How to save up money/cut down on expenses in a „healthy“ way?

If full-blown piracy is too scary, start by at least using grey-market streaming sites for watching movies and shows 👍 c/piracy has a good megathread for sites: https://wiki.dbzer0.com/piracy/megathread/movies-and-tv/

Do you drive? If you live, work, and buy groceries within five miles distance, consider ditching your car and cycling instead. If you're nervous about how feasible this is, you can save on gas by keeping the car while you get used to riding. But the full savings come when you're not paying for insurance, parking, and maintenance of the vehicle.

~~Big talk~~ Unfortunately, that's a huge ask if you've never crossed a six lane stroad on foot. The American transit system is often downright hostile to anyone not in a car. It can be goddamn terrifying. Adding: If OP can get around safely and feasibly on a bike, this is great advice.
Otherwise, there are ways to cut down on car costs if you need one. What car you own matters. Get something extremely common that never breaks. A 1998 Camry or Corolla are probably two of the most solid cars money can buy and junkyards are full of them. Parts are cheap and available.
Learning to do your own basic maintenance will also save you lots of money.
A dealer might charge sixty bucks to swap a cabin air filter. It takes one minute and a replacement for my Honda Civic is eight dollars on Amazon. Same story with the engine air filter.
Check your oil and transmission dipsticks every once in a while for level and condition.
Check your brake fluid level and clarity.
Tire pressures are on the inside of the driver door jamb. Learn how to properly inflate your tires, including the spare.
If your car came with a scissor jack, a tire iron, and a compact spare, you can rotate your own tires in 30 minutes without buying any tools.
On an inline four cylinder engine, spark plugs are often on the top of the head, below a cover, and are insanely easy to replace. Just be aware of torque specs, especially on an aluminum head. A torque wrench can be yours for ten bucks at Harbor Freight.
Check your lights and blinkers every once in a while and learn how to replace bulbs. This is important on older cars that use halogen and incandescent lamps. A tail light is a few bucks, takes 15 minutes to replace, and will probably save you from a ticket.
Learning how to replace some parts is also a big plus and parts stores will often lend you small tools for some jobs free of charge.
Many states also offer discounted rates on yearly registration for older cars. In Oklahoma, it costs me $26 a year to tag my '97 Honda.
Finally, get a dash cam and the cheapest insurance you can, and drive like you're on probation and on thin ice with your parole officer.
- I've crossed a six lane highway on foot twice this year. That had little to do with my suggestion to consider cycling if OP lives in a denser area.
  Your suggestions on reducing car costs are good ones and I'm upvoting your comment because of them. But chill out, dude. We're here to offer OP advice, not take potshots at each other.

  Unfortunately you're right, I remember needing to take the car between the hotel and the Starbucks 500m away because there was a flicking big road on the way(which is insane for a European) .
  I don't get how American Karen don't get mad at their mayor for the lack of way to cross the street
Yep, owning a car costs thousands a year
I haven't owned a personal auto in a decade, and doubt I ever will again. The more you eschew our auto centric way of being, the more ridiculous it will look. When I see people in traffic now all I can think of is how fat, angry, miserable and lazy your passing motorists will look.
Everyone's got reasons they can't give up their cars, and unless you're a farmer they're almost all bs.
- I'm not going to put my wife's wheelchair on my bike as we travel, especially when it would be 5-6 hours by car to go to her dad's place.

Find out how much you're spending on what. That will let you determine whether the amount you spend on which things is actually worth it to you in the cold light of day, and show you where you can make the most effective cuts. Diagnosis is the first step: treatment without diagnosis is not helpful.

Tons of expense tracking apps out there that will download straight from your bank & credit card. You Need A Budget/YNAB seems t be pretty popular.

This is the true answer, especially for such a broad question.
You dont need to be fancy about it either. When I started I downloaded a years worth of credit card transactions and put them in a spreadsheet. I took the time to go line by line and assign a category for it.
Then I made a chart and could visually see where my money was going. On top of that I then calculated each category as percentage of my annual salary.
It's very eye opening. Even things that aren't an issue at least I now know that so don't need to feel worried/guilty about it.

It starts with understanding what you're spending money on. You can't control what you don't measure. Get some idea of what you are buying, be aware of the cost of things.

Even if you don't set down a full budget, you want to be able to go to the grocery store, say 'x dollars is all I need to spend' and then come out having spent less than that. If you don't know how much you spend on an average shop, that won't ever happen.

Second to this is any purchase that is a 'want' above 'y' dollarydos, sleep on it. Steam sale? Put what you want in your cart. Is it more than twenty bucks? Ok, no problem, I'll buy it tomorrow. Half the time you wake up and forget you ever wanted it. Sweet, money saved. Nice pair of shoes at the shop? Cool, I'll come back tomorrow and try them on. Gives you a chance to find it elsewhere, cheaper.

If you don't do it already then start to Meal-Prep and cook more at home instead of going out. Saves you a lot in the long term and it's usually healthier too.

I like this website for easy, cheap, sometimes healthy, meals
- Seconding this, have made many recipes from it and generally is my go to when first searching for a recipe.

Stop buying take out food. Since pandemic starts we now make all food at home. Last week we were out of town and had to stop on the way home for dinner, two sub's at subway was $26. Normally that $26 at our local independent grocer gives us more than a week of food.

You need to analyze how you are currently spending money. You can't know what to cut if you don't know what can be cut.

Learning where your money goes.

Fill your time with free things that you think are healthy. Walk. Invite friends over. Go to the library and get something for the night (book, movie, video game).

The more free things you do, the less time spending money.

