I agree with that. It’s hard to change. I’ve been low carb over 5.5 years now, and still look at fat with disdain at times, remembering the 30+ years of low fat I did. I spent decades eating hot cereal for breakfast (no fat), pasta for lunch, and brown rice and beans for dinner, with a snack of rice cakes. Add some chicken breasts without the skin, white egg omelettes, and that was me.
I’ve been doing this so long, I don’t remember being a newbie. In my time, I’ve tried eating paleo, low carb, keto, resistant starch (no benefits, in fact I think high fiber is bad), many different vitamin regimens (don’t take anything other then vitamin D and magnesium), iodine (too much seems bad), dairy/no dairy (still eat dairy), yogurt/no yogurt (like dessert for me, so avoid), nuts/no nuts (I try to avoid nuts), high fat/high protein (like higher protein better), fasting longer/fasting shorter (still try both at times), … Many more I can’t remember right now.
I think the issue for me is the sheer number of the same posts over and over again. And the idea that keto (or any diet) is going to undo 10, 20, 30, 40 years of different eating in a short time. It won’t. I’m still losing weight and gaining muscle, albeit slowly, after 5.5 years. You do see some people who lose amazingly quickly, but I’m not one of those.
And while I like people like Dr. Fung, his website (and others like it) can be disheartening at times. He typically has the “star” people on it, who are fasting 42 hours 3 times a week and fasting 5-7 days once a month. Or you’ll see “How Jimmy [or substitute a name here] lost 100 pounds in X months!” [put a ridiculous value for X months]. When I read these, even I can get upset, when I try to fast 36x2/week and only make 36x1 and 22x1 or I fast 4.5 days only once every three months or more. Or I compare my weight loss with theirs and can’t figure out why I’m not losing faster or not at the weight I was when I was in high school/college.
Then I realize I’m 30+ years older, I have one repaired completely torn rotator cuff and one currently completely torn rotator cuff, 30+ years of insulin resistance, 30+ years of NAFLD and FLD caused by excess alcohol and sugar… But because everyone puts their star pupils in front of us, we all think that’s what others can do, when in reality, it’s not what most people do.
