low carb question

If you're eating significally less carbs than before, it would be considered low carb. A gradual reduction of carbs is the best approach. Just remember to replace the carbs with fats instead. There are many low carb approaches, from keto to paleo/primal. I would research each option and then go with what you think is best. I personally am on a keto approach to low carb, and I love it. It's so much fun to try out new recipes.
