You can't get a healthy meal at a fast food place

Sort of. The default combo, a cheeseburger, fries and a soda, grades D on the meal checker. A bowl with chicken, black beans, brown rice and salsa grades A, and so does a grilled chicken salad with beans and corn. Most fast food menus have both, and you have to order off the default to get the good one.

Why people believe it

Fast food means burgers, fries and soda to most people, and that order deserves its reputation. Sandwiches, burgers included, are the biggest single source of ultra-processed calories in the US adult diet, at 8.6% of everything adults eat. Sweetened drinks are third.

It’s also a big part of how Americans eat. On a given day between 2013 and 2016, 36.6% of US adults ate fast food, and 44.9% of adults aged 20 to 39. A rule that writes off a meal more than a third of adults eat on any given day isn’t much use to them.

The sit-down restaurant isn’t automatically the better choice either. When Tufts researchers measured 364 popular meals from local restaurants in 2016, they averaged about 1,200 calories, and the matching meals from big chains weren’t meaningfully different.

A simple way to picture it

A fast food menu works like a hardware store. You can build a solid bookshelf or a wobbly one from the same aisles, and the kit stacked at the front of the store is the wobbly one. The combo is the kit.

Four orders, graded

These are graded on the meal checker for a 170 lb person eating 2,000 calories over three meals, on the six systems Gyroscope grades a meal on. A plate that fits this person’s day is 500 to 830 calories.

The combo with water instead of soda is a C. A fried chicken sandwich, small fries and a soda is a D, and at about 960 calories it’s also bigger than the plate window. A loaded bowl with a cup each of white rice and black beans, chicken, cheese, sour cream and avocado comes to nearly 900 calories and a B. Half the rice makes it an A.

Why the bowl wins

A bowl lets you pick every part, and most of the parts are foods you could name, like chicken, beans, rice, lettuce and salsa. A sandwich comes as one item, and on the checker a fast food burger or chicken sandwich counts as ultra-processed as a whole, bun and all. So a plate built around one can never clear the Processing meter, and a plate that misses a meter can’t be an A. The two hamburgers do fine on Hunger and Nutrients, thanks to the salad, and still land on a C. A bowl or a grilled chicken salad can clear all six.

The 2025 to 2030 US guidelines say “When dining out, choose nutrient-dense options”, and to swap deep-fried food for “baked, broiled, roasted, stir-fried, or grilled”. At a counter, that means grilled over crispy.

The best case for the belief

The belief is right about the default menu, and the default is what most people order. On the checker, the cheeseburger combo clears only one of the six meters, Energy, because 740 calories fits the day. It misses Processing, Muscle, Hunger, Nutrients and Glucose. The checker also doesn’t count salt. If a person’s only fast food is the combo, “fast food is unhealthy” is a fair summary.

Since May 2018, chains with 20 or more locations have had to post calories on their menus. That makes the good order easier to find than it’s ever been. What to order when you eat out has the five rules for any counter, and the burger that beat the salad has the other side of the story.
