Specially processed meat, cheese and bread. In the case of fast food these ingredients are basically "hacked" to make us crave more and consume more. These industries have "food scientists" working on exactly that.

Meat, cheese and bread in their more natural form is definitely healthy when consumed in moderation.

It seems odd putting meat in the same category as bread.

In terms of pure health, there's not much out there better than most meats. Yes, beef is a bit lower than pork and chicken, but properly portioned (looking at most of us Americans) it has very few downsides.

Bread on the other hand can be one of the worst foods we can eat. Of course, it is still all about moderation.

EDIT: Why the reddit-like downvotes folks? There's really no cohesive argument that puts meat below bread healthwise in most situations. If you want to avoid meat, avoid meat. If you want to be morally opposed to anyone eating meat, so be it. Facts are still facts and misinformation isn't the right way to fight that battle.

Well, they sure have necessary nutrients

I'm sick of people claiming calorie dense food is unhealthy. It's not. Calories are required for your body to function. An adult needs 2000kcal per day; whether they are spread out over 8 meals or 3 makes no difference. Eating the amount of calories of a hamburger every day is nothing special, especially if you do sports regularly.

This comment was made by the <20 BMI gang.

Additionally, eight ounces of steak might be lean. (It also might not, of course.) Eight ounces of hamburger, especially one from a fast food restaurant, is absolutely not lean beef.

First of all there's a huge gap between home made hamburger and, well, anything else tbh. Actually, let's expand it, there's a huge difference between home made anything and any other kind of food, be it restaurant or assembly line made.

Backing up a little though, if you make a hamburger at home, with lean good quality beef that you grind up yourself or ask them to grind it for you at the counter, lots of veggies and very little oil, on a home made bun or on actual bread (the kind made with flour, water and salt, that's it), then it's quite healthy. Still wouldn't eat it more than once a week since red meat yada-yada, but still, not that bad.

What you get at a fast food though is very low quality meat with lots of fats, dipped in other fats, sugar and spices to mask the flavor, processed bread, processed cheese, very little veggies and, usually, a side of french fries and a soda, which are a meal onto themselves. Let's take McDonald's, looking at their website a quarter pounder is 500+ kCal, the medium fries are 300+ kCal and a medium coke is 200+ kCal. That's 1000+ kCal for a "meal" full of fats, sugar and processed food. Also it's a huge spike in insuline which will lead you to a huge crash just a few hours later leaving you hungry and craving for more.

Restaurants are also a bit guilty of this. They tend to add much more fats than you'd ever do at home in order to drastically improve the flavor of their dishes. Can't even fault them for it, if I wanted a bland healthy meal, I'd have eaten at home. If I'm going to the restaurant it's because I want a great tasting dish. Ready made meals you can get at a supermarket are also full of fats, vegetable oils and preservatives in order to mask the shitty flavor.

So at the end of the day I'd say the best thing is to avoid as much as possible processed foods, avoid all take outs and deliveries, go out to eat maximum once a week and cook all your meals yourself starting with simple ingredients. It's not that hard either and cooking can be fun.

Beef ain't healthy, White bread isn't either and don't forget, the McDonalds Cheesburger doesn't even have vegetables.

Burgers aren’t inherently unhealthy, in moderation. The problem comes when you’re buying the burgers from fast food joints.

Because the stuff is heavily processed using a lot of sugar, saturated fats and salt. Also the gravy the meat is fried in. Also the poor quality of the meat, being made from god knows which scraps of the animal, that couldn't sell otherwise.
