7 Keto foods from Sonic Drive-in
1. CRISPY TENDERS (2 PC.)  
10g of Fat, 15g of Protein, and 11g of Carbs, 190 Calories
Although this is a small snack and probably won’t fill you up, this only has 11g of carbs. Perfect if you’re fighting the hunger pangs and need something to hold you over! Avoid any sauces, the 11g of carbs is solely the chicken.
2. QUARTER POUND DOUBLE CHEESEBURGER (without the bun)
34g of Fat, ~10g of Carbs, 31g of Protein, ~250 Calories
If you take off the bun and order it with no sauces, the Quarter Pound Double Cheeseburger is a delicious meal without too many carbs while also supplying a large chunk of your daily protein and providing a decent amount of Fat.
3. CLASSIC GRILLED CHICKEN SANDWICH (without the bun)
22g of Fat, ~10g of Carbs, 30g of Protein, ~200 Calories
Like the available burger choices at Sonic, the grilled chicken sandwiches follow similar rules: no buns and no sauce, and you have a good Keto meal. The grilled chicken doesn’t supply as much fat as a burger will, but typically, the chicken is going to give you slightly fewer grams of carbs. It’s a great choice if you’re trying to fit into strict macros
4. CRISPY TENDER DINNER 3 PIECE
14g of Fat, 16g of Carbs, 22g of Protein, 260 Calories
If you’re wanting some chicken tenders, but the 2-piece meal mentioned earlier doesn’t seem filling enough, you can upgrade to the 3-piece order. Surprisingly, the breading won’t put you over on your carb intake, but you will need to watch your macros for every other meal during the day. Don’t eat French fries or use dipping sauces, though!
5. HOTDOGS (except the Chili dogs, and no buns)
~25g of Fat, ~10g of Carbs, ~12g of Protein, ~200 calories
The Hot dogs at Sonic are top-notch, and they offer a large variety. If you forgo the bun and don’t order any of the chili dog variants to avoid those pesky beans, you should be good to go on ordering one from your local Sonic. Try to order it without Ketchup or Mayo for even fewer carbs!
6. BUFFALO BONELESS WINGS 6 PIECE
22g of Fat, 17g of Carbs, 29g of Protein, 440 calories
The staple of any good get-together, wings from Sonic Drive-in are super tasty. Surprisingly, you can fit a 6-piece Wing meal into your diet! Just remember to not use those sweetened sauces and don’t go overboard when eating the breading, and the wings can be a tasty meal while not breaking the Carb bank. If you must use sauces, a rule of thumb that many people use is that the hotter that a sauce is, the less carbs it has, so go for the hot sauces!
7. Grilled Chicken Wrap
14g of Fat, ~12g of Carbs, 31g of Protein, 480 of calories
Skipping out on the tortilla, a Grilled Chicken wrap can be a filling meal while not putting evil carbs into your body. Be sure to watch out for the ranch dressing or other potential carb-filled ingredients that might be included on this tasty meal!
Things to Watch Out For
If you’re on a strict Keto Diet, and you must eat fast food from Sonic, be on the look for the sauces used on your food. While a burger will not knock you out of Ketosis, a glob of ketchup or ranch can very easily put you over your limit. Be sure to ask for no sauces or at least be sure to request that the sauces be on the side.
It should go without saying, but do not eat any of the combo meals! The fries, tater tots, and whatever else you may order with these meals will very quickly and easily put you over your daily Carb limit!
Also, be aware of the temptation of being around Sonic’s awesome food. It may sound silly to a lot of people; however, being surrounded by constant advertisements of mouth-watering shakes and ice cream can eventually wear down even the strongest Keto warrior. Be sure to be stay strong and make your visits quick to minimize the temptation of eating anything that might introduce extra Carbs into your daily intake.
