I now agree with them a little more.
My view is LCHF clears away many confounding factors. Then you can add the n=1 factors to tweak, the dudes say hack, your diet to deal with our individual complexities.
Perhaps we'll see more carbs being allowed or perhaps zero carbs will be the future or maybe we've finally cracked it. I'd like to try living only on meat. But I don't feel I know enough about a meat only diet yet.
So in summary when you personally see all the benefits you really want everyone to do the same. I used to then go in to lecture mode - very bad idea. Worse is when someone on calorie restriction tells you they've lost a stone in weight so LCHF is no different. I now smile and say whatever works for you keep doing it.
I used to then ask a month later, how's it going, which annoyed them because the weight loss had stopped (although to be fair I haven't lost any weight in a year now despite multiple fasts).
Now I am more open minded and listen better. I ask how did you feel on low calorie what did you eat what other changes did you notice.
I try to find common areas with them, all the time fighting hard to not go back to lecturing them even when they ask more about LCHF or worse tell me LCHF is a fad
