In-N-Out vs Five Guys: Which Is Healthier?
If you are searching for In-N-Out vs Five Guys because you want the healthier fast-food option, compare the exact order — not the brand halo. Here is a fact-checked look at representative U.S. menu items and the trade-offs the headline numbers can hide.
Key takeaways
- The In-N-Out Double-Double is far lower in calories than the standard Five Guys Cheeseburger: 610 versus 980. But Five Guys’ Little Cheeseburger is also 610 calories, showing again that portion size can matter more than the chain name.
- One metric cannot tell you whether an entire restaurant chain is “healthy” or “toxic.”
- If the real goal is eating fast food less often, the habit matters more than winning a one-meal brand comparison.

Values are standard U.S. menu listings. Toppings, sauces and serving sizes can change the final order.
Standard burger vs standard burger: In-N-Out is lower in calories
In-N-Out lists the Double-Double at 610 calories. Five Guys lists its Cheeseburger at 980. That is a 370-calorie difference before fries or a drink.
The smaller Five Guys burger completely changes the comparison
Five Guys lists its Little Cheeseburger at 610 calories — exactly the same calorie figure as the Double-Double. If you only compare the largest default formats, you can mistake a portion-size difference for a brand-level health difference.
The fry comparison also favors the smaller In-N-Out portion
In-N-Out lists fries at 360 calories. Five Guys lists its fries in a much higher range depending on size. Again, serving size is doing a lot of the work.
So, which is actually healthier?
On the standard items, In-N-Out is lower in calories than Five Guys. But once you compare In-N-Out’s Double-Double with the smaller Five Guys Cheeseburger, the calorie result is a tie — a useful reminder that portion size drives the headline. The fairest way to use this comparison is to decide which metric matters to you, then compare the exact items and portion sizes you would actually order.
What does “more toxic” actually mean?
“Toxic” works as a social-media hook, but it is not a recognized score for deciding whether In-N-Out or Five Guys is healthier. Food safety, nutrition quality and long-term eating patterns are different questions. For a useful comparison, look at concrete measures such as calories, sodium, saturated fat, added sugar, fiber, protein, portion size and frequency — and avoid turning one number into a verdict about an entire chain.
