Now what

However, Weight Watchers lost approximately 100,000 subscribers on a sequential basis. The weight-loss company ended the second quarter with 4.5 million subscribers, including 1.6 million meeting subscribers and 2.9 million online subscribers.

"With continued momentum expected in the second half of the year, we have raised our earnings guidance for 2018."
