Is Fast Food Bad for You? What 1,004 Meals From 19 Chains Actually Show

Fast food isn’t automatically bad for you, but sodium is the real catch. Of 1,004 meals we checked from 19 chains, about half are 600 calories or less. But 1 in 7 has 2,300mg of sodium or more, a full day’s limit in one order.

This is for anyone who eats fast food and feels low-key guilty about it. Instead of vibes, we looked at the actual numbers from official nutrition guides, so you know what’s really going on.

What is “bad” when people ask if fast food is bad for you?

When people ask “is fast food bad for you,” they usually mean one of three things. Too many calories, too much sodium, or not enough protein and fibre, so we checked all of it.

We used the Pleit database: 1,004 whole meals from 19 chains in Canada, from each chain’s official published nutrition guide, as of November 2026. No estimates, no guessing.

The short version is that fast food has a range like any other food. Some orders are genuinely solid, and some are a whole day of salt in a box.

Pleit exists for exactly that gap. It shows you the numbers before you order, so you can pick the solid ones when you want to.

Is fast food bad for you? Here’s what the numbers say

Calories are less scary than you think

About half of the meals, 526 of them, are 600 calories or less. The middle meal sits right around 600 calories, which is a normal-sized dinner for most adults.

Protein is actually decent

42% of meals have 30g of protein or more. Rotisserie and grilled chicken do most of the work, like a St-Hubert rotisserie chicken breast with 56g of protein in 400 calories.

Sodium is the real problem

Health Canada recommends staying under 2,300mg of sodium a day, and Canadians already average about 2,760mg, per Health Canada’s 2017 report. The middle fast food meal has 1,230mg, more than half the daily limit on its own.

The good news is that a third of meals have under 1,000mg. So it’s less “fast food bad” and more “check the sodium on the order you’re about to get.”

Fibre is where fast food falls short

Only 29% of meals have 5g of fibre or more. If you eat fast food a lot, getting fibre from the rest of your day matters, or pick bowls and wraps that have beans and vegetables.

How do you make fast food better for you?

You don’t have to quit it. Pick orders with protein, watch the sodium on the big combos, and add something with fibre when you can.

Swaps help too. Grilled over crispy, regular over large, and water instead of a large pop all cut a lot without changing where you eat.

And honestly, a greasy poutine on a Friday isn’t going to ruin anything. It’s what you do most of the time that adds up.

How does Pleit help you choose better fast food?

Type what you want, like “fast food that wont wreck me” or “low sodium fast food,” and Pleit gives you three orders with protein and calories. It uses the same 1,004 meals from official chain guides.

It doesn’t lecture you either. Ask for the greasiest thing near you and it’ll find that too. Pleit doesn’t deliver, so you order on the app you already use.

Ask Pleit on the homepage for a fast food order that fits your day.
