Have you lost weight by ditching certain foods?

I stopped drinking soda regardless if it's diet or not, and vending machine treats.

Other than most fries from fast food places, no. But it only works if cutting these foods out puts you in a calorie deficit.

I dropped added sugar and grains, as well as most fruits. Its limiting but I feel much better doing it so I'll continue.

I've tried it, and all that happens for me is I crave that food and feel like a failure if I eat it. I just try to eat as healthy as possible, living in the real world, and keep as close to my calorie limit for the day as possible.

My one exception for food I never eat is pizza. Pizza kills me every time. It makes me feel so sick and bloated and nauseated and gross. I have stopped eating pizza.

Nope. Eating all the foods, just less of them keeps me committed.

Not eliminating anything. However I have made it a policy now to not buy the family size bag of potato chips (kcmasterpeice bbq) but instead only the tiny single serve size. I can't and should not fit a whole family size bag in and i used to eat a whole bag regularly which is part of why I am fat. I will eat a bag full regardless if 1oz or 30oz. I can and do occasionally allow myself the 1oz bag. I am losing weight about 1.4 lbs a week.

I excluded nothing, but I did make more calorie conscious choices from the foods I enjoy and reduced overall quantity of food just for a while.

I prefer the approach of starting from what I should include rather than what to exclude.

Nothing, just eat less of it than I used to (95% of the time)

Yes, but mostly because I just ate too many calories of said food.

Ditching a particular food, or foods, is not by itself a panacea. If doing that causes you to lose weight, that only means that you've created a necessary deficit to lose weight.

Now for me, getting rid of regular soda (for the most part), which I was drinking the equivalent of about 6 cans per day, was a massively huge step. I would also actively look to eat foods that made the Coke taste even better - which only blew up my intake even more. It was very much like an addiction. I might drink a can of Coca Cola once or twice a week now, but after unlearning a bunch of crap, I am more in tune with CICO and I know when I can handle a treat now and then. It's freeing to know that I don't have to ditch a particular food if I am mindful of what goes in and what my calorie target is. I'm also aware enough to be very careful about the soda thing. It's always been the thing that, if I falter, I falter hard.

Bottom line: whatever the mechanism is, you'll lose weight by creating a deficit. If you can't create a deficit without ditching a particular thing, then ditch that thing. Ultimately, however, it's just math. Energy supplied and energy consumed.

No, I haven't cut out any foods.

Sadly, I've had to ditch alcohol for health reason. I do miss that good glass of red wine with dinner on occasion, but it is what it is... no point in whining about it.

Did it help my weight-loss? Maybe. I stopped before I joined MFP and I've been dry for nearly 1.5 years now. I did lose, but wasn't very successful at keeping those losses (with or without booze). It probably makes it easier to stick to my deficit since my 'one glass of wine' = 2-3 servings

Otherwise, there's foods I only have very rarely now (homemade Gorgonzola pizza for example) because those 800-900 cals per serving are pretty hard to fit in. I eat less pasta since my idea of a serving and the reality don't quite coincide, so again, I usually have a serving that satisfies me on days where I can fit it in.
