Like Louis Koo, he lost 30 pounds in three days. But stars have better subjective and objective factors in slimming than we do. A star lives subjectively by his appearance, so his figure is related to his future and survival, so they will have a stronger initiative in slimming. Objectively speaking, stars have more resources and concentrated time, and can continue to lose weight in a short time, thus achieving the goal of losing weight. For example, many stars use a lot of products, which are very high-end and difficult to see in the market. Secondly, they can allocate their own time, unlike we have to go to work every day! So being a star will be much easier than us!
