Lifestyle change vs. diet

I'm 24F, 5'7" and weighed 244 at my highest. I started Keto mid January and I'm down 35 pounds and feeling amazing. Maybe once a month I'll have a meal that kicks me out of ketosis, but the cravings for anything high carb are gone. I thought the cooking aspect was going to be difficult, but due to more energy, cooking isn't much of a chore as it was when I was heavier. This is the only "diet" that has changed the way I think about food. I consider it a lifestyle change and don't want to go back.
