As a personal anecdote, daily weigh-in was crucial for my (rather humble) weight loss - from 82 to 75 kg in about 12 weeks. I would weigh myself in at the same time - in the morning, before taking in any food or drink, but after taking care of the bodily needs. I never had the need to count the calories, so I have absolutely no idea what my calorie intake was while losing weight compared to normal diet. I do, however, keep a fairly consistent eating regime. So, the daily weigh in results were just used to adjust the size of portions a little bit here and there. It definitely helped.
