Just because your weight loss is over it doesn’t mean you should get lazy or apathetic about what you eat. You should always know what you’re fueling your body with. Keeping weight off is just as much of a challenge as losing it all. Some convert over to a Paleo-style diet ( /r/paleo ) and focus on whole foods without grains, refined sugars or refined fats. Others will gradually include more carbs by into their diet by 5g/week until they find a point where their weight maintains itself. Doing a ketogenic diet should be part of a new lifestyle change, and you should always avoid going back to your old eating habits.
