When blood sugar drops after a low-carbohydrate meal, the hormone glucagon is released which causes triglycerides to be released from the body's store of fat. Glucagon also causes the liver to break the triglycerides into glycerol and free fatty acids ...
The glycerol part of the triglyceride provides about 7% of the fat calories as glucose, but this is not enough to maintain my blood sugar level. The balance comes from the breakdown of protein from the food thats been eaten.
Meanwhile, the free fatty acids are cut into two- and four-carbon fragments called ketones or ketone bodies. Ketones are normally present in the bloodstream, but when their concentration exceeds 70 mg/dl, they start to appear in the urine - this is "ketosis."

So to answer your question, it depends what else you are eating but for the most part, yes, your body will go back into ketosis after that because dietary ketosis is a natural adjustment to the body's reduced intake of carbohydrates as the body shifts its primary source of energy from carbohydrates to stored fat.

When you make a boo boo, get out and exercise ASAP. That's what I have had to do on more than one occasion, but never had a problem getting right back into ketosis within a few hours. Of course, we're not talking about an all out candy or pasta fest type boo boo. Those can really knock you back.
