A certified nutritionist and self-taught chef with a love for entertaining and experimenting with food, Lolita Carrico created Ketology after struggling for years with her own hormonal changes and weight gain. After having two children, she found that managing her weight and moods became more and more of a struggle. After researching the ketogenic diet thoroughly and understanding the science and nutritional aspects, she began her keto journey in 2018. Within three months, she shed 25 pounds and her mood improved, focus sharpened and her energy was through the roof. Four years later, she has maintained a 65-pound weight loss and has learned to intuitively follow a balanced keto lifestyle without sacrificing a thing!

We’re big on burgers in our household – and along with our standard Taco Tuesdays, we usually have burgers on Mondays. Last night, I decided to try to recreate In ‘N Out’s delicious spread for our burger night and it was a hit. All I really did was swap regular ketchup with no sugar added ketchup (Sir Kensington’s is my favorite) and instead of relish, I diced fresh pickles (also no sugar added) and added a bit of the pickle juice to the spread mix. Keto burger recipes are among the easiest and most satisfying keto meals — paired with jicama fries, keto burger night just leveled up!

We topped our burgers with bacon, caramelized onions and cheddar – and I added some chilies – wrapped them in romaine lettuce (or you can use your favorite lettuce wrap or cabbage leaves) and devoured! There are also some decent keto burger bun options – my favorite is SmartBUN or I make Cloud Bread, however I actually prefer the cabbage or lettuce wrap to a keto bun alternative! We also recently discovered frozen Wagyu Beef Patties at Costco that are our new go-to burger – if you can’t find the Wagyu version, their Grass Fed Beef Burgers in the frozen section are a great option to keep in your freezer whenever you get that burger craving!

Keto Burger Spread

This no sugar added spread is perfect on burgers and is almost exactly like In 'n Out's famous spread.
