There is a lot of misinformation passed on decade by decade in the Fitness and diet industry. Hoping we can just squash some of them out of existence, but that's gonna take a lot of time based on how it's used to promote sales income.
I'll start though:
Drink a gallon of water a day: Does it help with weight loss? Well yes and no. It will help drop "water" weight more. But that's not the weight people really want to lose. It CAN help with weight loss if it keeps you from overeating by staying more full with water. But drinking a gallon of water will also have you going to the bathroom more and possibly increasing sweating.
Does it hurt to do it? Not really (unless your electrolytes aren't being replenished). But the myth of it being essential to do to lose weight is very overhyped and is a staple amongst many gym rats for some reason.
Throw in your myth and let's discuss

You have to "confuse" your body (either with diet or exercise) to lose weight.
Your body doesn't know what to do with processed foods and this somehow results in MORE of them being stored as energy than non-processed foods.
I forgot which thread I clicked on for a minute and I was about to write a rebuttal!
I do think that having some more vigorous efforts thrown into the mix is beneficial from a health and fitness standpoint...but IMO, unless you're specifically training for something, an overall active lifestyle is where it's at. And if you are training specifically for something, I would also think one would know how to train and would know that every training bout shouldn't be some crazy workout.
Most of the very fit and healthy people I know do "workout" some...but by and large, they are just active and enjoy being out on their bikes or hiking or rock climbing, kayaking, walking, going for a jog, etc.
Low-fat and fat-free versions of foods may have fewer calories per serving than their full-fat cousins, but (1) fat is flavor, so to make those foods palatable, manufacturers often add sugar; and (2) you'll gain weight eating anything if you eat more calories than you burn, so just because the cookie or ice cream or whatever is "low fat" doesn't mean you can eat as much of it as you want. You also need some dietary fat to properly absorb certain micronutrients (vitamins A, D, E, and K) - eating too little fat can lead to vitamin deficiencies that cause other health problems.

I so wish that calorie counting pill was available to us all! I hate counting!
Myth for sure: Cardio burns calories. If you're in deficit, with or without cardio, you'll burn fat. Cardio helps to create a calorie deficit and/or allows you to eat more if your calorie restriction to lose weight is low (say 1200 a day).
You see so many instructors, trainers, Youtubers, etc. telling people that if they aren't doing cardio, they aren't going to lose weight. Or that doing their cardio program will be how they will lose stubborn fat.

-Don't eat any ingredients that you can't pronounce.
-Only shop the perimeter of the grocery store, not the middle.
-Don't eat after 7pm.
-Don't eat white foods.
So much wrong...
I am a proponent of South Beach/ Med style eating as a way to build a healthful diet, but that doesn't mean you will necessarily lose weight if it doesn't help you control how many calories you are consuming.

Yeah, what? Whole grain bread is often delicious. If it's fresh I could absolutely polish off a loaf.

The common belief that HRmax is a heart rate that you *shouldn't* exceed, rather than one that you don't/can't exceed (absent a scary health condition, anyway).
So, so may things about HIIT: That you should do it daily, that it inevitably burns more calories in total, that the EPOC is extra-super glorious, that useful research findings about actual traditional CV HIIT apply to anything any trainer happens to want to call "HIIT", that everyone should do it every day . . . .
Veganism (purposely misusing the term here to mean diet only) or vegetarianism will inherently and inevitably cause fat loss, or are "healthier" than any form of omnivorous eating.
That the ubiquity of highly so-called hyperpalatable processed foods is a nefarious plot, and not a direct outcome of how large numbers of people vote with their buying dollars.
If we can broaden it out to health more generally, the idea there's a cure for cancer all the oncologists know about, but won't tell us, because they're cynical money-grubbers.
The way that too many gym trainers teach people how to use the rowing machine.
. . . and so, so much more.
But yeah, so many uniformed trainers just following the lead of another uniformed trainer.
There's a guy on YOUTUBE right how who advertises like hell and has so much broscience on all his videos. And people are eating it up. Vince Sant is his name and he host V Shred. Avoid.

Also, the converse of this: that not doing exercise to lose weight because you are focused on "getting healthy" or some such thing first is something to brag about from a health perspective. Worse yet, that you shouldn't do exercise until you have lost the weight
In the case of the bolded "rule" - the way most grocery stores are laid out, you'll find most of the whole foods around the perimeter of the store and most of the packaged foods in the aisles. I think it's a useful guideline for someone learning or re-learning how to shop for nutritious food, but yeah, there's nothing magic about it otherwise.
Also re: not eating after 7 PM, they call that intermittent fasting now and it's trendy.
I do agree with you on the "nothing you can't pronounce" and "nothing white" rules, though. If you just blindly apply the rule without trying to learn anything about what you're doing and why it works (or doesn't), that's the kind of anti-intellectual BS that got all your high school friends hitting you up to join their pyramid scheme and we could do with less of it, as a species.
Starvation mode
You must "earn" your treats through exercise. I actually saw on a "celebrity" personal trainer' IG account--along with his other celebrity trainer friends--wearing shirts that said "Earn Your Booze." I mean, just all of it was weird, if not in poor taste.