Define "healthy", OP. Like, mentally healthy? That's pretty dependent on what your personal tastes are - the game is to find the things you can tolerate that most people can't as well, and to save on whatever those may be. Medically healthy? Aside from food most unhealthy habits are expensive anyway. If food, canned veggies are underrated, at least where I live.

One pretty universal thing, I guess, is not spending on the first thing put in front of you, metaphorically or physically. The entire surveillance capitalism and marketing economy is set up to part idiots from their money that way.

Create a household account book. Either use existing solutions like apps, go the excel / sheets route (I did) or use pen&paper with a calculator to help you out.

Learn how budgeting works in the first place. This step is REALLY important! I recreated my household account book two more times because I was an idiot who ignored learning the bare basics on money and accounting. There's a reason it's a profession with proper wordings and not some obsure hobby. Use youtube tutorials for that, as you will need several examples to understand budgeting in general.

Once you've got that down, measure your income and expenses over a year. Estimate your last year by category and type of expense, write reoccuring yearly and monthly expenses down. Create a saving expense to build up a budget buffer. You WILL need a buffer for all the variations you inevitably will encounter throughout a year. Once you understand how much you spent monthly to stay alive, calculate how much you can spent freely (pocket money). Ideally, put that pocket money on a separate account with a separate card as access to it and "pay yourself" that pocket money. Your main account should be the houshold expenses account with strict rules on spendings. It's also where all your income enters to finance it.

If you'Ve reached this point, you will need to let it run for a couple of months to work out a lot of kinks in it. Food budget, mobility budgets, health budgets, etc. all need to be tuned to fit your needs. Whatever's left goes to saving or pocket money. That's up to you. Set yourself a minimal safety savings point that will keep you alive for half or a full year without (relevant) income. That's enough buffer for most expenses you will encounter.

So after all of this you should have a good understanding how much you spend on what. That's when you dive deeper and look into each spending category, including food and rent (often the two major expenses). Cutting out or replacing certain type of foods or drinks with cheaper alternatives have huge impacts on your available money.

The rest should slowly become obvious if you've educated yourself enough to reach this point. It's all about learning and understanding, really.

Cook at home. Use mostly fresh ingredients. Staple foods are cheap... Rice, beans, etc

Beans and rice with oil and vinegar can hit the spot every day for lunch

Cold cut sandwich with fresh veggies. Bonus for homemade bread!

Eggs. Pasta. Eggs & pasta

For snacks, popcorn on your stove. Flavor with salt or spices. (I love Tajin!)

Keep a few spices in your kitchen. Have a decent olive oil and something high temp like grapeseed or vegetable oil

Avoid alcohol. If you must, don't drink in bars. (I'm alcoholic... I know it's hard to quit)

Learn how to properly operate your home's thermostat in summer and winter. Set it for automatic and dial in your preferred temperature. Leave it constant. This is vastly more efficient than turning it on and off and on and off.

Don't speed when driving a car. It takes more gas and can get you ticketed

Don't pay for TV or streaming services. Just pirate. Pirate games too. Books from libgen

For internet access, it may be best value to get unlimited mobile data and make a Hotspot for your PC

Have a specific savings plan. Set X% aside immediately after receiving each paycheck. If possible, get a high-interest account where you're required to make monthly deposits

If you have a hobby, hopefully it's cheap. If you can monetize it without killing your passion, go for it. If you have an expensive hobby, try to make enough money from it to offset the costs (I study fiddle. I busk to pay for strings, bowhair, and occasional lessons)

Consider leaving the US for a place that's cheaper or offers better terms. I left to teach English in Korea and China. Was able to save money and have a robust social life.

I like to divide my spending into two broad categories: needs and wants. For example, I need food and shelter to survive, but I only want that really cute blahaj (even though it feels like I need it). Things that I want I can skip, things that I need I cannot. You have to be very honest with yourself for that to work well though.

Of course life is not fun if you're only surviving, so it's OK to treat yourself occasionally with things you want. Just make sure you're saving enough before spending on "wants".

It's also often possible to break down "needs" further, since you may need some functionality (e.g. something to eat, something to hit nails with, etc.) but the specific item is not a need. I will prefer the cheapest option if I don't have any other requirements. I tend to like things that'll last though (they're usually cheaper in the long run), so I'm willing to not cheap out if that's a factor.

I am a very pragmatic and minimalist person though, so I don't think this advice will work for everyone.

So I don’t want to advertise an expensive product but the only thing that helped me finally save money and stop worrying about unexpected costs was You Need A Budget (YNAB). The concept is you put every single cent into categories like groceries, subscriptions, rent, put some aside for car insurance, saving for a new TV, and so on. And you also add every current, future and recurring transaction and connect it to the categories. Once you have this running for a few months it becomes second nature and you will not only be saving lots of money but also be ready for everything.

It has a learning curve but it’s worth it. There is a free alternative called Actual Budget, but you have to host it yourself and the UI is not great.

As an alternative to newspaper and magazine subscriptions, go to your local library's (website).

My library card allows me to access a bunch of newspaper and magazines online, and cost me just a very low yearly fee.

Quit smoking. Vapes and mix your own liquids is cheaper than tabacco or premade liquid/pods.

Stop going out to eat and or drink. Besides saving money you will probably lose some weight

Restaurant, bars and cafe can be a huge spending. You can also do a romantic dinner at home.

Check all your subscribed services you may find a cheaper competitor.

Before buying anything ask yourself about whether you really need it, and whether there is a used alternative available

If you do have money, set an auto transfert of 100-200€ to a saving account at the start of the month, you'll main account would feel empty faster.
