Low carb does not mean no carb

There is no such thing as a no carb diet. You can't function or retain muscle when you eat no carbs.

Having said that, low carbs works for a lot of people, though not everybody. The key to a low carb diet is that you have to get your fuels from somewhere else besides carbs, namely fats.

You can bacon, eggs, low-sugar chocolate, cream and milk, olive oil, nuts, seeds, etc. These fats are your fuels instead of carbs.
