JJ Virgin says the scale lies because it can't tell fat from muscle. Extreme dieting and inactivity cause rapid weight loss that's mostly muscle, tanking your metabolism. Use a body composition analyzer instead to measure fat and muscle separately.
Using the scale is the worst way to measure fat loss because it's not going to distinguish between fat and muscle. So if you want to lose a lot of weight, you know what you should do? Sit on the couch, don't eat, and you'll lose a lot of weight, and it'll be from muscle. And that's the worst thing you can do to your metabolism. You got to ditch the scale and switch to a bioimpedance body comp analyzer that tells you how much your body is fat-free mass and how much of your body is fat mass so that you can make the right decisions for your metabolic health.
