Once you’ve made it through the first week of keto and you are in ketosis, fat will steadily fall off your body (as long as you are in a calorie deficit). The average weight loss at this point is around 1-2 pounds per week — the majority of it coming from fat. As you get closer to your goal weight and your overall body weight decreases, weight loss will slow down. This happens because as your weight decreases so will your daily caloric needs. For this reason, you may want to recalculate your calorie needs every month or so. Keep in mind that weight loss may not be consistent either. You might have some weeks where it seems you haven’t lost anything — then you’ll weigh yourself a week or two later and be down 3-4 pounds.
