Intermittent fasting isn't a diet; it's a pattern of eating that focuses on a period of time where you fast and a period of time where you eat. Whether you eat plant-based, low-carb, keto, gluten-free, or Paleo, anyone can do intermittent fasting with the diet they're already eating.
People find weight-loss success with IF because it's sustainable, and you never feel deprived because it doesn't require you to cut out food groups. It can also allow freedom from the strict calorie counting you may have tried in the past that made your diet feel too calculated and restrictive. You just want to be mindful not to eat 5,000 calories of pizza and candy during your feeding window and still expect to lose weight; you want to eat healthy, whole foods (more on that later) until you're satiated but not stuffed.
Another great thing about IF is that you can eat larger portions, which helps you feel more satisfied. IF is a lifestyle that you can use to both lose and maintain your weight, and from my personal experience, it feels effortless.
