Flo’s Nutrition and Calories is a topic many diner fans look up before visiting this Route 66 staple. Flo’s is known for its retro diner atmosphere, but the calorie content of their burgers and milkshakes adds up quickly. You can still enjoy the experience if you know what to order and what to skip.
This guide breaks down the menu numbers so you can make a smart choice. We will look at the classic burgers, the sides, and the famous shakes. No judgement here, just the facts you need to plan your meal.
Flo’s Nutrition And Calories
Most people come to Flo’s for the large portions and the old-school vibe. The menu is simple, but the serving sizes are not small. A standard cheeseburger with fries can easily pass 1,000 calories before you add a drink.
If you are counting calories, the first step is to understand the base items. The patty alone is about 350 calories. The bun adds another 200 calories. Cheese and sauce push it higher. Let’s break down the main categories below.
Burger Options And Calorie Counts
Burgers are the heart of the menu. Here are the typical ranges you will see for the main sandwiches:
- Classic Single Burger: 550-600 calories
- Double Cheeseburger: 780-850 calories
- Bacon Deluxe Burger: 700-750 calories
- Chicken Sandwich (Fried): 620 calories
- Veggie Burger: 510 calories (but check the sauce)
The sauces are where hidden calories live. A single tablespoon of the house special sauce can add 90 calories. Ask for it on the side if you want to control the portion. You can also skip the top bun to save about 100 calories.
One common mistake is ordering the “large” patty without realizing it doubles the meat. That single patty is already 1/3 pound. The double is closer to 2/3 pound, which changes the protein and fat content significantly.
Fries, Sides, And Appetizers
No diner meal is complete without a side. But the sides are not light. A regular order of fries is around 400 calories. The loaded fries with cheese and bacon will set you back nearly 700 calories.
Here is a quick look at the sides menu:
- Small Fries: 320 calories
- Regular Fries: 410 calories
- Onion Rings (6 pieces): 380 calories
- Coleslaw: 180 calories
- Side Salad (no dressing): 90 calories
If you want to save calories, swap the fries for a side salad. That simple change saves you over 300 calories. You can also ask for a smaller fry portion. Many locations will give you a kid’s size if you request it.
Onion rings sound like a good idea but they absorb a lot of oil. They are fried in the same oil as the fish and chicken, which adds to the calorie density. They taste great, but they are not a light option.
Milkshakes And Desserts
The milkshakes at Flo’s are famous. They are thick, cold, and served in the metal cup with the extra shake on the side. A small vanilla shake is about 450 calories. A large chocolate shake can reach 800 calories or more.
The numbers get worse when you add toppings. Whipped cream adds 50 calories. A cherry adds almost nothing. But if you add caramel or hot fudge, you are adding another 150 calories per scoop.
Here are the average shake calories:
- Small Vanilla: 450 calories
- Small Chocolate: 490 calories
- Large Strawberry: 720 calories
- Oreo Blast: 850 calories
If you want the shake experience without the full calorie load, share one with a friend. Or order a “side” of shake, which is the leftover in the metal cup. That is usually about half the size of a small.
Pie is also on the menu. A slice of apple pie is 380 calories. A la mode adds 150 calories for the scoop of ice cream. The pie is good, but it is not a low-calorie finish.
How To Order A Lower Calorie Meal
You do not have to skip Flo’s entirely to stay on track. You just need a plan. Here is a simple step-by-step method for building a meal that fits your daily goals.
- Start with a single burger, not a double. This saves 200-300 calories.
- Ask for no cheese or a light cheese. This saves 100 calories.
- Request the sauce on the side. Dip your burger instead of letting it soak.
- Swap the fries for a side salad or a small fry. This saves 200-300 calories.
- Drink water or unsweetened iced tea. Soda adds 150-200 calories per refill.
If you follow those steps, a meal can come in around 700-800 calories. That is a reasonable number for a diner lunch. You still get the full experience without blowing your whole day.
Another option is to order a burger and split it with a friend. The portions are big enough. You can also take half home for later. That gives you two meals for the price of one.
Protein And Fat Breakdown
Calories are not the only thing to watch. The fat and sodium levels are high too. A double cheeseburger with bacon can have over 2,000 milligrams of sodium. That is close to the daily recommended limit for most adults.
The protein content is actually decent. A single burger gives you about 30 grams of protein. A double gives you 55 grams. If you are active, that protein helps with recovery. Just be aware of the saturated fat that comes with it.
Here is a simple breakdown for a classic single cheeseburger:
- Calories: 580
- Protein: 32g
- Fat: 34g
- Carbs: 40g
- Sodium: 1,100mg
That is not terrible for a diner burger. But if you add fries and a shake, you are looking at over 1,500 calories for one meal. That is most people’s entire daily intake in a single sitting.
Frequently Asked Questions
Does Flo’s post their nutrition info online?
Yes, most locations have a PDF or a printed guide. You can ask at the counter or check the official website. The numbers can vary slightly by location, so ask for the current guide.
Are there any low calorie options at Flo’s?
Yes. The grilled chicken sandwich (without mayo) is around 450 calories. The side salad with light dressing is about 150 calories. You can also get a lettuce wrap instead of a bun.
Is the veggie burger actually healthier?
Not always. The veggie patty is lower in calories, but it is often fried and served with cheese. The total can be close to a regular burger. Check the sauce and cheese to be sure.
Can I get a kids meal as an adult?
Most locations allow it. The kids burger is smaller and comes with a small side. This is a good way to control portions without feeling like you are missing out.
How many calories are in a full meal with a shake?
A double burger, large fries, and a large shake can easily reach 2,000 calories. That is more than most people need in a full day. If you plan to have all three, consider making it your only meal that day.
