How are weight loss companies biased to sell their products?

Diet and weightloss advertising puts super skinny models and actors/actresses saying they lost an insane amount of weight using their product. That is completely bias because they aren’t just going to say the model lost weight through other methods of weight loss because they are advertising THEIR product.

I would use skepticism evaluating these ads because I would be skeptical believing that someone lost 200 pounds in 2 months drinking some supplement.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
